A Secure Mobile Authentication Alternative to Biometrics
Mozhgan Azimpourkivi, Umut Topkara, Bogdan Cărbunar · 2017
Biometrics are widely used for authentication in consumer devices and business settings as they provide sufficiently strong security instant verification and convenience for users. However, biometrics are hard to keep secret, stolen biometrics pose lifelong security risks to users as they cannot be reset and re-issued, and transactions authenticated by biometrics across different systems are linkable and traceable back to the individual identity. In addition, their cost-benefit analysis does not include personal implications to users, who are least prepared for the imminent negative outcomes, and are not often given equally convenient alternative authentication options.
