Concerned after a European court ruled in favor of citizens' right to privacy, Britain's prime minister pledged Thursday to rush through emergency measures to force phone and Internet companies to store call and search records for a year.
The European Court of Justice ruled in April that a European Union directive requiring companies to store communications data for up to two years was too broad and a threat to privacy rights.
Prime Minister David Cameron said Thursday without the emergency law, governments would be less able to protect the country from pedophiles, gangsters and terrorists.
Cameron said the UK legislation will respond to the court's concerns and provide a clear legal basis for companies to retain communications metadata such as phone call records or Internet search records. This does not include the content of the communications themselves. Without such action, telecommunications providers would start deleting the information, leaving a vacuum for law enforcement agencies and intelligence services, he said.
"Sometimes, in the dangerous world in which we live, we need our security services to listen to someone's phone and read their emails to identify and disrupt a terrorist plot," Cameron told reporters. "As prime minister, I know of examples where doing this has stopped a terrorist attack."
Cameron stressed that the measures did not impose new obligations on data companies and insisted they would not authorize new intrusions on civil liberties.
"I want to be very clear that we are not introducing new powers or capabilities," he said.
Data companies have also expressed concern about the debate between privacy rights and security concerns and have called for a clearer legal framework in order to cooperate with law enforcement and intelligence agencies.
In a ground-breaking report last month, Vodafone revealed the extent to which governments seek out information from telecommunication providers. The report, which covered the 29 countries in which Vodafone operates, highlighted the thousands of requests that governments make for information.
Wiretapping phones and accessing call records for law-enforcement purposes is a decades-old practice even in the most open democracies. With backing from courts, police can also request cooperation from telecommunications companies as they pursue criminals.
But technology is transforming the arena.
The European court was concerned about the lack of restrictions on how, why and when the metadata could be used. It asked for a directive with more specificity on what type of crimes could be covered and how long the material would be retained.
The British legislation covers the collection of metadata, which make it possible for law enforcement authorities to identify subscribers and who they communicate with, as well as the time, place and frequency of communications. Such information doesn't include the content of any communications.
Cameron billed Thursday's measure as temporary, saying it will expire in 2016. The government says the stopgap measure will allow security and law enforcement authorities to keep functioning while giving Parliament time to create a more thoughtful law for a rapidly changing world.
