Method and system for personally identifiable information

Abstract:

A method for subverting open transmission of personally identifiable information through the use of tokenization includes: receiving a token request from an issuing financial institution; identifying a digital token; mapping the identified digital token to a primary account number; transmitting the identified digital token to the issuing financial institution; receiving a data request from a third party, wherein the data request includes the identified digital token; replacing the identified digital token in the data request with the mapped primary account number; transmitting the data request including the mapped primary account number to the issuing financial institution; receiving a data package including one or more items of personally identifiable information; and forwarding the data package.
