ВЫЯВЛЕНИЕ НАРУШЕНИЙ ЦЕЛОСТНОСТИ ЦИФРОВОГО ИЗОБРАЖЕНИЯ ПУТЕМ ИСПОЛЬЗОВАНИЯ СТЕГАНОГРАФИЧЕСКИХ АЛГОРИТМОВ.

In this paper we propose a method for identifying the changes of image completion based on stegano transformation of original image. In the case of using the steganography algorithm that resistant for disturbing influences proposed method provides the possibility of identifying nonoriginal areas of the image, even when image was saved in lossy formats. The developed method allows to allocate a specific method of image completion violations - cloning; identify the cloned area and its prototype; separate clone in the case of absence of post-processing from the original image that has not been done before.
