  title={Homomorphic Encryption for Speaker Recognition: Protection of Biometric Templates and Vendor Model Parameters},
  author={Andreas Nautsch and Sergey Isadskiy and Jascha Kolberg and Marta Gomez-Barrero and Christoph Busch},
Data privacy is crucial when dealing with biometric data. Accounting for the latest European data privacy regulation and payment service directive, biometric template protection is essential for any commercial application. Ensuring unlinkability across biometric service operators, irreversibility of leaked encrypted templates, and renewability of e.g., voice models following the i-vector paradigm, biometric voice-based systems are prepared for the latest EU data privacy legislation. Employing…
