Abstract:
A method of authenticating an executable application program which has a unique signature associated therewith and which has been previously installed in a memory of a self-service terminal by a non-customer of the self-service terminal, the method comprising the steps of:(a) retrieving the unique signature of the executable application program from the memory of the self-service terminal when a customer of the self-service terminal requests a desired self-service transaction to be carried out;(b) comparing the unique signature retrieved in step (a) with a number of signatures stored in a look-up table to determine if the unique signature matches one of the signatures stored in the look-up table; and(c) authenticating the executable application program to allow the executable application program to be executed only when a match occurs in step (b) and thereby to allow the self-service customer to complete the desired self-service transaction.
