Abstract :
This paper presents a speaker identification using voice-based cryptography for mobile VoIP secure voice communication system. The cryptographic public key is generated from the user´s voice and used to encrypt the transferred voice data over IP networks. The voice fingerprint from the received voice data is decrypted for the speaker identification based on Bayesian information criterion and Mahalanobis distance.
