Voice Encrypted Recognition Authentication - VERA

Abstract

We propose VERA - an authentication scheme where sensitive data on mobile phones can be secured or whereby services can be locked by the user's voice. Our algorithm takes use of acoustic fingerprints to identify the personalized voice. The security of the algorithm depends on the discrete logarithm problem in ZN where N is a safe prime. Further we evaluate two practical examples on Android devices where our scheme is used: First the encryption of any data(set). Second locking a mobile phone. Voice is the basic for both of the fields.
