  • Patent number: 8325915
    Abstract: When image data is outputted in a special image processing apparatus which has printed confidential data before, a server confirms whether the user who has instructed output is a permitted user or an unpermitted user. If the user is a permitted user, the server permits printing. If the user is an unpermitted user, the server confirms whether a predetermined period has elapsed after the special image processing apparatus was used last. If the predetermined period has elapsed, the server permits printing. If the predetermined period has not elapsed, the server restricts output by stopping printing or by document filing for storing image data. Thus, by restricting use by an outside user, leakage of confidential data is prevented.

  • Patent number: 8144368
    Abstract: This disclosure describes methods for using embedded auxiliary signals in documents for copy detection and other applications. In on application, the auxiliary signal is formed as an array of elements selected from a set of print structures with properties that change differently in response to copy operations. These changes in properties of the print structures that carry the embedded auxiliary signal are automatically detectable. For example, the changes make the embedded auxiliary signal more or less detectable. The extent to which the auxiliary data is detected forms a detection metric used in combination with one or more other metrics to differentiate copies from originals. Examples of sets of properties of the print structures that change differently in response to copy operations include sets of colors (including different types of inks), sets of screens or dot structures that have varying dot gain, sets of structures with different aliasing effects, etc.

  • Patent number: 8117455
    Abstract: A method of authenticating an object in which a computer system receives indicating data from a sensing device. The indicating data is generated in response to sensing of coded data provided on or in a surface associated with the object and is indicative of an identity of the object and at least part of a signature. The signature is in turn a digital signature of at least part of the identity. The computer system uses the indicating to determine a received identity and a received signature part, before using the using the received identity to determine at least a determined signature part. The determined signature part is then compared to the received signature part to authenticate the object.

  • Patent number: 8108906
    Abstract: The present invention provides an electronic document authenticity assuring method in which a series of procedures concerning redactable signature are divided into procedures dependent on a document to be signed and procedures dependent on a redactable signature method. Further, the present invention provides program codes that realize the divided procedures and a system comprising apparatuses for implementing those program codes. According to the present invention, even when type of electronic document to be signed is changed or added to, it is sufficient to add a procedure dependent on a document to be signed, without changing procedures dependent on redactable signature methods. Similarly, even when a redactable signature method is to be changed or added, it is sufficient to add a procedure dependent on the redactable signature method without changing procedures dependent on document to be signed.

  • Patent number: 8085978
    Abstract: Digital data is decoded from media signals (e.g., audio, images, video, etc.) using a distributed processing in which a first device receives and pre-processes the signal, and transmits it to a remote device for further decoding. One method pre-filters the media signal, leaving a residual from which digital data is decoded. Other arrangements progressively send portions of the signal for decoding operations.
