Hongda Large-scale Fingerprint Matching System
Overview
Hongda matching system is designed for large-scale AFIS and multiple application systems based on biometric identification technologies. Cogent PMA together with Hongda fingerprint products is the best solution for large-scale database with high reliability and speed, which will further improve system processing capacity and accuracy by using combined algorithm of fingerprint identification and face identification. In addition, this system has highly false accepted ability, can provide parallel processing capacity. It can be used for both public AFIS and other AFIS in specific fields. This system contains fingerprint algorithm and API used for editing the remaining fingerprint. Meanwhile, it can also process various fingerprint templates collected in the format of flat and rolled. Operating system supported Linux or Microsoft Windows is required.
Structure for Fingerprint Matching System
In view of ensuring security and confidentiality of data, and other related applications in the future, system will take the format of centralized data storage.
In order to improve fingerprint matching speed, fingerprint matching server employs the matching method of multithreading matching mode. At the same time, multi-matching servers can also be created to lower the request pressure generated by distributed Clients. .
All Client data will exchanged with Web server in the BS mode. The matching result of fingerprint data will be released through the Internet. The Client at all levels can make an operation in accordance to its authorization.
System Business Management Architecture consists of three level functional nodes：
1. Fingerprint matching server
Accept matching application
Create assignment and process matching
Generate matching results
2. Data receipt server
Receive fingerprint data
Analysis fingerprint data
Input fingerprint data
3. Terminal for fingerprint collection and matching
Collect fingerprint
Pack fingerprint image into file
Upload fingerprint data file
Send fingerprint matching application
Check fingerprint matching results
Data receipt server and fingerprint matching server play the leading role in the four mentioned above nodes, which function to store, match, analyze data and release the status of data matching. Executing results of fingerprint matching application will be monitored and processed at each terminal.
Our missions
We will persist on the following principles during the construction of our software system.
Then entire system design should be based on mature and advanced technology, so as to change traditional management method and working way, improve work efficiency and quality.
To select the most cost effective technical solution on the basis of meeting system requirements and demands in the future.
Data layer uses Oracle’s RAC parallel database technology which can process and allocate data storage, to ensure the efficiency of data access.
To monitor and manage the system resources, hardware, network, system performance through system tools, and create processing mechanism used to recover system.
To ensure the security of data storage through data backup and disaster recovery
To ensure the security of access system through administrator’s authorization
To ensure the open data integration through centralized database mode
To ensure the accuracy and reality of information
Administrator can make a correct decision through system enquiry and statistics.

HD AFIS |
Bureau of Public Security, Weihai City, Shandong Province
Sub-Bureau of Public Security, Xingtai City, Hebei Province, Bureau of Public Security, Huhehaote City, Inner Mongolia |
HD AFIS is a hi-tech software product, which is designed for criminal investigation by departments of Public Security at all levels. This system functions as to automatic fingerprint identification device. It features with fingerprint collection, acceptance, automatic analysis and matching, networking query, etc. This system can improve work efficiency and accuracy greatly due to its high speed of searches. This system also provides technical supports for identification of criminal suspect’s identity. |
Overview of HD AFIS applied at Bureau of Public Security, Weihai City, Weihai City.
HD AFIS uses WEB SERVICE-based three-layer structure, which includes fingerprint collection system, fingerprint processing system, matching server and Oracle database. The details are as follows.
一、Fingerserver Project
Fingerserver accesses business object at Middle Tier: business object is XML Web services, Client can use standard Internet protocol to communicate with business object from any platform. It functions on Web server, and provides performance and scalability required by distributed application
Five components include: database connected with Oraconn, ten-finger image data adapters ( orada_szinfo，orada_szimg，orada_dzinfo，orada_dzimg).
--------The above-mentioned five components performs the functions of
data processing. See finger.asmx.cs for details.
二、Fingeredit_web project
Tools include：minutia.cs,fingerfun.cs,bitmap.cs
minutia.cs: realize the storage, drawing, statistics, process and convert of point of characteristics
三、Numberbox auxiliary project：Extension of text editing, realize the input of digital number.
四、matchdll_win32 auxiliary project ：Invoke function as export function at DLL through remote matching server, so that it can be used in C#.
五、Exwdll.dsp project：Realize the compress and uncompress of fingerprint image
六、Fileconvert project：Realize the convert between HD fingerprint data format and standard data format from Ministry of Public Security
七、Oracle Datasheet：See SQL_THREE.txt

八、Matching Server Project：equipped with Fingerprint matching algorithm |
Bureau of Public Security of Beijing Municipal |
In order to monitor the policemen at communities, we developed on-duty management systems for policemen at Bureau of Public Security of Beijing Municipal. This system will identify every policeman’s fingerprint to know if she or he is on duty. An attendance report will be generated as well. Policemen at communities can also receive the command from high ranking level and submit the feedback to top management through the Internet. This system will greatly secure the community and ensure security of Network of Public Security. |

Fingerprint Identification System of Social Security |
Bureau of Social Security, and the same depts. at all levels in Jilin Province

With the construction of information, regularity and community, the original Pension Withdraw System can not meet the existing system requirement. The Fingerprint Identification System of Social Security is developed to adapt to the requirement of identifying individual ID. During the process of pension withdraw, we can identify the retired ID and his or her natural status through this system. Traditionally, we can withdraw a person’s pension using his or her card, even this person is dead or living in a different city. This causes a great loss to the nation. Therefore, Fingerprint identification system is a must to avoid the loss. This system will provide sophisticate solutions for social security, health care, unemployment, etc, which will improve and share information resources greatly. |
