Security Protocols and Encryption
Voise prioritizes security at every level of the system, from initial voiceprint creation to real-time authentication. Several key technologies ensure that user data remains private and secure:
Cryptographic Security:
Voiceprint Encryption:
The user’s voiceprint is converted into a cryptographic hash using SHA-256 encryption, a widely trusted cryptographic algorithm. This ensures that the voiceprint is not only secure but also irreversible—no one, not even Voise, can reverse-engineer the voiceprint to reconstruct the user’s original voice.
Blockchain-Based Storage:
The voiceprint hash is stored on the Ethereum blockchain, leveraging its decentralized and immutable nature to ensure data integrity. This makes it impossible for a single entity to alter or tamper with the stored data, providing additional layers of trust and security.
Zero-Knowledge Proofs:
Voise implements zero-knowledge proof (ZKP) protocols during authentication. This allows the system to verify the user’s identity without actually revealing the underlying voiceprint. The system confirms a match between the real-time voice input and the stored voiceprint hash without exposing sensitive information.
Privacy Protection:
No Raw Voice Storage: Voise does not store or share raw voice recordings. Only the encrypted voiceprint hash is kept, significantly reducing the risk of biometric data being stolen or misused.
Anonymization: The system uses anonymization techniques during voiceprint creation to ensure that even if the encrypted hash were to be compromised, it would be meaningless without the corresponding cryptographic key.
