can anyone help me how to encrypt/protect a ttf/otf font file so that it could not be copied or used. Actually I am Arabic/Urdu font developer, I had developed many fonts, now I want to sale my fonts, but I need a protection that my font will run only on that system, which is allowed by me. I want to apply protection to avoid piracy of my fonts.
How it could be done?
Some font foundries are using a technique. they encrypt font file, you can not access its OT tables, you will be able to see fonts glyphs only. But the allow use of their font through their plugin which allows to run font only on that computer which is the original buyer of that font. otherwise you will not be able to access that font file.
How it could be done, Any body can help me in this regard?
