Granted: 1998-10-27
Abstract: An identification card and method and apparatus for producing and authenticating such an identification card.  An object or other entity for which the identification card will evidence identity, status or characteristics is scanned to produce a digital signal which is compressed, encrypted, and coded as a two dimensional barcode or as some other appropriate form of coding, which is incorporated into one portion of the identification card.  The image is also printed or otherwise embodied onto another portion of the identification card.  A text message maybe appended to the signal before it is encrypted and also printed as plain text on the identification card.  In one embodiment the signal representing the image is encrypted using a public key encryption system and the key is downloaded from a center. This key maybe changed from time to time to increase security. To facilitate authentication the corresponding decryption key is encrypted with another key and incorporated on the card. To validate the card the coded message is scanned, decoded, decrypted, expanded and displayed.  The card may then be authenticated by comparison of the displayed representation of the image and the displayed text message with the image and text message printed on the card.

Abstract: A management apparatus for volume-medium correspondence information for use in a dual file system is disclosed.  The apparatus has a volume-medium correspondence information management table for storing and managing volume-medium correspondence information during the operation of the dual file system.  A volume-medium correspondence information storage file stores, after a stop of the dual file system, volume-medium correspondence information which was in the volume-medium correspondence information management table immediately before that system stop.  The volume-medium correspondence information is updated in the volume-medium correspondence information management table when the media constituting dual files are to be altered and when the volumes into which the media are to be assembled are to be altered.  During the operation of the dual file system, the latest volume-medium correspondence information in the volume-medium correspondence information management table is written into the volume-medium correspondence information storage file.          When the dual file system is to be re-actuated, volume-medium correspondence information stored in the volume-medium correspondence information file is recovered into the volume-medium correspondence information table after the re-actuation.  When the dual file system is to be re-actuated, the volumes in an off-line state are provisionally allocated to dual files including a blockaded medium on the basis of the volume-medium correspondence information in the volume-medium correspondence information table recovered.

Abstract: An electronic element A1 has a lead electrode at the edge and a supporting member A2, positioned so that it faces the electronic element across a gap G. The supporting member A2 also has an external connecting terminal A5 at a location opposite the lead electrode A4. A resin layer A3 is positioned between electronic element A1 and supporting member A2, indented by the distance d from the edge of the electronic element A1. The resin layer bonds the electronic element (A1) and supporting member A2. The relationship of the distance d with G should satisfy this expression; d > G. A solder A6 fills the space created by the gap G between the lead electrode A4 and the external connecting terminal A5 over the distance d which is the distance from the edge of the electronic component A1, to the resin layer A3. The solder connects the lead electrode A4 and the external connecting terminal A5.
