Thus, the operators with different rights can execute different operations in different read regions by electronic tag, and the authentication course and operation are united in a terminal.
Description
Technical field
The invention belongs to the information electronic applications, specifically, relate to a kind of intelligent authentication terminal system and method based on radio-frequency (RF) identification and biometrics identification technology.
Technical background
How digitizing and recessivation that the one big feature in network information epoch is exactly an identity accurately identify a people's identity, and the protection information security is a crucial social concern that must solve the current information age.Credit number, account No., identification card number, network entry number, we may more and more be needed the password of memory stir to such an extent that upset in the life.We need a kind ofly need not remember these passwords and not worry the technology that own identity can't be assert, REID and biometrics identification technology just in time can address the above problem.
Radio-frequency (RF) identification (Radio Frequency Identification) common name RFID is a kind of non-contact automatic identification technology that utilizes radio-frequency technique to realize.It can realize the fast reading and writing to electronic tag, have that volume is little, shape is various, long service life, reusable, memory capacity big, can penetrate characteristics such as non-conductive material, and can realize the identification of multiple goal identification and moving target, tracking by can realizing article in the global range with combining of Internet technology and information shared.The RFID technology is used for industries such as logistics, manufacturing and service can significantly improve the management and the operational paradigm of enterprise, and reduces circulation cost; Be used for identification and location that rapid batch then can be realized in fields such as identification, asset management, and carry out the long-term follow management as required.The extensive propelling of further improving and using along with technology, the RFID cost of products will reduce rapidly, the industrial chain of its drive will become a rising high tech industrial colony, also will be to promoting the social informatization level, promote sustainable economic development, improve people's living standard, enhancing public security and national defense safety etc. produces wide influence based on the back-up environment construction of RFID technology.
Living things feature recognition (BIOMETRICS) technology be meant by computing machine utilize human body intrinsic physiological characteristic or behavioural characteristic carry out personal identification and identify.Physiological characteristic is inherent, mostly is geneogenous; Behavioural characteristic then is that custom makes so, mostly is posteriority.We are referred to as biological characteristic with physiology and behavioural characteristic.Biological characteristic commonly used comprises: fingerprint, palmmprint, iris, face picture, sound, person's handwriting etc.
The identity of differentiating the people is a very problem of difficulty, and traditional authentication identifying method is converted into the things of differentiating some sign personal identifications to this problem, and this comprises two aspects: 1) identify label article, such as key, certificate, atm card etc.; 2) identify label knowledge is such as username and password.In the system of some security requirement strictnesses, the two can be combined, require the user that atm card and password are provided simultaneously such as ATM.There is significant disadvantages in these traditional authentication identifying methods: the article that the individual has are lost easily or are forged, and individual's password is forgotten easily or misremembered.Even more serious is that real owner and the jactitator who obtains the identify label thing can't distinguish in these systems, in case other people have obtained these identify label things, just can have identical power.
Compare with traditional identity authentication means, have the following advantages based on the identity authentication technology of living things feature recognition: 1) anti-counterfeiting performance is good, is difficult for forging or stolen; 2) " carry ", do not have the problem of forgeing or losing.
Above dual mode has the incomparable characteristics of conventional authentication mode as new automatic identification technology.But, select wherein a kind of authentication mode merely for use, still there are some defectives.For example, single employing RFID technology authenticates can confirm whether be legal ID, can confirm to carry out instruction manipulation, simplify procedures, but can't assert whether be that the holder in due course operates, therefore for there being the people to hold the situation that effective RFID electronic tag authenticates, can't discern by back door; Living things feature recognition is based on user's biological information, and accurately whether decision person is legal operator, can't carry out the complicated order operation but can only authenticate.Accuracy in conjunction with multiple recognition method multiple authentication can greatly improve identity identifying and authenticating also will bring revolutionary change for the intelligent authentication field.
Summary of the invention
The objective of the invention is radio-frequency (RF) identification (RFID) technology is combined with living things feature recognition, realize the intelligent authentication terminal system of two kinds of authentication mode complementations, realize reliable executing instruction operations by RFID technology and biometrics identification technology simultaneously.
Implementation method of the present invention is to carry out double authentication by dual mode, after the operator who holds electronic tag sends instruction to the intelligent authentication terminal, at first its electronic tag of holding is carried out the unique coding of ground floor (ID) identification by rfid interrogator equipment, the information of obtaining authenticates, and under this ID, carry out the second layer and discern---living things feature recognition, comparison operator biological information, after double authentication affirmation identity, the instruction that the person of redoing sends.This system has guaranteed operator and institute's electronic tag of holding, and correspondence just can be by authentication one by one.If corresponding a plurality of radio frequency identification data is gathered antenna, then a plurality of antennas are represented different instruction respectively, these instructions correspond respectively to the zones of different of display screen, like this, operator with different rights can carry out different operations by electronic tag being placed difference read the zone, and verification process and operation are unified in a terminal.
Inventive principle
Intelligent authentication method based on radio-frequency (RF) identification and biometrics identification technology is: the operator holds the electronic tag that has authority information, after it sends operational order to intelligent terminal, entrained electronic tag is discerned by the antenna of radio-frequency identification reader/writer, radio-frequency recognition system finds out the authority information and the biological information of this label ID correspondence, by the living things feature recognition data collector operator is carried out living things feature recognition, this authentication by after the person's of redoing instruction of sending; The biological information that directly has legal holder in also can electronic tag, as fingerprint etc., radio-frequency identification reader/writer reads the biological information of storing in the electronic tag, the operator's biological information that collects with the living things feature recognition data collector relatively, authentication by after the person's of redoing instruction of sending.
Idiographic flow is as follows:
1, the operator holds in the authentication area that electronic tag enters intelligent terminal, and intelligent terminal is sent operational order.In radio frequency identification data is gathered the antenna identification range, rfid device reads electronic tag, interior ID number of electron gain label, according to ID number pairing authority information, the operator is carried out first re-authentication, extract the biological information of operator in the database simultaneously, and the living things feature recognition data collector is sent work order, drive the authentication beginning of second step.
2, the living things feature recognition data collector carries out living things feature recognition to the operator who holds electronic tag, and the biological information of operator in biological information of gathering and the database is compared.
If 3, comparison result coincide, represent that then this electronic tag is legal ID, the holder is legal operator, by authentication, enters for the 4th step; The result misfits and then refuses operator's instruction, waits for the next operation instruction.
