This paper presents a robust image hashing algorithm that exploits low-rank decomposition and path integral local binary pattern (pi-LBP), referred to LRPL hashing. The proposed algorithm generates a compact binary sequence from a low-rank component of the normalized image as the hash code. Considering the excellent texture structure description ab...

Robustness and discriminability are the two most important features of perceptual image hashing (PIH) schemes. In order to achieve a good balance between perceptual robustness and discriminability, a novel PIH algorithm is proposed by combining latent low-rank representation (LLRR) and rotation invariant uniform local binary patterns (RiuLBP). LLRR...

A lot of attention has been paid to anonymity due to the users' privacy protection. While peer-topeer (P2P) networks need anonymity capacity, the authority also requires partner traceability to prevent anonymous abuse. So there is a challenge to harmonize the dilemma between the anonymity and authentication in P2P networks. Few P2P protocol provide...
