Abstract
Techniques are described that eliminate storage of primary account numbers (PANs) by third-party cloud applications executed in external networks. An example method includes receiving a query from an external network that includes a card reference number (CRN) and converting the CRN into a primary account number (PAN). The method includes modifying the query to include the PAN in place of the CRN and performing a service call to retrieve a record responsive to the query from a master account database using the PAN. The method includes, when the record includes the PAN, converting the PAN into the CRN via the tokenization server. Additionally, the method includes adding the record with the CRN to a query response and transmitting the query response to the external network.
