Since the mid Nineties, info hiding has been proposed as an allowing expertise for securing multimedia conversation, and is now utilized in numerous functions together with broadcast tracking, motion picture fingerprinting, steganography, video indexing and retrieval, and snapshot authentication. facts hiding and cryptographic strategies are frequently mixed to counterpoint one another, hence triggering the improvement of a brand new learn box of multimedia safeguard. along with, similar disciplines, steganalysis and information forensics, are more and more attracting researchers and turning into one other new learn box of multimedia defense. This magazine, LNCS Transactions on facts Hiding and Multimedia defense, goals to be a discussion board for all researchers in those rising fields, publishing either unique and archival study effects. The 7 papers incorporated during this factor take care of the subsequent subject matters: safety of electronic video clips, safe watermarking, tamper detection, and steganography.

The test was done from outside the WM-embedding system using a five-step process, as illustrated in Figure 6. 1. A visible sequence code pattern was overwritten into each frame image (see left image in Figure 7). 2. The frames were written onto a DVD-Video disc. A DVD player then sent the frames in an SDTV video signal to the test system. 3. The test system embedded an invisible WM into every frame and output them in an SDTV video signal to a monitoring PC in real time. 4. The monitoring PC captured the visibly and invisibly marked video data and encoded it (QVGA, MPEG1) using lossy compression and wrote it to a file at 1 Mbps.

The aim in case (a) was that the evaluators would not perceive any visual degradation in the videos shown with the prototype system. The aim in case (b), on the other hand, was that the level of disturbance in the videos would be as high as possible. Table 1 summarizes the evaluation conditions. 1 Standards for Subjective Evaluation Standards for subjective evaluations can be classified into two types: evaluations defined by the International Telecommunication Union Radio Communications Sector (ITU-R)  and those defined by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) .
