Enabling Credit Card Encryption
PeopleSoft PeopleTools uses encryption technology to secure critical PeopleSoft data. PeopleSoft Expenses uses this feature to for credit card security by encrypting credit card information received into the PeopleSoft Expenses application as data.
Credit card encryption is delivered as enabled. However, to maximize the credit card encryption feature, you must establish a secret encryption key using the Algorithm Keyset page. The credit card data is masked when printed or displayed online, and only the last four numbers of the credit card number are visible.
Note: Credit card data contained in files received from suppliers is not encrypted using the PeopleSoft PeopleTools feature until the credit card data is loaded. Therefore, additional precautions should be taken to secure the files received from suppliers while that data exists on the file system.
