METHOD OF INCREASING THE SECURITY OF DIGITAL MEDIA CONTENT BASED ON THE USE OF IDENTIFICATION NUMBERS
The article deals with the problem of embedding additional information into a video stream to protect the author’s (not distorted) content. The proposed method is based on the introduction of additional information blocks in the area of the video stream, which remain unchanged during transcoding. This method is based on the principle of observing the effect of changing the luminance component on the container during its copying, extracting and changing key frames. The paper identifies and describes the discrepancies in the values of the extracted and newly formed luminance components during the reverse formation of the RGB color model. An example of embedding additional information into a generated stegocontainer using MPEG-4 and H.264 video codecs using the developed software is given. Possible special filler tags that can be embedded in a video stream are considered.
