Abstract:
1. A method, comprising: receiving, from a first compute device, a first record set, each record from the first record set including (1) an encrypted first identification string and (2) a hashed first attribute string; receiving, from a second compute device, a second record set, each record from the second record set having (1) an encrypted second identification string and (2) a hashed first attribute string; defining a third record set to include each record from the first record set that has a hashed first attribute string equal to a hashed first attribute string of a record from the second record set, each record from the third record set including (1) an encrypted first identification string and (2) an encrypted second identification string; receiving, from the first compute device, a fourth record set, each record from the fourth record set including (1) an encrypted first identification string and (2) a hashed second attribute string; receiving, from the second compute device, a fifth record set, each record from the fifth record set having (1) an encrypted second identification string and (2) a hashed second attribute string; defining a sixth record set to include each record from the fourth record set that has a hashed second attribute string equal to a hashed second attribute string of a record from the fifth record set, each record from the sixth record set including (1) an encrypted first identification string and (2) an encrypted second identification string; modifying the sixth record set to a modified state to exclude each record from the sixth record set that has an encrypted first identification string equal to an encrypted first identification string of a record from the third record set; defining a matched record set to include (1) each record from the third record set and (2) each record from the sixth record set in the modified state; and sending, to the second compute device, a signal indicative of the matched record set.
