Abstract:

Identifying the camera with which a video has been taken can under the right circumstances be done using the Photo Response Non-Uniformity（PRNU）, which acts as a unique fingerprint for cameras. In this paper we use the wavelet filter from Lukás et al[1] to extract the PRNU pattern from a video file that is re-encoded using the Advanced Video Codec. Different video resolutions and encoding settings were used to investigate the influence of this re-encode on the PRNU pattern. It is shown that even after a video is re-encoded it is still possible to link some videos to their original camera.

Key words: photo response non-uniformity, original camera, re-encode, wavelet filter
