A computer-implemented method includes: obtaining, by a computing device, an original Personal Account Number (PAN) to be transformed; transforming, by the computing device, the original PAN to form a transformed PAN; performing, by the computing device, a verification on the transformed PAN; determining, by the computing device, whether the transformed PAN passes verification; and storing or outputting, by the computing device, the transformed PAN based on determining that the transformed PAN does not pass verification, wherein the original PAN is later recovered from the transformed PAN to process a transaction.
