First of all, malicious disclosure of personal information will be severely punished and fined. In the data age, information has become an important strategic resource to promote the development of national economy. New technologies and applications of the Internet are emerging one after another, and the cyberspace is more open. The improvement of information flow and frequency of use improves the utilization efficiency of information resources, but it also weakens citizens' ability to control information security. In cyberspace, a large amount of personal information is maliciously stolen, sold and used. Information leakage has become an important factor that hinders the healthy development of the Internet. Good online habits are the most important factor for consumers to protect personal information security. In recent years, more and more consumers have been deceived by phishing websites and bad websites. When searching for e-commerce, consumers should carefully check whether it is official website, and whether the domain name and webpage are slightly different from those of official website. If they log on to phishing websites, they will maliciously record the accounts they entered in the background and collect or resell all personal information when completing the transaction.

Secondly, malicious disclosure of personal information may be subject to criminal punishment if the circumstances are serious. For online consumers, in addition to relevant national laws and regulations and technical protection measures provided by e-commerce websites, self-protection awareness, good online habits and necessary online shopping safety technical knowledge are three indispensable tools for personal information. Consumers should start with the details and pay attention to the possible impact and consequences of each step of their online shopping process.

According to Article 253 of China's Criminal Law, whoever, in violation of the relevant provisions of the state, sells or provides personal information of citizens to others, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention, and shall also or only be fined; If the circumstances are especially serious, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and shall also be fined. When we register, users can properly use false personal information or choose not to provide unnecessary information and pay more fees without affecting basic services. Pay attention to personal sensitive information. In the process of communicating with the seller and asking about the products, please be careful not to reveal too many personal preferences. If the other party often sends promotional messages or calls back, it should remind you that you have been cheated. If necessary, you can report to the customer service of the e-commerce platform that the other party has caused some harassment to yourself and learn to safeguard and protect your rights and interests.
