Parallel joint fingerprinting and encryption for social multimedia sharing based on game of life

Abstract

The advent of online social network and mobile multimedia communication has made content sharing in social network easier and more efficient. It is very important to combine fingerprinting and encryption for social multimedia content protection. In this paper, a parallel JFE (joint fingerprinting and encryption) framework is proposed. Firstly, the multi-level social fingerprint code is produced using social network analysis, and followed by TSH (tree structure harr) wavelet decomposition for multimedia content. And then, fingerprints are embedded into all the LL, HL and LH subbands parallelly. At last, GoL(Game of Life) are used to for confusion for wavelet coefficients parallelly. The proposed parallel JFE method, to the best of our knowledge, is the first JFE method using GoL in the TSH wavelet domain for security and privacy. Theory analysis and experimental results demonstrate the effectiveness of the proposed JFE scheme.
