Detailed Description

in order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following describes in detail a specific implementation of the two-dimensional code display method and apparatus based on mobile payment device according to the present invention by using an embodiment and with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 is a schematic flow chart of a two-dimensional code display method based on a mobile payment device in an embodiment. The method specifically comprises the following steps:

step 101, receiving two-dimensional code generation request information and a two-dimensional code generation request instruction.

And 102, dividing the two-dimension code generation request information into public information and private information according to privacy grades. It is understood that the privacy information indicator is a read continuation indicator, defined as a "READCONNECTION" string.

And 103, carrying out encryption algorithm encryption operation on the private information, and carrying out digital signature operation on the private information based on the encrypted private information.

Specifically, the encryption operation of the encryption algorithm on the private information includes: encrypting the private information by adopting an encryption algorithm, and carrying out bit stream transformation on the encrypted private information and the encrypted public information; acquiring a bit stream string of private information and a bit stream string of public information; and sequentially connecting the bit stream string of the public information, the terminator, the privacy information indicator, the bit stream string of the privacy information and the terminator according to the sequence to generate a final bit stream string. Therefore, the safety of the two-dimensional code is improved. The terminator is defined according to QR code standard, wherein the QR code standard is ISO/IEC18004 standard.

It is understood that the public information is subjected to bit stream conversion to obtain a bit stream string of the public information, and a terminator is added after the bit stream string of the public information; judging whether the information to be coded carries privacy information or not, if so, adding an information mode judgment type privacy information indicator after a terminator of a bit stream string of the public information; otherwise, the execution operation is ended, and the bit stream string with the public information of the terminator is taken as the final bit stream string. Further, the QR two-dimensional code generating equipment encrypts the private information by adopting an encryption algorithm; carrying out bit stream conversion on the encrypted private information to obtain a bit stream string of the private information, and adding a terminator behind the bit stream string of the private information; and adding the bit stream string of the privacy information with the terminator into a privacy information indicator READCONTIONUE to obtain a final bit stream string.

In addition, when the public information does not exist, the bit stream string of the public information is an empty string, and a terminator is added after the empty string; when the code is scanned and the information is read, correspondingly, the public information part is a null character string; when the privacy information does not exist, the privacy indicator is not added, and when the code is scanned and the information is read, correspondingly, after the terminator is read, if the privacy indicator does not exist at the back, the continuous reading is stopped; or when the private information does not exist, adding a private indicator, wherein the bit stream string of the encrypted private information is null, adding a terminator after the bit stream string of the encrypted private information, scanning the code to read the information, correspondingly reading the bit stream string of the encrypted private information after the private indicator until the terminator is read, decrypting the bit stream string of the encrypted private information, and finally recording the private information part as a null character string if the decryption result is null string or messy code.

Further, performing a digital signature operation based on the encrypted private information includes: and loading the digital signature information and generating an image gray scale value of the digital signature information. Therefore, the safety of the two-dimensional code is improved. It will be appreciated that the image gray scale value of the digital signature information may be superimposed on the image gray scale value of the original data. The specific method comprises the following steps: superposing the image gray value of the original information and the image gray value of the digital signature information in a center alignment mode; superposing the image gray value of the original information and the image gray value of the digital signature information by a specified pattern; and superposing the image gray value of the original information and the image gray value of the digital signature information by a specified gray value. It should be noted that the overlapping positions of the image grayscale value of the original information and the image grayscale value of the digital signature information may be in a dispersed form. In addition, the overlapping position of the image gray scale value of the original information and the image gray scale value of the digital signature information is set in a manner that both parties know, agree with or negotiate, and is not disclosed to the outside.

It should be noted that the two-dimensional code display method based on the mobile payment device further includes: judging whether a registration request of the mobile payment device is received; if a registration request is received, carrying out digital signature information loading operation on two-dimensional code generation request information according to a received two-dimensional code generation request instruction; and if the registration request is not received, the loading operation of the digital signature information of the two-dimensional code generation request information is not executed, and the registration invitation information is pushed to the mobile payment equipment.

In addition, if a registration request is received, the performing, according to the received two-dimensional code generation request instruction, a digital signature information loading operation on the two-dimensional code generation request information includes: and after receiving the two-dimension code generation request finger, carrying out digital signature information loading operation on the two-dimension code generation request information by using a private key based on an asymmetric encryption algorithm.

it can be understood that, according to the difference of the two-dimensional code generation request information, the private key used in the digital signature information loading of the two-dimensional code generation request information is different.

And 104, extracting the coded data in the privacy information after the encryption and digital signature operations are finished, and coding the coded data according to a two-dimensional code generation algorithm.

And 105, pushing the coded two-dimensional code image to mobile payment equipment for dynamic display.

In one embodiment, pushing the encoded two-dimensional code image to a mobile payment device for dynamic display comprises: and mixing channel noise into the coded two-dimensional code image in the pushing process.

The invention provides a two-dimensional code display method based on mobile payment equipment, which comprises the steps of receiving two-dimensional code generation request information and a two-dimensional code generation request instruction; dividing two-dimensional code generation request information into public information and private information according to privacy grades; carrying out encryption algorithm encryption operation on the private information, and carrying out digital signature operation on the basis of the encrypted private information; extracting coded data in the privacy information after the encryption and digital signature operations are completed, and coding the coded data according to a two-dimensional code generation algorithm; and pushing the two-dimensional code image subjected to coding to mobile payment equipment for dynamic display. According to the method, the two-dimension code is dynamically replaced on the mobile payment equipment, so that the flexibility and the usability of the merchant for replacing the two-dimension code are realized.
