The invention discloses a winebottle anti-forgery system for opening a winebottle cap through the Internet, which consists of an ID (Identity) radio frequency coded lock winebottle cap, an electronic winebottle opener and a server system. The ID radio frequency coded lock winebottle cap is packaged at a winebottle opening. The winebottle anti-forgery system is characterized in that the electronic winebottle opener is connected with the server system through the Internet. When the winebottle is needed to be opened, an opener takes out the electronic winebottle opener and opens a power supply switch of the electronic winebottle opener to be connected with the Internet and confirm signal connection with the server system. The opener holds the electronic winebottle opener to scan the ID radio frequency coded lock winebottle cap to obtain ID radio frequency codes of the ID radio frequency coded lock winebottle cap and transfers the ID radio frequency codes to the server system. The server system compares the ID radio frequency codes of the winebottle cap with each ID radio frequency code in an ID radio frequency code database stored by the server system so as to find out a corresponding ID radio frequency data record through comparison. If the server system detects that the corresponding ID radio frequency data record is in normal legal state, the server system sends an opening command to the electronic winebottle opener. After confirmation of the opener to open the winebottle cap, the system sends the opening command to open the ID radio frequency coded lock winebottle cap.
