This paper introduces a near-lossless reversible system. It replaces sensitive RoIs (Regions of Interests) by their edges in order to protect privacy of people. Besides, the visual quality needed for security in real time is kept. The proposed system outperforms the state-of-the-art methods according to four criteria: near-lossless reversible, computation speed, usability and privacy protection. We prove the effectiveness of the proposed filter using face recognition algorithms on different images.
