Patent ID: 7664731

Claim:
A method, implemented using a computer system, for processing data comprising: receiving an access record having a plurality of identifiers, the access record corresponding to an entity; transforming, using the computer system, at least one of the plurality of identifiers in the access record into a pre-determined standard representation of the at least one of the plurality of identifiers; utilizing a cryptographic algorithm to process, using the computer system, at least two of the plurality of identifiers in the access record, including the pre-determined standard representation, to form a cryptographic algorithm result corresponding to previously stored data related to the entity, wherein the previously stored data related to the entity was stored according to an output of the cryptographic algorithm; matching, using the computer system, the cryptographic algorithm result with the previously stored data related to the entity; if the cryptographic algorithm result matches the previously stored data related to the entity, outputting, using the computer system, a result indicating a match; and if the cryptographic algorithm result does not match the previously stored data related to the entity, outputting, using the computer system, an empty result.
