| Abstract: | Digital fingerprinting embeds unique information in each distributed copy and can be used to protect multimedia from illegal redistribution. In video streaming applications, there are a large number of users and huge amount of data to transmit. Thus, given a multimedia fingerprinting system with the required robustness, it is essential to efficiently distribute fingerprinted copies without revealing the embedded fingerprints. In this paper, we propose a bandwidth efficient fingerprint multicast scheme that can be used with most spread spectrum embedding based multimedia fingerprinting systems, and analyze its bandwidth efficiency. We also propose a fingerprint drift compensation for the fingerprint multicast scheme to improve the quality of the reconstructed frames at the receiver's side without increasing the communication cost. | ||
