Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Existing planar bar code technology substantially belongs to wildcard type, i.e., all users belong to same level of confidentiality, it can be seen that same
Data information, needing by information carry out level of confidentiality differentiation scene in, the practicability is poor for existing planar bar code technology, be based on this,
A kind of two-dimensional code generation method provided in an embodiment of the present invention, apparatus and system, the technology can be applied to supermarket, market and its
He needs to carry out information in the scene of level of confidentiality differentiation.
For convenient for understanding the present embodiment, first to a kind of two-dimensional code generation method disclosed in the embodiment of the present invention
It describes in detail.
A kind of flow chart of two-dimensional code generation method shown in Figure 1, the specific steps of this method, comprising:
Step S102 obtains be-encrypted data.
Above-mentioned be-encrypted data is usually the information data in the scene for need to carry out information data level of confidentiality differentiation, the letter
Breath data can be divided into different classified datas according to the difference of level of confidentiality, and therefore, the user for possessing different security level is available
The data that can be obtained in oneself permission.
Step S104 carries out level of confidentiality division to be-encrypted data, obtains multiple levels of confidentiality according to preset level of confidentiality division rule
Data.
Above-mentioned preset level of confidentiality division rule, which can be, carries out level of confidentiality division, example for be-encrypted data according to user type
Such as, it is difference in the merchandise news that supermarket, customer and Supermarket management person wish to, therefore, merchandise news can be divided into two
A classified data, a classified data include price, the place of production and the date of manufacture etc. that customer wishes to, another classified data
The inventory of the commodity wished to including Supermarket management person and sales situation etc..
Multiple classified datas are passed through corresponding public key respectively and encrypted by step S106, obtain it is corresponding it is multiple plus
Data after close.
The band encryption data of acquisition is subjected to graded encryption, wherein each classified data is added using different public keys
It is close, for example, being respectively Low Security Level data and High Security Level data there are two classified data, Low Security Level data are carried out using public key 1
Encryption, obtains encrypted data 1；Highly dense data are encrypted using public key 2, obtain encrypted data 2, wherein encryption
RSA Algorithm can be used in algorithm.
Above-mentioned RSA Algorithm can be described as asymmetric algorithm for encryption technology, which (is equivalent to using public-key cryptography
Above-mentioned public key), and decruption key is maintained secrecy using private key, the encryption-decryption algorithm of RSA Algorithm be it is disclosed, i.e., added by public key
Close content can with and can only be decrypted by private key, and by the content of private key encryption can with and can only be carried out by public key
Decryption, that is to say, that this pair of of public key, the private key of RSA Algorithm may serve to encrypt and decrypt, and the content of side encryption
Can by and can only be decrypted by other side.
Step S108 generates the corresponding two dimensional code of multiple encrypted datas by preset two dimensional code generating algorithm.

Encryption, obtains two-dimensional code data；Numeric data code word and error correcting code word, two-dimensional code data after being corrected are carried out to two-dimensional code data；
Internal layer encryption is carried out to two-dimensional code data after correction, generates two dimensional code.
By multiple encrypted datas by two dimensional code generating algorithm, corresponding two dimensional code is generated, for example, by above-mentioned Low Security Level
Data and the corresponding encrypted data 1 of High Security Level data and encrypted data 2, obtain two dimensional code by two dimensional code generating algorithm,
It is illustrated in figure 2 the flow chart of the two-dimensional code generation method of two classified datas.
Two dimensional code user scans the two-dimensional code the above-mentioned two dimensional code that authenticating party obtains, and after scan data is put into oneself
Platform, finally by the level of confidentiality permission of oneself obtain corresponding private key from two dimensional code authenticating party, by private key to two dimensional code carry out
Data deciphering, to obtain the data that can be obtained in oneself level of confidentiality permission.
The embodiment of the invention provides a kind of two-dimensional code generation methods, first acquisition be-encrypted data；According to preset close
Grade division rule carries out level of confidentiality division to the be-encrypted data, obtains multiple classified datas；Then multiple classified datas are distinguished
It is encrypted by corresponding public key, obtains corresponding multiple encrypted datas；It is raw by preset two dimensional code generating algorithm
At the corresponding two dimensional code of multiple encrypted datas.The present invention divides level of confidentiality encryption to generate two dimensional code classified data by public key,
In the scene for needing to carry out information level of confidentiality differentiation, the practicability of two dimensional code is improved, while it is more to be conducive to two dimensional code storage
Data.

Step S304 carries out level of confidentiality division to be-encrypted data, obtains multiple levels of confidentiality according to preset level of confidentiality division rule
Data.
Step S306 obtains the corresponding public key of each classified data according to RSA Algorithm.
Above-mentioned RSA Algorithm is a kind of public key encryption algorithm, and it is true which is based on a foolproof number theory: by two
It is very easy that Big prime is multiplied, but wants extremely difficult to its product progress factorization.Therefore product can be disclosed to work
For encryption key, i.e. public key, and two Big primes are combined into private key；Public key can be issued for anyone use, and private key is then
Oneself is all, is used for decryption.
Using RSA Algorithm, determines the corresponding public key of each classified data, encrypted with the data to each level of confidentiality.
Step S308 encrypts each classified data according to corresponding public key, to obtain multiple encrypted datas.
Each classified data corresponds to different public keys, and each classified data is directed to its corresponding public key and is added
It is close, obtain the corresponding encrypted data of all classified datas.
Step S310 carries out outer layer encryption to multiple encrypted datas, obtains two-dimensional code data.
Step S312 carries out numeric data code word and error correcting code word, two-dimensional code data after being corrected to two-dimensional code data.
Step S314 carries out internal layer encryption to two-dimensional code data after correction, generates two dimensional code.
It is illustrated in figure 4 the schematic diagram of two dimensional code generation, first by text (being equivalent to above-mentioned encrypted data) or figure
Piece carries out outer layer encryption, obtains two-dimensional code data, and two-dimensional code data is then carried out numeric data code word, is equivalent to two-dimensional code data
It is encoded, then error correction (being equivalent to error correcting code word) is carried out to the data after coding, the two-dimensional code data after being corrected；Then
Internal layer encryption is carried out to the two-dimensional code data after correction, ultimately produces two dimensional code.The two dimensional code mass two-dimensional bar code (PDF417
Code) and matrix two-dimensional code (QR).
The present embodiment is by distinguishing encryption to two-dimensional code data, to achieve the effect that divide level of confidentiality；Meanwhile from data
Encryption direction improves existing planar bar code technology, although the data of existing two dimensional code storage are few, by changing for algorithm
Into the data of two dimensional code storage from now on have the growth of the order of magnitude, and therefore, the encryption of two-dimensional code data is just particularly important.
