Однако среди исследований есть примеры, подтверждающие, что диффузионные модели менее конфиденциальны, чем генеративные модели, такие как генеративные состязательные сети и растущее семейство их модификаций. Обнаруженные уязвимости требуют глубокого изучения различных аспектов безопасности. Это особенно важно для таких чувствительных областей, как задачи анализа медицинских изображений и их практическое применение. В статье рассмотрен метод обнаружения шаблонов изображений, представленных на сгенерированных изображениях, которые потенциально могут быть идентифицированы на реальных изображениях компьютерной томографии пациентов с туберкулезом лёгких. Метод включает следующие основные процедуры: корреляция пар сгенерированных и реальных изображений для предварительного выбора пар, которые предполагают дальнейший анализ; вычисление статистики корреляции с использованием прямого и обратного преобразований Фишера; выполнение аффинной регистрации изображений и расчет оценок парного сходства; нелинейная (эластичная) регистрация изображений и повторный расчет оценок сходства для выделения наиболее похожих/несхожих областей изображения.</p></abstract><trans-abstract xml:lang="en"><p>Generative diffusion models are a well-established method for generating high-quality images. However, there are studies that show that diffusion models are less privacy-friendly than generative models, such as generative adversarial networks and a growing family of their modifications. The discovered vulnerabilities require in-depth study of various security aspects. This is especially important for sensitive areas such as medical image analysis tasks and their practical applications. The paper describes a method for detecting image patterns presented in generated images that can potentially be identified in real CT images of patients with pulmonary tuberculosis. The method includes the following main procedures: correlation of pairs of generated and real images to pre-select pairs that involve further analysis; calculation of correlation statistics using direct and inverse Fisher transforms; performing affine image registration and calculating pairwise similarity scores; nonlinear (elastic) image registration and recalculation of similarity scores to highlight the most similar/dissimilar image areas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диффузионные генеративные модели</kwd><kwd>компьютерная томография</kwd><kwd>сохранение конфиденциальности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diffusion generative models</kwd><kwd>computed tomography</kwd><kwd>privacy preserving</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">Koshino K., Werner R.
