Since the mid Nineteen Nineties, information hiding has been proposed as an allowing know-how for securing multimedia conversation, and is now utilized in quite a few purposes together with broadcast tracking, motion picture fingerprinting, steganography, video indexing and retrieval, and picture authentication. information hiding and cryptographic concepts are frequently mixed to enrich one another, hence triggering the advance of a brand new learn box of multimedia safety. in addition to, similar disciplines, steganalysis and knowledge forensics, are more and more attracting researchers and changing into one other new learn box of multimedia safeguard. This magazine, LNCS Transactions on facts Hiding and Multimedia safeguard, goals to be a discussion board for all researchers in those rising fields, publishing either unique and archival examine effects.
This factor incorporates a targeted part on forensic photo research for crime prevention together with papers. the extra 4 papers take care of collusion-resistant fingerprinting structures, part correlation established snapshot matching in scrambled area, and visible cryptography.

They include codeword design, shifted spreading, pilot-based channel estimation, receiver design, etc. Furthermore, we present results on capacity, throughput, and distortion of a colluded media ﬁle. Finally, we will mention some open research problems. Keywords: multi-access interference, time-varying collusion attacks, human perceptual system, multimedia distortion, advanced detection, collusion-resistant ﬁngerprinting. 1 Introduction Fingerprinting technology provides a solution to traitor tracing in multimedia distribution over the Internet.
The number of colluders and the coherent time determine the quality of a colluded media ﬁle. This relationship has been investigated for image, audio, and video by the authors. A qualitative characterization of the tradeoﬀ between the colluder detection performance and colluded image quality is depicted in Fig. 6. That is, when the coherent time is shorter, the colluder detection performance becomes poorer while the distortion of the colluded media becomes higher. As a result, there is a bound on the maximum colluder number and the minimum coherent time due to the quality consideration.
