Abstract: A system and method for performing a financial transaction over a network between a point-of-sale server and a financial server includes generating an identifier corresponding to a credit card number at a financial transaction server in communication with the point-of-sale server and the financial server. The transaction server sends the identifier to the point-of-sale server. When a customer chooses to use a stored credit card, the point-of-sale server sends the corresponding identifier to the transaction server. The transaction server retrieves the credit card number corresponding with said received identifier; and sends said retrieved credit card number to a financial server for processing.

Abstract: A method to build a resource access table in a system for controlling access to resources is disclosed. The protocol identifies a resource call in a process. Each of the resources accessed by resource calls are identified and routed to intrusion detection software for analysis. Permission is assigned to the resource, with regard to the process. A resource access table is written, with each entry identifying the process, the resource and the permission. When the process is executed and the process makes a resource call to the resource, access to the resource is controlled by the permission data entry in the resource access table entry of the resource access table.
