Abstract:
A computer-implemented method for de-identifying data by creating tokens through a cascading algorithm includes the steps of processing at least one record comprising a plurality of data elements to identify a subset of data elements comprising data identifying at least one individual; generating, with at least one processor, a first hash by hashing at least one first data element with at least one second data element of the subset of data elements; generating, with at least one processor, a second hash by hashing the first hash with at least one third data element of the subset of data elements; creating at least one token based at least partially on the second hash or a subsequent hash derived from the second hash, wherein the token identifies the at least one individual; and associating at least a portion of a remainder of the data elements with the at least one token.
