1 Introduction
In order to strengthen the management of scenic spots, enterprises, organizations, etc., to achieve intelligent management, supervision and recording capabilities, it also completely solves the security risks of multiple entry with one card in the past, as well as temporary entry and exit, and the unidentified identity of the user of the employee card. Fingerprint access control The channel management system came into being.
Lianjinghua Technology has designed and developed a fingerprint ticket system that combines a person with a card. The system mainly uses IC card technology, fingerprint recognition technology, and computer network technology to uniformly manage the entry and exit of tourists in the entire scenic area and ticket sales, and improve the overall management capabilities of the scenic area. It has modern image, integrated management, and real-time information. Features such as reliability, anti-counterfeiting reliability, and accounting rigor.
Electronicizing the traditional manual ticket sales, while realizing the full automation and standardization of ticket management, can fundamentally solve the current situation of difficult ticket inquiry and high labor intensity of ticket sales, and improve the efficiency of ticket management and the quality of service to customers.
2. Design of fingerprint ticket card
(1) Choice of fingerprint ticket card chip
In order to reduce the hardware cost of the card as much as possible on the basis of ensuring the security of the ticket card, the Lianjinghua fingerprint electronic ticket system adopts the SLE 4428 IC card produced by Siemens and widely used in my country.
SLE 4428IC has the following characteristics:
1. With 1024×8-bit EEPROM memory;
2. Use bytes as the addressing unit;
3. With 1024×1 bit protected memory, the protected memory cannot be undone after it is set;
4. Three-wire serial bus;
5. It can perform 100,000 erasing and writing operations;
6. The data can be stored for 10 years;
7. There are 2 bytes of PSC program encryption bits in the card, and the data can be written only after the password is verified correctly.
The total capacity of the card is 1024 bytes. Except for the first four bytes of the card manufacturer’s factory number, the last three bytes of passwords and error counts, the number of available bytes is 1017 bytes.
Based on the above characteristics, the SLE 4428 IC card can fully meet the requirements of the fingerprint electronic ticket system for IC card capacity and ensure the security of the card.
(2) Information distribution in the fingerprint ticket card
Fingerprint IC card tickets are used as vouchers for tourists and normal users to enter and exit scenic spots or participate in certain activities. According to the different types of customers used, there are two types of ticket cards as follows:
1. Conventional ticket card: We usually sell tickets to tourists. Tourists can visit specified attractions or use certain facilities (such as cable cars, etc.) with their tickets. Such tickets are generally sold to tourists by way of price sales.
2. Special ticket card: is a ticket issued to tour guides, internal residents, staff or vehicles, etc., that is, the so-called management card or customer card. Holders of this type of ticket can enter and leave the park or use certain facilities (such as cable cars, etc.) with their tickets. This type of ticket is generally issued to relevant personnel (may be free of charge, or a certain fee may be charged), and it is required Regular review.
(3) The use process of fingerprint ticket card
1. Tourists buy a blank card from the ticket office, and when they enter the scenic area for the first time from any entrance of the scenic area, the gate gate equipped with a fingerprint recognition system and smart card reading and writing device will encrypt the card holder’s fingerprint and store it in the smart card. And record today’s date on the card. The gate is released and the user enters the scenic area.
2. When the user enters the scenic area again, the card must be inserted into the smart card reader device in the gate. The reader device first reads the user’s fingerprint information from the card and asks the user to compare the fingerprint. Only when the fingerprint comparison is successful and the card is within the validity period, the gate will be opened.
3. The overall structure design of the system
In order to ensure the timeliness and security of the data transmission of the fingerprint electronic ticket system, and to reflect the hierarchical management mode of the system, the entire scenic area should establish its own network system based on the existing telecommunication lines.
The network topology of Lianjinghua fingerprint electronic ticket system adopts multiple access methods:
(1) Internet access. No matter where the tourists are, they can inquire various information of the scenic area, and it is convenient for the scenic area to take the initiative to provide the latest information on the Internet in a timely manner.
(2) WAP access. Visitors can browse scenic spot information and book ticket cards by using mobile phones and other WEB methods.
(3) Remote access by agents. It is convenient for tourists to purchase tickets in different places and can improve the economic benefits of the scenic spot.
For future expansion of system functions, other third-party systems can also be connected.
4. Realization of system function modules
Lianjinghua Technology Co., Ltd. adopts the leading five-tiered b/s mode system structure, making it a safe, open and advanced system with high performance and price ratio.
○ is the presentation layer (Presentation),
○ Controller (Controller),
○ Domain layer (Domain),
○ Data Persistence
○ And the data source layer (Data Source).
In this B/S architecture, business logic is placed on the application server, a large number of data streams are also located between the middleware and the database, and the client simply sends a request, the server accepts the request and performs transaction processing and processing The result is returned to the client. This type of client is also called a “customer”.
The commonly used B/S architecture is a three-tier architecture, and all business logic is handled by Servlet and JSP programs or EJBs located on the application server.
The J2EE architecture based on the lightweight framework is safe and stable, has a clear structure, has good scalability and maintainability, and is very suitable for object-oriented design and development.
● B/S architecture has great advantages
1. Technology for the E-commerce Era
2. Robust system
3. Support remote remote control
4. Revolution in software operation, maintenance and upgrade methods
5. System Integration
6. Cross platform restrictions
● The software of the traditional C/S architecture needs to develop different versions of software for different operating systems. Faced with the rapid upgrade of many operating systems and software, using this architecture to develop software is undoubtedly a kind of IT investment for enterprises. Great risk. And the software products of the B/S architecture implemented by the Java language truly achieve “Write Once, Run Anywhere”. For the enterprise, it can avoid the risk of replacing the operating system in the future.
5 Conclusion
Lianjinghua Technology makes full use of computer software and hardware technology, network communication technology, biometric technology and IC card storage encryption technology to design and develop a fully functional, safe and reliable fingerprint electronic ticket system, which realizes a fingerprint electronic ticket that combines human and card The system allows visitors to enter the park with one card per person. It can not only improve the overall management ability of the scenic tourism industry, but also realize the scientific and standardized ticket management method, and it can also facilitate the tourists to purchase tickets in different places.
