Infinitely repeated games with discounting. What changes if players are allowed to conceal their intensions in imprecise devices?

Abstract: In this note, I show that, if players are allowed to conceal their actions in imprecise devices, then, any feasible payoff vector that dominates the maxmin (modulo some players have equivalent utility functions) payoff vector is sustainable by means of subgame perfect Nash equilibrium of the infinitely repeated game with discounting.
