  • Patent number: 10769836
    Abstract: A method and an apparatus for establishing a coordinate system and a data structure product are provided. The method includes following steps: obtaining at least one layer related to an arrangement of an indoor space to generate a layout pattern in a 2D or 3D model; obtaining locations of positioning devices located within the indoor space and labelling the locations in the layout pattern; dividing the layout pattern into multiple view tiles according to a unit area or a unit volume for displaying the layout pattern; dividing a portion of the layout pattern around the labelled positioning devices into multiple positioning tiles according to the labelled locations of the positioning devices; and selecting at least one representative point of the view tiles and the positioning tiles as a reference point to define a reference frame and establishing the coordinate system based on the reference frame.

  • Patent number: 10748053
    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.

  • Patent number: 10510377
    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.

  • Publication number: 20190199522
    Abstract: The present disclosure provides a system and a method for communication service verification and a verification server thereof. The method includes: obtaining a light code from a light code transmission device through a user device; demodulating the light code by the user device to generate a cipher; receiving a service request sent from the user device by a service system server; receiving a verification request sent from the user device or the service system server by a verification server; and retrieving a decryption key by the verification server based on the verification request, so as to decode the cipher in the verification request using the decryption key and obtain a decoding result.
