Abstract
The plastic support 14 of card of the present invention comprises the iron oxygen particle 11 of stochastic distribution, and is individualized for making card, signs and issues the plastic-substrates of authorities with magnetic induction detecting device scanning card, thereby reads the position p of iron oxygen particle.(ID, p), wherein " SIG " refers to the public key figure signature of any safety algorithm to the s=SIG of authorities' calculating subsequently, and ID is card owner's an identification details.At last, s and ID are recorded in the memory storage 13 of card.When this card was inserted into reader, the parts of plastics of reader scanning card also read branch characteristic p.Memory storage from card obtains ID and s and reader inspection s (ID, real signature p) subsequently.
Description
The present invention relates to the recognition device that to forge, recognition device reader and recognition methods.
Known multiple plastic clip now, storage card is cheap and comprise memory storage, but easily is forged and duplicates.Smart card also comprises microprocessor and can be used to the purpose of password, use and banker's invoice as the payment TV, but your usefulness it wants many.
The purpose of this invention is to provide cheap and storage card that can not forge.
Storage card of the present invention is characterised in that it in case signed and issued by relevant department, just may be replicated hardly.This is stuck in the smart card that is better than on the cost with microprocessor, because needn't need memory protection device and computing power to realize authenticity again.
The method for making of neocaine and the difference of standard card are that small metal or ferrite particle (as steel marble) are mixed mutually with plastic paste, and the plastic support of card is done with this potpourri.
Thereby each card of making comprises the different random distribution patterns of particle.The stochastic distribution of this particle is considered to be in the manufacturing process uncontrollable or influence.
Each reader is provided with the magnetic induction detecting device, and the latter makes it can read the distribution number p of particle; Also provide chip reader, to read the memory storage of card.
For individualized, sign and issue authorities and take the following step card:
1. set up holder's identification details ID;
2. take out a card and read its random pattern p;
3. calculate s=SIG(ID, p);
4. in the memory storage of card, write down s and ID;
5. give the user card.
Here " SIG " represents the public key figure signature of any safety.Memory storage is electronic protection preferably.
When card is inserted the affirmation reader, reader will scan it and the stochastic distribution of particle will be converted to several p.Subsequently, confirm that reader reads s and ID from the memory storage of card, and by carrying out SIG
-1Check s determines it is (ID, p) signature.
On principle, the recognition device of can not forging of the present invention comprises memory storage and a zone, and the detectable primitive in its position has distribution at random in the latter; This distribution usable levels p represents, thereby make that the position of described primitive is uncontrollable when producing, but can in reading device, detect and measure, and in described memory storage, store identity data ID and public key figure signature s=SIG(ID, data s p) at least.
Another purpose of the present invention provides a kind of reader that is used for this recognition device.
On principle, recognition device reader of the present invention comprises: pick-up unit, especially magnetic induction reader are used for determining the position of described primitive, thereby produce described distribution value p; Reading device is used for described identity data ID and the data s that has the described memory storage of described recognition device at least.
Another object of the present invention provides a kind of recognition methods that has utilized recognition device of the present invention and reader.
On principle, method of the present invention has adopted recognition device and recognition device reader, and comprises the following steps:
-collection user's identification details ID;
-calculating s=SIG(ID, p), wherein SIG is public key figure signature scheme function;
-s and ID are existed in the described memory storage (13) of described recognition device.
And comprise following identification step:
-read described recognition device with described recognition device reader, thus produce described distribution value p and read s and ID at least from described memory storage (13);
-by carrying out corresponding contrary public key figure signature function S IF
-1, check that s really is the p that connects together and the signature of ID.
Most preferred embodiment of the present invention is described in the time of in conjunction with the accompanying drawings, in the accompanying drawings:
Fig. 1 is the structure of storage card of the present invention;
Fig. 2 is the structure that is used for the reader of the present invention of storage card.
In Fig. 1, iron oxygen distribution of particles standard shape, embedding is arranged in the plastic support thing 14 of storage card.This card comprises chip 13, can be for example with non-contacting mode swap data in corresponding reader by it.Both sides at card are provided with electron scanning sync mark 12.
In Fig. 2, card is inserted into reader (scanner).This reader comprises the electromagnetic scanning unit 22 that is used to produce distribution value p, for example a photoscanning synchronous head 23 and be used for identity data ID at least and have the reading device (intelligent card chip reader) of data s of the storer of chip 13.ID, s, distribution value p and possible password w calculate in microprocessor 21; But the part of latter's reading device.
The signature that example is Rabin of figure notation figure, wherein n is the RSA modulus, and s is by s=SIG(m)=m
1/2Mod n definition.Corresponding affirmation is by checking S
2Mod n=m carries out.
Also can select to improve basic signature by comprising user password w.In the case, sign and issue one the card and confirm that the process of its correctness is:
1. set up holder's identification details ID;
2. get a card and read its random pattern p;
3. decision is the password w of user's appointment.
4. calculate s=SIG(ID, p, w).
5. in the memory storage of card, write down s and ID.
6. give the user card and w.
For confirming the correct of this card, confirm that reader will resemble to work the front, but will ask the user to key in w.
The SIG scheme is one of following method:
The figure notation figure of-Rabin;
-RSA Algorithm, Rivest, Shamir, Aclelman, " A met hod for obtaining digital signatures and public-key cryptosystems ", Commumications of the ACM, Vol21, No2, pp120-126,1978);
-data markers figure standard (DSS);
-ELG，“A public-key crysptosystem and a signature scheme based on the discrete logarithm”，IEEE Transactions on Infovmation Theory，Vol.31，No.4，pp.469-472，1985;

For making iron particulate scan synchronously (no matter the insertion speed of card how), can be on card (as at its boundary) make machinery or optical markings sequence.Mark is preferably detected with optical means by reader, and triggers the scanning of plastics by the road.Mark also can be based on Electromagnetic Testing Technology, correspondingly trigger sweep again.
Except plastic material, the material that also can adopt other to allow the distribution to particle to detect.Equally, except magnetic-particle, also can adopt other primitives, as long as its distribution can be detected and not be allowed to duplicate.
Except that card, also can adopt the device or the shape of other types, thereby reader is also wanted corresponding change.
Identification also refers to differentiate.
