USB Key Protection

[Jarvis]

I would like to sell an application someday, but I am concerned about how to protect it from being duplicated.

A CAD package I used to own came with a USB key that had be inserted before you could operate the software.

Does this system still exist?

Is it a viable "lock" on the software?

Where would I learn more about this?

Thanks,

Jarvis

Yes there is a solution available for interfacing a USB dongle with FMP and a plugin by 24u Software

Thanks Stephen!

Just what I was looking for.

I also have found "exeshield" to use dongles and it is quite well as far as security goes. I have used it for 2 years.

I have often wondered how easy it would be to break one of these systems by breaking it at the FileMaker end. That's probably a laboratory exercise thatought to be undertaken.

USB Stick protection.

I tried using the USBSentry system for protecting my files to end users.

However I would caution anyone from using their system. They never provided me with a working system and refused to refund my payment. Instead I was forever locked into their PlugIn operating in the Demo mode which was unacceptable.

Addendum : After several email exchanges I was given the proper registration codes. The instructions were somewhat confusing and they promised to make them clearer in the future. So far it all works as intended.

I had also looked into the 24u HASP Plugin using Aladdin systems keys. This is more expensive and complex requiring a driver to be installed. It can do much more but for just a simple key verification is overkill.
