Unpredictable Password Generation using Graphical Authentication and Decentralized Encryption

Abstract

Abstract—Privacy is which data can be safely disclosed without leaking sensitive information. The objective of a knowledge based secure system is to select stronger passwords for the users and to provide them secret keys. In this paper, a multi-authority decentralized encryption scheme is proposed which provides secret keys without knowing the global identifier of the user. This scheme issues secret keys without any cooperation from the different authorities. Any authority is free to join or leave the system. Users can select passwords of higher strength using click-points. Persuasive technology is used for generating graphical passwords.
