Patent number: 7522726Abstract: A memory stores a hash value of content management data. When an IEEE1394 interface authenticates a personal computer connected thereto via a network, the IEEE1394 transmits content management data to the personal computer while receiving a hash data of the content management data from the personal computer. The IEEE1394 interface then determines whether the received hash value of the content management data matches the stored hash value of the content management data. This arrangement prevents the unauthorized copying of content data, and limits the number of uses of the content data.Type: GrantFiled: August 22, 2005Date of Patent: April 21, 2009Assignee: Sony CorporationInventors: Ryuji Ishiguro, Munetake Ebihara

Patent number: 7464398Abstract: Systems and methods of mitigating attacks, such as Denial of Service (DoS) attacks, in a communications network are presented. Source addresses of packets received at network devices are monitored in relation to known reliable addresses stored in a decision engine. If the source address, as stored in a source table, is known as being legitimate the packets are placed in a high priority queue for transmission at the highest rate. Packets with an unknown address are placed in a lower priority queue, the source address stored in a different source table, and the packet is serviced at a lower rate. Packets that become known to be legitimate are moved from the unknown table to the table from which high priority queues are serviced. In this way, an attacker that employs spoofing techniques is prevented from overtaxing network resources.Type: GrantFiled: May 19, 2003Date of Patent: December 9, 2008Assignee: Alcatel LucentInventors: Jean-Marc Robert, Scott David D'Souza, Paul Kierstead

Patent number: 7428307Abstract: A decryption processing unit decrypts encrypted content data using a license key Kc. When an elapsed time after reception of the license key (Kc) does not exceed a hold time at a time of the license key (Kc) included in reproduction control information (ACp), reproduction of encrypted content data continues. When the elapsed time exceeds the hold time at a time, the license key (Kc) is discarded, and a reproduction control unit again obtains a license key (Kc) from a memory card. Discarding and reobtaining license key (Kc) continues until an allowable output count of license key (Kc) from the memory card becomes zero. As a result, a reproduction time of encrypted content data can be controlled safely.Type: GrantFiled: June 26, 2002Date of Patent: September 23, 2008Assignees: Sanyo Electric Co., Ltd., Fujitsu Limited, Hitachi, Ltd.Inventors: Yoshihiro Hori, Takayuki Hasebe, Tatsuya Hirai

Patent number: 7197143Abstract: The Digital Video Authenticator (DVA) addresses law enforcement concerns for a means to authenticate digital video (DV) so that it will be admissible and trusted as evidence in court. The DVA is a peripheral device attached to a commercial digital video recording device whose purpose is to generate and record authentication data simultaneously as DV is recorded by the video recording device. Verification of the authenticity of a DV sample will be accomplished using non-real-time software tools. The DVA system and method reads digital video (DV) data from a digital video recording device; parses the DV data into elements representing video, audio, control and timing data; and creates digital signatures that can be used to validate the original DV tape. The combination of secure digital signatures and repeatability of the DV data stored on tape provides the basis for proving the original video has not been modified.Type: GrantFiled: January 16, 2003Date of Patent: March 27, 2007Assignee: The Johns Hopkins UniversityInventors: Thomas E. Duerr, Nicholas D. Beser, James H. Higbie, Donna C. Paulhamus, Michael A. Karls, Cash J. Costello, George R. Barrett

Patent number: 7146508Abstract: An image processing apparatus capable of preventing a copy protect function of a video or other contents signal from being disabled. An encoder encodes a contents signal from a DVD reproduction unit. A copy protect circuit performs copy protect processing on the encoded signal and outputs it. The copy protect circuit is controlled by control data input from CPU via an I2C_IF circuit. At this time, verification data from the CPU is stored in, and then read from registers in the I2C_IF circuit. Then, the CPU verifies the destination of transmission of the control data.Type: GrantFiled: August 27, 2002Date of Patent: December 5, 2006Assignee: Sony CorporationInventors: Tetsuya Hirano, Hiroshi Tajima

Patent number: 7131133Abstract: The encoded contents of a piece of delivered information is accompanied by an applicable time data indicating a specific time period for authorizing a particular mode of utilization. When a request for utilizing the contents is issued in an information utilization apparatus, it determines if the current time agrees with the time authorizing the requested utilization by referring to the time data annexed to the encoded contents. If the request is acceptable at the current time, a set of processing steps is carried out for decoding the encoded contents and other necessary operations. Thus, an information access control method can be adapted to have flexibility in setting charges and access requirements for the contents of information that can change the value and the mode of utilization with time.Type: GrantFiled: September 17, 1997Date of Patent: October 31, 2006Assignee: Kabushiki Kaisha ToshibaInventors: Yasushi Kawakura, Tetsuro Kimura, Takashi Suzuoka

Patent number: 7131006Abstract: Techniques are described for enabling authentication and/or key agreement between communications network stations and service networks. The techniques described include the negotiation and use of a cryptographic primitive shared between a service network and a home environment of a station. The techniques described also feature a key usage indicator, such as a sequence number, maintained by the service network and a station. Comparison of the key usage indicators can, for example, permit efficient authentication of the service network.Type: GrantFiled: November 9, 2000Date of Patent: October 31, 2006Assignee: Verizon Laboratories Inc.Inventor: Christopher Paul Carroll

Patent number: 7120251Abstract: A data player for reading contents encrypted by a decoding key from a digital medium, and playing the encrypted contents by using the decoding key which is stored in a key storage unit, comprises: a key obtaining unit for performing mutual authentication with the key storage unit to obtain the decoding key stored in the key storage unit; a key holding unit for holding the decoding key; a playback state obtaining unit for monitoring the playback state of the digital medium; and a contents decoding unit for decoding the encrypted contents by using the decoding key. The decoding key is obtained by the key obtaining unit and stored in the key holding unit, and the encrypted contents read from the digital medium is decoded with the decoding key by the contents decoding unit to play the contents. The decoding key stored in the key holding unit is discarded according to the playback state of the digital medium which is obtained by the playback state obtaining unit.Type: GrantFiled: August 18, 2000Date of Patent: October 10, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hirotsugu Kawada, Noboru Katta, Susumu Ibaraki, Makoto Tatebayashi, Shunji Harada

Patent number: 7088823Abstract: A method for controlling access to digital information is performed based on a plurality of decryption keys sent by the information provider. A first type of decryption key instructs a user's host system to reproduce the digital information in accordance with a first level of reproduction quality degradation. Additional keys may specify other degradation levels. The quality of the digital information may be degraded based on a time condition or a use condition. Alternatively, only a portion of the information may be made viewable by a user. In order to obtain full and unrestricted access, the user must obtain a type of decryption key from the provider which removes all previous limitations on reproduction quality degradation.Type: GrantFiled: January 9, 2002Date of Patent: August 8, 2006Assignee: International Business Machines CorporationInventor: John E.
