A trusted rendering system facilitates the protection of rendered digital works which have been rendered on a system which controls the distribution and use of digital works through the use of dynamically generated watermark information that is embedded in the rendered output. The watermark data typically provides information relating to the owner of the digital work, the rights associated with the rendered copy of the digital work and when and where the digital work was rendered. This information will typically aid in deterring or preventing unauthorized copying of the rendered work to be made. The system for controlling distribution and use of digital works provides for attaching persistent usage rights to a digital work. Digital works are transferred between repositories which are used to request and grant access to digital works.

  • Patent number: 8982411
    Abstract: An image processing apparatus includes: an extractor to extract colors used in input data; a converter to convert signals of the extracted colors into intermediate color signals each including three color signal components including brightness; an evaluator to evaluate recognizabilities of the colors based on the intermediate color signals; a generator to generate additional image data to be added to data for ordinary image formation based on a result of the evaluation and the input data; and a color convertor to convert the input data into the data for ordinary image formation.

  • Patent number: 8984095
    Abstract: The present invention relates to systems, apparatus, and methods of parsing a script within an HTML page. The method includes receiving a script object, where the script object includes text. The method further includes parsing the text of the script object for tokens and comparing the parsed tokens with a valid tokens list to determine locations within the text of the script object that include potential universal resource locators (URLs). The method includes parsing before and after the determined locations until complete URLs are constructed, and forwarding the complete URLs to a detector. The detector then determines whether the complete URLs are valid. The method then sends object retrieval requests to websites associated with the valid complete URLs.

  • Patent number: 8880404
    Abstract: An electronic device configured for adaptively encoding a watermarked signal is described. The electronic device includes modeler circuitry that determines watermark data based on a first signal. The electronic device also includes coder circuitry coupled to the modeler circuitry. The coder circuitry determines a low priority portion of a second signal and embeds the watermark data into the low priority portion of the second signal to produce a watermarked second signal.

  • Patent number: 8874910
    Abstract: The present invention provides an encryption method in which the encryption device stores data to be encrypted received via the input/output interface in its own memory, converts the data to be encrypted in the memory into a format required by the output device and transmits the converted data to the output device via the management interface, and the output device outputs the received information. The present invention also provides an encryption device for implementing the above method. The encryption device determines whether confirmation information has been received from a management interface, encrypts the data to be encrypted in the memory if the answer is positive, while performs no encryption or prompting to input correct confirmation information if the answer is negative. With the present invention, the user is allowed to view the contents to be actually encrypted, thereby avoiding such a case as signature counterfeiting or tampering.

  • Patent number: 8837721
    Abstract: The claimed subject matter relates to architectures and/or mechanisms that can facilitate issuing, embedding and verification of an optical DNA (o-DNA) signature. A first mechanism is provided for obtaining a set of manufacturing errors inherent in an optical media instance. These errors can be non-deterministic and can be encoded into the o-DNA that can be cryptographically signed with a private key, and then embedded into the source optical media instance. A second mechanism is provided that can decrypt the o-DNA with a public key and compare the authenticated errors to the observed errors to ascertain whether the optical media instance is authentic as opposed to a forgery or counterfeit.

  • Patent number: 8804954
    Abstract: The present invention relates to a secure method for reconstructing a reference measurement of a confidential datum on the basis of a noisy measurement of this datum. The method proposes a phase of enrolling a reference datum w having n digits, comprising at least the following steps: selecting an error correcting code C of a length L greater than n; generating an extended datum we by increasing the size of the reference datum w with L-n digits making up a key Sk; choosing a word c of the selected error correcting code C; generating the reconstruction datum s by combining the said word c with the said extended datum we. The invention applies notably to the authentication of individuals and to the generation of cryptographic keys, using for example biometric data or the physical characteristics intrinsic to an electronic component.

    Abstract: A method of color masking an image or video includes reading color values of an image sample of the image or video and a corresponding change of an attribute of the image sample. Based on the color values of the image sample, the change in the image sample attribute is mapped to a change in color components of the image sample that is equivalent to the change in the image sample attribute, yet reduces visibility of the change in the image sample attribute for the specific color values of the image sample.

When requesting an image data processing to a printer other than the printer to which an image data processing has been requested firstly, the client machine checks the security level of the other printer to which the image data processing is to be requested before requesting the image data distribution processing to the other printer. When selecting another printer to which the image data distribution processing is to be requested, the security level in each printer is sufficiently considered.
