System and method for analyzing anonymous payment card data

A computer device for associating ownership of anonymous payment cards, said computer device comprising a processor communicatively coupled to a memory, said computer device programmed to:

• identify a target account number for a payment card from the memory;
• identify a set of transaction times associated with the target account number from the memory;
• and
• compare, by the processor, the target account number to each candidate account number of a set of candidate account numbers from the memory, wherein the comparing to each candidate account number comprises:
• identifying a first candidate set of transaction times associated with a first candidate account number of the set of candidate account numbers;
• comparing the target set of transaction times to the first candidate set of transaction times;
• and
• identifying the first candidate account number as a match candidate if the target set of transaction times and the first candidate set of transaction times do not include overlapping transaction times.

At least one non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein when executed by at least one processor, the computer-executable instructions cause the processor to:

• identify a target account number for a payment card from a transaction database;
• identify a set of transaction times associated with the target account number from the transaction database;
• and
• compare the target account number to each candidate account number of a set of candidate account numbers from the transaction database, wherein the comparing to each candidate account number comprises:
• identifying a first candidate set of transaction times associated with a first candidate account number of the set of candidate account numbers;
• comparing the target set of transaction times to the first candidate set of transaction times;
• and
• identifying the first candidate account number as a match candidate if the target set of transaction times and the first candidate set of transaction times do not include overlapping transaction times.
