Custom Anti Cheat for a number of games

I require a Anti Cheat program to be made, it will be used as a 3rd party AC to be run by players taking part in online gaming competitions. It must check for all known cheats, be secure from hackers & script kiddies. It must also be flexible enough so oher games can be incorporated into the Anti Cheat. Graphics is not a big issue, i would like the finished product to be as small in size as possible.
