摘要

The method involves recording an update request of a data base of a computer system in a work table, and producing and recording a planned list of rules relative to the request in a rules table. The request is validated for being declared as valid. The planned list of rules in the rules table is evaluated for producing a response i.e. accepted update, to the update request. The update request is considered based on the evaluation of the rules. A degree of similarity with fraudulent request is evaluated in the data base.
