On its face, Facebook's actions seem like a classic case of misappropriation, or the intentional, illegal use of the property of someone else for one's own use or some other unauthorized purpose. Facebook admits in its terms of service that all Intellectual Property content, like photos and videos, belong to you, the user. But the fine print essentially allows Facebook to do what its pleases with such content, with some limitations.

Siden 2006 har advokatfirmaet Simonsen hatt midlertidig konsesjon fra Datatilsynet for å overvåke fildeling på internett, og å samle IP-adressen til folk som bedriver denne aktiviteten.

Darknets, themselves, are nothing new; networks like Tor, FreeNet, and Gnutella are well-established. The HP researchers say Veiled is the same idea, only much simpler: It doesn't require any software to participate, just an HTML 5-based browser.

Their system, dubbed retransmission steganography (RSTEG), relies on sender and receiver using software that deliberately asks for retransmission even when email data packets are received successfully. "The receiver intentionally signals that a loss has occurred.
