A method and system for securing a transaction by a user involving a subscriber unit ("SU") (having a processor, a memory, and a display and configured to accept user input), a credential information manager ("CIM") (having a processor and a memory), and a transaction service provider ("TSP") (having a processor and a memory). A cyber identifier ("CyberlD"), a subscriber identifier ("SubscriberlD"), and subscriber information, each associated with the user, is stored in the CIM memory. A request for a transaction is sent from the SU to the TSP, which creates a transaction identifier ("TID"), stores the TID in the TSP memory and transmits the TID to the SU. The SU transmits an authentication request along with the TID and a SubscriberlD to the CIM. The CIM authenticates the received SubscriberlD with the SubscriberlD in its memory, and transmits verification request along with the TID received from the SU to the TSP. The TSP verifies the received TID with the TID in its memory and reports the result of the verification to the CIM. The CIM transmits the CyberlD and the subscriber information to the TSP, and transmits a transaction authorization to the SU. |
