Abstract

The utility model relates to a finger vein plus CPU card dual mode identification system which adopts the finger vein identification technology. The finger vein plus CPU card dual mode identification system includes a high performance ARM board, a non-contact sensor which collects the deoxidized hemochrome in a human finger by infrared ray, a display screen which includes a touch screen, a terminal which is a wireless transmission device, and a related PC card issuing device. The CPU of the high performance ARM board is a low-power processor which is at least above ARM Cortex-A8 and has the floating point calculation function. The memory of the high performance ARM main board exceeds 512MB, and the high performance ARM main board is provided with a USB interface, a general GPIO interface, a general RS232 interface, an RS485 interface, a network interface, and a TTL interface. The high performance ARM main board is connected with the touch screen via the TTL interface, and is connected with a finger vein entrance guard via the USB interface. The card issuing device is a PC which is connected with a CPU card reader via the RS232 interface, so the corresponding finger vein information can be written into a CPU card, and the card issuing device shares an encrypted key with the terminal.

Description

Refer to vein+CPU card bimodulus recognition system

Technical field:

The utility model relates to a kind of finger vein+CPU card bimodulus recognition system, belongs to field of biological recognition.

Technical background:

The present recognition product of surface characteristics such as fingerprint palmmprint most importantly in the field of biological recognition, its shortcoming is that reliability is low, duplicates easily.And the present higher recognition technology of reliability---iris recognition technology, the one, owing to want the eye position near identification, acceptance level is lower; The 2nd, its price is too high, can't promote on a large scale.And the state-of-the-art technology that this product uses---refer to the vein identification technology scheme, be third generation biological identification technology, have vivo identification, internal feature, contactless and safe class advantages of higher, can effectively address the above problem.

The CPU card: also claim smart card, have microprocessor CPU, storage unit in the integrated circuit in the card, and chip operating system COS.The CPU card that COS is housed is equivalent to a microcomputer, not only has data storage function, has functions such as command process and data security protecting simultaneously.The CPU card is applicable to a plurality of fields such as finance, insurance, traffic police, government's industries, have user's space big (can store and refer to the vein data), reading speed fast, support characteristics such as one card for multiple uses, and through the authentication of People's Bank of China with the secret committee of merchant of country.

Summary of the invention:

The utility model provides a kind of finger vein+CPU card bimodulus recognition system; Utilization refers to vein identification technology, comprises contactless sensor, the display screen that has touch-screen, the terminal of radio transmitting device composition and the relevant PC card sender of the deoxidation hemochrome in high-performance ARM plate, the infrared ray collection human finger; The CPU of said high-performance ARM plate is at least the processor that has the low-power consumption of floating-point operation function more than the ARM Cortex-A8; Internal memory surpasses the ARM high performance motherboard of 512MB; Have USB interface, general GPIO interface, general RS232 and RS485 interface, network interface; And the TTL interface is connected to touching display screen, uses USB interface to be connected with finger vein gate inhibition.Card sender is the PC computer, is connected with the CPU card reader through RS232, can write the CPU card to the finger venous information of correspondence mutually, and uses identical cryptographic keys with the terminal.The utility model uses finger vein identification technology, has contactless identity and verifies, security performance is high; Easy to use, the ARM plate has high-performance, high reliability; Low energy consumption; Equipment is easy to safeguard, refers to that the vein data are stored on the CPU card after encrypting, not limited subscriber quantity and improve security performance.Simultaneously, the security performance of CPU card also be in the present IC-card preferably, increase the security of total system.

Fig. 2 is a PC card sender structural representation;

Embodiment:

At present; Domestic bank is no matter be debit card or credit card, because card such as is replicated at a variety of causes, the stolen incident of increasing fiscard occurred; If use refers to the mode that vein combines with the CPU card and just can stop the stolen incident of credit card basically, and is also extremely beneficial to the development of fiscard! Embodiment is that bank uses card sender, uses independent finger vein cryptographic keys, and personal user's distribution is had the CPU card that oneself refers to the vein data, referring to that the bank information of venous information with the individual combines.In use, the individual uses on the terminal, and the individual at first swipes the card, and reads in the terminal to information on the relevant card, lets go then, refers to vein identification, and the finance of can being correlated with has with that been operated.Owing to refer to that vein identification technology is difficult to duplicate, so this scheme can effectively be contained the generation of financial swindling, the safety coefficient of raising financial industry.
