A security module for a transaction processing system

摘要

A security module (95) for a transaction processing system is disclosed. The transaction processing system includes a transaction manager (20) which runs in a first process and is responsive to transaction requests from one or more applications (10) and a service provider layer (30, 36, 37) adapted to relay transaction requests passed from said transaction manager to associated hardware (14) for execution. The security module is adapted to communicate with a supervisor application to receive and store application rights to execute transaction requests and is responsive to requests from the service provider layer to determine an application's right to execute a transaction request. Various Internet services can be requested from an automatic teller machine (ATM) using the invention.
