Programme Product Development for Information Protection on the Ground of Films With Hidden Latent Images

The authors developed a new data protection method, which is based on security printing. This method can be employed for protecting financial documents such as banknotes and securities in general. The protection method creates hidden messages or images, which become visible on counterfeited documents. The way of increasing the efficiency of digital image detection and localization of unauthorized interference “copy paste”.

Method of forming latent image to protect documents based on the effect moire

Analysis of modern methods of information protection based on printed documents. It is shown that methods of protection from moiré effect provide reliable and effective protection by gaining new protection technology that is displayed in the optical acceleration motion layers and causes moire in fraud. Latent images can securely protect paper documents. Introduce a system of equations to calculate curvilinear patterns, where the optical formula of acceleration and periods moire stored in its simplest form.
