По данным PhysOrg, появилось программное обеспечение, которое позволяет обойти защиту графическим ключом lisinopril dosage. На это требуется не более пяти попыток. Программное обеспечение было создано на основе исследований Ланкастерского Университета, Китайского Северо-Западного Университета и Университета Бат. Оно анализирует движение человеческих рук во время разблокировки смартфона.

Анализ можно проводить с помощью камеры смартфона, направленной на пользователя устройства практически с любого ракурса и на расстоянии до 2,5 метров. Полученное изображение обрабатывается с помощью алгоритма, который выдает несколько возможных вариантов графического ключа, используемого владельцем смартфона. Любопытно то, что чем сложнее графический ключ, тем проще для алгоритма его разгадать, так как пользователь будет совершать больше движений, что дает больше данных для анализа.

Из 120 графических ключей, установленных разными пользователями, таким образом удалось разгадать 95 процентов, сделав не больше пяти попыток. Лучший способ защититься от такого взлома — это прикрывать свою руку во время разблокировки устройства либо выбрать другой способ защиты персональных данных.
