Offline ticket anti-counterfeiting method based on distributed account book principle

Abstract

The invention discloses an offline ticket anti-counterfeiting method based on a distributed account book principle. The offline ticket anti-counterfeiting method comprises the following steps that ticket system nodes are divided into a ticket (ticket number) generation node, an issuing node, a transfer node, a user node and a ticket checking node; ticket system transactions are divided into ticket generation transactions, issuing transactions, circulation transactions, pre-check transactions, ticket checking transactions, pre-refunding transactions and ticket refunding transactions, wherein each node has own secret keys (including a public key and a private key), and each transaction of the system needs to be encrypted by multiple nodes; when a ticket selling system sells a ticket, multiple parties are taken from transaction nodes for encryption and common certification, each node encrypts data by using a private key according to a specified sequence, and finally a ciphertext is formed and stored. When a ticket checking system checks the ticket, decryption is carried out by utilizing the public key of the corresponding node in the transaction of the ticketing system according to an opposite sequence. A multi-party authentication mechanism is provided, so that a decentralized mutual trust effect is achieved, tampering resistance is improved, and secret key leakage of any party is insufficient to cause counterfeiting of transaction data.

Description

technical field [0001] The invention belongs to the field of computer software technology and offline ticket checking, in particular to an offline ticket anti-counterfeiting method based on the distributed ledger principle. Background technique [0002] The ticketing system includes a ticketing system and a ticketing system. [0003] The ticket sales system is a system for selling and distributing invoices; the ticket checking system is a system for verifying the legitimacy of tickets and converting them into funds, goods or services. [0004] Distributed ledger, a P2P network accounting method, the contract information in the distributed ledger is recorded in different nodes in a decentralized manner. [0005] Decentralization, because in the distributed ledger, the information of each contract is stored in multiple nodes, so the transaction and verification can not rely on the existence of the central server. If a node in the cluster fails, it will not affect other nodes...

AI Technical Summary

Problems solved by technology

[0008] The problem faced by offline ticket checking is: if the ticketing system and the ticketing system are disconnected at a certain time, the tickets purchased in the ticketing system will fail to check in because no information can be found in the ticketing system

One solution is to encrypt the ticket by the ticket server, and allow the encrypted ticket to be checked out after decryption. As long as the password of the ticket server is not leaked, security can be ensured. Once the password of the ticket server is leaked or broken, illegals can use the password to Forged tickets to get away with it
