ABSTRACT:
A method and apparatus for matching at least a first input identifier with a reference identifier. A user provides an input identifier into a system, and the system produces a recognized identifier based on the input identifier. The system of the present invention perform a check-sum operation to determine whether the recognized identifier was recognized correctly. If the check-sum operation reveals that the recognized identifier is incorrect, the system of the present invention generates a plurality of substitute identifiers. The substitute identifiers are compared to a set of pre-stored reference identifiers. If a match is found between a reference identifier and a substitute identifier, the matched reference identifier is selected as corresponding to the input identifier provided by the user.
