"Hello, may I ask if this is Ms. Gu? We are a children's photography store near your home and have customized the Baobao Hundred Day Package for you. The discounts are now very strong..." In February 2023, Ms. Gu, who lives in Xinbei District, Changzhou City, Jiangsu Province, was still immersed in the joy of being a new mother and frequently received various sales calls. What made her uneasy was that the other party had precise access to important information such as the child's birth hospital, date of birth, gender, and parents' names and phone numbers. Out of a sense of protection for her child and family, she immediately reported the case to the public security organs. The most direct and effective way to cut off the black industry chain of newborn information trafficking is to rely on the law. In recent years, China has successively established a legal barrier for the full chain protection of personal information rights through the Civil Code, Criminal Law, and specialized legislation. The Civil Code has made systematic provisions on the protection of personal information in the civil field; The Personal Information Protection Law has refined and improved the principles of personal information protection and the rules for personal information processing; The Criminal Law specifically stipulates the crime of infringing on the personal information of citizens, providing a powerful weapon for severely punishing the "black hands" who extend their personal information to citizens. With the improvement of the legal system, many suspects who sell newborn information have been punished in accordance with the law. To prevent the leakage of newborn information, relevant websites and medical units must take important responsibilities. For newborn information websites, it is necessary to establish a normalized mechanism for personal information protection, promptly repair technical vulnerabilities, eliminate security risks, and guide medical units to regularly update account passwords to ensure the security of newborn information. For medical institutions, they should improve institutional construction and standardized management in accordance with the requirements of the Special Action Plan for Patient Safety (2023-2025) issued by the National Health Commission, and strengthen the protection of personal information at the source. At the same time, relevant personnel should also strengthen education on the rule of law and the construction of medical ethics and medical conduct. The fortress must not be dismantled from within. Once an "insider" is found to sell information, it must be severely punished in accordance with the law. Only in this way can we safeguard the information security of newborns. (Lai Xin She)
