Linux USB Video Class (UVC) Driver with RECORD & REPLAY modes

A proof of concept for spoofing face verification software and the like.

This repository contains modifications to the Linux (6.9.5) uvcvideo driver, with the modified files residing in the drivers/media/usb/uvc directory. It also contains scripts in Python & Bash for the spoofing workflow.

Example Usage

1. Run ./inst.sh to install the kernel module, and replace the default uvcvideo driver.
2. Run ./switchrecord to switch the module to RECORD mode.
3. Turn on the camera, e.g. via Cheese. Multiple streams possible.
4. Run ./styx.py k2u recorded to transfer the frames from kernelspace to userspace (as a nested directory of images named recorded).
5. (Opt.) Run ./mirror.sh recorded/ mirrored/ to mirror (horisontally flip) the frames. This will produce a directory mirrored.
6. Run sudo ./styx.py u2k mirrored to transfer the modified frames back to kernelspace.
7. Run ./switchreplay to switch to REPLAY mode.
8. Turn on the camera again. Now the frames should be mirrored.
