ABSTRACT:
A method and system are disclosed for enhancing the security of transactions executed using a fixed unique system identifier. By the method of one such security enhancement the fixed unique system identifier is validated by a receiving server system according to a mathematical formula, most optimally a one way hash, from multiple input identifiers at least one of which is either secret or impossible to spoof. Other security enhancements include only delivering goods to an address matching user information already provided by the client system, only allowing trusted server systems to execute transactions, and only allowing trusted server systems to receive the fixed unique system identifiers.
