Abstract: A ticket authentication method and a ticket authentication device are provided. The ticket authentication method includes the following steps. A first electronic device outputs an e-ticket. A second electronic device acquires the e-ticket. The second electronic device outputs a visible light verification code. The first electronic device acquires the visible light verification code and generates a composite code according to a certification data and the verification code. The second electronic device acquires the visible light composite code, and determines whether the composite code matches the certification data and the verification code. When the composite code matches the certification data and the verification code, the second electronic determines that the authentication of the e-ticket is successful.

Abstract: A system and method for combining light codes and a video are provided. The system includes an editing device and a storage device. The editing device identifies the content of a video to obtain a playback period of a plurality of frames having at least one candidate object in the video. The storage device stores at least one candidate object code and at least one light code symbol, and the light code symbol has a correspondence with the candidate object code. The editing device matches playback period of the frames having the at least one candidate object with the light code symbol, so as to provide a light code output table corresponding to the video.
