A method is disclosed. The method includes generating an initial key after interacting with an access device, storing the initial key at a key storage location, altering the initial key with a public key to form an altered key, and sending the altered key to a server computer along with an identifier for the access device. The altered key is changed to the initial key at the server computer and is stored with the identifier in a database in operative communication with the server computer. The initial keys that are stored at the key storage location and in the database are used to alter and restore transaction data associated with multiple financial transactions that are conducted using the access device.
