The Steganographic Method of Introducing Additional Information, Resistant to Transcoding and Conversion

In many current videos is necessary to include hidden information. It can be done with the use of steganography. Steganography is based on the limited capabilities of human senses, which is why people are not able to distinguish minor variations of colors. Based on the research of limit to human vision, here we offer a new method and test equipment for research and measure the characteristic of hiding information in the digital image. The presented steganographic method is based on Discrete Wavelet Transform (DWT) for the transition to the lower frequency domain. The main goal is to embed information in a digital image so that both the message and the fact of its presence are hidden. The presented method reflects the internal mechanisms of the visual system and is convenient for describing the process of image perception. The experimental results were compared with other methods and proved to be satisfactory
