Fingerprint multicast in secure video streaming

Abstract

Abstract-Digital fingerprinting is an emerging technology to protect multimedia content from illegal redistribution, where each distributed copy is labeled with unique identification information. In video streaming, huge amount of data have to be transmitted to a large number of users under stringent latency constraints, so the bandwidth-efficient distribution of uniquely fingerprinted copies is crucial. This paper investigates the secure multicast of anticollusion fingerprinted video in streaming applications and analyzes their performance. We first propose a general fingerprint multicast scheme that can be used with most spread spectrum embedding-based multimedia fingerprinting systems. To further improve the bandwidth efficiency, we explore the special structure of the fingerprint design and propose a joint fingerprint design and distribution scheme. From our simulations, the two proposed schemes can reduce the bandwidth requirement by 48% to 87%, depending on the number of users, the characteristics of video sequences, and the network and computation constraints. We also show that under the constraint that all colluders have the same probability of detection, the embedded fingerprints in the two schemes have approximately the same collusion resistance. Finally, we propose a fingerprint drift compensation scheme to improve the quality of the reconstructed sequences at the decoder's side without introducing extra communication overhead.

Fragile watermarking based on incomplete cryptography for copyright protection

“…Multimedia fingerprinting techniques (Boneh and Shaw 1998;Trappe et al 2003;Wu et al 2003;Zhao and Liu 2006) are developed to deal with the illegal redistribution problem. Before transmitting digital content from the content producer to the legal users, a digital fingerprint should have already been embedded into the content.…”

A New Framework for Encryption and Authentication of Multimedia Data

“…Therefore, proper coding techniques can be used to generate fingerprint such that it is resistant against collusion attacks. The most popular coding techniques are orthogonal fingerprinting and coded fingerprinting using BIBD techniques [12][13][14].…”

“…The joint fingerprinting and decryption (JFD) technique can fulfill this requirement. Since, the JFD technique provides lesser system complexity, better real time system performance and is resistant against various types of collusion attacks [12][13][14], it is the most promising technique for multimedia authentication.…”

A Multi-Key Pirate Decoder Against Traitor Tracing Schemes

“…Generally, three major post-tracing methods are digital fingerprinting, black-box confirmation and traitor tracing. Digital fingerprinting technology (e.g., [10][11][12][13]) embeds a unique label into the digital content so as to identify the illegal distributor. Since this technology is tightly related to watermarking, and it is orthogonal to the objective of this paper.…”
