Electronic ticket system and method based on public key basic infrastructure

Abstract

The present invention discloses an electronic ticket system based on public key installation (PKI) and its method. The invented system includes user ticket storage device, ticket storage device initialization subsystem and electronic ticket on-line booking subsystem, and further includes electronic ticket verification subsystem and electronic ticket monitoring subsystem. Said invention also provides the working principle of said electronic t6icket system and its concrete operation method.

Description

technical field [0001] The invention relates to an electronic ticket technology containing a digital signature, in particular to an electronic ticket system and method based on a public key infrastructure (PKI). Background technique [0002] At present, ticketing systems are generally divided into traditional paper ticketing systems and electronic ticketing systems. With the improvement of scanning and printing methods, the means of counterfeiting and copying paper tickets are also increasing, and the anti-counterfeiting and verification of traditional paper tickets are becoming more and more difficult. The traditional paper ticket system can no longer meet the requirements of modern ticket sales and management. The following disadvantages are exposed in use: [0003] (1) The anti-counterfeiting of paper tickets is based on the manufacturing materials and manufacturing process of tickets. The technologies used include: ultraviolet printing, optical ink, micro-text technolo...

AI Technical Summary

Problems solved by technology

[0004] (2) Paper tickets are generally verified by human eyes, and it is difficult to guarantee the correctness of the verification;

[0005] (3) Paper tickets have poor wear resistance. After wear and tear, the physical and chemical information on the tickets may be lost;

[0006] (4) The production of paper tickets requires special equipment, and it is difficult to support online ticket sale and management;

[0007] (5) Paper tickets can generally only be used as a certificate for users to enter the venue, and cannot cooperate well with the monitoring system in the venue to dynamically monitor and guide the personnel in the venue

[0010] (1) The two-dimensional barcode ticket has the characteristics of "copying and valid". In order to distinguish the legitimate ticket subject, the personal information of the ticket subject needs to be added to the ticket, which cannot support the anonymous use of the ticket;

[0011] (2) When printing two-dimensional barcodes, a special barcode printer is required; when verifying two-dimensional barcodes, a special two-dimensional barcode reading device is required, which cannot well support online ticket sales and verification

[0013] (1) The certificate + password ticket system cannot support the anonymous use of tickets;

[0014] (2) The ticket sales network and the ticket verification network of the certificate + password ticket system are connected together. Since the ticket sales network is connected to the Internet, the ticket verification system may be attacked by the network;

[0015] (3) When verifying the ticket of the certificate + password ticket system, it is necessary to connect to the database of the ticketing system, and criminals may destroy its communication, so that the ticket verification process cannot be carried out smoothly

[0019] (3) The IC card ticket system lacks a verification mechanism for the legitimacy of the IC card. Criminals may use forged IC cards to purchase tickets, and then read and copy the ticket information in the forged IC card.

[0021] (1) When users purchase tickets, they need to provide their personal biometric information to the ticket issuer, which causes the leakage of personal privacy of ticket users;

[0022] (2) The extraction of biological information requires special scanning equipment, and it is difficult to sell and verify tickets online;

[0023] (3) At present, when biometric information is identified, the amount of data processing is large and the time required is relatively long, which reduces the verification speed of tickets

[0025] (1) There is a lack of verification means for the electronic ticket carrier, and the ticket data information is easily extracted and copied by criminals;

[0026] (2) Special scanning and printing equipment are required for the sale of electronic tickets, which cannot well support online ticket business;

[0027] (3) It is difficult for the electronic ticket system to support both the anonymous use of tickets and the refund and loss reporting of tickets
