Claim 11:
12. A method of verifying a second part of a divided temporary authentication value used in a secure transmission, wherein the method is performed by a service provider system having at least one computer server, the method comprising:
receiving, by the service provider system, the second part of the divided temporary authentication value, wherein the second part of the divided temporary authentication value has been generated by previously applying a hash function to first identification data, associated with a terminal, an item, or a user, and security data to generate a temporary authentication value and then dividing the temporary authentication value into a first part and the second part;
comparing, by the service provider system, the received second part of the divided temporary authentication value with each one of at least one available authentication value until a match is found between the received second part of the divided temporary authentication value and one authentication value, wherein the service provider system authenticates the terminal, the item, or the user using the received second part of the divided temporary authentication value; and
in response to the match having been found, continuing, by the service provider system, with an action initiated by the secure transmission.
