On November 1, 2021, the personal information protection law of the people's Republic of China was officially implemented. Under the current background of intelligence and informatization, it is urgent to improve the construction of personal information protection legal system and establish clearer rules. Personal information is related to human dignity and freedom. In the big data environment, it is more closely related to personal life, property safety and other rights and interests. According to the statistical report of China Internet Network Information Center, as of June 2021, the overall scale of Internet users in China exceeded 1 billion, and the number of websites and apps exceeded 4.22 million and 3.02 million respectively. However, while the network has brought convenience to people's life, the phenomenon of over range collection, illegal acquisition, unauthorized use and even abuse of personal information has also aroused social concern.

Staff of relevant departments distributed "key points of personal information protection" and other publicity materials, received public consultation, publicized network security knowledge, and enhanced citizens' network security awareness and prevention ability.

Some operators abuse face recognition technology to infringe on the legitimate rights and interests of natural persons, which has aroused the attention and concern of the public.

The personal information protection law makes clear and operable provisions on the personal information processing rules, the obligations of personal information processors and the protection responsibilities of relevant departments for personal information. For the first time, a complete set of systematic personal information protection legal system has been established in China to provide accurate "security locks" for personal information. At the same time, the law forms a useful supplement to the relevant provisions of laws and regulations such as the civil code of the people's Republic of China, the amendment (IX) to the criminal law of the people's Republic of China and the network security law of the people's Republic of China, so as to jointly build a "Golden Bell" for personal information protection. The law is not enough. The protection of personal information is a major project involving more than 1.4 billion people. Only by pooling wisdom and courage, and strengthening diversified governance, can we form a joint force. The regulatory authorities need to further strengthen supervision and strengthen daily supervision; Information collectors should strengthen self-discipline and strictly implement the main responsibility. Individuals should enhance their legal awareness, improve their personal information protection literacy, learn to use legal weapons to safeguard their legitimate rights and interests, and fully realize their rights and obligations in information protection in the implementation of the law.
