Offline video tracking method based on electronic paper-prints

The invention provides an offline video tracking method based on electronic paper-prints. The offline video tracking method comprises an electronic paper-print overlaying process and an offline tracking process, and comprises the following steps of: performing feature coding on feature information of a storage source computer of a video or feature information of a channel from the storage source computer to a target computer, and generating an electronic paper-print having feature coding information by utilizing coding; overlaying electronic paper-prints to each frame of the video, so that a video to which the electronic paper-prints are added is obtained; detecting the video, and extracting the electronic paper-prints of the video; and, decoding the electronic paper-prints, and extracting the feature coding information therein. The offline video tracking method provided by the invention can be used for tracking a playing source of an offline video; the electronic paper-prints are added to a video to be played; the electronic paper-prints include features of a video playing computer or channel; the electronic paper-prints have robustness in a transmission playing process; if necessary, the electronic paper-prints can be detected through a feature detection technology; and thus, an outflow source can be determined.
