Face biometrics are unique, natural, and invariant throughout one’s life cycle. Therefore, face recognition, as an identity authentication method, is much more convenient than traditional techniques. However, it is susceptible to forgery attacks such as pictures, videos, and masks. The leakage or tampering of invariant biometrics will induce irreversible losses. The solution to secure face recognition proposed in this study uses a special module of secure face acquisition for liveness detection. A special secret key in the module is applied to encrypting every face image and signing the sensitive information. Additionally, multiple steps in the recognition process guarantees the security of face biometrics.
