  • Patent number: 9100434
    Abstract: According to one embodiment, a Web page falsification detection apparatus, a dynamic information falsification determination module determines whether extracted dynamic information corresponds to dynamic characteristic information, and extracts a plurality of static information items. A second generation module couples the extracted static information items, and generates second static characteristic information. A static information falsification determination module determines whether first static characteristic information matches with the generated second static characteristic information, and transmits the Web page information to a user terminal.

  • Patent number: 8863305
    Abstract: In a file-access control system according to an embodiment of this invention, control data in accordance with actions made is imparted, as an obligation-type policy, to a document file. Next, a policy evaluation control unit evaluates and executes the obligation-type policy imparted to the document file in accordance with the action to the document file. The execution of the obligation-type policy includes the controlling of a document application on the basis of an obligation fulfillment action. Therefore, an active control can be performed in accordance with any manipulation made to the document, and the access to the document can be changed.

  • Patent number: 8406422
    Abstract: A cryptographic module management apparatus searches for cryptographic module meta-information based on the category information of a requested cryptographic module and, if associated cryptographic module category information is contained in this cryptographic module meta-information, searches for the cryptographic module meta-information of an associated cryptographic module, to generate composite type cryptographic module evaluation information based on this cryptographic module meta-information, select a cryptographic module based on this composite type cryptographic module evaluation information, and read this cryptographic module from a cryptographic module storage portion and output such composite type cryptographic module evaluation information.

  • Patent number: 8396218
    Abstract: In a cryptographic module distribution system, a cryptographic management server apparatus encrypts a cryptographic module using a key shared by a cryptographic apparatus, and transmits the encrypted cryptographic module to a client apparatus. The client apparatus transmits the encrypted cryptographic module to a cryptographic apparatus. The cryptographic apparatus decrypts the encrypted cryptographic module using the key shared by the cryptographic management server apparatus, and transmits the decrypted cryptographic module to the client apparatus. The client apparatus stores the received cryptographic module.
