Abstract
A system for identifying a seal stamp comprises a memory having stored therein two impression reference patterns, namely an original reference pattern and a latest reference pattern, for the seal stamp. An impression pattern read by a reader is collated with the latest reference pattern, and when the patterns are found to match, the read impression is verified and the latest reference pattern in the memory is updated with use of the read impression pattern. If the patterns are found not to match by the collation, the read impression pattern is collated by the original reference pattern. When the two patterns are found to match by this collation, the read impression is verified. The original reference pattern is updated when desired. The system is also useful for identifying other objects such as speech.
Claims8
A system for indentification verification by comparing a current information input with information previously stored, comprising:
- a memory having, for each of a plurality of items to be identification verified, a first memory area for storing original reference information for that item and a second memory area for storing latest reference information for that item;
- means for generating from an item to be identified, current impression information;
- first means for comparing, based on first predetermined criteria, the current impression information with the latest reference information stored in said second memory area associated with that item;
- means, in the event of a favorable comparison by said first comparing means, for updating the latest reference information in memory based on the current impression information;
- second means for comparing based on second predetermined criteria and in the event of an unfavorable comparison by said first comparing means, the current impression information with the original reference information in said first memory area associated with that item;
- and
- means, in the event of a favorable comparison by said second comparing means, for updating the original reference information based on the current impression information.
