Patent number: 6278984Abstract: A vendor ID is written to a system area of a write-once optical disk. When the write-once optical disk is loaded onto a write-once disk drive, a control CPU reads the vendor ID. The vendor ID is written into the header of software received through an interface unit. When the software is input to an SD circuit, the control CPU reads the vendor ID. The control CPU compares the vendor ID in the system area of the write-once optical disk with the vendor ID of the header of the software and checks whether or not the two IDs are identical. If the two IDs correspond to each other, the control CPU writes the software to the write-once optical disk.Type: GrantFiled: July 27, 1995Date of Patent: August 21, 2001Assignee: Fujitsu LimitedInventors: Satoshi Itami, Kazuo Nakashima, Kenichi Utsumi

Patent number: 5982886Abstract: In a method for preventing unauthorized use of a recording medium having a user accessible area and a user inaccessible area, first information is read from the user inaccessible area of the recording medium. The first information is compared with second information concerning a true recording medium (lawfully produced copy). It is then concluded that the recording medium is the true recording medium when the first information corresponds to the second information.Type: GrantFiled: October 11, 1996Date of Patent: November 9, 1999Assignee: Fujitsu LimitedInventors: Satoshi Itami, Kenichi Utsumi, Masahiro Nakada, Hiroshi Suzuki, Kazunori Naito, Kazuo Nakashima, Toshikatsu Narumi, Masaru Nakahara

Patent number: 5875247Abstract: A CD-ROM stores encrypted software. When a user desires to decrypt and install this software, an approval preparatory key is generated by an installer. This approval preparatory key is generated based on time data. When the user informs a center of this approval preparatory key, the center calculates a difference between this approval preparatory key and a decrypting key and vends this calculated result to a user in the form of an approval key. When the user inputs this approval key to an installer, the installer generates a decrypting key by adding the approval preparatory key to the approval key. The installer decrypts the software by this decrypting key and installs the encrypted software into a personal computer system.Type: GrantFiled: August 1, 1995Date of Patent: February 23, 1999Assignee: Fujitsu LimitedInventors: Kazuo Nakashima, Masaru Nakahara, Satoshi Itami, Kenichi Utsumi

Patent number: 3979771Abstract: This digital circuit generates a window during which the data bit transitions of phase encoded data may be read from magnetic tape. This circuit contemplates a system for reading nine track tape and comprises one phase lock loop and window generator for each track, and the logic and control circuitry necessary to deskew and output the data in the form of nine bit bytes. Each phase lock loop is individually free to correct itself to conform to the variations of its own track, and the control circuit can compensate for a total skew of up to four bit times.Type: GrantFiled: March 19, 1975Date of Patent: September 7, 1976Assignee: Xerox CorporationInventors: William Devore Taggart, Jr., Franklin Satoshi Itami
