Part 1: system briefing

Software name

ID identifying system (ID card scanning and identifying, and fingerprint identifying)

The system adopts a 3-layer structure, conveniently realizing identification, comparison, and storage of local and remote ID card information and fingerprint information, and able to be conveniently expanded as required by the business logic.

Part 2: system structure

System structure under work mode:

3-layer structure: client side, network communication & comparison server, and database server

Standard connection:

Figure 1：

Application system structure of 3-tiers database

Fig 1：: Standard connection

Under the standard connection, all the client sides are connected with the application server through intranet, which is a IP network supporting various TCP-IP applications; The application server, besides of connected with the client side, is also connected with the local and central databases. Advantages: As a multi-layer structure and socket-based communication standard are applied, each layer may be run in various machines or the same machine. Uniform data format conversion will be used to complete data input and output through the TCP-Ip protocol provided by the machine, realizing functions of the whole system.

Collection and comparison mode for fingerprint data:

The fingerprint comparison applies the one-to-one fingerprint comparison mode, which quickens comparison and gives more precise comparison results. For the flow, refer to Fig 2.

Statement of the video taking system (optional)

1. Apparatus selection

Any video taking equipments with USB interfaces

2. Advantages:

This system, when integrated with the ID card scanning & identifying system and the fingerprint identifying system, can identify identities more accurately, and make convenience for future data check and identify identification by saving current personal information, as well as system extension.
