Description
Technical field
The present invention relates to the security fields of portable terminal, particularly relate to portable terminal and recognition methods thereof with recognition system.
Background technology
Along with the increased popularity of mobile e-business, mobile phone adds the authentication function trend that has been inevitable because only rely on mobile phone self with password and SIM card lock, more and more can not satisfy the requirement of people to the mobile phone security.Hidden danger on existing safely just because of mobile e-business is so many cell phone manufacturers also make an issue of in the mobile phone security in integrated various functions.The mobile phone fingerprint identification technology is a reasonable scheme.The machine master must write down the fingerprint of oneself in advance, utilizes mobile phone finger to be placed on sheet metal before paying then and makes identity validation, and transaction could be successfully.
CMOS (Complementary Metal-Oxide Semiconductor, complementary metal oxide semiconductor (CMOS)) sensor is a kind of imageing sensor that current quilt generally adopts, be to utilize light sensitive diode (photodiode) to carry out opto-electronic conversion, with image transitions is numerical data, in cmos sensor, each pixel all can be exported data with the mode of similar main memory circuit in abutting connection with an amplifier and A/D change-over circuit.Because cmos sensor adopts the most frequently used CMOS technology of general semiconductor circuit, can easily peripheral circuit (as AGC, CDS, Timing generator or DSP etc.) be integrated in the sensor chip, therefore can save the cost of peripheral chip; The image acquisition mode of cmos sensor is active, and the electric charge that light sensitive diode produced can directly amplify output by transistor, and in sum, cmos sensor then has the characteristics of low cost, low-power consumption and high degree of integration.Therefore, cmos sensor is responded to recognizer as retina, can gather, handle retinal images better, thereby obtained widespread use in the recognition technology of retinal images.
The retina scanning technology is the most ancient biological identification technology, in the thirties in 20th century, just drawn the theory of human eyeball rear portion vascular distribution uniqueness by research, further studies show that, even twin children, this vascular distribution also has uniqueness, except suffering from eye illness or serious brain trauma, and amphiblestroid version quite stable all in the middle of people's all one's life.Therefore, the security that utilizes retina to strengthen the portable terminal transaction also is a well imagination.In addition, although everyone fingerprint is all different, fingerprint can be along with the growth at age of people or healthy degree change yet and is changed, but should consider the appearance of some unexpected problems, if finger injuries can't be discerned, how to pay? the function whether substitute this moment? as antitheft door, it is used for antitheft, if but do not have key, it also can be with Subscriber Application Barring Lock outdoors.Relative fingerprint, more difficult damage, the stability and safety more of causing of retina.Retina is that some are positioned at the very tiny nerve in eyeball rear portion (an inch 1/50), it is that human eye is experienced light and information passed to the vitals of brain by optic nerve, it is similar a bit with the function of film, the vascular distribution that is used for bio-identification around neural retina, i.e. the farthest of retina four confluent monolayer cells.Retina scanning equipment will obtain retinal images, user's the eyes and the distance of recording device should be within half inches, and when recording device reads image, eyes must remain static, user's eyes are when watching the green light of a rotation attentively, and recording device can obtain 400 unique points from retina, with the fingerprint typing relatively, fingerprint can only provide 30 to 40 unique points to be used for typing, drawing template establishment and finish affirmation.As in the instructions of Chinese patent application (99124680.2), having introduced the retinal images recognition technology.This shows that the accuracy of system identification of the recording device of retina scanning technology is lower than 0.0001% (1,000,000/), some other biometric scan input technology also can reach 0.0001% accuracy of system identification (FAR) certainly, and the level of refusing false rate also can improve constantly.FAR refuses false rate and is meant that system refuses a user who has obtained authority improperly.To can't the typing rate, also can't obtain reliable statistical figure because seek out can't typing number be the very difficult thing of part, from experience, estimation can't the typing rate may be about 5-10%.With respect in mobile phone, setting startup password and SIM card lock, even the other technology of mobile phone fingerprint, guarantee that mobile phone is safer when paying, it have traditional mobile phone security system can't than like advantage.
