Abstract: An implementation of a technology, described herein, for facilitating watermarking of digital goods. At least one implementation, described herein, performs quantization watermarking based upon semi-global characteristics of multiple regions of the digital good. Such regions are permissively overlapping. The scope of the present invention is pointed out in the appending claims.

Abstract: A technology is described herein for the protection of rights in the content of a video sequence. In one example the technology embeds an information pattern in one or more regions of a video signal. A region includes a plurality of successive frames. The example does not embed the information pattern in one or more different regions which are interposed between the one or more regions. Further, in this example, for one or more regions, the information pattern is embedded into a frame of a region with a relative degree of intensity. One or more frames of that region have the patterns embedded therein which have a relative intensity that differs from the relative intensity of the pattern embedded in other frames of the region.

Abstract: An implementation of a technology is described herein for deriving robust non-local characteristics and quantizing such characteristics for blind watermarking of a digital good. This technology finds the proper balance between minimizing the probability of false alarms (i.e., detecting a non-existent watermark) and the probability of misses (i.e., failing to detect an existing watermark). The technology, described herein, performs quantization index modulation (QIM) based upon non-local characteristics of the digital good. Non-local characteristics may include statistics (e.g., averages, median) of a group of individual parts (e.g., pixels) of a digital good. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

Abstract: An implementation of a technology is described herein for recognizing the perceptual similarity of the content of digital goods. At least one implementation, described herein, introduces a new hashing technique. More particularly, this hashing technique produces hash values for digital goods that are proximally near each other, when the digital goods contain perceptually similar content. In other words, if the content of digital goods are perceptually similar, then their hash values are, likewise, similar. The hash values are proximally near each other. This is unlike conventional hashing techniques where the hash values of goods with perceptually similar content are far apart with high probability in some distance sense (e.g., Hamming). This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

Abstract: An implementation of a technology is described herein for the protection of rights in the content of a video sequence. This technology further generally relates to a technology facilitating embedding imperceptible, de-synchronization-resistant watermarks in video sequence and facilitating detecting such watermarks. These watermarks are resistant against unintentional and intentional modifications. In particular, the watermarks are resistant to de-synchronization. In addition, the watermarks are perceptually invisible. The watermarks are hidden in the video so that flicker is minimized or eliminated. More specifically, this technology hides a watermark (of portions thereof) over one or more regions of successive frames. Each region has a center defined by a hash value. A watermark (of portions thereof) is encoded into the region in a “plateau” manner. The mark (of portions thereof) is fully encoded in the frames surrounding the region's center, but trail off towards the edges of the region.

Abstract: An implementation of a technology is described herein for recognizing the audio content of digital signals. The technology determines one or more hash values for the original audio content of a digital signal. In one implementation described herein, audio content recognition facilitates identification of the original audio content and other audio content that is substantially perceptually same to the original audio content. In another implementation described herein, audio content recognition facilitates semantic categorization of such original content so that it may be grouped with other audio works in the same semantic category. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
