REQUIREMENT ANALYSIS

1.1 Introduction

This project aims to develop a secure software to transfer data through a network. Here we use fingerprint authentication for identifying the correct user and send the encrypted data to another user. A user may be a person or a computer in an industry. This software supports Microsoft Word (DOC), Rich text (RTF), and Text file types (TXT).The user can print the report of data.

The purpose of our software project is to design a Fingerprint based Data encryption system to transfer encrypted data through a network ie, data security is the main aim behind this application software . There are several benefits of doing this. First, a user can send their confidential data to another user using their biometric features. This system is developed for the communication of persons working in an organization in secure manner with the help of their fingerprint. This software is useful to many organizations, including the Police department. There are number of persons working in an organization, are allowed to use the system. The interaction is provided through a client server application. Users in the system are classified into different levels, based on the categories they have given different privileges by the super user. The members in an organization can transfer files among themselves. The files are accessible only to authorized persons.

This software will be a client application built on the C#.net and Oracle platforms. The interface of the software will be clean and intuitive to even non-technical users. As the system is handling, highly sensitive information, security is very important in the system. To keep the data highly confidential security measures are adopted to prevent unauthorized access. for eg: Employee can be able to send the confidential messages with the help encryption to his/her superior officer.

This software includes the following features

· A secure login and registration system using fingerprint authentication, which allows only the users in that organization to access the systems.

· Transfer the confidential data to other users ,and the end user can print the delivered data.

· Here RSA algorithm is used for data encryption.

1.2 Feasibility study

The feasibility report of the project holds the advantages and flexibility of the project. This is divided into three sections:

· Economic Feasibility

· Technical Feasibility

· Operational Feasibility

· Behavioral Feasibility

1.2.1 Economic Feasibility

A systems financial benefit must exceed the cost of developing that system. i.e. a new system being developed should be a good investment for the organization. Economic feasibility considers the following

i. The cost to conduct a full system investigation.

ii. The cost of hardware and software for the class of application.

iii. The benefits in the form of reduced cost or fewer costly errors.

iv. The cost if there is no change (i.e. the proposed system is not developed).

The proposed “FINGERPRINT BASED ENCRYPTION FOR CONFIDENTIALITY AND AUTHENTICATION” is economically feasible because

· The system requires very less time factors.

· The system will provide fast and efficient automated environment instead of slow and error prone manual system, thus reducing both time and man power spent in running the system.

· The system will have GUI interface and very less user-training is required to learn it.

1.2.2 Technical Feasibility

Technological flexibility is carried out to determine whether we have the capability in term of software, hardware, personal and expertise to handle the completion of project. It centers around the existing computer system (H/W and S/W) whether it can support the addition of proposed system, if not, to what extent it can support.

The H/W and S/W required in our system are easier to install and handle. The necessary H/W configuration and software platform is already there. The system supports interactivity with the user through GUI. So our system is technically feasible.

1.2.3 Operational Feasibility

Operational feasibility determines how much effort will go in the proposed system, and in educating and training the users on the new system. Operational study strives on ensuring that the equilibrium of the organization and status in the organization are not disturbed and changes are readily accepted by the users. The proposed system is operationally feasible because it does not require any training for the users.

1.2.4 Behavioral Feasibility

An estimate should be made of how strong a reaction the user staff is likely to have toward the development of a computerized security system. It is common knowledge that computer installations have something to do with turnover, transfer, retaining and changes in employee job status. Introduction of this software does not require any special effort to educate and train the staffs because this software is not so complicated and easy to understand.

1.3 Project plan

Our group consists of three members and we worked together according to a detailed plan to ensure quality in all aspects for assigning tasks to each member clearly.

1.4 User Interviews

In order to understand about the secure data transfer through a network, requirement analysis had been conducted at Bank of India,Beypore.

By describing the great process in details, we can divide the entire process into three major processes.

1. Fingerprint Authentication.

2. Data Encryption.

3. Transferring the encrypted data through a network.

4. Data Decryption (the encrypted data is decrypted and the authorized user can access it).

5. To obtain the view of decrypted data to the user (eg: employee data).

6. User can print the reports (e.g.: data).

1.5 Existing system

The Existing system is a manual system in which each user has a username and a password.

Since it is mandatory, there is a chance of an unauthorized user to access the system. As a result it is highly insecure. It has low efficiency and time consuming. In highly sensitive data that can be sending using primitive methods are very insecure because it can be easily interrupted by externals

1.5.1Disadvantages

· Manual transaction

· Insecure

· Low efficiency

· External interference(Hacking)

1.6 New requirements

New requirements needed for the working of FECA is we need a fingerprint reader which is compactable with windows xp.

1.7 Proposed system

· High security

· High efficiency& Accuracy

· No external interference

· Support wireless/wired data transaction

1.8 Requirement analysis

Requirement analysis is a process of understanding the customer needs and expectations from a proposed system or application and is a well-defined stage in software development life cycle model. This provides a software for the user who wish to securely transfer data through a network, which is more reliable, user friendly and thorough interaction with the database.

Requirements are the description of how a system should behave or a description of system properties and attributes. It can alternatively be a statement of ‘what ‘an application is expected to do.

A dedicated and specialized requirement analyst is best equipped to handle the jobs. The requirement analysis function may also fall under the scope of project manager, program manager, depending on the organizational hierarchy.

1.9 The overall Description

This software is mainly aims the confidential data security. The main requirements for this includes the number of users and their job types, registration methods, encrypting algorithms, identifying algorithms etc..

The most of the fingerprint scanners (reader) support only 660 fingerprints, so there is some problem occurs when the number of users (Employee’s) in an industry greater than 660.We can solve this by saving the templates into our PC.

1.10 Product Perspective

In this method data are encrypted using public key encryption method .Fingerprint authentication is used to login and decrypt the data. This system encrypts the data and only the authorized person can be able to view the data using their biometric features. This application more concern with the data security or data security is the main aim behind this application software. In this method, each user will be provided public key and private key .Using public key user encrypt his/her confidential data and after encryption the cipher text will be send to another(receiver) user. For data encryption, RSA algorithm is used ,Here we use 1024 bit RSA encryption .A RSA key length of 1024 bits is sufficient for many medium-security purposes such as web site logins etc.. Its main application areas includes the Police department,Court,Secret service departments, Industries , Educational Institutions etc..

The main functionalities used in this project are:

· Fingerprint Authentication.

· Data Encryption.

· Transferring the encrypted data through a network.

· Data Decryption (the encrypted data is decrypted and the authorized user can access it).

· To obtain the view of decrypted data to the user (eg: employee data).

· User can print the reports (e.g.: data).

Performance: First, the easy bit. Figure 1 shows the time taken to encrypt various numbers of 16-byte blocks of data using the algorithms mentioned.

fig 1.1

1.11 System Interface

In this project we include a fingerprint authentication system, it improves the quality of product.

If our system includes a fingerprint reader, we can use biometric authentication in addition to standard authentication via login and password. After registering their fingerprint, users can log in to the system either by swiping a finger on the fingerprint reader or by typing in a password.

1.12 Interfaces

In this system the interface between the user application (software) and the fingerprint scanner is introduced in login section (before encryption/decryption).Here we use serial port to connect fingerprint scanner.

1.12.1 Hardware Interfaces

In this project the main hardware is fingerprint scanner. The main functionality of a fingerprint scanner is to scan the user’s fingerprint and produce exact pattern of that fingerprint. Most fingerprint scanner systems compare specific features of the fingerprint, generally known as minutiae. Typically, human and computer investigators concentrate on points where ridge lines end or where one ridge splits into two (bifurcations). Collectively, these and other distinctive features are sometimes called typica.

The scanner system software uses highly complex algorithm to recognize and analyze these minutiae. The basic idea is to measure the relative positions of minutiae, in the same sort of way you might recognize a part of the sky by the relative positions of stars.

1.12.2 software Interfaces

In this project,the software interface needed are Oracle 9i,C#.Net(Visual studio) and an operating system windows xp.

1.12.3 Communication Interfaces

This software is a network based one. We need some other hardware components for connecting these software to a network.

1.12.4 Memory constraints

Memory constraints are related to the software project‘s memory management which tells the minimum memory required for running this software.

In the case of .net software projects, it needs a minimum 256Mb RAM for smooth running of software.

1.13Operations

The main operations in this software systems are

· Authentication.

· Encryption.

· Decryption.

· Printing the data and the report.

1.14 Product functions

Here the confidential data are encrypted using public key encryption method .Fingerprint authentication is used to login and decrypt the data. This system encrypts the data and only the authorized person can be able to view the data using their biometric features. The user use his/her private key to decrypt the data (cipher text) .These user can able to print the decrypted data. For the identification of fingerprints, PCA algorithm is used. This application more concern with the data security or data security is the main aim behind this application software. In this method, each user will be provided public key and private key .Using public key user encrypt his/her confidential data and after encryption the cipher text will be send to another(receiver) user. For data encryption, RSA algorithm is used ,Here we use 1024 bit RSA encryption.

We may need to encode independent pieces of data (be they files, communications across a network etc), and we might want them to be encoded differently so that just because Person A can decode File A' with our system doesn't necessarily mean that Person B can decode File B' with our system.

1.15 User characteristics

For operating this software, the educational level ,technical skill and technical experience of user is not important.

1.16 Specific Requirements

CHAPTER 2

DESIGN SPECIFICATION

2.1 Introduction

2.1.1 Design Overview

Design is a fundamental human activity. Design provides a structure to any artifact. It decomposes a system into parts, assigns responsibilities to each part, and ensures that the parts fit together to achieve the global goals of the system.

In the case of software, design is the activity that acts as a bridge between requirements and implementation of software. Once we have determined the need for a system and we have decided on its desirable qualities, including the interface it provides for interaction with the external world, we proceed to design that system. The first result of the design activity is an architectural design that shows the major parts of the system and how they fit together and cooperate.

The output of the design activity is software design. A software design is defined as a decomposition of modules-a description of what each module is intended to do and of the relationship among the modules. Often software architecture is prior to a software design and it guides the development of the design

2.1.2Purpose

The purpose of our software project is to design a Fingerprint based Data encryption system to transfer encrypted data through a network ie ,data security is the main aim behind this application software . There are several benefits of doing this. First, a user can send their confidential data to another user using their biometric features. This system is developed for the communication of persons working in an organization in secure manner with the help of their finger print. The interaction is provided through a client server application. Users in the system are classified into different levels, based on the categories they have given different privileges by the super user. The members in an organization can transfer files among themselves. The files are accessible only to authorized persons.

2.1.3 Scope

This software includes the following features

· A secure login and registration system using fingerprint authentication, which allows only the users in that organization to access the system’s.

· Transfer the confidential data to other users ,and the end user can print the delivered data.

· Here RSA algorithm is used for data encryption .

2.2 Database design

A data base is a collection of logically related records. The main objective of data base is to provide effective auxiliary storage without any application and contribute to the overall efficiency of the computer program components of the whole system.

The organization of data in the database aims to achieve the following objectives

· controlled redundancy

· ease of learning in use

· data independence

· more information in low cost

· accuracy and integrity

· recovery form failure

· privacy and security

· performance

The normalization process takes a relation schema through a series of tests to certify whether it satisfies a certain normal form. The process, which proceeds in a top-down fashion by evaluating each relation against the criteria for normal forms and decomposing relations as necessary, can thus be considered as relational design by analysis. There are mainly three normal forms: first, second, and third normal form. All these normal forms are based on a single analytical tool: the functional dependencies among the attributes of a relation.

Normalization of data can be considered a process of analyzing the given relation schemas based on their FDs and primary keys to achieve the desirable properties of,

· Minimizing redundancy

· Minimizing the insertion, deletion, and update anomalies.

Unsatisfactory relation schemas that do not meet the normal form tests are decomposed into smaller relation schemas that meet the tests and hence the desirable properties.

The normal form of a relation refers to the highest normal form condition that it meets, and hence indicates the degree to which it has been normalized.

First normal form

First normal form (1NF) states that the domain of an attribute must include only atomic values and that the value of any attribute in a tuple must be a single value from the domain of that attribute. Hence, 1NF disallows relations within relations or relations as attribute values within tuples. The only attribute values permitted by 1NF are single atomic values.

Second normal form

Second normal form (2NF) is based on the concept of full functional dependency. A functional dependency is a full functional dependency if removal of any attribute does not hold the dependency any more.

A relation schema is in 2NF if every nonprime attribute in relation is fully functionally dependent on the primary key of that relation.

Third normal form

Third normal form is based on the concept of transitive dependency. A relation schema R is in 3NF if it satisfies 2NF and no nonprime attribute is transitively dependent on the primary key.

Our project is fully normalized up to second normal form where each key is fully depending on the primary key. The database of our project is designed using Oracle 10g and it comprise of 3 tables.

The design should be done in a way the information stored in the database can retrieve quickly whenever needed. It Provide a high-level overview of how the functionality and responsibilities of the system were partitioned and then assigned to subsystems or components.

In this ,data are encrypted using public key encryption method .Fingerprint authentication is used to login and encrypt/decrypt the data. This system encrypts the data and only the authorized person can be able to view the data using their biometric features. For the identification of fingerprints, the fingerprint reader is used. This application more concern with the data security or data security is the main aim behind this application software. In this method, each user will be provided public key and private key .Using public key user encrypt his/her confidential data and after encryption the cipher text will be send to another(receiver) user. For data encryption, RSA algorithm is used ,Here we use 1024 bit RSA encryption .A RSA key length of 1024 bits is sufficient for many medium-security purposes such as web site logins etc.. Its main application areas includes the Police department,Court,Secret service departments, Industries , Educational Institutions etc..

The main functionalities used in this project are:

· Fingerprint Authentication.

· Data Encryption.

· Transferring the encrypted data through a network.

· Data Decryption (the encrypted data is decrypted and the authorized user can access it).

· To obtain the view of decrypted data to the user (eg: employee data).

· User can print the reports (e.g.: data).

The main purpose Here is to gain a general understanding of how and why the system was decomposed, and How the individual parts work together to provide the desired functionality. At the topmost Level, describe the major responsibilities that the software must undertake.

Hardware Architecture

Here the database is installed in the server and we access the data or send the encrypted data through a local area network connection.

Internal Communications Architecture

By using this software we can easily identify the other systems in the network and also can send encrypted data to any other user through a LAN.

Software Architecture

Which includes the all software systems that support the fingerprint based encryption for confidentiality and authentication system.

2.2.1 TABLES

There are 3 table’s in this project

1: Registration: This table used for registering a new user ,the attributes are userid,username,name,address,gender,dob,contactno:,designation,department,fingerprint id.

2: Login: This table used for authentication of user,ie a username and fingerprint of that user is the login name and password.

3: Message: After encrypting a file(.txt,.rtf,.doc etc) the sender keeps the data path in the data table,so the receiver can identify the location of encrypted data and easily decrypt it using his/her fingerprint.

2.3 Data Flow Diagram:

As the name suggests DFD is a representation of the data flow within the system. It includes processes, data stores and external interfaces to the system. External interfaces may be treated as external entities. DFD’s can by explode to sub-processes. Any two entities/data stores must be connected to each other by some process. The processes cannot be directly connected to each other. The following are the four major components of the DFD:

· Process

· External Entity

· Data Store

· Connector

The DFD is also known as the bubble chart. It is a simple graphical formalism that can be used to represent a system in terms of the input data to the system, various processing carried out in these data and the output data generated by the system. The main reason why this DFD technique is so popular is probably because of the facts that DFD is very simple formalism. It is simple to understand and use. A DFD model uses a very limited number of primitive symbols to represent the functions performed by a system and the data flow among these systems. Starting with a set of high-level functions that a system performance of DFD model in hierarchically it represents various sub functions. The Data Flow Diagramming technique also follows a simple a simple set of intuitive concepts and rules.

2.4 Entity-Relationship Diagram (ERD)

The Entity Relationship Diagram (also known as an ERD or E-R diagram) is a network model that describes the stored data layout of a system at a high level of abstraction. The ERD should represent the relationships between all the entities. Any two entities must be connected to each other by some relationship set and type of relationship should also be specified.

Components of an ERD

There are two major components of an ERD:

Entity:

It is defined as any object about which information is collected. It has different attributes which describe it. It should be represented by a regular box as shown below:

Relationships:

Entities are connected to one another by relationships. a relationship represents a set of connections between entities and represent by a diamond.

A relationship is a two-directional significant association.

There are three types of relationships

 One-to-one relationships

 One-to-many relationships

 Many-to-many relationships

2.6 Process Design

2.6.1 Input Design

Input design is the process of converting the user originated inputs to a computer based format. The goal of designing input data is to make the automation is easy and free from errors. The design for handling input specifies how data are accepted for computer processing. Input design is of overall system design that careful attention and if includes specifying the means by which action are taken. a system user interaction through a work station must be able to tell the system whether to accept input produce a report or end processing. The collection of input data is considered to be the most expensive part of the system design. Since the inputs have to be planned in such a manner so as to get the relevant information extreme care is taken to obtain the information .if the data going into the system is incorrect then the processing and outputs will magnify these errors.

2.6.2 Output design

A quality output is one which meets the requirement of the end user and presents the information clearly .In any system, the results of processing are given to the users through the outputs.In the output design it is determined how the information is to be displayed for immediate need.

Output design should improve the relationship of the system with the user and help in decision –making. The objective of the output design is to define the format of all printed documents and of screens that will be produces by the system. The output has been designed as per the needs of the institution .The suggestions of the users are also taken into consideration while designing the layouts and the fields that are to be included in the project.

2.7 USER INTERFACE DESIGN

1: Login

In this Login window ,we give our username and our fingerprint id as input,in the case of the administrator he gives username and password as input.For each new registration the username and fingerprint id stored to login table.

Fig 2.4

2:Registration

In the first text box accept the user id which is a number,the second textbox accept the full name of the user, then the next textbox for the username,the username of that particular user is provided by the administrator.the next textbox for input the address of the user.the radiobutton is used to select the gender of the user(Female or Male).the combobox is used to select the date of birth of the user.then enter the contact number ,designation and department of the user ,atlast scan the finger using fingerprint scanner,and then get a key in that text box usually in the number format.

Fig 2.5

3:Encryption form

For encrypting a data, use the upload option and then upload users data .After uploading if there is any correction ,user can select the view option and then at the left side of the window the user can edit the data and also save the new data.then select the encryption option and create the encrypted data. Now select the receivers name from the list of all users

Here user id is considered as the primary key.then send the data.

Fig 2.6

4:User details

From this window the administer can list the all users (eg:employee) ,delete the selected user and also search a particular user by using his user id.

Fig 2.7

5:Decryption form

In the decryption form ,the user first select the data from the left side after that select the decryption option and then user can see the decrypted data by selecting view option.then the user can save or print the data.

Fig 2.8

CHAPTER 4

TESTING

4.1 Introduction

The chapter testing describes various testing methodologies which are adapted and detailed view of test data’s within each database. During testing of a program to be tested is executed with a set of test data and the output of the program for test data is evaluated.

4.2 Unit Testing

Unit Testing is a procedure used to validate that individual units of source code are working properly. A unit is the smallest testable part of an application. In procedural programming a unit may be an individual program, function, procedure, etc., while in object-oriented programming, the smallest unit is a method; which may belong to a base/super class, abstract class or derived/child class. Ideally, each test case is independent from the others; mock objects and test harnesses can be used to assist testing a module in isolation. Unit testing is typically done by developers and not by Software testers or end-users

4.3 Integration Testing

Integration testing is the phase of software testing in which individual software modules are combined and tested as a group. It follows unit testing and precedes system testing. Integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing. The purpose of integration testing is to verify functional, performance and reliability requirements placed on major design items.

The following are the types of Integration Testing

4.3.1 TOP DOWN INTEGRATION

This method is an incremental approach to the construction of program structure. Modules are integrated by moving downward through the control hierarchy, beginning with the main program module. The module subordinates to the main program module are incorporated into the structure in either a depth first or breadth

4.3.2 BOTTOM-UP INTEGRATION

This method begins the construction and testing with the modules at the lowest level in the program structure. Since the modules are integrated from the bottom up, processing required for modules subordinate to a given level is always available and the need for stubs is eliminated. The bottom up integration strategy may be implemented with the following steps:

The low-level modules are combined into clusters into clusters that perform a specific Software sub-function.

A driver (i.e.) the control program for testing is written to coordinate test case input and output.

The cluster is tested.

Drivers are removed and clusters are combined moving upward In the program structure

4.4 Validation and testing

Software validation is achieved through a series of tests that demonstrate conformity with requirements. Validation succeeds when software functions in a manner that can be reasonably expected by the end user. Testing is necessary for the success of the system. During testing of a program to be tested is executed with a set of test data and the output of the program for test data is evaluated to determine if the programs are performing as expected.

First the application goes through a phase often referred as alpha testing in which the errors and failures based on simulated user requirements are verified and studied. The modified software is then subjected to phase two called beta testing in the actual user’s site or live environment. After a scheduled time, failures and errors are documented for final correction and enhancements are made before the package is released

In our project, validation and checks have been done in order to ensure that the developed system is performing up to its expectation. Validations have been done in the area of login sections and registration sections. In registration forms, certain rules have been set like no field is left blank. In this way each field in the registration form are checked, checking for user name availability and reporting status. In the login pages appropriate messages are displayed when a user provides an invalid response.

4.5 System Testing

System testing of software or hardware is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic.

It is the process of executing the program with the intent of finding errors Testing cannot show the absence of defects; it can only show that software errors are present.

Test Type

· Functionality testing.

· Usability testing.

· Interface testing

· Compatibility testing.

· Functionality Testing

Tested forms in all pages:

Forms are the integral part. Firstly checked all the validations on each field like user name and password,checking whether all mandatory fields are filled and so on. Checked by providing wrong inputs to the fields in the forms and found they are responding appropriately. Wrong input include like proving an invalid user name or password.

Checks have been made to ensure whether the database functions are working. Like when a new user registers with the site there is database query regarding this. So, these queries are tested by looking into the actual database whether all entries have been affected to the database. If this is not the case, query is checked and rectified. Database checking was positive.

· Interface Testing:

The main interfaces are: client application interface and database interface. In this project, ORACLE 9i is used. ORACLE 9i should hold all the C# files which will be interacting with the application logic in the C# .NET. All these interactions between has been checked and found to be working properly. Errors are also handled properly.

CHAPTER 5

IMPLEMENTATION

5.1 Introduction

Implementation is a process of converting a new system into an operational one. The designed system is converted into an operational one using a suitable programming language. Implementation includes all those activities that take place to convert an old system into a new one. Proper implementation is necessary to provide a reliable system to meet organizational requirement.

5.2Implementation plan:

Our project is client server oriented ,so we need a client server network. Administrator and users have computers with minimum requirements, and a fingerprint reader to read the finger print on each system’s. So it can be very easily established in a firm or companies in which there use group of computers having interconnected network. A user/administrator can use the software with his or her basic knowledge.

Administrator can add user by simply entering his or her details into the registration form and add his or her fingerprint using the fingerprint module in his or her presence. After registration the registered users can explore user window.

Our software provide full security on the data send or receive, so user can send data at any time using his or her fingerprint for authentication. The administrator can monitor all user’s activity.

In the implementation plan the requirements for implementing the project is determined and also tested to confirm the effectiveness while implementing the project design into the source code. The main goal of the implementation plan is the development of source code that is easy to read and understand. The implementation plan will help the project to proceed with the available resources. Once the implementation plan is over the source code can be developed easily because it will provide a clear idea about the project. The implementation of the proposed system is achieved via to the C#.net platform as front end and Oracle 9i as backend. Front end consist of language tools and mechanisms for manipulating the backend.

5.3 Conclusion

Implementation describes about the whole activities necessary to provide a reliable system to meet the necessary requirement.
