Vanishing information

Mysterious article published on RBC. The headline in the style of the yellow press: any data disseminated on the Internet will be able to self-destruct .

Further more up-to-date: The University of Washington has developed software that makes it possible for any information spread by a person on the Internet to self-destruct after a given period of time - it will disappear from all sites and even from foreign mailboxes .

I honestly tried to imagine what kind of technology was there, but I could not. The project is funded by the National Science Foundation, the Alfred P. Sloan Foundation, and Intel Corporation.

Go ahead: Vanish [this is the name of this mega-technology] eliminates data using the churn tool (“mixer”) used in peer-to-peer networks. For each message, if desired, Vanish creates its own secret key. It carries information about the lifetime of the data, which is “embedded” in the message, is an integral part of it and, in addition, can be divided into many parts, thus penetrating even into parts of the message stored on other computers.

Well, and a brilliant conclusion: To save the information sent from Vanish, technically, of course, is possible. For example, the recipient can print the e-mail and save it, you can also take a picture of the text before it disappears.

Dear habrazhiteli, please explain who is in the topic - what kind of nonsense is this next?
