USB Key License

[Ahmed_A_2]

Hello

we created a large static library using Intel FORTRAN, winch can be included in a FORTRAN project , and we would like to protect and secure this library using USB key. In other words I would like to write a subroutine in that library to check if the USB key exists or not, in case the key is there the library will continue otherwise it will stop and send a license message for the user. Could any one give me directions or provide me some articles about how to do that?

Any help would be very much appreciated.

Many thanks

Ahmed

There are multiple companies offering such products.  Most of these supply DLLs or libraries assuming you use C#, C++ or VB.  Of course, if they don't supply Fortran wrappers you could write your own.

I did a quick Google search on "Software licensing technology USB" and got a number of hits on such products.

Good hunting!
