Abstract
The present disclosure provides systems and methods for video content security and for detecting and preventing unauthorized playback. According to an exemplary method, a device performing a video playback can acquire a set of video frames from a decoder during the video playback, and generate, based on the set of video frames, a first video identifier. The first video identifier can be sent to a server. In response to the server determining that the first video identifier matches a second video identifier stored in the server, the device can receive a list of authorized playback sources associated with the second video identifier. The device can determine whether a source of the video playback is included in the list of authorized playback sources, and control the video playback based on the determination.
