A method for information protection in collaborative assembly design

Information security and assurance are emerging frontiers for collaborative design. The collaborative assembly design becomes one style of cooperation in both design and the outsourcing manufacture. However, during this process, some sensitive information that is secret to certain cooperators is at the risk of leakage. IA is of high need in this process. In this paper, we propose a method that provides the ability to hide the sensitive information while releasing the necessary information for the collaborative assembly design and the outsourcing manufacture. Taking the B-rep model as the original input directly, this method provides the solution of information protected model also in B-rep. Moreover, a prototype system SSDSCA carrying out this method has been implemented.
