Modeling and development of a system for implementing and recognizing latent images

If earlier the problem of authenticity concerned only printing products (securities, documents, tickets, money, etc.), today the protection of documents presented in digital form (scanned documents, photographs and other multimedia documents) is no less relevant. Therefore, the creation of systems for embedding hidden information in secured documents by various methods is an urgent task, because It will allow you to protect documents, as well as in disputed situations, confirm their authenticity or copyright. In this work, a mathematical model of the system for embedding and recognizing hidden images is developed, which differs from its analogues in the possibility of expanding the many used functions for embedding and recognition. In contrast to the well-known unified model of a system for embedding information in digital signals, a model is proposed that allows implementing the modular principle of constructing a system for recognizing images containing hidden information introduced by various methods. Also, on the basis of the constructed system model, an information system for the implementation and recognition of hidden images, consisting of three interconnected software modules, was developed. This system is a graphical shell for models developed in MATLAB. This approach allows you to integrate the system, add new ones or make changes to existing modules, make changes to the developed model.
