Vanish is a research system designed to give users control over the lifetime of 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.

Nice idea, So, I wonder how long before it's nobbled?

[somanyholes]

not sure tbh. It does look good, and cleverly designed. Going to having a good play around with it.

I'm a bit confused, why would you want data you have carefully stored to vanish?

[Rik]

You wouldn't with everything, Bob, but some material you might want to share briefly, eg a confidential email exchange.

[talos]

AH! Yes, hadn't thought of that

Sounds like it might be useful for some data but surely it's possible to copy the unencrypted data when reading it, to a file that will not self destruct.

[Rik]

You would think so, John.
