Natural Language Watermarking Using Semantic Substitution for Chinese Textd for embedding watermark in the text that is as successful as the frequency-domain methods have been for image and audio. The novel method embeds the watermark in original text, creating ciphertext, which preserves the meaning of the original text via various semantic replacements.

Use of Motion Estimation to Improve Video Watermarking for MPEG Encodersnd that, for the same picture quality after MPEG encoding and decoding, 30% more watermarks can be embedded than with the previous method. This new method would be most effective when implemented in MPEG encoders, which already have the necessary motion estimation functions.

0302-9743 earance in the academic community in the early 1990s, great progress has been made in understanding both the capabilities and the weaknesses of digital watermarking. On the theoretical side, we all are now well aware of the fact that digital waterma- ing is best viewed as a form of communication usi

Proctitis and Other Rectal Complaints pattern can increase the resilience of a segmented watermark in the presence of cropping attacks. In this paper, we consider performance measures for embedding patterns and compare the performance of several proposed embedding patterns using these measures.

Antonio Volpi,Lawrence Stanberryvided. This approximation has its roots in a Fourier series expansion of the aliased pdf’s that is introduced here. Finally, the case of general additive attacks is studied, showing that for the scalar case with equiprobable (and possibly infinite) symbols, Gaussian noise does not minimize capacity.
