Hello!
In Excel I have developed a front end data browser that gives access to a whole raft of survey data stored in the same file. This browser, and the data involved, has value that we sell on to interested clients for a license fee.
My concern is that it is relatively easy for one person with a license to forward the file onto someone else who does not, thereby doing us out of potential revenue!
I am interested if anyone can suggest any ideas to help manage this. For instance, we have implemented a time stamp in the code that will shut down / delete / stop the files functioning unless a renewed license is available.
Can anyone suggest a method, perhaps in VBA code, to create an invisible stamp on the file that is unique to each license, in order that we can track the source of any illegally copied files?
