Description
Technical field
The present invention relates to safety cabinet security technology area, particularly based on safe system and the key thereof of ultrasonic imaging and recognition technology.
Background technology
Along with socioeconomic fast development, people take in raising, and the social life of people is day by day frequent, and frequency of going out is high, the time is long, how to ensure that property safety has become people's question of common concern, safety cabinet becomes the safety sustenance part that people deposit valuables and classified papers.In safety cabinet cabinet series products more common on the market, the password of common employing has: mechanical, electrical type, bio-identification class etc.
The feature of mechanical cipher safe is that password have employed full mechanical, and properties of product are very reliable and stable, product all the life without the need to any maintenance, so cost is low.And shortcoming must be opened according to fixing pattern when being and using, so the comparatively loaded down with trivial details and change of password of operation needs professional to operate, password can not be specified.According to the feature of machine insurance cabinet, machine insurance cabinet is applicable to bank, and family etc. do not need the occasion changing password to use.
Electrical type cipher safe is the main force in current safety cabinet market, and market share is the highest.Traditional electrical type cipher safe adopts keyboard entry type, and the input of password generally adopts keypad, and keycap has stationary digital and the difference of on-fixed numeral.Password needs memory, requires to prevent from giving away secrets with stolen.Along with the development of computer technology, electrical type cipher safe develops a series of new-type electronic recognition technology, and common electronic recognition technology has: bar-code identification, magnetic card identification, IC-card identification, radio-frequency (RF) identification.Modern electronic recognition technology has that cost is lower, simple to operate, system intelligent and password arrange the advantages such as change is flexible.But the poor anti jamming capability of modern electronic recognition technology, magnetic card is easily subject to high-intensity magnetic field interference, and IC-card is easily by electrostatic interference, and rfid card holds easy electromagnetic wave interference.
Emerging bio-identification safety cabinet life is combined with high-tech means such as light, sound, biology sensor and biostatistics principles closely by computing machine, and the physiological property (as fingerprint, face picture, iris etc.) utilizing human body intrinsic and behavioural characteristic (as person's handwriting, sound etc.) carry out personal identification qualification.Biological identification technology has more safety than traditional identity identifying method, maintains secrecy and convenience.Biometrics identification technology tool is not easily forgotten, anti-counterfeiting performance is good, not easily forge or stolen, the advantage such as carry with and can use whenever and wherever possible.Bio-identification safety cabinet generally adopts fingerprint recognition, iris recognition and people face to identify:
(1) fingerprint recognition is the most ancient biometrics identification technology, in a lot of field, be obtained for successful application.Fingerprint recognition mainly according to the information such as lines, minutia of somatic fingerprint to operation or carried out identity authentication by operator.Everyone has, and oneself is unique, constant fingerprint, fingerprint recognition is applied on safety cabinet, strong security, easy-to-use.
(2) people face recognition technology is uniqueness feature according to the face feature of people and the individual identification of carrying out and confirmation technology.The uniqueness of the facial characteristics of people, can be embodied on a certain one organ or position on the face, the more important thing is can position between these single features, distance, angle, quantity, the mutual relationship such as shape and pattern is embodied, and these facial characteristics all have certain stability.
(3) iris recognition is that current application facilitates and accurate biological identification technology the most.Iris is a ring-type viewable portion between pupil and sclera, has lifelong unchangeability and otherness, and compared with other biological characteristic, iris recognition has the advantages such as high uniqueness, high stability, antifalsification are good, usability, easy analysis.
Technical characterstic in conjunction with the safety cabinet market demand and existing safety cabinet technology is now analyzed, and existing safety cabinet technology has the following disadvantages:
(1) mechanical code safety cabinet, complex operation, ease for use is poor, and number of password is few.Mechanical code safety cabinet development time is the longest, and breaking techniques is the most ripe, poor stability.
(2) electronic password safe, electronic cipher interference free performance is poor, and unlocking pin is easily replicated or cracks, and there is potential safety hazard.
(3) humidity of fingerprint recognition opponent requires relatively tighter, and easily fingerprint is stayed smooth article surface in daily life, and fingerprint trace existence is used to the possibility copying fingerprint, easily reveals or is forged.
(4) iris recognition and people face identify all have the advantage that discrimination is high, untouchable, fraud is difficult, but recognizer is complicated, and equipment cost is expensive, is not suitable for general user.
Ultrasonic imaging recognition technology is a kind of new technology attracted people's attention, and has been widely used in modern Dynamic Non-Destruction Measurement.Ultrasound wave can detect the defect in object, and determines its position, size, shape and character.Hyperacoustic dissemination is relevant with quality to the mechanical property of material in the material, and the ultrasonoscopy of object can provide visual information intuitively.The ultimate principle of ultrasonic imaging identification is, comparatively strong reflection can be there is by during different acoustic impedance medium interface in ultrasound wave, and the larger reflection of difference between medium will be larger, penetration power is gone out to an object emission strong, can the ultrasound wave of rectilinear propagation, then the ultrasound wave reflected is received and the hyperacoustic priority reflected according to these, the situations such as amplitude just can judge the size of the various media contained in this tissue, the information such as the contrast difference degree between distribution situation and various medium, the hyperacoustic priority wherein reflected can reflect the distance of reflecting interface from searching surface, amplitude then can reflect the size of medium, the characteristics such as contrast difference degree.
Summary of the invention
