Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention can be used in numerous general or special purpose calculation element environment or the configuration.For example: mobile phone, personal computer, server computer, handheld device or portable set, plate equipment, multiprocessor device, comprise distributed computing environment of above any device or equipment or the like.
Referring to Fig. 1, be the flow chart of steps of the method for a kind of article anti-counterfeit of the embodiment of the invention one, this method comprises:
Step S101: obtain the summary info for the treatment of false proof article;
Wherein, treat that false proof article can be extensive stock in certificate, bill or the market etc., as, treat that false proof article can be various certificates such as I.D., academic certificate, honorary certificate or various qualification certificates; Treat that false proof article also can be bills such as various ticket, admission ticket, various invoices.
The summary info for the treatment of false proof article is: treat the image information of false proof article, the Word message for the treatment of to show on the false proof article, recommended information etc.Can also comprise the information such as valid period for the treatment of false proof article.Certainly can also in summary info, increase other information for the treatment of false proof article according to actual needs.
For example, be example with the certificate, the summary info that obtains certificate can be the image information of certificate, can react content displayed on the certificate more intuitively like this, or additional clause word content summary.The relevant information that can also comprise the issuing organization and the issuing organization of certificate certainly, or the information such as date of expiration of certificate.
Wherein, the mode of obtaining the summary info for the treatment of false proof article can have multiple, can for: adopt and treat false proof article and take pictures, and from photo, extract the mode of summary info; Perhaps, for the summary info of forms such as literal, also can adopt manual entry is become e-file, from e-file, extract summary info again, can certainly adopt above dual mode combination is removed to obtain summary info, perhaps adopt other modes, enumerate no longer one by one here.
Step S102: utilize first private key that presets that described summary info is encrypted and generate first signature file;
By first private key that presets the summary info for the treatment of false proof article that gets access to is encrypted, to obtain first signature file corresponding with summary info.Have only by first PKI corresponding and could be decrypted the summary info that obtains treating false proof article this first signature file with this first private key.
Step S103: generate security code according to described first signature file and the public key information corresponding, so that described security code is presented at described treating on the false proof article with described first private key.
According to first signature file that obtains after will Summary file encrypting and the public key information corresponding, and encode and wait processing can generate the security code of correspondence with first private key.Then, security code can be presented at by modes such as printing, stickups and treat false proof article,, can realize verifying the purpose of the true and false of existing article by this security code by corresponding proving program.
Process by the security code checking article genuine-fake, need deciphering first signature file to obtain the summary info of article, therefore need to comprise in the security code public key information of the first private key correspondence, so that decipher first signature file according to the public key information of the first private key correspondence.Wherein, the public key information of the first private key correspondence can be the generation parameter of first PKI of the first private key correspondence.When checking article genuine-fake, according to the image information acquisition of the security code on the article to first signature file and the relevant generation parameter information of first PKI, utilize this generation parameter information to generate first PKI then, utilize first PKI to decipher first signature file again.
Certainly, the public key information of the first private key correspondence also can be first PKI of the first private key correspondence.In this case, during checking article genuine-fake, only need to first PKI and first signature file, just can directly be deciphered first signature file with first PKI according to the image information acquisition of the security code on the article.
Wherein, first PKI is the key corresponding with first private key, have only by this first public key information and just can decipher first signature file, thereby first signature file is reduced to the summary info for the treatment of false proof article, so that in the proof procedure, compare by this summary info and article, distinguish article genuine-fake.
The security code that the embodiment of the invention generates can be one dimension sign indicating number (bar code), two-dimension code, plays the effect of storing summary info and gets final product so long as can preserve.It is big to consider that two-dimension code has an information memory capacity, can represent multiple information such as Chinese character and image, is applicable to the characteristics of printing or sticking on article surface, can preferentially select two-dimension code as security code.Certainly, specifically select which kind of security code to determine as required.As, summary info is the recommended information for the treatment of false proof article of typing, is example with the certificate, summary info is the synopsis that comprises in the certificate, the signature file of the synopsis correspondence after encrypting can be generated the one dimension sign indicating number.
False proof to article comes down to false proof to the article fabricator, therefore, the most important thing is how to guarantee the authenticity of fabricator's identity, therefore, needs the arbitration of a third-party institution.That is to say, in the process that security code generates, should be able to embody the arbitrated procedure of the third-party institution, to guarantee the reliability of article fabricator or issuer, the mode that embodies the process of this arbitration in security code can have multiple, for example, wherein a kind of mode can for: by third party's false-proof mechanism according to the identity information for the treatment of false proof article issuer, determine and treat the corresponding unique PKI of false proof article issuer, and utilize the specific authorisation software program of third party's false-proof mechanism, by some algorithms this PKI is converted into first private key.
That is to say that first private key that presets among the step S102 is: third party's false-proof mechanism licenses to the private key for the treatment of false proof article issuer.Because first private key is after third party's false-proof mechanism is treated false proof article issuer identity validation, license to the private key with uniqueness and non-reproduction of this article issuer, therefore by this first encrypted private key, first signature file, and the process that finally obtains security code has just embodied the identity validation process that third party's false-proof mechanism is treated false proof article issuer.
Wherein, treat false proof article issuer, be meant the producer, fabricator or the issuer etc. for the treatment of false proof article.As, when treating that false proof article are various certificate, the issuer that treats false proof article is meant the Notified Body of certificate; When treating that false proof article are commodity, treat that the issuer of false proof article is meant, the production of commodity, fabricator.
When first private key that presets is treated the private key of false proof article issuer for third party's false-proof mechanism licenses to, generate security code according to first signature file and the public key information corresponding with first private key, can for: be converted into security code with first signature file and with the corresponding public key information of first private key.That is to say, the public key information of first signature file and the first private key correspondence is encoded, transform and obtain security code when first private key of authorizing with the third party.Because encrypting and obtaining first used in first signature file private key is through the mandate of third party's false-proof mechanism, therefore the security code process that obtains by such mode can embody the identity validation that third party's false-proof mechanism is treated false proof article mechanism.
Simultaneously, utilize third party's false-proof mechanism to license to treat the private key of false proof article issuer to obtain security code, can help third party's false-proof mechanism and determine the issuer that treats false proof article of the correspondence of this security code, like this, when certain article went wrong, that can determine this article correspondence treated false proof article issuer.As, when credential issuance mechanism distributed certificate indiscriminately, the security code in the certificate of utility can be determined the issuer of certificate, can avoid credential issuance mechanism to deny.
Certainly, first private key that presets also can be for treating what false proof article issuer determined voluntarily, in this case, in order to guarantee to treat the genuine and believable of false proof article issuer, promptly in order in security code, to embody the process of this arbitration, can also followingly carry out: second private key of determining unique third party's false-proof mechanism by third party's false-proof mechanism, treat false proof article issuer with first private key that presets summary info is encrypted generate first signature file after, utilize second private key of third party's false-proof mechanism that the public key information of first signature file and the first private key correspondence is encrypted and generate second signature file.Then generate the process of security code, specifically can comprise according to first signature file and the public key information corresponding with first private key:
Utilize second private key of third party's false-proof mechanism that the public key information of first signature file and the first private key correspondence is encrypted generation second signature file;
Second signature file is converted into security code.
That is to say, when first private key that presets is not during by the mandate of third party's false-proof mechanism, in order to guarantee to treat the true and reliable property of false proof article issuer, also promptly embodying the identity for the treatment of false proof article issuer by third party's false-proof mechanism confirms, then after the summary info encryption that will treat false proof article with first private key obtains first signature file, second private key that can utilize third party's false-proof mechanism is again encrypted the public key information of described first signature file and the first private key correspondence and is obtained second signature file, and second signature file is converted into security code.Like this can be when the security code of checking, have only by second PKI corresponding and could decipher second signature file with second private key of third party's false-proof mechanism, and behind deciphering second signature file, obtain the public key information of first signature file and the first private key correspondence, obtain first PKI by this public key information, and decipher first signature file, and the final summary info that obtains to treat false proof article by first PKI.Utilize second private key of third party's false-proof mechanism that first signature file is encrypted, because second private key of third party's false-proof mechanism has unicity and non-reproduction, just can guarantee to have only through just utilizing the security code that obtains of this method by passing through the false proof article issuer that treats that third party's false-proof mechanism carries out qualification testing.
Certainly, when first private key that presets is treated the private key of false proof article issuer for third party's false-proof mechanism licenses to, first private key that utilization is preset is encrypted generation first signature file to summary info after, at second private key that utilizes third party's false-proof mechanism the public key information of first signature file and the first private key correspondence is encrypted generation second signature file, and second signature file is converted into security code.Can further guarantee to treat the true and reliable property of false proof article publisher like this.
As seen through the above description of the embodiments, those skilled in the art's article anti-counterfeit method that can be well understood to the embodiment of the invention can realize by the mode that software adds essential general hardware platform.
In addition, need to prove that first private key can be arranged in the software of the article anti-counterfeit method of moving the embodiment of the invention in the embodiment of the invention, as move the computer-internal of this software.In order to guarantee that the talent that this computing machine of security can only be had a special authority can move.Certainly, first private key sets in advance and is kept at independently in the hardware, when needs utilize the method for the embodiment of the invention to generate security code, with this hardware and the operation embodiment of the invention article anti-counterfeit the related software system (as, computing machine) connects, just can pass through this software, and utilize first private key to generate the first signature file file, and finally obtain security code.The article anti-counterfeit method corresponding software of the operation embodiment of the invention can be to treat false proof article issuer, by treating that first private key that false proof article issuer utilizes the third party to authorize encrypts the article summary info, and generate security code according to the method for the embodiment of the invention.
Perhaps, also can be by the software of third party's false-proof mechanism operation embodiment of the invention article anti-counterfeit method, third party's false-proof mechanism can be by communicating with treating false proof article issuer, obtain the identity information for the treatment of false proof article issuer and the summary info for the treatment of false proof article, after treating the identity of false proof article issuer by third party's false-proof mechanism checking then, utilize first private key to encrypt the summary info for the treatment of false proof article for the treatment of false proof article issuer, obtain first signature file, again the public key information of first signature file and the first private key correspondence is passed to and treated false proof article issuer, so that treat false proof article issuer the public key information of first signature file and the first private key correspondence is generated security code, certainly, third party's false-proof mechanism also can utilize second PKI that the public key information of first signature file and the first private key correspondence is encrypted again, obtain second signature file, second signature file is passed to article issuer, so that article issuer generates security code with second signature file.
Referring to Fig. 2, the flow chart of steps for the method for a kind of article genuine-fake checking of the embodiment of the invention shows the security code that generates in the article anti-counterfeit method in the embodiment of the invention on the article of the true and false to be verified, and this method comprises:
Step S201: the image information of obtaining security code on the article by image capture apparatus;
Show the security code that generates in the embodiment of the invention article anti-counterfeit method on the article of verifying in the method for the item authentication true and false in the embodiment of the invention.
The figure that comprises image or Word message that security code is made up of strip or certain specific geometric figure, as, two-dimensional bar code/two-dimension code (2-dimensional bar code) is that the figure of the different colours block combination that (on the two-dimensional directional) distributes on the plane according to certain rules with certain specific geometric figure comes the record data symbolic information.At first need get access to by image capture apparatus the image information of article anti-counterfeit sign indicating number, so that according to the image information of security code, Item Information is finally obtained in operation such as decode to security code.
The article genuine-fake verification method of the embodiment of the invention can be realized by the mode that software adds essential general hardware platform equally, as, the software of realizing the article genuine-fake verification method of the embodiment of the invention can be installed in and be equipped with in the camera mobile phone, absorb the image information of security code by the camera of mobile phone, so that realize gathering in this method the effect of the image information of security code, and then carry out respective handling according to the image information of security code.Certainly the corresponding software of the embodiment of the invention also can be installed in other equipment with Flame Image Process capture functions, as the computing machine of band camera etc.
Step S202: according to the image information of described security code, obtain described first signature file and with the corresponding public key information of described first private key;
Owing to include the public key information of first signature file and the first private key correspondence in the security code that the embodiment of the invention obtains, after getting access to the image information of security code, image information according to security code, decode accordingly or necessary decryption processing, can get access to first signature file that comprises the article summary info and with the article anti-counterfeit method in the corresponding public key information of first private key.
Corresponding with the article anti-counterfeit method of the embodiment of the invention, when first PKI according to first signature and the first private key correspondence generates security code, according to the image information of security code, the public key information of the first private key correspondence that gets access to can be the parameter information of first PKI of the first private key correspondence; When the parameter information according to first signature and first PKI of the first private key correspondence generated security code, then according to the image information of security code, the public key information of the first private key correspondence that gets access to was: first PKI of the first private key correspondence.
Step S203: described first signature file is decrypted according to described public key information;
When the public key information of the first private key correspondence is first PKI of the first private key correspondence, the process that first signature file is decrypted according to public key information, can for: utilize first PKI that first signature file is decrypted.
When the public key information of the first private key correspondence was the generation parameter of first PKI of the first private key correspondence,, be specifically as follows the process that first signature file is decrypted according to public key information: the generation parameter information according to described first PKI generated first PKI; Utilize described first PKI that first signature file is decrypted.That is, in security code, only comprise the generation parameter information of first PKI, at first need to utilize these to generate parameter, transform and necessary computation process obtains first PKI, and then utilize first PKI that obtains to decipher first signature file.
First signature file is to utilize first private key will treat that the summary info encryption of false proof article obtains, and therefore, utilizes first PKI corresponding with first private key to be decrypted described first signature file, thereby obtains the summary info of article.And when first signature file be not when obtaining by first encrypted private key, just can not decipher the article relevant information after first signature file obtains deciphering, so these article just may be the forgery article.
