Eavesdropping on private calls a Serious problem: Govt

New Delhi: Mobile phone users, be they politicians, sensitive post holders or the moneyed, face a serious problem with latest technology allowing rivals and criminals to eavesdrop and record their private conversations, the Centre told the Supreme Court on Tuesday.
A PIL by one Ravindra Kumar had alleged that the government and probe agencies indiscriminately intercepted telephones without following procedure. The government denied the charge but clarified, “With the advancement of wireless networks worldwide, many eavesdropping techniques have also been developed.”
Dealing with politician Amar Singh’s allegation about illegal interception of his phone, a Bench comprising Justices G S Singhvi and A K Ganguly said, “It is more serious. If a service provider connives with a private person and starts intercepting telephones, then it is very dangerous. Anyone can go to the service provider and listen to the conversations.”
Attorney general G E Vahanvati shared the court's concern and said a service provider need not even be approached. He said technology had advanced to such an extent that one just needed to download the software from the internet and feed the mobile phone pin number in it to listen and record the conversations. “People are eavesdropping on many conversations. It is a serious problem. I am seriously concerned about it,” the AG said.
The government's affidavit said the present encryption algorithm, technically termed A5/2, used by global system mobile (GSM) service providers to transmit conversations from one phone to another, was weak in security. “A few have upgraded to A5/1, which provides higher security. Newer technologies such as 3G envisage further advanced algorithm,” it said.
