Secure Architecture and Protocols for Robust Perceptual Hashing

This paper proposes a new architecture for the secure application of robust perceptual hashing. Protocols based on architecture of four parties are designed to ensure that no party can get the knowledge that may break the security of the hashing. A commutative hashing and encryption method that can generate multi-media hash on encryption domain is proposed to further resolve the privacy and security issues in the application of robust perceptual hashing.
