Embodiment 1

[0031] As the core of fingerprint identification in the present invention, each terminal fingerprint identifier is an independent device, and accesses the network 3 with an equal status. Such as image 3 The schematic diagram of the structural module of the preferred embodiment of the terminal fingerprint reader shown can be seen, and its structure includes a single-chip processing unit 21, a touch automatic power-on switch 27, and a fingerprint collector 22, an Ethernet, and a fingerprint collector 22 welded to the single-chip processing unit 21 through PCB lines. Peripheral circuits such as interface 24, control output port 23, watchdog unit 28 and LED indicator lights 261, 262, wherein said single-chip processing unit 21 and fingerprint collector 22 are connected on the same touch automatic power-on switch 27, through finger Power on the terminal system in the form of touch to obtain the voltage required for work. Therefore, the terminal fingerprint reader usually does not...

Embodiment 2

[0034] Such as Figure 4 As shown, it is a schematic diagram of the module structure of another embodiment of the terminal fingerprint identifier of the present invention. Depend on Figure 4 Compared image 3 It can be seen that the main components and connection methods of the terminal fingerprint reader are roughly the same, the only difference is that a keyboard input unit 291 is connected to the single-chip processing unit 21 through a line, so as to meet the needs of users of the network distributed fingerprint recognition system in special application environments. Capable of simple numeric entry.

Embodiment 3

[0036] Such as Figure 5 As shown, it is a schematic diagram of the module structure of another embodiment of the terminal fingerprint identifier of the present invention. Depend on Figure 5 Compared Figure 4 It can be seen that the main components and connection methods of the terminal fingerprint reader are also roughly the same, the only difference is that an LCD display 292 is connected to the single-chip processing unit 21 through a line, so as to satisfy the user's requirements for the network distributed fingerprint recognition system. interface needs. In addition, through the USB interface 25 drawn from the single-chip processing unit 21, the terminal fingerprint reader can be directly connected to a computer if necessary, and switched from single use to network application.

[0037] The keyboard input unit 291 and the LCD display 292 of the terminal fingerprint reader in the above-mentioned second and third embodiments are optional components, which do not limit th...

Abstract

The present invention discloses a network distribution type fingerprint identification system and a realizing method thereof. The network distribution type fingerprint identification system comprises a central server and at least one fingerprint identifier terminal which are connected through network. The network transmission based on TCP/IP protocol is used as a communication platform. The central server is a computer which is installed with fingerprint obtaining and identifying software and is provided with a database system. Furthermore the central server is connected with a fingerprint collector which is same to the fingerprint identifier terminal through data interface. The fingerprint can be respectively registered on the central server and the fingerprint identifier terminal, and can be transmitted to the corresponding terminal through cable network or wireless network. The remote fingerprint characteristic identification mode or local fingerprint characteristic identification mode is automatically switched according to the self-testing state of network in using. The invention provides the flexibility for registering user, storing and using the fingerprint formwork, and gives attention to the adaptivity in the conditions of cluster application and fault condition of network. Furthermore all data transmissions are processed through enciphering. The security of fingerprint identification technique based on the network communication is further increased.

Description

technical field [0001] The invention relates to a fingerprint recognition system and its realization method, in particular to a network distributed fingerprint recognition system based on network connection, fingerprint recognition chip and algorithm application and its realization method. Background technique [0002] In real life and work, personal identification technology used in hotels, building access control, bank securities account management, etc. has attracted more and more people's attention, and this level of attention has also increased with the improvement of people's culture and living standards. Constantly making new demands. In the past, tangible keys, IC cards or intangible passwords, etc., which were used to confirm the user's personal identity, all showed their shortcomings in the long-term application process. For example: keys are easy to be copied, and account passwords are difficult to remember and easy to lose and forget. Even if the IC card is comb...
