An Improved Joint Fingerprinting and Decryption Content Security Protection Scheme for Visual Media
Only combining encryption with fingerprinting together can provide comprehensive content security protection for visual media. Joint fingerprinting and decryption (JFD) framework solves encryption and fingerprinting simultaneously and has high efficiency, but several problems still remain to be tackled in JFD, including poor encryption security, severe fingerprinted image distortion, etc. An improved JFD scheme is presented in the paper, where a new encryption strategy based on selective content encryption is put forward to enhance security, and a new method for choosing fingerprint embedding area by structural distortion is proposed to reduce fingerprint’s influence to image quality. The experiment results show our scheme’s effectiveness.
