Video copy detection based on source device characteristics: A complementary approach to contentbased methods

We introduce a new video copy detection scheme to com-plement existing content-based techniques. The idea of our scheme is based on the fact that visual media possess unique characteristics that can be used to link a media to its source. Proposed scheme attempts to detect duplicate and modified copies of a video primarily based on peculiarities of imaging sensors rather than content characteristics only. We demon-strate the viability of our scheme by both analyzing its ro-bustness against common video processing operations and evaluating its performance on real world data. Results show that proposed scheme is very effective and suitable for video copy detection application
