Abstract:
Fingerprint techniques have a significant advantage in respect of watermarking: a fingerprint can be extracted in each moment of the lifetime of a multimedia content. This aspect is fundamental to solve the problem of copy detection mainly because many copies can be available in huge amount of data in circulation and because each copy can be attacked in several ways (compression, re-encoding, text-overlay, etc.). In this paper the problem of copy detection is studied and tested from two different point of views: content based and identification approaches. The results show that the proposed system is quite robust to some copy modifications and most of all show that the overall results depend on the evaluation method used for testing.
