Abstract: A voucher verification auxiliary method is provided, including: when a user device is approaching a voucher verification auxiliary device, generating an encryption key for the user device to encrypt voucher data with the encryption key to generate first encrypted data; reading and decrypting the first encrypted data to obtain the voucher data; encrypting the voucher data to generate and transmit second encrypted data to a verification center; decrypting the second encrypted data to obtain the voucher data, generating a verification result after verifying the voucher data, encrypting the verification result to become third encrypted data, and transmitting the third encrypted data back to the voucher verification auxiliary device; decrypting the third encrypted data to obtain the verification result; transmitting the verification result to a voucher receiving terminal. A voucher verification auxiliary device and a voucher verification auxiliary system are also provided.

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.
