Even though messages and photos are deleted in the Inbox of an email page (got in a computer or a cell phone), they can still exist in the Web as they are passed on by the Web mail services. Anybody can retrieve them and misuse against you. Now a research system, called Vanish gives its users a control over the lifetime of their messages, photos or other personal data that is stored in the Web. With this Vanish these all become unreadable permanently by themselves at a specified timeout. As they are already encrypted by the Vanish and the encryption key for it is lost at the timeout, they self - destruct themselves. So, after this it becomes impossible to decrypt and read the data once for all! Hence, Vanish will be a valuable and useful system tool for all of us soon.
