Abstract

A Graphical Cryptographic Verification System that restores the static digital pictures naturally used in graphical password systems with personalized physical tokens, here in the form of digital pictures showed on a physical user-owned device such as a mobile phone. Users present these pictures to a scheme camera and then enter their password as a sequence of selections on live video of the token. Extremely distinctive optical characteristics are extracted from these selections and utilized as the password. We present three probability studies of examining its consistency, usability, and safety against surveillance. The consistency study Graphical Cryptographic Verification System demonstrates that image-feature based passwords are viable and suggests appropriate system thresholds password items should include a minimum of seven features, 40% of which must geometrically equal unique stored on an authentication server in order to be moderator equivalent. The usability study calculates task completion times and error rates, revealing these to be 7.5 s and 9%, broadly comparable with preceding graphical password systems that use static digital images. In the end, the safety study highlights Graphical Cryptographic Verification System conflict to observation attack three attackers are able to compromise a password using shoulder surfing, camera based observation, or malware. These results indicate that Graphical Cryptographic Verification System shows promise for safety while maintaining the usability of current graphical password schemes.
