Re: Program protection - can not be copied

I am not sure about that.
If I write a filesystem filter driver to prevent the program from being
copied out,
will the program can be executed properly by system?
User can not read the program, but how does the system can read and execute
the program?

Thank you very much,
Brain

Not really, you could write a filesystem filter that prevents your
application or parts of it to be copied out.

It seems that there is no any direct method to protect the program from
being copied.
The only way to protect the program is doing with some unique ID or
hardware-specific inforamtion.
Right?

Dear expert,

I want to protect my program in CE 5.0.
After installing the program into system, I want the file can not
be copied. Then, user can not copy the program and run on other
device.

Is it possible? And How to archive this solution?
If you put the file inside the OS image it won't be possibile to
extract only the application (unless it's a managed app) from the .bin
file (or from the image on flash).
It's possibile to "download" the image from a device and run it on
another one, but they must be hardware compatible.
If you need to "lock" the image on a specific hardware you'll have to
find a way to put some device-specific information (serial number, MAC
address etc.) in the image but this could be a nightmare to manage in
production.
