Zero-Knowledge Proofs in Speaker Verification |
As blockchain technology continues to grow in popularity, decentralized finance (DeFi) attracted attention by everyday users. However, with the rise of DeFi comes significant security and privacy challenges, especially the risk of losing funds due to compromised private keys. Enhancing security with user-friendly authentication methods is essential to address these concerns. Voice authentication has the potential to provide an additional security layer for blockchain systems, but implementing it in DeFi environments without compromising decentralization and privacy is complex. Moreover, advances in deep learning and voice cloning introduce new risks for voice-based systems. In this talk, we introduce ZK Verify Voice Authentication, a novel solution that integrates zero-knowledge proofs (zk-SNARKs) to ensure privacy-preserving speaker verification for the XRP Ledger (XRPL). By using voice embeddings as digital signatures and storing only their hashes on the blockchain, our system allows users to prove their identity without revealing sensitive voice data. This approach strengthens security and privacy for DeFi participants while maintaining ease of use, offering a secure and accessible solution for the broader blockchain ecosystem. |
