When you mean of privacy tribute , chances are Facebook does not straight off take form to beware . But anonymity researchers are suggesting that social networks may throw the cay to well anonymous online interaction .
existent anonymity tools , such as Tor , work by routing a user ’s internet traffic through a random chemical chain of other computing machine called a electric circuit . Any one individual computer in this tour can only ever see entropy about the motorcar one place ahead of it or one billet behind it . This chemical mechanism keeps the mastermind of the petition anonymous : online natural process very quickly become divorced from their source . Information that was put into the circuit from one machine hail out into the internet from an whole unlike machine , with no way to decipher a course back to the originator . That ’s the theory , anyway .
In reality , however , tracing the originator is reasonably simple . To reverse - engineer the personal identity of a person through the anonymisation meshing , all an interested arrangement needs to do is place a large number of its own machine into the anonymisation mountain chain . The data point then can then be patch together to reveal the source . This is know as aSybil attack .
That ’s a trouble because while Tor is often used for illegal Indian file sharing , on-line anonymity has been crucial – for object lesson , in allowing unassailable communicating during the Arab Spring .
To thwart eavesdroppers , researchers from the University of Texas , the University of California , Berkeley , and the University of Illinois at Urbana - Champaign took reward of a alone prop of Facebook : its ability to plug into you to friend . Their organization , call Pisces , apply graph of social internet connective to make indisputable that only trusted nodes are used to make the random circuit , offer a dependable path to the cyberspace that exclude snoop node .
Pisces ’s reliance on societal connection does confer some disadvantages . First , it wo n’t turn for exploiter without a passably wide social mesh . It also require users ’ social contacts to participate , although the researchers are try on to use friends - of - ally in the cartel web to amend both of these issues .
“ The internalisation of social trust will likely be an significant consideration in the design of the next generation of deploy anonymity systems , ” the researchers say . [ arXiv ]
