Embodiment Construction

[0036] see figure 1 , the encryption method of QR code includes:

[0037] Step S101, the computer obtains the original graphic of the two-dimensional code, and obtains the original data information of the two-dimensional code after decoding;

[0038] Step S102, the computer uses the encryption software to perform the ECC encryption operation on the original information of the two-dimensional code and the real-time clock information generated by the clock module with the EK encryption key to obtain an encrypted data that changes with time;

[0039] Step S103, the computer encodes the encrypted data through encoding software to generate a new two-dimensional code graphic and display it on the display screen;

[0040] Step S104, after 30 seconds, repeat steps S102 to S103.

[0041] see figure 2 , figure 1 The decryption method corresponding to the two-dimensional code encryption method in Chinese, including:

[0042] Step S201, the mobile phone obtains the QR code graphics ...

Abstract

The invention discloses a two-dimensional code encryption / decryption method. The method comprises the following steps that: two-dimensional code original information is obtained; an EK (electronic key) encryption key is used to perform ECC (Error Correction Code) encryption operation on the two-dimensional code original information and real-time clock information to obtain encrypted data jumped as time goes; the encrypted data is encoded to generate a new two-dimensional code figure; the two-dimensional code figure jumped as time goes is obtained; the two-dimensional code figure is decoded to obtain encrypted data jumped as time goes; and DK decryption key is used to perform ECC decryption operation on the encrypted data to obtain decryption information. The two-dimensional code encryption / decryption method performs algorithm encryption according to two-dimensional code original data, generates the two-dimensional code jumped as time goes, and ensures that the two-dimensional inquiry codes obtained by terminal users are different for each time, verification steps are decreased, and the security and the non-repeatability of the two-dimensional code are guaranteed.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a jumping two-dimensional code encryption / decryption anti-counterfeiting technology. Background technique [0002] At present, the two-dimensional code anti-counterfeiting technology is more and more widely used in all walks of life, and the information hidden in the two-dimensional code is the core of the technology. [0003] Two-Dimensional bar code (2-Dimensional bar code) is a black and white graphic that uses a specific geometric figure distributed on a plane (that is, in a two-dimensional direction) according to certain rules to record data symbol information. In the coding, the concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer are skillfully used, and several geometric shapes corresponding to binary are used to represent the text and numerical information, which are automatically input through image input devices or p...
