SeVoAuth: Secure Voiceprint Authentication With Hash-Based Feature Transformation

SeVoAuth is a cloud-based voiceprint authentication system (a security method that recognizes users by their unique voice characteristics) designed to protect user privacy while defending against replay attacks (replaying a recorded voice), spoofing (faking a voice), and adversarial attacks (manipulating input to fool the system). The system stores a synthesized version of a user's voice in the cloud and uses hash functions (mathematical functions that transform data into fixed-size codes) to continuously change the verification targets during each login, making it difficult for attackers to reuse old voice recordings or tricks.
