A Content Providing System with Privacy Protection

With the development of Internet technology, people can conveniently exchange and share image/video without the limit of time and space. In one image/video, some parts can be open to the public and some cannot or only can be open to specific people because of privacy issue. How to protect privacy information in the image/video has become more and more important. This paper proposes a content (image/video) providing system with privacy protection, which is supposed to make the most of the data and provide varying degrees of privacy/security. We apply fuzzy homomorphic encryption to protect privacy-sensitive area and realize hierarchical access to the data based on Chinese Remainder Theorem. Finally, we conduct the simulation experiments and evaluate the system feasibility.
