In this paper we present a system for preserving the privacy of individuals in video sequences by obfuscation of facial appearance, so as to render recorded people unrecognizable.
Therefore we address the following two problems: automatic face detection and scrambling of face region. A multi-resolution access control scheme is used in order to decrease the visual quality of regions containing faces, according to the user access right. The proposed scrambling scheme is achieved by combining a self-VQ coding module and a bit masking algorithm.
