ELECTRONIC TICKET MANAGEMENT SYSTEM, ELECTRONIC TICKET MANAGEMENT METHOD, AND ELECTRONIC TICKET MANAGEMENT PROGRAM

摘要

The present invention addresses the problem of realizing a ticket management system that is resistant to falsification and is instantaneous. The present invention is characterized by comprising a user terminal and a node group, the user terminal having a terminal registration means that generates a terminal signature on the basis of user terminal information, and adds the terminal signature to a block on a main chain, and a transaction application means that generates an owner signature and adds the owner signature to the block on the main chain, the node group having a transaction approval means that generates a manager signature, adds the manager signature to the generated block on the main chain, and adds a transaction approver signature to a block on a generated sub-chain, the main chain having a block that includes a hash value based on the terminal signature, the owner signature, the manager signature, and the block on the sub-chain, and the sub-chain having a block that includes a hash value based on the transaction approver signature and transaction attribute information.
