Traceable electronic paper print adding method for offline video

The invention provides a traceable electronic paper print adding method for offline video. The method comprises the following process: (1) performing feature coding on feature information of a storage source computer of the offline video or feature information of a channel from the storage source computer to a target computer, and generating an electronic paper print with feature coding information by using the code; and (2) adding the electronic paper print to each frame of the offline video to obtain offline video added with the electronic paper print. The method can be used for tracking the play source of the offline video; the video to be played is added with an electronic paper print, the electronic paper print includes the feature of a computer or a channel of the video, the electronic paper print has robustness in the transmission and playing process, the electronic paper print is still valid even if in a phone shooting offline manner, and the electronic paper print can be detected via a feature detection technology when in need to determine which computer or channel the video flows out of.
