Description
Technical field
The present invention relates to the coding encrypting mode and its application process of a kind of human ear information, particularly the ear of people or so two is led to
Cross binary mode to be encoded to build password, carried so as to realize biological characteristic and the combination of variable cipher that human ear fixes
The security that height is recognized or verified based on biometric identity.
Background technology
Progress into 21st century science and technology causes class society quick stepped into information epoch, the information technology of high speed development
The information interchange of people is allowed to become more convenient, fast, operating efficiency obtains huge lifting, and reinvents us in all its bearings
Society.However, the development band stolen, falsely use or distort also to our societies of thing followed information security issue such as information
Stern challenge is carried out.Estimate according to Federal Trade Commission, in recent years, about 10,000,000 American individual every year
Information is stolen or abuses, and 5,000,000,000 dollars of loss is caused to consumer, and the loss of annual commercial undertaking is then up to 48,000,000,000 U.S.s
Unit.It is the important channel for ensuring information safety to carry out personal verification, how personal identification is rapidly and accurately identified, with true
Protect information security and safeguard civil order, it has also become modern society's important topic urgently to be resolved hurrily.
Traditional authentication identifying method mainly has two kinds：Knowledge based engineering method and the method based on keepsake.Knowledge based
Method determine personal identification by checking " what you know ", i.e., person to be verified uses grasped knowledge such as password, individual
People's identification code (PIN) or password etc. prove the identity of oneself.Method based on keepsake then by check " what you possess " come
Determine personal identification, i.e., person to be verified proves the identity of oneself using the keepsake held such as certificate, seal or key etc..It is aobvious
So, above two method has obvious defect, and " knowledge " exists easily to forget or obscure, be stolen by others or crack etc. and asks
Topic, " keepsake " then there are problems that it is inconvenient to carry, can lose or be stolen, easily.Therefore, traditional identity discrimination method
Defect causes its development for being increasingly not suitable with science and technology and the progress of society, is that this people has turned to sight with not reproducible
The biological identification technology of feature human body biological characteristics.So-called bio-identification, i.e., determine personal identification according to characteristics of human body.With biography
" knowledge " that system technology is used is compared with " keepsake ", and the characteristics of human body that biological identification technology is used has and is not afraid of forgetting, no
Can lose, be difficult to forge, it is irreplaceable, be not required to the outstanding advantages such as extra carrying.Therefore, bio-identification is not only safe and reliable, and
And it is easy to operate, with significant superiority.
The feature that human body is used for bio-identification can be divided into two classes：Physiological characteristic and behavioural characteristic.Physiological characteristic mainly has：
Fingerprint, palm shape, iris, retina, face, facial thermal imagery etc.；Behavioural characteristic mainly has：Signature, voice, gait, keystroke etc..Grind
Study carefully and experiment shows, the features described above of human body all meets generality, uniqueness, stability and collection property etc. to varying degrees
Four requirements of fundamental property.Based on these features, people have developed various biological identification technologies, wherein application is relatively wide or studies
Deeper has：Fingerprint recognition, the identification of palm shape, iris recognition, retina identification, recognition of face, facial thermal imagery identification, human ear are known
Not, signature recognition, speech recognition etc..
Ear recognition is a kind of emerging biometrics identification technology recent years, and human ear possesses abundant physical arrangement,
With generality, uniqueness and persistence.Compare with recognition of face, age, facial expression, cosmetics and Hu are not received in ear recognition
The influence of palpus, while also with IMAQ conveniently, advantage susceptible to user acceptance, the solid colour of human ear, picture size is small,
Data processing amount is also smaller.Therefore its application in authentication system is just paid high attention to by people.
But biological characteristic is fixed in actual application be stolen the safety problem of initiation and limit living things feature recognition
The large-scale promotion application of technology.For example on the one hand on the internet by trojan horse usurp other people including ID card No.,
Fingerprint, face information and the report committed a crime happens occasionally, or even there occurs prison inmates after prison guard is murdered with the fingerprint of prison guard
The felony opened prison gate and sneak away.These problems generation cause people to biometrics identification technology can
Query is proposed by property and security.There is problem during biometrics identification technology can effectively be overcome in therefore urgent need development now
New method, system advantageously promoting the development of social economy and the raising of living standards of the people.
Therefore, the application propose first in the world by people difference ear profile encoded by binary system it is close to build
Code, improved so as to realize the combination of biological characteristic and variable cipher that human ear profile is fixed based on biometric identity identification or
The security of person's checking, contributes to the further development for information security and social civilization.
The content of the invention
Technical problem：Encoded by binary system it is an object of the invention to provide a kind of profile information by people's difference ear
To build password, so as to realize that the biological characteristic that human ear profile is fixed exists with the combination of variable cipher to play biological information
Convenience in authentication, it is effective the advantages of and coding encrypting dynamic advantage, with ensure authentication conveniently, safely with can
Lean on.
Technical scheme：The present invention is in the world first encoded with structure the profile information of people's difference ear by binary system
Password is built, fixed human ear profile biological characteristic is believed so as to realize the combination of biological characteristic and variable cipher that human ear is fixed
Ceasing the password built from variable different ear profile informations coding and combining is used for authentication, so as to play biological information knowledge
Not with the advantage of password identification, to advance the further development and application of identity validation technology.
The coding encrypting method of human ear information of the invention, set first people or so ear put in order and according to 0-1 i.e.
Binary system is encoded, then visit ear by obtain human ear profile information coding based on password segment, repeat visit ear process with
