We live in the world of information and data. Now every action in our life is eager to get super convenient experience through the Internet. At the same time, it also leaves traces of data in the process. So how to protect consumers has become a problem to be solved. There is no doubt that as consumers, we want to enjoy better services, but how this service needs to be exchanged with my behavioral data is not to expose our privacy. In the corporate world, users' data is gold. So I think it is necessary for strict legislation and law enforcement to effectively protect the privacy of user data. For example, in the EU's general data protection regulations, illegal enterprises face fines of up to 2% to 4% of global turnover. It is hoped that in the future, such laws regulating the use of user data by enterprises will become more and more widely applicable. But we can't stop and hinder the development of technology, so we can only adapt to it. Under the limited protection of law, we should pay more attention to the importance and prevention of personal data privacy, and pay more attention to the impact of data on us in our daily life.
