Embodiment Construction

[0037] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, in the embodiment of the method and device for increasing the security of the two-dimensional code in use of the present invention, the method includes the following steps:

[0039] Step S11 identifies and corrects the two-dimensional code to obtain decoded data: In this embodiment, the steps of obtaining the two-dimensional code and decoding the image of the two-dimensional code to obtain the data therein are actually the same as those in the prior art The relevant steps in are roughly the same. For this step, firstly, the device obtains the QR code pattern by scanning or taking pictures, then reads the information from the picture, identifies black and white blocks and correspondingly becomes "1" and "0"; decodes the format information, including correction Error levels, mask graphics, etc.; determine the version inf...

Abstract

The invention relates to a method for improving the application safety of a two-dimension code, and the method comprises the following steps: carrying out the recognition and error correction of a two-dimension code figure, and obtaining decoded data; carrying out the safety verification of obtained two-dimension code decoding data on equipment obtaining the two-dimension code; employing the obtained two-dimension code decoding data if the verification is passed, and executing a specific operation which comprises: connecting a specific linkage address or downloading a specific executable file; or quitting the application of the two-dimension code if the verification is not passed. The invention also relates to a device achieving the above method. The invention has the following effects that the requirements for an application environment are low, the cost is lower, and the consumed time is less.

Description

technical field [0001] The present invention relates to the field of data processing, and more specifically, to a method and device for increasing the security of using two-dimensional codes. Background technique [0002] Two-dimensional code technology is a technology that can replace barcodes. Because its encoding method is two-dimensional, it can carry richer information than one-dimensional barcodes. There are currently international standards for QR code technology that define the process of encoding and decoding. In the encoding process, different grouping methods are used for different data types, and after adding error correction codes, they are encoded into small black and white squares, and after mask processing (making the distribution of black and white blocks more uniform), a two-dimensional code is generated. The decoding process of the two-dimensional code is to identify 1 and 0 according to the black and white blocks, and then determine the encoding method a...
