user38: Is there such thing as a chess playing signature? Meaning within x-amount of games the identity of a player is known based on the skill and game play of the player.

user7281: I like to add, that recently Magnus Carlsen visited Bill Gates and Mark Zukerberg and I think it came into the discussion to formalize the interconnect of a heart pulse sensor (they used wristband) during a chess match. Indeed, they had an actual simultaneous match with Magnus and many participants where all the players including Magnus wore a heart pulse sensor wrist band. 
I believe that the inclusion of a "time in-between moves" and a heart pulse sensor data can signature a player by by then. The DGT Corporation are the official manufacturers of DGT boards + clock thru USB interconnect and in the best position to integrate all these needed sensory peripherals. 

user70: Unlikely.  The first several moves of any game by notable players are all book.  Thereafter, people who play notable games are able to play superb offensive and defensive moves.
Now, if you see some crazy sacrifice, you might think Anderssen or Tal is playing this game. Similarly, if you see some superb positional move, you might think Petrosian or Karpov is playing.
But to see a game played by any of the top 20 players of all time and pick out who was moving the pieces based upon their styles, I can't imagine it.  There simply isn't the 'bandwidth' for such an individual signature in chess beyond someone playing more positionally or more tactically; that's pretty broad-brush stuff.
