Abstract: Personal information breach knows no borders, and foreign countries also pay great attention to the issue of personal information breach, adopting a multi-pronged approach to stipulate personal information breach notification,registration and personal information security protection systems, increasing the penalties, and launching class actions to compensate victims countermeasures such as losses. China has always paid great attention to the issue of personal information breach, and has continuously improved the rules and regulations governing personal information breach. It has formed a closed-loop management mechanism by stipulating personal information security obligations (preventing the source) and establishing a personal information breach notification system (end of control). At the same time, law enforcement work related to personal information protection is gradually being rolled out, and supervision work has achieved certain results. However, in the process of managing personal information breach, there are problems such as insufficient supervision and difficulty in personal rights protection. It is recommended that China promote the safety management of personal information breach in the industry and implement the public interest litigation mechanism, and take multiple measures to achieve effective management of personal information breach.
