I'm trying to find a way to implement a security kernel driver (or, if not
possible, a user-mode solution) for microphone usage.
I'd like to be able to do the following:
1. Block selective applications from accessing the microphone.
2. If not possible, block all applications from using the microphone.
3. If not possible, notify the user when the microphone is being used.
Can you please shed some light on what possibilities I have?
