Abstract
The present invention disclose a kind of safer QR codes and generated and read method, belongs to field of information encryption, primary data is analyzed, data encoding, error correction；Then code word filling is carried out, C is obtained1, confidential information is encrypted and Error Correction of Coding obtains C2, secret embedded location is generated according to key and is replaced, QR codes are exported after last arranging graphic, addition mask and version information.Invention introduces the concept of domestic consumer and advanced level user, it is possible to achieve the user of different identity or different conditions obtains different information from same Quick Response Code.Domestic consumer can use standard two-dimensional code decoding software to read public information, and advanced level user reads confidential information using key and special Quick Response Code decoding software, and the present invention can also avoid deletion to confidential information and distort.
Description
Technical field
The present invention is in belonging to field of information encryption, more particularly to a kind of QR codes generation and read method.
Background technology
Barcode technology is largely used as a kind of fast exchange means of small data quantity in recent years, one of which typical case
Representative be exactly QR codes, QR is a kind of Quick Response Code.Tourist attractions carry out sight spot explanation using QR codes, and smart phone user is by sweeping
QR codes are retouched just it is recognized that the background knowledge at many sight spots；QR codes can store web page interlinkage, just can be with by scanning QR codes
It is connected to the website all answered up；QR codes are also applied to identity discriminating and business transaction field etc..QR codes are non-with prospect
Often extensively, and in many cases QR codes carry information be not intended to disclosed in, can just be achieved the goal by way of encryption.
But the current Quick Response Code concept without rights management in itself, in theory anyone can read information.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide a kind of safer
QR codes generate read method.
To achieve the above object, the invention provides a kind of safer QR code generating methods, comprise the following steps：
Step 1: analyzing primary data；
Step 2: carrying out data encoding；
Step 3: carrying out error correction to coding；
Step 4: carrying out code word filling, C is obtained1；
Step 5: exporting QR codes after arranging graphic, addition mask and version information；
Following steps are also performed between step 4 and step 5：
Step A1, confidential information is encrypted and Error Correction of Coding obtains C2, the C2There is n bit, n is positive integer；
Step A2, the embedded location [p according to key generation secret1,p2,…,pn]；
Step A3, use C2I-th of bit replace C1PthiIndividual bit, 1≤i≤n.
Present invention also offers a kind of safer QR code read methods, carry out according to the following steps：
Step 1. is decoded to QR codes, and identification version information, removal mask obtain C1；
Step 2. generates embedded location [p according to key1,p2,…,pn]；
Step 3. extracts C1In be located at [p1,p2,…,pn] bit C2；
Step 4. is to C2Carry out error correction decoding and decryption obtains confidential information.
The beneficial effects of the invention are as follows：Invention introduces the concept of domestic consumer and advanced level user, it is possible to achieve different
The user of identity or different conditions obtains different information from same Quick Response Code.Domestic consumer can use standard two-dimensional code
Decoding software reads public information, and advanced level user reads confidential information, the present invention using key and special Quick Response Code decoding software
The deletion to confidential information can also be avoided and distorted.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of QR codes generation of the present invention.
Fig. 2 is the schematic flow sheet that QR codes of the present invention are read.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of safer QR code generating methods, comprise the following steps：
Step 1: analyzing primary data；
Step 2: carrying out data encoding；
Step 3: carrying out error correction to coding；
Step 4: carrying out code word filling, C is obtained1；
Step 5: exporting QR codes after arranging graphic, addition mask and version information；
In the present embodiment, following steps are also performed between step 4 and step 5：
Step A1, confidential information is encrypted and Error Correction of Coding obtains C2, the C2There is n bit, n is positive integer；
Step A2, the embedded location [p according to key generation secret1,p2,…,pn]；
Step A3, use C2I-th of bit replace C1PthiIndividual bit, 1≤i≤n.
As shown in Fig. 2 a kind of safer QR code read methods, are carried out according to the following steps：
Step 1. is decoded to QR codes, and identification version information, removal mask obtain C1；
Step 2. generates embedded location [p according to key1,p2,…,pn]；
Step 3. extracts C1In be located at [p1,p2,…,pn] bit C2；
Step 4. is to C2Carry out error correction decoding and decryption obtains confidential information.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
