To use peer-to-peer network permits to reduce bandwidth network cost but the security of these networks is not efficient: malicious peers can corrupt the system by inserting some unwanted content directly in video. In opposite of existing security system we propose a content oriented protection: any movie taken on this system can be verify along the download using only one required key. In each frame we insert a hidden message containing representation of 3 frames : the preceding and the following ones and a random one (obtain by a random permutation). It is then impossible to corrupt the peer-to-peer video sharing network, as long as the message may be recognize in the video. We present a color steganographic algorithm and show that it is able to hide without visual losses all required information. %G English %L ujm-00366599 %U https://ujm.hal.science/ujm-00366599 %~ UNIV-ST-ETIENNE %~ IOGS %~ CNRS %~ LAHC %~ PARISTECH %~ UDL
