As more people spend more time under the lenses of cameras and in the presence of microphones, and as more footage from those devices goes online, a spoken word crawler with semantic-search capability could allow someone with a smart phone to look up any recorded conversation between two people that's occurred anywhere a microphone was present as easily as any update posted to Facebook.
But don't worry. Because communications technologies make it easy to blurt out words you immediately regret, computer scientists at the University of Washington have created a way to put expiration dates on e-mail, chat messages, and Facebook postings.

As turnover occurs in the network, users take their portion of the encrypted key with them, rendering the message undecipherable.
