Estimating the term…
A method of optimizing attribute information of a product attribute stored in a product database is provided. The product database includes update information comprising a time that the attribute information has last been updated and correction history information including recorded samples of new attribute information. The attribute information is used as a security measure in a self-checkout purchasing system to confirm that a purchased product is the same product identified by the system after identification information of the product is input by a user of the system. The method includes conducting a query of the database for any products having said update information older than a predetermined period of time, having correction history information, and where the history information includes a plurality of recorded samples greater than a predetermined amount. The query establishes a query result, whereby revised attribute information is then calculated using the plurality of the recorded samples as data. The revised attribute information is then stored as the current attribute information at a time which replaces the time information contained in the database relating to the time the attribute information was last updated.
A method of optimizing a value associated with a characteristic of a product stored in a first field of a security database of a self-checkout system at an optimizing time, said security database also including a second field for storing identification information for said product, a third field for storing a last time when said value was last updated and a fourth field for storing at least one new value for said characteristic stored in said fourth field between said last time and said optimizing time, said value being used in a comparison to a second value associated with said characteristic and detected in a security area of said self-checkout system during a purchasing transaction, said comparison used as a security measure to confirm that a product placed in said security area during said purchasing transaction is the same product identified by said system after said system identifies said product via identification information input by a user of said system, said method comprising:
An apparatus for optimizing characteristic information comprising a value for a characteristic of a product stored in a security database of a self-checkout system, said security database including update information comprising a time that said characteristic information has last been updated and correction history information including recorded samples each comprising a new value for said characteristic information, said characteristic information used to compare to a second value associated with said characteristic detected by a security device of said self-checkout system, said characteristic information used as a security measure to confirm that a product placed in said security area is the same product identified by said system after identification information of said product is input by a user of said system, said apparatus comprising:
A system for optimizing a security database for products purchased with a self-checkout system comprising:
Computer readable media having computer-executable instruction for performing a method comprising:
A computer-readable medium having stored thereon a data structure comprising:
