Ji development.In order to better adapt to the fast development of economic society, preferably solve enterprises and institutions' Information Communication safety,
Reliability and trackability, improve safety and the standardization of information management further, simultaneously as most enterprise is at its commodity
During circulation, need to review commodity with false proof.Country and enterprise will spend substantial amounts of manpower and financial resources every year
Crack down on counterfeit goods for false proof.But, be limited by anti-counterfeiting technology, false proof mode single, ordinary consumer lacks the factor such as false proof instrument,
Antifalse effect is undesirable.And the appearance of QR Quick Response Code compensate for this shortcoming just, it has multiple anti-fake characteristic, therefore has
Extremely strong security and antiforge purpose performance.
A kind of QR false proof traceability system of code encryption method based on RSA Algorithm uses RSA Algorithm encryption QR code technology to producing
Product identify, and by Quick Response Code printing or labeling on product is packed, user only need to be carried out by the Quick Response Code cell phone software specified
Solve code check, i.e. can verify that authenticity of products, it is thus achieved that detailed information.Quick Response Code can store abundant product information, by encryption
Being difficult to be replicated and usurp, product information is issued from official of enterprise, and inquiry channel is regular, professional, it is achieved that Anti-counterfeiting of Product
High efficiency.
Greatly developing of technology of Internet of things, to the false proof tracing management of enterprise product quality, it is provided that a broader pipe
Platform.User reviews merchandise news, by two-dimension code anti-counterfeit based on Internet of Things by smart mobile phone scanning Quick Response Code identification
Application, chops the circulating pathway of fake products technically off, based on the QR Quick Response Code encryption anti-counterfeiting trace-back technique on the basis of Internet of Things, and will
Become strong " weapon " hitting counterfeit and shoddy goods, reviewing the defective product flow direction.
At present, also there is no the identification system of a kind of rsa encryption QR code with such high security, therefore, master of the present invention
For problem above, QR code identification system is proposed improvement project and recognition methods.
[summary of the invention]
The present invention is primarily directed to user to be needed the encryption of QR digital content and requires have high secrecy effect, it is proposed that
The identification system of a kind of QR code encryption method based on RSA Algorithm and recognition methods.
The identification system of a kind of QR code encryption method based on RSA Algorithm mainly includes that cleartext information encryption produces QR code figure
Picture, the collecting device of QR code image and the client deciphering of rsa encryption QR code based on android system identify three parts.Bright
The encryption part of literary composition information mainly uses and utilizes private key that cleartext information encryption is generated QR code image, the image acquisition of QR code hard
Part equipment, specifically includes the parts compositions such as pcb board, camera lens, holder and light filter, DSP (CCD uses), sensor.Image acquisition
By camera lens, projecting on sensor by the optical imagery of generation, then optical imagery is converted into the signal of telecommunication, signal of telecommunication warp again
Crossing analog digital conversion and become digital signal, digital signal is through DSP processed, then is sent in cell phone processor process,
It is ultimately converted to the image seen on mobile device display, the image collected is carried out pretreatment, utilize decipherment algorithm to obtain
Effective information in the QR image that must gather., the client deciphering identification division of rsa encryption QR code based on android system
PKI is predominantly used the information of the collection of the photographic head of smart mobile phone to be decrypted identification and is shown to user.
A kind of method utilizing RSA Algorithm encryption to produce QR code image for cleartext information, as shown in flow chart 1.
Client utilizes smart mobile phone identification rsa encryption QR code image module part based on android system: be responsible for knowledge
The QR code of not overall rsa encryption, after the photographic head i.e. QR code image capture device of smart mobile phone collects QR code image, first
Through QR code Image semantic classification, obtaining decoding information through the decoding of QR code again after pretreatment, when obtaining QR code decoding information, RSA adds
According to pre-defined rule, the identification module of close QR code then judges that this QR code is as encryption mode, if it is determined that be encryption mode, then will translate
Code information transfers to rsa encryption QR code identification module to process, and carries out overall deciphering, thus obtains cleartext information.
[advantages of the present invention and good effect]
Compared with prior art, the invention have the advantages that and good effect:
By using rsa encryption QR code technology, can meet the user's high requirement to secure content, encryption safe can
Lean on.Additionally, user is without extra hardware identification equipment, user only needs to use the intelligence being provided with dedicated scan client
Mobile phone, scanning rsa encryption QR code image can intelligent recognition coding information.Realize low cost, it is not necessary to buy specialized hardware scanning
Equipment.
