Patent number: 9329959Abstract: A basic input/output system (BIOS) storage unit stores therein a BIOS. An operating system (OS) storage unit stores therein a plurality of OSs. A boot control unit sequentially starts the OSs stored in the OS storage unit. When each of the OSs booted by the boot control unit starts up, a boot information acquisition unit acquires boot information transferred between the OS and the BIOS. A regression analysis processing unit compares the boot information acquired by the boot information acquisition unit with expected values which are predetermined values for the boot information to determine whether the boot information coincides with the expected values.Type: GrantFiled: August 20, 2013Date of Patent: May 3, 2016Assignees: FUJITSU LIMITED, FUJITSU ADVANCED ENGINEERING LIMITEDInventors: Manabu Kanaya, Yasushi Sekiguchi, Takashi Ohhashi

Patent number: 8566597Abstract: When input data (f0) is read into a digital signature generating apparatus, a hash value (h0) is calculated. The hash value (h0) is stored to a storage area (M1), which has the highest priority rank among 5 storage areas. Subsequently, when input data (f1) is read in, a hash value (h1) is calculated. Since the storage area (M1) is already occupied by the hash value (h0), the hash value (h0) is read out from storage area (M1), emptying the storage area (M1). The read hash value (h0) and the hash value (h1) are concatenated, forming a concatenated hash value (h0|h1) and a hash value (h0,1) is calculated. The hash value (h0,1) is stored to a storage area (M2), which has the highest priority rank after the storage area (M1). When input data (f2) is read in, a hash value (h2) is calculated and stored to the storage area (M1).Type: GrantFiled: August 24, 2011Date of Patent: October 22, 2013Assignees: Fujitsu Limited, Fujitsu Advanced Engineering LimitedInventors: Masahiko Takenaka, Takashi Yoshioka, Fumitsugu Matsuo, Fumiaki Chiba

Patent number: 7894092Abstract: A print image generating program is capable of printing information that discourages fraudulent distribution of printed documents, irrespective of the type of printer. A print image generating apparatus has an application, a printer driver, a print management unit, and a virtual driver, and is designed to add tracking information that discourages distribution of printed documents when print data is printed. The print management unit monitors print requests from the application. When detecting a print request which was output from the application to the printer driver, the print management unit acquires and interrupts the print request destined for the printer driver. When the virtual driver receives a command from the print management unit, it acquires print data and tracking information, and generates tracking print image data by adding the tracking information to the print data, and gives the generated data to the printer driver.Type: GrantFiled: April 22, 2008Date of Patent: February 22, 2011Assignees: Fujitsu Limited, Fujitsu Advanced Engineering LimitedInventors: Satoshi Kasai, Michihiro Hokamura, Teruo Kumakiri, Katsutoshi Sekimoto, Hideyuki Hirano, Tomohisa Misawa, Kensuke Tsurumaki
