Disable the built-in camera in Linux

First, find the webcam driver using the following command:

$sudo lsmod | grep uvcvideo

Sample output:

Uvcvideo 114688 1videobuf2_vmalloc 16384 1 uvcvideovideobuf2_v4l2 28672 1 uvcvideovideobuf2_common 53248 2 uvcvideo,videobuf2_v4l2videodev 208896 4 uvcvideo,videobuf2_common,videobuf2_v4l2media 45056 2 uvcvideo,videodevusbcore 286720 9 uvcvideo,usbhid,usb_storage,ehci_hcd,ath4k,btusb,uas,ums_realtek,ehci_pci

Here, uvcvideo is my webcam driver.

Now, let's disable the webcam.

To do this, edit the following file (if it does not exist, just create it):

$sudo nano / etc/modprobe.d/blacklist.conf

Add the following line:

# # Disable webcam.blacklist uvcvideo##Disable webcam

This line of work is not necessary. I added it to make it easier to understand.

Save and exit the file. Restart the system for the changes to take effect.

To verify that the webcam is really disabled, open any instant messaging program or webcam software, such as Cheese or Guvcview. You will see the following blank screen.

Cheese output:

Guvcview output:

Did you see that? The webcam is disabled and cannot be used.

To enable it, edit:

$sudo nano / etc/modprobe.d/blacklist.conf

Comment out the lines you added earlier.

# # Disable webcam.#blacklist uvcvideo

Save and close the file. Then, restart the computer to enable the webcam.

Is that enough? No, no. Why? If someone can access your system remotely, they can easily enable the webcam. So it's a good idea to cover it with tape when not in use or unplug the camera or disable it in BIOS. This method is used not only to disable the built-in camera, but also for the external webcam.
