Method for generating color garbage classification two-dimensional code

Abstract

The invention discloses a method for generating a color garbage classification two-dimensional code. The method comprises the steps of coding the garbage bag identity information to generate a uniquegarbage bag identity code; extracting an identity display code and an identity hiding code, and respectively converting the identity display code and the identity hiding code into the numerical data;respectively calculating to obtain an initial value, parameters, an initial iteration step number and an extraction interval of the chaotic system, and performing iteration on the Logistic chaotic mapping to generate a chaotic sequence; respectively scrambling the ciphertext numerical values in the three custom numerical value type data and ciphertext numerical value corresponding relation tables;and meanwhile, carrying out the corresponding forward diffusion encryption and reverse diffusion encryption on different numerical values of the identity hidden code conversion data, generating an identity hidden encryption code according to the scrambled corresponding relation table, and then generating a garbage classification code through combination, so that the color garbage classification two-dimensional code is obtained. The method for generating the color garbage classification two-dimensional code provided by the invention is simple and feasible, has very strong safety and is not easy to crack, and the generated color garbage classification two-dimensional code is convenient for guiding garbage classification, can effectively protect the privacy of the user in garbage bag identity hidden information, and has the uniqueness and safety.

Description

technical field [0001] The invention relates to the field of garbage classification, in particular to a method for generating a two-dimensional code for garbage classification. Background technique [0002] In recent years, with the rapid development of the global economy and the rapid increase in population, the scale of cities has continued to expand, resulting in a sharp increase in the amount of municipal solid waste, and the problem of municipal solid waste is deteriorating into a global crisis. The land erosion and environmental pollution caused by the "garbage siege" not only seriously threaten the public's health, but also become one of the factors that affect and restrict the sustainable development of cities in my country and even in the world. To solve the dilemma of "garbage siege", the most important thing is to realize the reduction of urban domestic waste from the source, and complete the recycling and harmless treatment of waste. Therefore, promoting the clas...

Problems solved by technology

[0003] The implementation of urban garbage classification in my country is relatively slow. The main reason is that the garbage classification codes on garbage bags either lack confidentiality or are difficult to understand the classification. For citizens who lack garbage classification knowledge, it is not clear which category a lot of garbage should belong to. If you don’t know, this will lead to conscious and unconscious littering, making the classification useless; at the same time, you still have doubts about whether the identity information of the garbage bag will leak the user’s privacy, and the worry that personal information will be exposed has also hit people to a certain extent.
