PASSWORD
oThe most commonly used form of User authenticationoVarious types of passwordsoStrength of passwordoEvolution of password technique
TYPES OF GRAPHICAL PASSWORDPass faces Pass Points DAS (Draw-A-Secret)
oPass faces• Faces are used as a graphical portfolio• Preference could be a limitationoPass Points• Use “a sequence of clicks” as a shared secret• There are hot spots oDAS(Draw A Secret)• Use “a sequence of clicks” as a shared secret• There are hot spots

Proposed System
ADVANCEMENT IN GRAPHICAL PASSWORDoUse of QR code instead of textual user nameoUsing password encryption techniqueoSending alert message to user if attacker attempts to login
CURRENT SCOPE
oLocking folder’s
oLock application for smart phones
oSecuring Hard Disk
FUTURE SCOPE
oATM Login SystemoWeb based login
DETAILS OF SOFTWARE REQUIREMENTSoNetBeans IDE 8.02oJava 1.8oSql server for database connectivity
DETAILS OF HARDWARE REQUIREMENTSoMinimum hard disk space required 500GBoMinimum RAM required 2GBoProcessor Intel Core i3oOperating system Windows 7
Advantageso Easy to remembero Reduced shoulder surfing attackso Alert message on wrong attempto Use of QR codes
Disadvantageso Slightly time consuming
DO’S AND DON’TS FOR SECURED PASSWORD
Do’soUse easy to remember textual based color codesoEnter minimum 5 characters and maximum of 8 charactersoInclude special Characters to improve complexityDon'tsoDo not insert password which are easy to guess
CONCLUSIONoTextual based color passwords are an alternative to Picture password.
oIt satisfies both conflicting requirements i.e. it is easy to remember & it is hard to guess.
oBy the solution of the shoulder surfing problem, it becomes more secure & easier password scheme.
oBy implementing encryption algorithms and hash algorithms for storing and retrieving points, one can achieve more security
oTextual based color password is still immature, more research is required in this field.
