Method for tracing anti-fake markings for agricultural product

Abstract

The invention belongs to the technical field of a tracing system of agricultural products and discloses a method for tracing anti-fake markings for agricultural products. The agricultural products are coded based on a supervision model to form agricultural product tracing supervision codes; then the agricultural product tracing supervision codes are compressed and encrypted to generate a one-dimensional tracing code, the result obtained through an encryption algorithm is unique, the fact that one product with one code is achieved, individual marking and tracing can be achieved, and the anti-fake function is high. The one-dimensional tracing code and an encryption initial key of the one-dimensional tracing code are stored in a two-dimensional bar code, because the two-dimensional bar code is provided with good error correcting capacity, when the one-dimensional tracing code is damaged and cannot be recognized, the one-dimensional tracing code can be obtained from the two-dimensional bar code for the tracing, and when a network is unavailable, off-line tracing of basic information can be performed directly through the two-dimensional bar code. Simultaneously, flexible tracing for individuals and batches can be achieved through associating the one-dimensional code with the two-dimensional bar code.

Description

technical field [0001] The invention relates to the technical field of agricultural product traceability systems, in particular to an agricultural product traceability anti-counterfeiting marking method. Background technique [0002] In recent years, the quality and safety of agricultural products have become increasingly prominent, and domestic agricultural product safety and quality problems have occurred from time to time. The quality and safety of agricultural products is a worldwide hot issue. Incidents such as "leptin", "poisonous bean sprouts", "dyed steamed buns" and "hormone cucumbers" have occurred continuously in my country in recent years, which fully demonstrates that the current safety of agricultural products is not optimistic. It has caused great harm to people's health and the export of agricultural products. On the one hand, consumers hope that government functional departments will strengthen the quality supervision of agricultural products and ensure the ...

Problems solved by technology

[0007] 3. Small amount of information

[0008] 4. Weak security

[0009] 5. Slightly damaged, unrecognizable

[0010] 6. It is impossible to realize the associated traceability of individuals and batches

The current one-dimensional barcode is mainly traced by batch, and it is impossible to carry out the associated traceability of individuals and batches at the same time
