Patent number: 7188086Abstract: The present invention provides a confidential information management system which allows users to securely obtain confidential information files containing various confidential information, which files are securely stored in the present system, anywhere and anytime, using a minimum of confidential information. A confidential information file and encoding/decoding software are downloaded to an information terminal from a confidential information managing server and an encoding/decoding software managing server, respectively, so that the confidential information file is decoded on the information terminal by using the encoding/decoding software. The present system is applicable to various (computer) systems which store and manage confidential information (ID numbers, passwords, encryption keys, digital certificates, etc.) for use in user verification.Type: GrantFiled: September 7, 2001Date of Patent: March 6, 2007Assignee: Fujitsu LimitedInventors: Takashi Shinzaki, Takashi Morihara

Patent number: 7079671Abstract: Section images of a human body part are continuously input by relative movement with respect to a read unit in an image input step, a living body section image including a character shape from an input section image group in a character area section step, and, when living body section images which include character shapes which are chronologically continuous are selected, the living body section images are connected to each other to generate a connected living body image in an image connection step. In the collation step, the connected living body image including the character shapes and living body section images which include character shapes which are not connected to each other are collated with a corresponding portion in reference information of a human body part which is registered in advance to authenticate an identical person.Type: GrantFiled: October 28, 2002Date of Patent: July 18, 2006Assignee: Fujitsu LimitedInventors: Takashi Morihara, Yusaku Fujii

Patent number: 6871320Abstract: A tag information separating unit separates a tag identified from a character train stream and outputs as tag information. A tag code replacing unit arranges a tag code for identification to a position of the character train stream in which the tag was separated. A character train coding unit compression encodes the character train stream including a tag code which is outputted from the tag code replacing unit. A data reconstructing apparatus reconstructs the character train stream by the operation opposite to the compression.Type: GrantFiled: July 13, 1999Date of Patent: March 22, 2005Assignee: Fujitsu LimitedInventors: Takashi Morihara, Hironori Yahagi, Noriko Satoh

Patent number: 6747582Abstract: A dictionary in which a character train serving as a processing unit upon compression has been registered is stored into a character train dictionary storing unit. In a character train comparing unit, the registration character train in the character train dictionary storing unit and a partial character train in non-compression data are compared, thereby detecting the coincident partial character train. A code output unit allocates a predetermined code every partial character train detected by the character train comparing unit and outputs. The character train dictionary storing unit allocates character train codes of a fixed length of 17 bits to about 130,000 words and substantially compresses a data amount to the half or less irrespective of an amount of document data.Type: GrantFiled: December 3, 2002Date of Patent: June 8, 2004Assignee: Fujitsu LimitedInventors: Takashi Morihara, Yahagi Hironori, Satoh Noriko
