Patent number: 7552478Abstract: There is disclosed a network unauthorized access preventing system in which in a network to which one or more information processing apparatuses and a network unauthorized access preventing apparatus are connected, an unauthorized apparatus which is not authorized to access the network is prevented from accessing the network. The system includes an information processing apparatus which sends a correct ARP response packet to the unauthorized apparatus in response to an ARP request broadcast from the unauthorized apparatus, and a network unauthorized access preventing apparatus which sends an ARP response packet containing a false MAC address as the MAC address of the information processing apparatus to the unauthorized apparatus immediately after the correct ARP response packet is sent to the unauthorized apparatus.Type: GrantFiled: August 27, 2004Date of Patent: June 23, 2009Assignee: NEC CorporationInventors: Yoshinaga Seki, Shinji Hasei, Miho Uotani, Tatsuya Makino

Patent number: 7549175Abstract: A recording medium is applicable to information service system for receiving and transmitting information when a terminal device on the user's side accesses an administrative server, which is a server device, using a communication line such as the Internet. This recording medium (10a) comprises a lead-in region (16a), a data recording region (14a) positioned on an outer region than the lead-in region, and a lead-out region (12a) positioned on an outer region than the data-recording region. In at least any one of these regions (12a), (14a), and (16a), multiple pieces of identification information are recorded.Type: GrantFiled: April 17, 2007Date of Patent: June 16, 2009Assignees: Sony Corporation, Sony Disc & Digital Solution Inc.Inventors: Yoichiro Sako, Etsuo Shibasaki, Yoriaki Kanada, Akiya Saito, Koichi Nakajima, Shunsuke Furukawa, Kaoru Kijima, Akiko Inoue

Patent number: 7546640Abstract: Methods, systems, and media are disclosed for determining access rights to a resource managed by an application. One embodiment includes receiving a request by the application, wherein the request comprises an action a user seeks to perform on the resource. Further, the embodiment includes locating, based on the request, the resource in a structure having groupings of resources, wherein the groupings include a grouping having the resource. Typically the groupings comprise files having mappings of resources to assigned groups, and each group has an associated authorization table mapping roles or policies to users. Further still, the embodiment includes reading an authorization table associated with the grouping having the resource, and determining whether to grant the access rights for performing the action on the resource.Type: GrantFiled: December 10, 2003Date of Patent: June 9, 2009Assignee: International Business Machines CorporationInventors: David Yu Chang, Vishwanath Venkataramappa, Leigh Allen Williamson

Patent number: 7508939Abstract: In an image processing system according to the present invention, a first device encrypts image data generated by reading an image in a document, stores a decryption key for decrypting the image data, and transmits the image data to a data storing device. A second device receives the image data from the data storing device, sends a request for the decryption key to the first device and receives the decryption key, decrypts the image data with the decryption key, and performs print processing on the image data. Thus, users can easily perform print processing without the need to remember authentication and printer information.Type: GrantFiled: November 18, 2004Date of Patent: March 24, 2009Assignee: Canon Kabushiki KaishaInventor: Minoru Hashimoto

Patent number: 7486794Abstract: A data-processing arrangement (3) comprises a data-handling circuit (4) and a supply-current circuit (8) whose dynamic behavior is inherently chaotic in the sense of Lyapunov. The data-processing arrangement is arranged so that a power supply current (io) consumed by the data-handling circuit flows through the supply-current circuit.Type: GrantFiled: July 11, 2001Date of Patent: February 3, 2009Assignee: Gemalto SAInventor: Fabrice Pautot

Patent number: 7281269Abstract: Methods, data structures, and systems are provided to validate a message. A client receives a message in a first encrypted format. The message is decrypted and transferred to a remote server before being accessed by the client. In one embodiment, the client encrypts the message in a second encrypted format before transferring the message to the remote server. The remote server scans and validates the message and sends a result of the scan to the client. The client removes the message if the result indicates the remote server did not validate the message. Moreover, the client accesses or otherwise consumes the message if the result indicates the message was validated by the remote server.Type: GrantFiled: March 6, 2002Date of Patent: October 9, 2007Assignee: Novell, Inc.Inventors: A. Kent Sievers, Jay Parker, Preston D. Stephenson, Samuel F. Fletcher

Patent number: 7266693Abstract: A method of authenticating a user through a validated mutual authentication system is provided. In an exemplary embodiment, the method includes establishing a validating fractal image during an enrollment or other process. A plurality of fractal images are provided to a client during an authentication attempt by the user, and the plurality of fractal images includes the validating fractal image. Fractal image selection data is received from the client, and the system uses the received fractal image selection data to determine a fractal image selected by the user from the plurality of fractal images. The user is authenticated only if the fractal image selected by the user is the validating fractal image.Type: GrantFiled: February 13, 2007Date of Patent: September 4, 2007Assignee: U.S. Bancorp Licensing, Inc.Inventors: Eric R. Potter, Peter M. Skirvin
