I'm looking for a solution to the problem of employee theft of intellectual property. Specifically, How can I prevent my own employees from sharing my company's CAD files with my competition? I've seen in other industries the practice of creating an "OEM" version of the application that will save only a unique format of the files created thereby requiring anyone opening the file to own a license to that OEM-version of the software. Further, use of the software license is then controlled through use of a hardware key. Has anyone successfully solved this problem with AutoCAD?
