Abstract
The invention relates to an object identity certification method based on a short-distance wireless communication function of a short-distance communication terminal; and by adopting the method, the communication of a non-contact intelligent card and an RFID (radio frequency identification) is realized, the bottleneck that the recognition function of the original electronic tag is unavailable is broken through, and meanwhile, the object identity is difficult to forge and attack by the certification at a server-side by using a public secret key system and a public communication network in terms of technique principle. After the electrical verification is successful, the description for an object and the characteristic information described by characters or images are returned from the server-side, so that a user can compare the object with the actual object. The verification result can be used as commodity data to be stored for market analysis.
Description
Technical field
The present invention relates to the digital verification that adopts the cryptography theory that article are carried out, particularly a kind of item authentication method based near field communication (NFC) terminal.
Background technology
The checking of commodity and false proof aspect; Adopt the cryptography principle to carry out online digital verification; Utilize the result of calculation of cloud computing server end to confirm article identity, can obtain antifalse effect preferably, improve attack and counterfeiter's cost greatly with the cost of lower manufacturing side.Technological first ratio with various physics are made repeatedly has advantage.Aspect the product of low side, the method that has had numerous stationary digital codings of setting in advance with businessman to cover printing ink is carried out the checking of product, obtains certain effect.
The code of printing is a stationary digital, though with low cost, there are many drawbacks.Compare with the fixed code of printing; The data of radio frequency sign and contact type intelligent card are to encrypt or dynamically produce, are difficult to copy and clone, and can be multiplexing; This has just greatly improved the threshold that is replicated and attacks, and can more effectively protect the interests of production production firm.
But the present radio frequency sign and the terminal of non intelligent card belong to special-purpose terminal more, and this has just caused fake certification can't popularize with general, only is used in certain scope.Simultaneously, mostly in the data reading terminals, exist this leak that to be attacked to the particularly cryptographic checking flow process of the process of reading of target data.
Near-field communication is claimed in the low coverage communication again; English is Near Field Communicaiton, and abbreviation NFC is a kind of mechanics of communication of being participated in and being developed by numerous international bodies and company; Make short-range wireless telecommunications of term and exchanges data, and compatible mutually with several kinds of RFID commonly used.Such as being operated in the contact type intelligent card that 13.46 megahertzes meet standards such as ISO 14443A and 14443B.Because the advantage of NFC in information exchange, this technology is adopted at mobile communication terminals such as mobile phone and panel computers rapidly.
Summary of the invention
The objective of the invention is to provides a kind of item authentication method based near field communication (NFC) terminal, to overcome the incomplete problem that exists in the item authentication under the prior art to the existing defective of item authentication.
To achieve these goals, the present invention provides a kind of item authentication method based near field communication (NFC) terminal, and its characteristic may further comprise the steps:
Step a: article have the Near Field Communication sign of coding in advance;
Step b: near field communication (NFC) terminal obtains the mark number of article;
Step c: the identification number that will obtain article is sent to background server through network, carries out cryptography arithmetic, obtains verification msg and intrinsic data;
Steps d: the authenticity that verification msg and intrinsic data is turned back to the near field communication (NFC) terminal checking article.
The mark number of the said article of item authentication method in step b based near field communication (NFC) terminal comprises the trade name of article model, article, the trade mark of article, the bar code of article, the sequence number of article, unique sequence number UID of Near Field Communication sign etc.; The obtaining means of the mark number of article can also be used the method input terminal of optical scanner and artificial input except employing Near Field Communication terminal obtains automatically.
Said item authentication method based near field communication (NFC) terminal is in the data of verification msg for producing and obtain according to the cryptography principle described in the step c, is used for and undertaken alternately by the mark number on the authenticating items, to accomplish proof procedure; Said intrinsic data are by the correct result of authenticating items, and determine whether near field communication (NFC) terminal, to show according to the result of checking.
Said item authentication method based near field communication (NFC) terminal in verification msg described in the step c only from background server; Near field communication (NFC) terminal does not carry any function that can individual authentication article authenticity, can only accomplish verification operation through the verification msg that background server returns.
Said intrinsic data can provide by the certified products visual information such as the feature descriptions such as literal, picture of checking article, as supplementary and the manual identification information beyond the checking result.
Adopt logic encryption card like the Near Field Communication sign; Then the verification method of steps d is: verification msg is pairing password and the Card Reader correct result expected; Item Mark is deciphered the information of reading with the password that the employing of low coverage communicating terminal obtains from background server and correct result is compared.
Adopt the CPU contactless smart card like the Near Field Communication sign, then a kind of verification method of steps d is: verification msg comprises the required parameter of password reconciliation signature of encrypted tunnel; Confirmation method is: set up encrypted tunnel with password, read the data of smart card, then data are separated the operation acknowledgement result of signature.
Adopt the CPU contactless smart card like the Near Field Communication sign; Then the another kind of verification method of steps d is: when the Near Field Communication terminal when Near Field Communication sign is set up data and is connected; The Near Field Communication sign is except providing sequence number; Also initiatively send the random challenge data, after these data are read at the Near Field Communication terminal, deliver to the background server end the challenge signature; Send challenge data, expected data and intrinsic data behind the signature back to the Near Field Communication terminal then, do by the CPU in the Near Field Communication sign and separate signature; If signature passes through, the Near Field Communication sign can discharge needed verification msg and give the Near Field Communication terminal; The data that the Near Field Communication sign discharges can directly be compared with the expected data that background server is come, and also can do affirmation with the way of signature verification.
Must store the background server pairing PKI digital certificate of signing in the said CPU contactless smart card, Digital Signature Algorithm can adopt DSA, RSA, the public key algorithm that ECDSA etc. are general.
After said item authentication method based near field communication (NFC) terminal is verified in steps d and finished, near field communication (NFC) terminal will verify that the result is delivered to background server, as the data source of obtaining statistical information.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
