Protecting / Securing Files from Being Copied to Another Computer
I am new to filemaker. My client asked me to build an invoicing systerm for his manufacturing company. I think I can do this, and I am also thinking about selling the "solution" (layouts, files, etc.) to others in the same manufacturing field. My one question is, how can I protect the files,folders, layouts and the rest from being copied, so that it cannot be copied from one computer to another (that have filemaker) without my permission?
I know there is no way to protect it completely, but want to have maximum protection as possible.
Thank you in advance for your help.
