Method for preventing leakage of model data in equipment management platform

The invention discloses a method for preventing leakage of model data in an equipment management platform. The method comprises the following steps of (1) providing a model processing part; (2) engraving a model; (3) encrypting the model data through a secret key, and storing the encrypted model data into a model server; (4) making a terminal computer request the model data; (5) judging whether the terminal computer is an authentication terminal or not; (6) if a judgment result of the step (5) is yes, continuing to judge whether an authentication process is carried out or not; (7) if the judgment result of the step (6) is yes, reading into a memory of the terminal computer, decrypting and presenting; (8) after use, when the terminal computer saves the model data of the memory into a terminal storage device, encrypting the model data again; and (9) closing a client and a browser, and deleting the data. According to the method, the encrypted model data can only be opened in the computerterminal and the program
