Re: [tor-talk] Cameras

[Ben Tasker <ben@xxxxxxxxxxxxxxx>]

The problem with blocking the camera in software is that it can then be
unblocked in software (and still potentially without your permission).

There have been examples in the past where others have been able to change
behaviour so that the camera's light doesn't come on to warn the user that
it's recording.

In the absence of being able to disconnect the camera, the only way to be
certain is to physically obstruct the lens, hence the stickers.

But, if you want to find out which process is using the camera (assuming
it's using v4l), you can do something along the lines of

fuser /dev/video0

Which should give you the pid of whatever process is using it.
