REPRESENTATIVE VERIFICATION SYSTEM AND METHOD, AND ITS PORTABLE TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a representative verification system in which a representative verification server authenticated by a server certificate verifies a signature attached to sent data in place of a portable terminal with poor throughput. SOLUTION: The portable terminal 2 certifies that the representative verification server 3 is reliable when the portable terminal 2 authenticates the representative verification server 3. The portable terminal prepares processing contents for data sent from a service server 1 and sends signed data and the prepared processing contents to the representative verification server certified as reliable. The representative verification server verifies a signature in place of the portable terminal, and when the validity of the signature is approved, the representative verification server performs data processing with the service server according to the processing contents sent from the portable terminal.
