and acquiring the total number of bytes of the quality safety data, and obtaining a traceability value through the product of the ratio of the total number of bytes of the quality safety data to the total number of available bytes and the storage regulation coefficient.
8. The fresh product quality safety tracing intelligent management system of claim 7, wherein the storage data obfuscation module for obfuscating in performing quality safety data storage comprises:
obtaining a source tracing block for generating a second sending node and a second receiving node, and marking the source tracing block as a confusion source tracing block, wherein the confusion source tracing block stores the second sending node and the second receiving node at the same time;
acquiring quality safety data, and selecting an injection characteristic character at any byte section, wherein the quality safety data injected with the characteristic character is marked as obfuscation data;
and storing the obfuscation data in the obfuscation source block to complete the obfuscation processing.
9. The fresh product quality safety tracing intelligent management system as claimed in claim 8, wherein the obfuscating data of the obfuscating data and the quality safety data is associated with the quality safety data, and when the quality safety data is deleted, the obfuscating data is also deleted;
the total number of bytes of the obfuscation data and the quality safety data is the same, and the signatures and the attributes of the obfuscation data and the quality safety data are the same.
10. The intelligent fresh product quality safety traceability management system of claim 9, wherein the traceability module is configured to extract quality safety data in a traceability block, and comprises:
sending the attribute codes of the tracing blocks, the second receiving node and the tracing values of the storage tracing blocks to the extraction terminal;
and when the attribute codes, the second receiving nodes and the traceability values are input by the extraction terminal, matching the corresponding traceability blocks and extracting quality safety data corresponding to the second receiving nodes.
