"This [Data] Will Self-Destruct in Five Seconds."

"Vanish is a research [?] system designed to give users control over [their] . . . personal data stored on the web or in the cloud. Specifically, all copies of Vanish encrypted data — even archived or cached copies — will become permanently unreadable at a specific time, without any action on the part of the user or any third party or centralized service.

"For example, . . . a user can create an email, a Google Doc document, a Facebook message, or a blog comment — specifying that the document or message should "vanish" in 8 hours. . . . after that timer expires, nobody can read that web content — not the user, not Google, not Facebook, not a hacker who breaks into the cloud service, and not even someone who obtains a warrant for that data. That data — regardless of where stored or archived prior to the timeout — simply self-destructs and becomes permanently unreadable.

"An enormous amount of private data is now stored on the web or in the cloud, outside the end-user's control. . . . Web-based email systems may back up the message, potentially forever, even if you delete it. Similarly, when you send a message via Facebook or create a Google Doc, you have no idea where and for how long copies of your data will be stored.

" . . . . There are known examples of data remaining in the cloud long after users explicitly request that data's deletion. Private data could be exposed by accidental misconfigurations on a web service, be compromised by hackers, or be used in legal proceedings.'"


(Emphasis supplied; via boingboing, via Ben – thanks!) More at Vanish.

Of course, this means the gummint can "vanish" its own records, too – but lately there's been little to stop them from doing that the old-fashioned way.
