Abstract: Disclosed in this application are a method for embedding a watermark in video data and apparatus, a method for extracting a watermark in video data and apparatus, a device, and a storage medium. The method for embedding the watermark includes: acquiring a target image frame in video data; performing time-frequency transformation on the target image frame to obtain target frequency domain data, the target frequency domain data comprising a matrix formed by frequency domain coefficients; changing the frequency domain coefficients in the target frequency domain data according to watermark data to obtain watermarked frequency domain data; performing inverse time-frequency transformation on the watermarked frequency domain data to obtain a watermarked image frame; and synthesizing watermarked video data according to the watermarked image frame.

Abstract: The present disclosure discloses an automatic recharge system and method, and a server, and belongs to a field of online recharge. The system includes: an agent server end on which an automatic recharge program runs, a third-party platform server, and at least one provider server, each provider server providing at least one online recharge service; the third-party platform server generates at least one order and stores the order; the agent server end logs in the third-party platform server by using the automatic recharge program and obtains the order; and the agent server end sends a recharge parameter corresponding to the order to the provider server by using the automatic recharge program, so as to complete an online recharge process corresponding to the order.
