Similarly to the dubious goals panel we have in the Premiership, there should be committee of perhaps 3 ex-players who look back at incidents from games which researchers have picked out, where they believe any form of cheating (or attempt at) may have taken place.
At this point the panel then decide if a player(s) has in any way attempted to fool the referee, this will mostly deal with diving. The panel have to be 100% sure that a player has actually dived and has not lost their footing/slipped/jumped out of the way of contact (the latter behaviour is fine as long as the player doesn't appeal for a foul, this would be deemed as cheating). Therefore the panel have to be unanimous in their decision.
Once a player has been found guilty the discipline has to be heavy, it is clear that we cannot trust some players to play our game in the right spirit. A personal suggestion would be a 3 game ban for each individual who has attempted to to con the referee. This is the same as an automatic red card, and in my opinion diving is far worse than a lot of challenges that players receive straight reds for. The player can only receive one ban a game though (ie even if the player has dived 5 times in a match he can still only receive a 3 match ban.) Fines are irrelevant as a detterent in the modern game, although I'm sure the governing bodies would still implement them as they no doubt receive sizable incomes from this form of punishment.
Top level football has become a farce of late, and certain clubs/nations have become unbearable to watch. Being from a background where it would be embarrassing to show you are hurt from a challenge, I find play acting disgusting and disgraceful to watch, players who roll around acting as if they have been shot when replays show little or no contact are not fit to play the game, nevermind get paid for it. The argument that this is acceptable due the high pressure to succeed top footballers face, does not wash with me.
This action needs to be undertaken immediately. I am in continuous bemusement that something has not been done already. Until the governing bodies do pull their head out of their ****'s, the media need to do as much as possible to name and shame those guilty, perhaps continuous ridiculing of these cheats may alter their behaviour. In this vain, now follows a list of players who spring to mind who persistently dive/cheat/feign injury:
Drogba, Lehman, Robben, Gilardino, Joe Cole, Vieira, Diouf, Pires, Andy Johnson, Pretty much the whole Portugal team from the last world cup. The fact that so many players from one team repeatedly dive, cheat and hound and harass referees, surely paints their manger in anything but a positive light, thats right, you cheat, Jose Mourhino.
