Technology innovation is of special significance for customs to guard the defense lines of law enforcement and integrity，and to construct clean customs. In recent years，customs integrated technology into prevention and punishment of corruption，weaved a technological anti-corruption net with Early Warning and Processing System towards customs’ enforcement of law as its core，kept a close eye on the process of power operation，recognized integrity risks at early stage，ensured custom regulations be obeyed without harming the efficiency of custom clearance，and achieved the “win-win” effect that punish smuggling and corruption simultaneously.
