Abstract: A program for generating individual keys from a base key is stored in a memory in each SA card (12) in the production of SA cards. Next, the base key is stored in a secret area in the memory, data stored in which cannot be read out from outside, in the SA card (12) by an SA card issuing machine. When issuing individual user cards (13), a user card issuing machine transmits ID or the like of the card to the SA card (12), prepares the individual keys by use of the individual key generation program and stores the received individual keys in the secret area in the memory of the user card (13). At the time of use, the card ID or the like of the user card is transmitted from the user card (13) to the SA card (12) and the SA card prepares the individual key of the user card from the reception information and shares the individual key. In this manner, the IC card service system can execute various attestations by use of the functions such as encoding and decoding of data without making on-line inquiry to the center side.

Abstract: A hierarchy of border attribute data items is produced from a body of data such as the pixel values of an image. Each border attribute data item indicates an attribute of a border of an analysis region of the image. The starting border attribute data items, at the lowest level of the hierarchy, are produced by operation on the pixel values. Each border attribute data item at a higher level in the hierarchy is produced by operating on a respective set of data items from the next lower level. The border attribute data items can indicate, for example, the number of black pixels in each border or the number of edge pixels in each border. Or the border attribute data items could include boolean values indicating whether any of the pixels in a border is a black pixel with a neighboring black pixel outside the border. For rectangular regions in a binary hierarchy, values for two borders can be added or logically combined at a first level and one of the values for the same two borders can be selected at the next higher level; one of the values for the other two borders can be selected at the first level and the values for those two borders can be added or logically combined at the next higher level.
