Patent number: 8745735Abstract: To aim to provide a monitoring system and a program execution apparatus that are capable of maintaining the security intensity even in the case where an unauthentic install module is invalidated. Install modules included in an apparatus each monitor an install module, which is a monitoring target indicated by a monitoring pattern included therein, as to whether the install module performs malicious operations. An install module that performs malicious operations is invalidated in accordance with an instruction from an update server. The monitoring patterns are restructured by the update server such that the install modules except the invalidated install module are each monitored by at least another one of the install modules. The restructured monitoring patterns are distributed to the install modules except the invalidated install module.Type: GrantFiled: November 20, 2009Date of Patent: June 3, 2014Assignee: Panasonic CorporationInventors: Manabu Maeda, Yuji Unagami, Yuichi Futa, Natsume Matsuzaki, Masao Nonaka, Hiroki Shizuya, Masao Sakai, Shuji Isobe, Eisuke Koizumi, Shingo Hasegawa

Patent number: 8726374Abstract: A management device detects whether any normal monitoring module that has not been tampered with exists by referring to monitoring results received from an information security device and selects, when existence is detected, one of the monitoring modules and assumes that the selected monitoring module has been tampered with. The monitoring device then successively applies a procedure to monitoring modules other than the selected monitoring module by referring to the monitoring results, starting from the selected monitoring module, the procedure being to assume that any monitoring module determining that a monitoring module assumed to have been tampered with is normal has also been tampered with. As a result of the procedure, when all of the monitoring modules are assumed to have been tampered with the management device determines the selected monitoring module to be a normal monitoring module that has not been tampered with.Type: GrantFiled: February 15, 2010Date of Patent: May 13, 2014Assignee: Panasonic CorporationInventors: Yuji Unagami, Manabu Maeda, Yuichi Futa, Natsume Matsuzaki, Masao Nonaka, Hiroki Shizuya, Masao Sakai, Shuji Isobe, Eisuke Koizumi, Shingo Hasegawa, Makoto Carlos Miyauchi

Patent number: 8683552Abstract: A terminal device controls delivery of information from a primary delivery destination to a secondary delivery destination. The terminal device stores a primary delivery condition regarding whether delivery of the information to the primary delivery destination is prohibited or permitted, and a trustability value showing a degree of trust of a user in the primary delivery destination. The terminal device judges whether or not to deliver the information to the primary delivery destination, by using the primary delivery condition. When judging to deliver the information, the terminal device calculates a secondary delivery condition using the trustability value and the primary delivery condition, the secondary delivery condition regarding whether delivery of the information from the primary delivery destination to the secondary delivery destination is prohibited or permitted. The terminal device then sends the generated secondary delivery condition to the primary delivery destination.Type: GrantFiled: February 17, 2006Date of Patent: March 25, 2014Assignee: Panasonic CorporationInventors: Masao Nonaka, Kaoru Yokota, Natsume Matsuzaki, Shogo Hamasaki, Kenji Hisatomi
