Right now, kloak only works for obfuscating keystrokes. Anonymizing mouse pointe…r motion and click behavior, without affecting user experience too much, requires some further research. The same technique (of randomly sampling the delay and adjusting distribution bounds to ensure event order, described in [1]) could be applied to mouse click events (and other I/O peripherals with buttons, like joysticks or controllers). There's more difficulty in obfuscating the "shape" features of the pointer motion. This has to do with that the mouse motion being a continuous rather than discrete process. A solution might have to be some combination of UI design and obfuscation. For example, grab the mouse device and draw the true pointer location in real time, while the obfuscated pointer (which lags behind the true pointer) quickly follows in a random path, eventually stopping where the true pointer is located. The obfuscated pointer events would be what is written to the uinput device, while kloak draws the true pointer location on screen. [1] https://arxiv.org/pdf/1609.07612.pdf
