Abstract
The utility model discloses a high-accuracy fingerprint identifier, comprising a microprocessor MCU, fingerprint acquisition sensor, a USB communication interface, a data security management module, a fingerprint comparison authentication module and a digital certificate authentication module, wherein the fingerprint acquisition sensor and the USB communication interface are respectively connected with the microprocessor MCU; the data security management module, the fingerprint comparison authentication module and the digital certificate authentication module are respectively connected with the microprocessor MCU; and the microprocessor MCU comprises a data encryption and decryption unit, a certificate storage and download unit, a key management unit, a digital signature management unit and a basic cryptographic algorithm acquiring unit. The time for comparing one group for the fingerprints high-accuracy fingerprint identifier is less than 1.5s so that the high-accuracy fingerprint identifier has quick identifying speed; for the high-accuracy fingerprint identifier, the probability for false identification is less than 0.001% and the probability for refusing identification is less than 0.01%, thus having high identification accuracy and high reliability; and the storage space is larger so that the data for 30 fingerprints can stored for one time.
Description
Technical field
The utility model relates to a kind of high precision Fingerprint Identification Unit.
Background technology
Fingerprint Identification Unit is widely used in work attendance, gate control system, concerning security matters resource management system, electronic government affairs system and numerous areas such as government, military organs, and it has advantages such as simple to operation and long service life.But there is following problem in existing Fingerprint Identification Unit: comparing two fingerprints usually needs the time about 2S, and recognition speed is slower; Occur that mistake is known and to refuse the probability of situation such as knowing still higher, lower, the poor reliability of accuracy of identification; Storage space is limited, and storable finger print information is less.
The utility model content
The purpose of the utility model is to solve the deficiency of existing Fingerprint Identification Unit, and a kind of novel high precision Fingerprint Identification Unit is provided, and overcoming two fingerprints of tional identification device comparison needs the time about 2S, and recognition speed is slower; Occur that mistake is known and to refuse the probability of situation such as knowing still higher, lower, the poor reliability of accuracy of identification; Storage space is limited, and storable finger print information is less.
The purpose of the utility model realizes through following technical scheme: the high precision Fingerprint Identification Unit; It comprises microprocessor MCU, fingerprint collecting sensor, usb communication interface, data safety management module, fingerprint comparison authentication module and digital certificate authentication module; The fingerprint collecting sensor is connected with microprocessor MCU respectively with the usb communication interface; Data safety management module, fingerprint comparison authentication module and digital certificate authentication module are connected with microprocessor MCU respectively, and described data safety management module comprises that data encrypting and deciphering unit, certificate store download unit, key management unit, digital signature administrative unit and basic cryptographic algorithm acquiring unit.
It also comprises a storer the utility model, and storer is connected with microprocessor MCU through internal bus.
The beneficial effect of the utility model is: compare one group of fingerprint required time and be no more than 1.5S, promoted the recognition speed of recognizer; The probability that the mistake knowledge occurs is less than 0.001%, and the probability that occurs refusing to know is less than 0.01%, and accuracy of identification improves greatly, has also increased the reliability of recognizer; Storage space is bigger, can 30 pieces of finger print datas of disposable storage.
