In recent years， China has made great achievements in the opening of judicial data， but the protection of personal information with the opening of judicial data has not yet attracted enough attention in the practical and academic circles.

In the opening of judicial data， we should formulate unified personal information protection system specifications， clarify the scope of personal information protection， set up special personal information protection organizations， build technical processing standards to protect personal information， and improve the security mechanism of the rights of personal information protection.
