We propose a reversible privacy protection technique for surveillance camera which enables controlling quantitative scramble degree and file size increase. Our proposed technique combines scrambling method based on square value calculated from target image quality and embedding method using histogram manipulation for reconstruction information in the image compression process, and these are performed in every DCT $8times8$ block divided into scrambling area and data hiding area respectively. We confirmed the validity of our technique by scramble degree control experiment with two types of images having different number of people. |
