Предлагается новый подход, позволяющий с достаточно высокой долей вероятности определить наличие встроенной скрытой информации в тексте. Суть метода состоит в том, что извлекаемое из текста сообщение проверяется на случайность при помощи теста хи-квадрат. Случайность извлечённого сообщения означает наличие внедрения.</p></abstract><trans-abstract xml:lang="en"><p>This article is about a steganalysis method of text data. It proposes a simple and effective approach to detect the presence of embedded information in text files. A message extracted from the text is checked for randomness by means of chi-square test. The method is based on the fact that message randomness reveals the presence of embedding.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стеганография</kwd><kwd>стегоанализ</kwd><kwd>стеготекст</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steganography</kwd><kwd>steganalysis</kwd><kwd>stegotext</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">Рябко Б.
