From the perspective of criminal law, there is no clear definition of "candid camera". However, in the General Principles of Civil Law and related judicial interpretations, there are clear provisions on the protection of privacy. The scope of privacy right includes: 1. Basic information and materials related to my body, identity and characteristics; 2. Social information and materials related to one's own life experience; 3. Some information and materials related to personal fields and their social activities. Privacy also involves privacy. For example, the photos of women taken in the news background are related to the body. These are all within the scope of legal protection. Generally speaking, you should greet others when shooting in public. If they don't agree, you can't shoot. In addition, sneak shots are sneak shots, which means that the person being photographed has no intention at all and has no way to acquiesce, so it is illegal to sneak shots in public.
