The invention discloses a compressive sensing-based
adaptive video information hiding method, which is characterized by comprising the following steps of: a, framing a video file by using shot as a unit; b, taking the first frame of each shot as a
key frame; c, establishing an
image texture classification model to obtain a texture classification model mark of each
key frame; d, determining a texture category of each
key frame and determining whether the key frame is a texture region, or a smooth region or between the texture region and the smooth region; e, selecting an
algorithm and determining insert depth; f, inserting secret information, i.e., inserting the secret information in a
coefficient matrix; and g, synthesizing a video file. According to the video
information hiding method, the secret information can be adaptively inserted under the condition that the entire video file is not required to be decompressed, so that the ornamental value of the video is not affected, and the method has the advantages of small amount of calculation, high information
steganography efficiency, small influence on the video and good secret information safety. The method can be widely applied to various fields such as copyright
authentication, pirate tracking and
secure communication.
