Background technology
In the modern society of fixing and development of Mobile Internet technology high speed development, information security demonstrates unprecedented importance.Identification and evaluation are the important prerequisites that guarantees security of system, in applications such as national security, ecommerce, E-Payment, safety inspections, all need identification accurately and evaluation.Current, personal identification is differentiated the main means such as ID card (as smart cards such as I.D., employee's card and deposit cards) and password that rely on, yet the use of ID card exists problems such as carrying inconvenience, easily loss, damage, accessing to your password faces password and passes into silence and the problems such as crack.According to statistics, the U.S. every year in the economic loss causing due to identity swindle aspect welfare granting, credit card trade, mobile phone and ATM transaction up to multi-million dollar.Therefore, so we are badly in need of a kind of convenient, effective, safe identity recognizing technology, to adapt to the needs of modern development in science and technology and social progress.
Biometrics identification technology is with its distinctive security for this reason, and reliability and validity etc. is more and more subject to people's attention, and starts to enter the every field of our social life.U.S. government has signed continuously three national security bills after September 11 attacks, requires to adopt biological identification technology.In June, 2003, International Civil Aviation Organization of the United Nations has announced the application planning of its biotechnology, will in individual passport, add biological characteristic as fingerprint, iris, face characteristic etc., and carries out personal authentication when immigration.
At present, all automatic recognition systems based on biological characteristic have substantially identical principle of work and the course of work.First be collecting sample, these samples can be facial image, sound, fingerprint etc.; Next is to carry out feature extraction, extracts some feature of sample, with certain algorithm, for it, distributes a feature code, and this code is stored into database.Finally when needs carry out identity authentication to someone, then will deposit the feature code of database in and identified person's feature matches with certain Feature Correspondence Algorithm, thereby find out its identity.In actual life, study more deeply, application has fingerprint, people's face, iris, hand-type, retina, vocal print and signature etc. more widely.
Wherein recognition of face is one of most important function of fundamental sum of having of human visual system, is the basis that the mankind exchange.People, by this visual performance identification identity each other, understand the other side's emotion and intention.Compare with other authentication identifying methods, the features such as recognition of face has directly, close friend, convenience, are widely used in authentication, criminal's identification, the fields such as scene surveillance.
Yet the thing claiming the identity of others fraudulently occurring in real life but still has generation.For example somewhere prison inmates is murdered the rear fingerprint with prison guard by prison guard and has been opened the gate in prison and sneaked away.And usurp by trojan horse the report that other people comprise that ID (identity number) card No., fingerprint, people's face information are committed a crime on the internet, happen occasionally.This wherein the defect of most critical be just for the method for authentication, only to use fixed biologically characteristic information at present, therefore after biological information is obtained by other people, a series of safety problems that its identification derived are just difficult to avoid.Although strengthen the encrypted work to identity characteristic information when people have also carried out being included in authentication accordingly, or adopt multi-modal biological characteristic recognition technology to gather the information such as people's face, fingerprint, palmmprint, iris to carry out authentication, but these methods or effect have much room for improvement or because the complexity of implementing is too high, be difficult to implementation simultaneously.For this reason, thereby the application proposes to build left or to the right based on binary coding people's face information with particular organisms feature is combined with people's face rotation information with codified biological characteristic by rotating face in the world first, therefore realize that static biological characteristic is encrypted and dynamic coding password combination and the security that improves authentication to contributing for information security and further developing of social civilization.
