Countdown destruction of your data: take the control

Would you like to get more control over personal data stored on the web?
Researchers have found the way to give users self-destructing computer data.
The answer is in a prototype system called Vanish that will let users create any kind of data like documents, emails and even blog posts creating a deadline . After the specified time limit, the encryption keys will be destruct and it won’t be available to anyone even the author wich produced that document.
The data won’t be read by Google, Facebook, Twitter . Using the Vanish Firefox plug-in, a user can write an email, a Google Document document, a social network post message, specifying that the document should vanish in a specified number of hours.
You can download and install Vanish, but the researchers advice that there may still be bugs. They are ask users to treat it with paying attention, and report bugs and vulnerabilities.
