Abstract

The advent of social networks has made social media sharing in social network easier. However, it can also cause serious security and privacy problems, secure media sharing and traitor tracing issues have become critical and urgent. In this paper, a joint fingerprinting and encryption (JFE) scheme based on Game of Life (GF) and singular value decomposition (SVD) with the purpose of protecting content distribution in social networks. Firstly, the fingerprint code is produced using social network analysis. Secondly, fingerprints are embedded into the LL, HL and LH subbands. At last, GF and SVD are used to for confusion and diffusion respectively. The proposed method, to the best of our knowledge, is the first JFE method using GF and SVD in the compressed domain for security and privacy. The use of fingerprinting along with encryption can provide a double-layer of protection to media sharing in social network environment. Theory analysis and experimental results show the effectiveness of the proposed JFE scheme.
