The UK government is considering the mass surveillance and retention of all user communications on social-networking sites including Facebook, MySpace, and Bebo.
Home Office security minister Vernon Coaker said on Monday that the EU Data Retention Directive, under which ISPs must store communications data for 12 months, does not go far enough. Communications such as those on social networking sites and instant messaging could also be monitored, he said.
"Social-networking sites, such as MySpace or Bebo, are not covered by the directive," said Coaker, speaking at a meeting of the House of Commons Fourth Delegated Legislation Committee. "That is one reason why the government are looking at what we should do about the Intercept Modernization Program, because there are certain aspects of communications which are not covered by the directive."
Under the EU Data Retention Directive, from the March 15, 2009, all UK internet service providers (ISPs) are required to store customer traffic data for a year. The Intercept Modernization Program (IMP) is a government proposal, introduced last year, for legislation to use mass monitoring of traffic data as an anti-terrorism tool. The IMP has two strands: that the government use deep packet inspection to monitor the web communications of all UK citizens; and that all of the traffic data relating to those communications are stored in a centralized government database.
The UK government has previously said that communications interception was "vital", and has hinted that social-networking sites may be put under surveillance. However, responding to a question from Liberal Democrat MP Tom Brake, Coaker said that all traffic data on social-networking sites and through instant messaging may be harvested and stored.
"The honorable member for Carshalton and Wallington will also know the controversy that currently surrounds the Intercept Modernization Program," said Coaker. "I look forward to his support when we present Intercept Modernization Program proposals, which may include requiring the retention of data on Facebook, Bebo, MySpace and all other similar sites."
Deep packet inspection, the second strand of the IMP, involves intercepting and examining the contents of all data packets that flow over a network. In Monday's meeting, Coaker said the government still intends to have a consultation on whether to inspect and then store all internet traffic data in a centralized government database.
"What is the point of having a consultation if, as the honourable gentleman implies, the government have already made up their mind to have a central database?" said Coaker. "We have not made up our mind. We have said we will consult on a variety of options."
Opposition to the government's IMP proposal has been fierce. Cambridge University computer security expert Richard Clayton told ZDNet UK on Wednesday that the government proposal to monitor social-networking traffic was "extremely intrusive".
"The question is whether it's necessary or proportionate, and the short answer is no, it doesn't look that way," said Clayton. "If the government wants to make us safer, having a few more police on the electronic beat would be a good idea."
Clayton said that the problem for the government is that the Data Retention Directive only applies to data held by internet service providers, but that a large number of people don't use ISPs' systems to communicate, instead using online services including webmail and social-networking sites. Servers may be located in different jurisdictions, said Clayton, and data-retention times may be short.
"The government wants to collect all of this data on everybody, just in case," said Clayton. "Suppose you use hotmail.pk, and you blow up the Houses of Parliament. The government would have to persuade the Pakistani authorities to turn over the logs, which may then turn out only to have been retained for three days."
However, Clayton believes that the cost of harvesting this information, which would involve all UK internet infrastructure providers and ISPs having 'black boxes' to monitor data, would be prohibitively expensive. Clayton said that taxpayers' money would be better spent on the police, who could target investigations to those they suspect of criminal activity, rather than on performing blanket surveillance of everybody.
"To deploy deep packet inspection equipment isn't cheap the word 'billion' is appropriate," said Clayton. "It took the Home Office the best part of a year to find 3m for the Police e-Crime Unit. That's what is wrong with this picture."
Web inventor Sir Tim Berners-Lee also opposes the use of deep packet inspection to inspect people's data. Berners-Lee told ZDNet UK last week that the internet should not be "snooped" upon.
"If [third parties] are using the data for political ends or commercial interest, there we have to draw the line," Berners-Lee said. "There's a gap between running a successful internet service and looking inside data packets."
