The usage of video surveillance systems increases more and more every year and protecting people privacy becomes a serious concern. In this paper, we present ASePPI, an Adaptive Scrambling enabling Privacy Protection and Intelligibility. We integrate our process within the H.264 codec. The proposed approach automatically adapts the level of protection by modifying the DC coefficient according to the resolution of the region of interest. We encrypt and hide the original DCT coefficients in the AC coefficients. Compared to existing methods, our framework provides a better trade-off between the privacy protection and the visibility of the scene for monitoring. Moreover, the impact on the compressed stream is negligible.
