Natural mouse movements and defeating bot detection systems like captchas

[chants]

What is this flag specifically? But this would be for desktop or DX apps I imagine not browser or store apps.

Also what about in the web browser window - I imagine that javascript and such cannot detect directly. Probably SendInput is okay here. I think in sophisticated situations, they are recording detailed timing and mouse position information, and then matching it against a classification algorithm which is trained to determine robots verse humans - totally empirically.

And modifying DOM in browser windows could definitely be detected by introspection or reflection techniques. Reading the DOM might even be detectable too though I have not much knowledge about that - if it could do something like constantly modifying the DOM and measure time too see if its too slow from monitoring, or if by some other tricks.

I was looking into chess websites which are detecting cheating now by monitoring and recording the mouse. I think with timing and mouse data, 99.9% can be detected. But of course, nobody even realizes this as they have kept it very secretive as its the last remains of their business to defend against this. But we are in a new computing era. All you have to do is visually grab the board, line detection (9x9 grid), piece detection using shape recognition, or shape areas, etc, single move detection heuristics, then send it off to an analysis engine. Further to not always make engine moves, make good moves or blunders or inaccuracies when its even or when winning from time to time deliberately. Use a time per move algorithm with randomization and logarithmic decay as it goes towards running out of time when in a complex position to avoid predictability but in trivial positions instant moves. At this point, its impossible to prove anything if you can move the mouse in human-like ways - or just draw an analysis window in a desktop app and hand make the moves. Unfortunately these sites are quick to ban an account and IP address - after running invasive monitor tricks with 30% CPU . It is a pretty big business. But given that grandmasters already have secret apps doing exactly the sophisticated set of techniques I describe and are certainly cheating, I think its time for some indistinguishable robot/human type games to have a strong solution open sourced.
