Step S12：The biological attribute data with the standard biological characteristic to prestore is matched, determines matchingValue.
Herein, the standard biological characteristic to prestore is referred to target data permission in acquisition image in 2 D codeValidated user biological attribute data.
Step S13：Judge whether the matching value is more than preset matching value.
The preset matching value referred in step S13 is a pre-set numerical value before image in 2 D code is decoded, and is usedIn the identity for distinguishing active user and validated user.Specifically, matching value can be a percentage, the value range of matching valueCan be 0% to 100%, preset matching value could be provided as 70%.It is assumed that the matching value that step S12 is determined is 67%, then67% is less than 70%, then it is assumed that active user is not validated user.In this case, active user is not allowed to obtain Quick Response Code figureTarget data as in can return to a prompt message to active user, prompt active user can not be to the Quick Response Code figureAs being decoded.
Step S14：If the matching value is more than preset matching value, to the target data subregion of the image in 2 D code intoRow decoding, obtains target data.
Target data refers mainly to, and user wishes the part critical data transmitted by image in 2 D code.Specifically,To after target data, the target data is returned into the active user.
As it can be seen that the coding/decoding method embodiment of image in 2 D code provided by the present invention, before being decoded to target data, meetingFirst obtain the biological attribute data in image in 2 D code, then to biological attribute data and the standard biological characteristic that prestores intoRow matching, determines matching value, then judges whether matching value is more than preset matching value, is only more than preset matching value in matching valueUnder conditions of, it just will continue to be decoded the target data in image in 2 D code, so that image in 2 D code has guarantorClose property effectively reduces the security risk of image in 2 D code.
The decoding apparatus embodiment of image in 2 D code provided by the invention is introduced below, Quick Response Code described belowThe decoding apparatus of image can correspond reference with the coding/decoding method of above-described image in 2 D code.
