A computer implemented method indexes duplicate information stored in records having different unique addresses in a database. A fingerprint is generated for each record, the fingerprint is a singular value derived from all of the information of the record. The fingerprint is stored in the index as a unique fingerprint if the fingerprint is different than a previously stored fingerprint of the index. A reference to the unique address of the record is stored with the fingerprint. If the fingerprint is identical to the previously stored fingerprint, then store the reference to the address of the record with the previously stored fingerprint.
