Extension and analysis of information hiding method Deep Steganography

Information hiding method Deep Steganography has been implemented. As a result, an extension of the method is proposed in the form of adding $n$ additional hidden layers to the encoded image. This extension allows transmitting more messages in the image container per one transmission session. The properties and metrics of the method have been analyzed, and the results show that this method allows revealing secret messages with SSIM-index accuracy of $56 \%$ on average for the deepest layer for optimal $n=3$ and $82 \%$ for the closest (third) layer with almost imperceptible hiding properties.
