Abstract
An electronic ticket system for virtually preventing forgery, copying and other unauthorized uses of electronic tickets; for proving to a third party the contents of an electronic ticket contested between a user and an issuing party; and for protecting users' anonymity upon ticket use. The system comprises a ticket creating and issuing device, a ticket proving device, and a ticket verification device. A ticket creating unit in the ticket creating and issuing device creates specifications of a ticket representing a predetermined service or product in response to a ticket creating request. A ticket issuing unit of the ticket creating and issuing device, in reply to a ticket issuing request, issues the corresponding ticket using as input a ticket identifier, a proving identifier, a ticket specification identifier, and ticket added information. The ticket proving device gets a ticket issued by the ticket issuing unit and communicates with the ticket verification device to prove the possession of the ticket. The ticket verification device has a ticket verifying procedure and, on getting the ticket identifier created by the ticket creating unit, communicates with the ticket proving device to verify the ticket.
