Anonymous Fingerprinting with Robust QIM Watermarking Techniques
Fingerprinting is an essential tool to shun legal buyers of digital content from illegal redistribution. In fingerprinting schemes, the merchant embeds the buyer’s identity as a watermark into the content so that the merchant can retrieve the buyer’s identity when he encounters a redistributed copy. To prevent the merchant from dishonestly embedding the buyer’s identity multiple times, it is es...
متن کاملRobust Anonymous Fingerprinting
Fingerprinting is an essential tool to shun legal buyers of digital content from illegal redistribution. An efficient, anonymous fingerprinting scheme has been proposed by Kuribayashi and Tanaka to provide a secure and efficient protocol for both buyer and merchant [2]. However, the underlying watermarking scheme is based on basic quantization index modulation (QIM). Unfortunately, QIM watermar...

متن کاملMPEG-4 AVC stream watermarking by m -QIM techniques
The present paper is devoted to the MPEG-4 AVC (a.k.a. H.264) video stream protection by means of watermarking techniques. The embedding process is carried out in quantized index domain and relies on the m-QIM (m-arry Quantisation Index Modulation) principles. In order to cope with the MPEG-4 AVC peculiarities, the Watson’s perceptual model is reconsidered and discussed. The experimental result...
متن کاملMulti-symbol QIM video watermarking
This paper introduces the theoretical framework allowing for the binary quantization index modulation (QIM) embedding techniques to be extended towards multiple-symbol QIM (m-QIM, where m stands for the number of symbols on which the mark is encoded prior to its embedding). The underlying detection method is optimized with respect to the minimization of the average error probability, under the ...
