Embodiment Construction

[0029] The invention provides a code map with a time-limiting function, in which code information with usage time-limiting instructions is added, and the code information records the effective time use interval value of the code map. Wherein, the effective time use interval value is the time when the code map can be effectively used, and the time use range is several minutes or several minutes, several hours or tens of hours.

[0030] If the valid time period of the code map recorded in the code information is two hours, therefore, the valid use time period of the code map is only two hours, once it exceeds two hours, it is determined that the code map and the code map are implanted The item in the picture is invalid.

[0031] Use the code image reading device to read the code image implanted on the surface of the article for the first time, and the start time point of successful reading is the valid time interval represented by the code information of the use time limit instr...

Abstract

The invention provides a code image with a time limit function. The code image is provided with code information, which contains time limit instructions and records the effective use time interval value of the code image. The generating method of the code image comprises inputting the code information containing the time limit instructions into a code image generating interface; combined with a code image generating library, generating the code information into the code image with the use time limit function and uploading the code image to a cloud server. The reading method of the code image comprises reading the current code image twice to obtain the use time range information of the code image; after comparing the use time range information with the effective use time interval value information, determining whether the code image is still a valid code image during the secondary reading. The code image capable of being used within an effective time range can avoid being illegally used by counterfeiters.

Description

technical field [0001] The invention relates to an anti-counterfeiting code map, in particular to a code map with a time-limiting function, a generation method and a reading method thereof. Background technique [0002] At present, the existing code map generally does not have the function of limiting the use time, therefore, the code map is easy to be illegally used by counterfeiters. Contents of the invention [0003] Aiming at the deficiencies in the above problems, the present invention provides a code map that can only be used within the effective time range, so as to prevent the code map from being illegally used by counterfeiters. read method. [0004] In order to achieve the above object, the present invention provides a code map with a time-limiting function, in which code information with usage time-limiting instructions is added, and the code information records the effective time interval value of the code map. [0005] The above-mentioned code map with time-...
