Abstract:
1. A method for limiting exposure of secured data in an authenticated transaction over multiple systems, the method comprising: receiving a transaction request from an authenticated user of a client system on an initial system; deriving from the transaction request a first request for the secured data stored on an external system independent of the initial system and a second request for unsecured data stored on the initial system, the first request and the second request being combined in the transaction request; transmitting to the external system a token request corresponding to the first request for the secured data, the external system being configured to generate a token associated with the token request; receiving on the initial system the generated token from the external system; and transmitting from the initial system to the client system the token and the requested unsecured data stored on the initial system; wherein the token is presentable by the client system to the external system to retrieve the secured data stored on the external system independently of the transmission of the unsecured data upon validation of the token thereby by the external system.
