Description
Technical field
The present invention relates to a kind of intelligent fingerprint recognition device, more specifically relate to a kind of device in conjunction with physiological parameter identification finger print information, belong to technical field of data recognition.
Background technology
Fingerprint identification technology is widely used in the fields such as safety door inhibition, attendance, examination identification, safe, USB flash disk data encryption.Everyone fingerprint is different on pattern, breakpoint and point of crossing, presents uniqueness and constant throughout one's life.Accordingly, the fingerprint of someone and the finger print data preserved in advance are compared, just can verify the true identity of this person, Here it is fingerprint identification technology.Fingerprint image is made up of the sunk part (being called valley line) had between the streakline (being called crestal line) of one fixed width and trend and streakline.
Optical finger print recognition technology is placed on optical mirror slip by finger, point under built-in light source irradiates, be incident upon on charge-coupled device (CCD) with prism, so formed crestal line be black, valley line in white digitized, can by many gray-scale fingerprint images of fingerprint equipment algorithm process.Because light can not transdermal top layer, so optical finger print machine can only scan the top layer of finger skin, skin corium can not be goed deep into.
Semiconductor silicon capacitive sensing technology is using the pole plate of sensor as electric capacity, points as another pole plate, utilizes the ridge and paddy of pointing streakline relative to the capacitance difference between level and smooth silicon sensor, forms 8 gray level images.Electronic signal will pass the surface of finger and dead property skin layer, and the skin corium of through finger skin, directly reads fingerprint pattern, reach living body finger print identification.Security is higher comparatively speaking.
Ultrasonic fingerprint collection is then the ability utilizing ultrasound wave to have penetrable material, and produces the principle of the echo varied in size with the difference of material, utilizes skin and air for the difference of sound impedance, just can distinguish the position at fingerprint ridge and paddy place.Ultrasonic technology precision is high, but its acquisition time is long, and expensive, also can not accomplish living body finger print identification, so use rareness at present.
Go through the development of decades, fingerprint identification technology, from previous optical recognition, to temperature difference induction identification technology, to semiconductor silicon capacitive sensing technology, then to more advanced ultrasonic technology, all also exists the security risk be cracked.The conventional fingerprint recognition device of prior art only identifies fingerprint pattern to be measured, contrasts with the fingerprint pattern recorded in system, if judge consistent, judges that this fingerprint pattern is verified.Now commercially there is special imitated fingerprint film technology.By copying the fingerprint pattern of experimenter, fingerprint can be copied on similar silica gel material, because the fingerprint copied is identical with experimenter's fingerprint, equally also can obtain being verified of conventional fingerprint recognition device.As long as imitated fingerprint film, just can cheat conventional fingerprint recognition device on tester's fingertip.Heilungkiang as occurred in September, 2,014 3 Newgate saints that lengthen the life escape from prison case, criminal escaping from prison be exactly cut down prison guard finger to verify optical finger print machine, and then open prison access control.And for example recent each medium exposes, and Taobao spends about 100 yuan just can buy a silica gel finger print, and in order to imitated fingerprint, can easily pass through the checking of optical finger print machine, working clan is used for for beating fingerprint attendance.The Henan Province's college entrance examination also having occur for 2014 impersonates event, impersonate examinee and have the imitated fingerprint film really need participating in college entrance examination examinee, can, smoothly by this pass of fingerprint recognition, the outpost of the tax office originally intending to utilize the feature of somatic fingerprint uniqueness to carry out authentication be performed practically no function.
Summary of the invention
The technical problems to be solved in the utility model is to avoid the cut next finger of intelligent fingerprint recognition device or be imitated fingerprint film cheating the risk passed through.For overcoming the above problems, the utility model application provides a kind of intelligent fingerprint recognition device, and the basis of conventional fingerprint identification adds live physiological parameter detecting.
The intelligent fingerprint recognition device of the utility model application comprises intelligent fingerprint identification control unit, fingerprint identification module, physio-parameter detection module and power supply unit.Intelligent fingerprint identification control unit is connected with fingerprint identification module, physio-parameter detection module, and fingerprint identification module is in order to carry out conventional fingerprint recognition, and physio-parameter detection module, in order to detect live physiological parameter, comprises blood oxygen, heart rate etc.Physio-parameter detection module can be optical reflection type heart rate detection module, optical reflection type blood oxygen detection module, Light Transmission heart rate detection module, Light Transmission blood oxygen detection module, one of them is individual or multiple for cardiogram mode heart rate detection module (adopting ECG current system).
The beneficial effect of the utility model application is, the identification of heart rate value or oximetry value was first carried out before carrying out conventional fingerprint identification, the finger that cuts or imitated fingerprint film can be avoided to be verified, effectively to prevent fingerprint recognition from judging by accident, improve the security of fingerprint identification device.In addition, due to the physiological parameter of Different Individual, there is some difference, if forger differs comparatively large with the physiological parameter of actual individual, then can not be verified, to a certain degree can hit the idea of leaving things to chance acted as fraudulent substitute for a person.Further, synchronously physio-parameter detection can be done when carrying out fingerprint recognition, in order to the health status that assessment test is individual.
