摘要：In today world security means everything for people specially for web application because each andevery day people getting attracted to internet and it's application. Authentication is very important thing in securitythere is already so many technique used for authentication. Traditionally there was text password are demanding then itget replace with new techniques like Image password, Biometrics password, graphical password, map based passwordand further more location password from where GeoPass technique came at starting the performance of GeoPass wasvery good as per the memorability concern because previous techniques was efficient as per the security ,but makingpassword more secure lead the problem of complexity of remembering password. After some time some problem cameinto light in GeoPass as GeoPass technique suggest to select a location which should be rememberable for user but itseen, many users select any location they found interesting on map which led to guessing attack on system. So itmotivate to make system more secure as well as memorable. In the Proposed scheme at initial level the coordinatebased location of selected city is provided with extension of mnemonics password. The mnemonic password isgenerated for selected location by using word mnemonics technique in which first letter from each location selectedand make a mnemonics from selected location and substring in sequence of location selected along with annotationattributes on digital map provided for user. The result generated on basis of different threat model for existing andproposed and then compare on basis of ratio of unsuccessful attempt of login of unauthenticated user. In whichproposed scheme security ratio is high for different attack models from which it conclude, a proposed solution schemesecurity level increase from threat by giving contribution of mnemonics password in existing scheme to makeauthentication more memorable and secure against online guessing attack.
