    摘要： Methods and systems for quantization and data embedding are described. In at least some embodiments, a transform is applied on an image that is to be watermarked and statistics associated with the image are computed. The computed statistics are quantized using a symmetric lattice, and a watermark is computed using the lattice quantized statistics. The watermark is then inserted into the image.

    摘要： An implementation is described herein facilitates certification of goods and/or identifications of the source of such goods. At least one implementation, described herein, embeds a watermark into a relatively small amount of data in a deterministic manner. At least one implementation, described herein, generates an authentication transformation matrix based, at least in part, upon an authentication watermark and a pre-defined humanly perceptible authentication pattern (e.g., image, audio). With this implementation, it obtains subject goods that may have the authentication watermark embedded therein. It generates a humanly perceptible resultant pattern (e.g., image, audio) based, at least in part, upon the watermark detected in subject goods and the transformation matrix. If the detected watermark is the authentication watermark, then the resultant pattern and the pre-defined authentication pattern will match (or nearly so). At least one implementation, described herein, hides a secret key around the periphery of watermarked goods. 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.

    摘要： 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.

    摘要： An implementation of a technology is described herein for recognizing the content of digital signals. The technology determines one or more hash values for the original content of a digital signal. In one implementation described herein, content recognition facilitates identification of the original audio content and other audio content that is substantially perceptually same to the original 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.
