Предложен новый подход к проектированию стеганографической системы, основывающейся на трёх основных методах – внедрение частей разделенного секрета в изображения с возможным, в дальнейшем, извлечением секретной информации, проверка подлинности частей секрета, самовосстановление данной системы безопасности. Такая система обеспечивает большую степень защищенности и безопасного хранения данных. Windows-приложение, которое реализует предложенную стеганографическую модель, не имеет аналогов и отвечает всем требованиям, поставленным к стеганографическому программному обеспечению.</p></abstract><trans-abstract xml:lang="en"><p>An effective method for solving data security problems is proposed. A new approach to the design of steganographic system based on the three basic methods - the introduction of parts of a shared secret into images with the possibility of further extraction of secret information, authentication of parts of a secret, self-healing of this security system. Such a system provides a greater degree of protection and secure data storage. The Windows application implements the proposed steganographic model, has no analogues and meets all the requirements set for steganographic software.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>защита данных</kwd><kwd>информационная безопасность</kwd><kwd>стеганография</kwd><kwd>дискретное косинусное преобразование</kwd><kwd>схема разделения секрета</kwd><kwd>(k</kwd><kwd>n)-пороговая схема</kwd><kwd>блокчейн</kwd><kwd>реконфигурируемая система</kwd><kwd>программное обеспечение</kwd><kwd>технология .NET</kwd></kwd-group><kwd-group xml:lang="en"><kwd>data protection</kwd><kwd>information security</kwd><kwd>steganography</kwd><kwd>discrete cosine transform</kwd><kwd>secret sharing scheme</kwd><kwd>(k</kwd><kwd>n)- threshold scheme</kwd><kwd>blockchain</kwd><kwd>reconfigurable system</kwd><kwd>software</kwd><kwd>.NET technology</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Генкин, А.
