In game theory, an asymmetric game where players have private information is said to be strategyproof (SP) if it is a weakly-dominant strategy for every player to reveal his/her private information. It is also called truthful or dominant-strategy-incentive-compatible (to distinguish it from other kinds of incentive compatibility).
