SeVoAuth: Secure Voiceprint Authentication With Hash-Based Feature Transformation

Summary

SeVoAuth is a cloud-based Voiceprint Authentication as a Service (VAaaS) system that stores a synthesized voiceprint rather than the user's real one. During each authentication session, it applies a hash function to transform the synthesized voiceprint's features and generate new verification targets. The authors report an average authentication accuracy of 99.47% and an average Precise Detection Rate (PDR) of 98.35% against various attacks.
