Abstract: A secure database system comprises a server having a database including at least one personal information table and at least one further table containing information relating to the persons whose details are stored in the personal information table. The keys of the tables in the database are unrelated, so that it is impossible to determine solely from information in the server which record in the further table corresponds to which record in the personal information table. Thus, even if a hacker obtains access to the database, the hacker will not be able to relate information in the different tables. Each legitimate client uses an encryption process to convert a personal identifier value, which identifies the record relating to a particular person in the personal information table, into a pseudo-identifier value, which identifies a record relating to the same person in the further table.

Abstract: The present invention allows assuring security of processing by the application itself without depending on the operating system. When a plurality of clients perform joint operation via a common server, the processing permitted for each server to perform to the server is predetermined, and when a user requests a processing which is not permitted, the client rejects this request. By this, the security among a plurality of clients can be assured without depending on the server.

Abstract: A verification system is configured to verify the presence of an entire data set before individual data items within the set can be accessed for playback or other processing. Each data item in the data set comprises one or more sections, and the totality of sections constitute the complete data set. Each section of the data set contains a watermark that includes an identifier that confirms the presence of the section as originally recorded. The presence of the data set is confirmed by checking the watermarks of randomly selected sections to verify that the original sections that formed the data set are present, or, by maintaining a record of accessed sections to verify that a substantial portion of the data set is present. To allow for the possible noise-corruption of one or more watermarks, the verification system is configured to allow for a less-than-absolute verification.

Abstract: To dynamically embed information with a digital content taken into account a digital information embedding device includes an input block receiving an image, a feature value parsing block detecting a feature value of at least a partial area of the input image, and an information embedding block modifying the area, based on the detected feature value. A feature value detected can be referred to to modify an area. This allows a content of an image to be considered in embedding digital information.

Abstract: A method of marking an original text document in which existing inter-word blank characters are altered is disclosed. A reversible transform is first applied so that inter-word intervals become exclusively comprised of odd numbers of blank characters. Transformed original text is then split in two subsets and an authentication pattern is merged into first subset by adding inter-word blank characters. A blurring pattern is computed which further modify the number of blank characters so as to hide the authentication pattern. Second subset is blurred too before subsets are recombined to obtain a marked text susceptible of authentication.

Abstract: A method, apparatus and system for electronically verifying that a person using an electronic apparatus is who the person claims to be. It may be used for computers, e-commerce, financial transaction cards, automotive access and ignition, security badges, building access, cell phones and any other application in which electronic identification of a person is required.

Abstract: A justification/authentication personal certificate system stores in a remote database a counterpart of an identifier and a digital watermark contained in the personal certificate. The personal certificate includes the digital watermark embedded in an authentic image such as a facial photograph, a retinal scan, or a fingerprint. When the personal certificate is used, the authentic image is read from the personal certificate, and the digital watermark information is extracted. The digital watermark information and the identifier are compared with the counterparts stored in the database. If the extracted digital watermark information is identical to the information in the database, then the personal certificate is judged to be unjustifiable. In one embodiment, at least one of the identifier and digital watermark are changed each time the system justifies the personal certificate.

Abstract: A process controlling unit included in a multifunction-device controller sends an acquired ID number and a request for identifying the user corresponding to the ID number, to a controller server. The controller server searches a user management file for user information corresponding to the ID number. The controller server sends, to the multifunction-device controller, information representing that user verification is successfully made when user information is acquired. Upon reception of such information, the process controlling unit permits the verified user to operate a copier making copies of documents. Upon completion of the copying operation, the process controlling unit acquires information representing the number of copies made by the user. Then, the process controlling unit creates usage information of the copier, and sends the created usage information to the controller server. The controller server stores the received usage information into a usage-information management file.

To ensure privacy of the users' personal information, each user is assigned a unique Universal Anonymous Identifier (UAI). The UAI is generated by a trusted third party and provided to the Web site operator. The Web site operator then indexes the users' personal information by UAI. Only the user has the ability to correlate his/her true identity with his/her personal information.

Abstract: If a tracking pattern superimposed on print data is discriminated, a malicious user may tamper the pattern, resulting in a deterioration in the reliability of the tracking pattern itself. According to this invention, therefore, a tracking pattern generating unit generates a tracking pattern, and a data addition processing unit adds the tracking pattern to image data. An encryption processing unit encrypts the image data to which the tracking pattern is added to make it difficult to detect that the tracking pattern is added, and transmits the resultant data to a printing apparatus. This makes it difficult to discriminate the tracking pattern from the image data, thus providing the highly reliable tracking pattern.

Abstract: When a firewall receives, from a mobile terminal via the Internet, an access request which designates a URL including a http, a domain name containing a host name, a service name, a machine name, and a specific port number, the firewall outputs the request to a corresponding port of a relay server. The relay server sends an authentication page to the request source terminal to cause the user to input authentication data, and causes an authentication server to authenticate the request source user on the basis of the input authentication data. If authentication succeeds, the relay server checks whether the authenticated user can receive a service represented by the service name and machine name in the URL. If the user can receive the service, the relay server sets a session, and grants request/response communication between the mobile terminal of the request source and the request destination in the session.

Abstract: A first node (client) (1) is in communication with one of a plurality of second nodes (5, 6, 7) connected to a local area network (LAN) (4) via a virtual private network including a link (3), such as the Internet, and a selected one of a plurality of third nodes (gateway servers) (21, 22, 23). Communication between the first node (1) and the third nodes (21, 22, 23) is encrypted, whereas communication between the third nodes and the second nodes (5, 6, 7) is unencrypted. Communication from the first node (1) to one of the second nodes (5, 6, 7) is initially set up via a selected one of the third nodes after suitable authentication. If that third node should subsequently fail, an alternative third node can be used. To detect the failure of a third node, the first node (1) sends a “heartbeat” packet (failure detection signal) to it. An operational third node responds with an answer, indicating that all is well.

Abstract: In the semiconductor memory device, a control circuit generates various commands for a memory cell array according to an internal command control signal and an internal address signal output from an input switching circuit for switching an input source of the command control signals and the address signal between an external terminal and a BIST circuit. In the BIST mode, the input switching circuit cuts the signal input from the external terminal and generates the internal command control signal and the internal address signal according to an output signal from the BIST circuit. Transition to the BIST mode and return to the normal operation mode are indicated by a combination of signals supplied to the external terminal. Therefore, an interface between a built in BIST circuit and other internal circuits can be secured without an addition of a special interface specification.

Abstract: A LSI includes a logic circuit, a PLL circuit and a built-in self-test (BIST) circuit. When the PLL circuit detects a phase lock of the system clock signal of the LSI with a reference clock signal under the condition of presence of a test instruction signal, the PLL delivers a test enable signal to the BIST circuit. The BIST circuit responds to the test enable signal to test the logic circuit in a functional test. The BIST circuit transmits the test result data to an IC tester after the functional test. Throughput of the functional test can be improved by eliminating transmission of the test enable signal from the IC tester to the LSI.

Abstract: When recording digital data corresponding to a voice signal, a voice data recording and reproducing apparatus generates an error correction code and records this code together with the digital data in semiconductor memory.
