Abstract
A method and system for watermarking content utilizing a user device GPU. Embodiments include receiving on a processing server a request from a video server for a video to be played on the user's device. The processing server may extract a set of identifying information, such as user information, from the request for the video. The processing server may further prepare shader software code which is to be executed on a GPU present on the user's device. The code preparation may include creating a watermarking procedure to be executed during playback on the user device. The processing server may further transmit the shader software code to the streaming video server to be transmitted to the user device for execution during video playback.
