Description
Technical field
The present invention relates to a kind of coding encrypting mode and application process of finger print information, particularly the fingerprints of the different fingers of 10 of people are encoded to build password with the decimal system, thereby realize the combination of the fixing biological characteristic of fingerprint and variable cipher and improve based on biometric identity identification or the security verified.
Background technology
The progress that enters 21st century science and technology makes the quick stepped into information epoch of class society, and the infotech of high speed development allows people's information interchange become convenient, quick, and work efficiency obtains huge lifting, and reinvents in all its bearings our society.Yet thing followed information security issue has been brought stern challenge as the development of stealing, falsely using or distorting also to our society of information.According to Federal Trade Commission, estimate, in recent years, the stolen or abuse of annual nearly 1,000 ten thousand American personal information, caused the loss of 5,000,000,000 dollars to consumer, and the loss of annual commercial undertaking is up to 48,000,000,000 dollars.Carrying out personal verification is the important channel ensuring information safety, and how to pick out rapidly and accurately personal identification, to guarantee information security and to safeguard civil order, has become modern society's important topic urgently to be resolved hurrily.
Traditional authentication identifying method mainly contains two kinds: the method based on knowledge and the method based on keepsake.Method based on knowledge is determined personal identification by checking " what you know ", and person to be verified uses the knowledge grasped to prove oneself identity as password, PIN (Personal Identification Number) (PIN) or password etc.Method based on keepsake is determined personal identification by checking " what you have ", and person to be verified uses held keepsake to prove oneself identity as certificate, seal or key etc.Obviously, above-mentioned two kinds of methods have obvious defect, " knowledge " exist easily forget or obscure, stolen by others or the problem such as crack, " keepsake " exists carry inconvenience, can loss or stolen, easily the problem such as be imitated.Therefore, the defect of traditional identity discrimination method makes it more and more be not suitable with scientific and technological development and social progress, and people have turned to sight the biological identification technology with not reproducible feature human body biological characteristics for this reason.So-called bio-identification, determines personal identification according to characteristics of human body." knowledge " used with conventional art is compared with " keepsake ", the characteristics of human body that biological identification technology adopts have be not afraid of forget, can not lose, be difficult to forge, irreplaceable, the outstanding advantages such as do not need additionally to carry.Therefore, bio-identification is not only safe and reliable, and easy to operate, has significant superiority.
Human body can be divided into two classes for the feature of bio-identification: physiological characteristic and behavioural characteristic.Physiological characteristic mainly contains: fingerprint, palm shape, iris, retina, people's face, facial thermal imagery etc.; Behavioural characteristic mainly contains: signature, voice, gait, keystroke etc.Research and experiment show, the above-mentioned feature of human body is all in the requirement that meets in varying degrees four fundamental propertys such as ubiquity, uniqueness, stability and collection property.Based on these features, people have been developed multiple biological identification technology, wherein apply wide or darker the having of research: fingerprint recognition, the identification of palm shape, iris recognition, retina identification, recognition of face, the identification of facial thermal imagery, sign identification, speech recognition etc.In various biological identification technologies, what fingerprint recognition and palm shape were identified is most widely used, and wherein fingerprint recognition has occupied absolute advantage especially, and the main biological recognition product on domestic and international market is substantially all based on fingerprint identification technology.
In fact fingerprint is a kind of more satisfactory biometric feature.Fingerprint is the lines image being distributed on human finger skin, multiple carinate lines, consists of.Study and show, fetus grew about seven months in parent, and its fingerprint is just completed into, and can not change all the life, unless the physical damnification that finger meets accident.Usually, biological tissue comprises that body surface observable characteristic is all by gene and the common decision of environment and impact, and fingerprint is exactly a kind of of body surface observable characteristic.For fingerprint, gene has determined its aggregated model feature, and the Skin Cell on finger tip starts differentiation phase, and the general characteristic of fingerprint starts to form gradually.In the process of Cell Differentiation, the position of fetus in uterus can constantly change, and its amnion liquid around also has different mobility status.Like this, the residing microenvironment of different finger is not identical.The fine structure of fingerprint determined by residing microenvironment, and the slight change of environment all can make the atomization of cell far from it.The mankind's gene is so to enrich, and the environment that forms fingerprint is again so to change variously, to such an extent as to is identical without any the fingerprint of two fingers.Even if there is the identical twin of same DNA (method that there is no is at present distinguished), do not have identical fingerprint yet, their fingerprint can be distinguished according to minutia completely.
In addition, in various biological recognition systems, the combination property aspect main is the most outstanding in security, ease for use and expense cost etc. for fingerprint recognition system, so it is once occurring having obtained being widely used of criminal investigation judicial domain.Along with the progress of computer technology, the ability complete independently fingerprint recognition computing that personal computer and some other microprocessor are as enough in DSP, ARM etc. has had.Meanwhile, along with the progress of sensor technology, the volume of fingerprint collecting equipment, power consumption and price have had significantly minimizing.This makes Automated Fingerprint Identification System be able to, to civil area development, can be widely used in all kinds of occasions that need personal identification such as message reference, electronic transaction, access control, attendance management and card management of the mechanisms of department such as government, bank, medical treatment, social security, school and company.And the widespread use of Automated Fingerprint Identification System also will contribute to reduce corrupt practice, restrain crime, avoid unnecessary social economy or personal property loss, also contribute to people to complete quickly and easily authentication simultaneously, increase work efficiency.From the situation in market, the market scale of biological identification technology is all increasing every year at a terrific speed, and the shared ratio of fingerprint recognition is keeping absolute advantage always.According to international bio identification group (IBG), estimate, fingerprint recognition surpasses 40% of whole biological identification technology market the shared market share in 2006.As can be seen here, Automated Fingerprint Identification System has wide application and market outlook, and the Social benefit and economic benefit that can bring can not be ignored.
Yet the safety problem of the stolen initiation of fixed biologically feature has limited the large-scale promotion application of biometrics identification technology in actual application.For example on the one hand by trojan horse, usurp the report that other people comprise that fingerprint, people's face information are committed a crime on the internet and happen occasionally, even occurred that prison inmates is murdered the rear fingerprint with prison guard unlatching gate, prison by prison guard and the felony of sneaking away.The people that make of these problems have proposed query to the reliability and safety of biometrics identification technology.Therefore be badly in need of now development and can effectively overcome in-problem new method in biometrics identification technology, system to promote better the raising of socioeconomic development and living standards of the people.
For this reason, the application proposes the fingerprint of 10 different fingers of people to encode to build password by the decimal system in the world first, thereby realize the combination of the fixing biological characteristic of fingerprint and variable cipher and improve the security based on biometric identity identification or checking, to contributing for information security and further developing of social civilization.
