  • Patent number: 10878461
    Abstract: Embodiments of the present disclosure disclose a method and an apparatus. The apparatus includes interface circuitry and processing circuitry. The processing circuitry obtains attribute information of multimedia information associated with a multimedia provider. The attribute information includes website information of a website used to display the multimedia information and identifier (ID) information associated with the multimedia information. The processing circuitry generates a machine-readable identification code to be scanned by a user device of a user based on at least the website information. Based on the ID information, the processing circuitry obtains a first image corresponding to the multimedia information. The processing circuitry determines an image area in the first image in which the machine-readable identification code is to be inserted. The processing circuitry inserts the machine-readable identification code into the image area to generate a second image.
