Sympathetic (invisible) ink - records are initially invisible and become visible only under certain conditions (heating, lighting, chemical developer, etc.). One of the most common methods of steganography is to use the classic invisible ink. Typically, the recording process is as follows: first layer - applied to an important record in invisible ink, the second layer - meaningless record visible ink.
