Description
Technical field
The utility model belongs to electronic information technical field, is specifically related to a kind of radio-frequency intelligent anti-fake certificate.
Background technology
The tradition certificate has permanent use history, is applied to all trades and professions.Certificate provides two kinds of basic functions: a kind of is to differentiate, promptly to the proof of identification and the description of main body that certificate depends on; Another kind is false proof, and antiforge function is the realization prerequisite of identification function.
The development of society, the progress of infotech are had higher requirement to the function of traditional certificate: the exhaustivity of data message and accuracy need to strengthen, and the certificate false proof ability is anxious to be waited to improve, and data message need be by quick, accurate, safe read-write.Two kinds of basic functions of tradition certificate depend on printing technology to a great extent, and this has just limited the read-write mode of certificate data message and has write indegree, and the forgery phenomenon of certificate also is difficult to avoid.
A solution is the card-type credentials of embedded IC intelligent chip, and the bearing capacity of data message and read-write mode have had good improvement; But the traditional appearance of certificate is destroyed, can't bind into book form, has cut down greatly and has looked the read message bearing capacity, thereby the data message read-write mode of certificate is restricted to the machine read-write.
Another kind of solution is the magnetic stripe certificate, and the traditional appearance of certificate is kept, but the read-write mode of magnetic stripe data information is single, and read or write speed is slow, and magnetic strip information easily goes to pot, and environment for use requires also relatively harsher.
At this situation, the utility model is applied to microelectric technique and radio-frequency technique in the middle of the certificate making, above two kinds of problems that scheme faced have well been solved: the traditional appearance that keeps certificate, original function is not lost, quick and easy read-write mode is provided simultaneously, the data information memory amount is greatly improved, and antiforge function has also had essential change.
The utility model content
The utility model provides a kind of radio frequency anti-fake certificate, modern cryptographic techniques such as utilization microelectric technique, radio-frequency technique and digital signature, simultaneously can selectively merge biological identification technologies such as fingerprint characteristic identification, iris recognition, solve traditional certificate in the problem that is faced aspect relativity of information and false proof two, remedied the deficiency of card-type credentials, magnetic stripe certificate.
The technical solution adopted in the utility model is:
1. use art paper encapsulation intelligent RF chip and radio-frequency antenna;
2. choose inside and outside two-layer certificate strip of paper used for sealing according to practical application: internal layer generally is used to print the information such as identity of holder, adopts good paper material; Skin is exposed to outside the certificate, is printed with flag informations such as certificate purposes simultaneously, can select to have the colloidal materials of functions such as anticorrosion, waterproof;
3. the art paper that will be packaged with intelligent RF chip and radio-frequency antenna is embedded in the middle of the inside and outside two-layer certificate strip of paper used for sealing, and the certificate strip of paper used for sealing is carried out hot rolling and plastotype.
Art paper has good tack and pliability, guarantees that intelligent RF chip and radio-frequency antenna are firmly encapsulated, and with the material of multiple certificate strip of paper used for sealing the good binding performance is arranged also.The use of art paper just in conjunction with the characteristic of the contactless read-write of intelligent RF chip, makes the certificate that embeds radio frequency chip and radio-frequency antenna have good engineering characteristics such as dustproof, waterproof, anticorrosion.
The inside and outside two-layer strip of paper used for sealing material of certificate should be chosen in conjunction with the environment for use and the term of life of reality.Non-contacting electromagnetic coupled mode is taked in the message exchange of radio frequency chip and frequency read/write, the stock size specification of certificate strip of paper used for sealing does not influence data message access in the radio frequency chip, thereby can with the art paper that is packaged with radio frequency chip tight be embedded into certificate inside and outside two-layer between, the material of inside and outside two-layer strip of paper used for sealing and thickness then also can become with need.
The selection of the selection of radio-frequency antenna, winding mode and intelligent RF chip relative position has fundamental influence to the outward appearance and the use of certificate.Certificate allows the bending of certain angle, but does not allow usually to fold, and adopts mode of printing that radio-frequency antenna is fixed on the art paper, and it is minimum that the thickness of radio-frequency antenna is dropped to, and also provides good basis for art paper with combining of certificate strip of paper used for sealing.Radio-frequency antenna is taked the winding mode of round rectangle, and the scope of the radio-frequency antenna electromagnetic coupled of increasing and frequency read/write reduces the coupling blind spot.In order to reduce the bending probability of radio frequency chip and radio-frequency antenna junction, radio frequency chip should be fixed on the nearer position of distance certificate cord; In addition, the thickness of common certificate can not influence the read-write of radio frequency chip, can select art paper is embedded in the front cover or the back cover of certificate according to actual conditions.
Intelligent RF chip is the basis of the utility model information stores and information security, be used for storing data information and the digital anti-counterfeiting function is provided, its memory data output can reach tens of K Bytes, data communication safety is guaranteed by the bidirectional authentication mechanism of frequency read/write and intelligent RF chip, radio frequency chip adopts fusing mechanism, has prevented malicious attack or detection.In addition, effective read-write number of times of radio frequency chip is mostly more than 100,000 times, and tenure of use, like this, the data in the radio frequency chip can repeatedly be changed, and have fundamentally changed the wretched insufficiency that traditional certificate is showed in this respect more than 10 years.
Radio frequency chip has unique read-only hardware sequence number, and this sequence number as unique sign of certificate, is carried out digital signature in conjunction with the data message of chip stored, is used to prevent the bootlegging and the pseudo-system of certificate, has fundamentally solved the anti-pseudo problem of certificate; Unique sequence number also can be used as the foundation of certificate personal managements such as certificate is reported the loss, blacklist operation.
Radio-frequency antenna is responsible for the radio-frequency communication of intelligent RF chip and frequency read/write.The application of radio-frequency technique makes the I/O operation of intelligent RF chip adopt non-contacting mode, and the operation energy of radio frequency chip is obtained by the read-write antenna electromagnetic coupled of radio-frequency antenna that is attached thereto and frequency read/write.
Frequency read/write is connected to computing machine, by computer control, read and write fingerprint characteristic, the iris feature digital information that is stored in intelligent RF chip in non-contacting mode, can simplify the read-write process of certificate information, carry out authentication efficiently, accelerated information flow simultaneously.More frequency read/write can be embedded in the middle of the handheld device such as PDA, realize mobile management the radio frequency certificate.
