Patent number: 9100434Abstract: 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.Type: GrantFiled: July 5, 2013Date of Patent: August 4, 2015Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA SOLUTIONS CORPORATIONInventors: Takanori Nakamizo, Kenji Kojima, Ikuya Odahara

Patent number: 8863305Abstract: 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.Type: GrantFiled: September 2, 2009Date of Patent: October 14, 2014Assignees: Kabushiki Kaisha Toshiba, Toshiba Solutions CorporationInventors: Koji Okada, Tatsuro Ikeda, Masataka Yamada, Minoru Nishizawa, Takanori Nakamizo, Toshio Okamoto

Patent number: 8396218Abstract: 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.Type: GrantFiled: September 18, 2008Date of Patent: March 12, 2013Assignees: Toshiba Solutions Corporation, Yokosuka Telecom Research Park, Inc.Inventors: Shingo Miyazaki, Takanori Nakamizo, Akito Niwa, Koji Okada, Kouya Tochikubo, Shigeyuki Fukushima, Chiaki Ishikawa, Noboru Koshizuka, Ken Sakamura
