Just like some common electronic products that can access the Internet, customers' privacy may be leaked. When we use these products to surf the Internet, we should be careful not to leave passwords on dangerous web pages and not to disclose telephone numbers and personal information to others. However, when someone borrows a mobile phone or computer from us, try to refuse them. If it really doesn't work, you can watch and don't let them open unknown web pages and websites.
When we are outside, we must carefully check whether pinhole cameras are installed in cracks in walls, ceilings and cartons. According to the principle of infrared photography, the indoor light source can be turned off to find out whether there is a suspicious infrared beam. When choosing a hotel, try to choose a hotel with a good reputation, don't be greedy and cheap, and stay in a hotel with security risks.
As the saying goes, there is no need to harm people, and there is no need to prevent people. When we associate with people, remember not to be too close and be wary of people. Try not to let people enter the private field, and don't let others privately control our personal belongings. When strangers ask us to join a certain group or organization, we must ask what their purpose is in advance, keep a high degree of vigilance and never be cheated by others.
So, do you know any other situations that may reveal privacy?
