摘要： Systems and methods are described that apply a watermark to data, such as data representing an image. In one implementation, the complexity of the image is measured. A quantization step size is calculated, based in part on the measured complexity of the image. A watermark or message is embedded into the image using the quantization step sizes derived for each coefficient of interest. In a further implementation, a mark decoding system is configured to extract the embedded message from the image data.

摘要： To render digital content determined to be in an encrypted rights-protected form, each available license corresponding to the digital content to be rendered is identified, where each such license includes a decryption key (KD) for decrypting the digital content to be rendered, and where the decryption key (KD) in the license is encrypted according to a public key (PU) (PU(KD)). One of the identified licenses is selected and (KD) is obtained from the selected license by obtaining (PU(KD)) from the selected license and decrypting (PU(KD)) according to a private key (PR) corresponding to (PU) to produce (KD). The digital content is decrypted with (KD), and the decrypted digital content is provided for actual rendering.

摘要： An implementation of a technology, described herein, for facilitating the protection of computer-executable instructions, such as software. At least one implementation, described herein, may generate integrity signatures of one or more program modules—which are sets of computer-executable instructions—based upon a trace of activity during execution of such modules and/or near-replicas of such modules. With at least one implementation, described herein, the execution context of an execution instance of a program module is considered when generating the integrity signatures. With at least one implementation, described herein, a determination may be made about whether a module is unaltered by comparing integrity signatures. 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： Apparatus and an accompanying method, for generating a cryptographic identifier for a non-marked image and embedding that identifier within the image itself in order to generate a “watermarked” image; for subsequently detecting that watermark in a test image; and the watermarked image so formed. First, pixel values for a non-marked image are transformed, either directly or after being enhanced, into a series of transform coefficients. A set of pseudo-random perturbation values which collectively constitute the watermark is determined wherein each of these values is heuristically selected, such that all these values collectively satisfy a plurality of different mathematical constraints and each such value preferably equals a relatively small value in a predefined range. These perturbation values are then added to the transform coefficients. Resulting perturbed coefficients are then inversely transformed back to pixel values to form the watermarked image. To detect whether a test image contains the watermark and hence is a copy of the watermarked image, the pixel values for the test image are transformed to yield transform coefficients. A plurality of different mathematical tests or a majority type rule is then used, in conjunction with the perturbation values, previously used to create the watermark, and these transform coefficients to determine whether the perturbation values collectively exist in the test image, and hence whether the watermark is present or not.
