Abstract :
With the rapid development and continuous application of network and CAD technology, data safety of product has become an outstanding problem day by day. At present, the protection technology of CAD model mainly includes information hiding, digital watermark and control technology of user role and access permission. Based on previous study conclusion, a new encrypt CAD model has been developed, so this text gives a general introduction of whole system model; gives the gross figure, module definition and some internal relations; put forward theory difficulties of model and quasi solutions.
