A method and system for correlating cardholder identity attributes on a payment card interchange network using a computer device coupled to a database are provided. The method includes storing at a central store, personally identifiable information from an issuer for a plurality of payment card cardholders, the personally identifiable information encrypted to prevent payment card transaction data from being associated with the personally identifiable information, receiving, from a merchant, personally identifiable information during a payment card transaction, encrypting the received personally identifiable information, and comparing the encrypted stored personally identifiable information to the encrypted received personally identifiable information to determine a risk of fraud during the payment card transaction.
