The methods of protection of printed documents latent images are promising in protection are shown. The main threats to the print and electronic media and types of fraud are studied. The basic principles of protection which ensure the reliability and integrity of the document containing hidden element are constructed. A study of the scanned images found that the main document does not meet up. Latent images can securely protect paper documents. The system of equations to calculate curvilinear patterns, where the optical formula of acceleration and periods of fractals stored in its simplest form, is introduced. There is a need to create new types of protection of printed documents since the means and methods of fraud are becoming more common.
