Intelligent numerical control machine tool code data security storage method

The invention relates to the technical field of data protection, in particular to an intelligent numerical control machine tool code data security storage method, which comprises the following steps: acquiring a plurality of code data segments of a to-be-compressed code data sequence, and according to the distribution condition of parameter codes in code data of each model code in each code data segment and the code data distribution condition, determining the code data of each model code in each code data segment; determining the parameter code similarity of each type of code in each code data segment, and determining the segment code similarity of each code data segment according to the proportion difference of code data corresponding to the same type of code in every two adjacent code data segments; and in combination with the parameter code similarity and the segment code similarity, determining a disorder parameter of each code data segment, further determining a transformation sequence corresponding to
