Graphical Authentication: Justifications and Objectives
نویسندگان
چکیده
Password authentication has failed to address the compounding business requirement for increased security. Biometric authentication is beginning to address the need for tighter security, but it costs several orders of magnitude more than basic password implementations. Biometric authentication also possesses several shortcomings that inhibit its widespread adoption. In this paper we describe the trends in the literature before presenting the justifications and objectives for graphical authentication: a viable alternative to both biometrics and passwords. We also intend the paper to serve as a prelude to forthcoming implementation and validation research.
