GRAPHICAL PASSWORD AUTHENTICATION SYSTEM (GPAS)

BRAIN STORMING FOR DESIGN ALTERNATIVES:A brain storming session was conducted among the users to identify the design alternatives and results were noted down.DESIGN ALTERNATIVES: Alphanumeric Graphical Biometric Card system Pattern locksCOMPARATIVE TABLE:The table below compares the different design alternatives on the basis of certain parameters:PARAMETERSALPHANUMERICGRAPHICALBIOMETRIC

SecurityLess secureModerate securityHighly secure

User friendlyLess user friendlyMore user friendlyModerately user friendly

Design complexityLess complexLess complexMore complex

Maintenance No maintenanceneededNo maintenance neededMaintenance required

Ease of remembranceEasy to forget over long periodsEasily recallableRemembrance is not required

Additional Hardware Not requiredNot requiredRequired

Based on the above comparison we choose the graphical method of designing the password authentication system.The below reasons favor the GPAS: Graphical passwords are easy to recall They are more secure than the frequently used alphanumeric type It is feasible Less complexity in design and requires no additional hardwareDESIGN REQUIREMENTS FOR GPAS:HARDWARE USED:UTLPKITSOFTWARE USED:UBUNTU OSECLIPSE IDEPROGRAMMING LANGUAGE:CDETAILED DESIGN:The LOGIN module: To implement the login module featuring the entry of user name and password a GLCD on the kit is used.CLCD on the UTLP kit displays instructions for the user to proceed.

CONCLUSION:Based on the research done to study the difficulty of cracking graphical passwords it is found that there are no reports of real cases of breaking graphical passwords. Thus this system is proven to be efficient to be used.REFERENCES:The International journal of science & technolodge (www.theijst.com)Student sample solution:Anonymous
