How much privacy can smartphone owners expect?

Many consumers continue to allow mobile applications that can locate them
The US Supreme Court
could soon allow police to monitor the movements of US
mobile phone users without a warrant. Now that most of us carry sophisticated tracking devices in our pockets, how much privacy do we have a right to expect?
Millions of us happily invade our own privacy every day on Twitter and Facebook, sharing personal details with the world and broadcasting our location in a way previous generations would have found bizarre.
Even those who shy away from social media and new technology in general are not immune. The most basic mobile phones are in constant contact with the nearest mast, sending information about the whereabouts of their users to phone companies, who can later hand that data over to the police, if requested.
At the other end of the spectrum, in the world of smartphones, privacy is becoming an increasingly outdated concept, argues technology writer Sam Biddle. What might once have been considered “creepy” and invasive is becoming normal.
“That line of creepiness is there, but it’s eroding quickly because, frankly, we are just getting used to it,” says Mr Biddle, a staff writer for Gizmodo.com.
“Something like (smartphone app) Foursquare, something like Find My Friends, these things all would have sounded like something from 1984. Now they are fun and free.
“So I think whatever line there once was is receding very quickly.”
He adds: “The excitement and the novelty of it blinds us to the fact that is a little weird and maybe, in terms of privacy rights, a little ominous.”
For the smartphone customer “it’s a trade-off, in terms of privacy versus service,” he says. For the mobile phone company “following you around is just part of the service”.
There are signs that governments and law enforcement agencies around the world are taking advantage of this increasingly relaxed attitude towards privacy to step up surveillance of citizens.
The case currently before the Supreme Court, US vs Jones, hinges on whether police officers should be allowed to plant GPS tracking devices on suspects’ cars without a warrant.
Nightclub owner and suspected drug smuggler Antoine Jones had such a device attached to his vehicle for 28 days so officers could follow his movements in order to build up a case against him.
His legal team argued at a Supreme Court hearing earlier this month that his Fourth Amendment rights, which are meant to protect US citizens from invasive searches, were violated.
Lawyers for the Obama administration argued that Jones did not have a “legitimate expectation of privacy” – the standard legal test in the US for the past 45 years – because his car was in a public place.
Attaching a tracking device to it was no different to tailing him, which has always been legal, the government argued.
If the Supreme Court agrees, it could open the door to mass unwarranted surveillance of suspects using GPS bugs, civil liberties campaigners have warned.
Open to abuse?
But law enforcement officers no longer have to physically plant a bug on a suspect’s car or person. In the US, they are increasingly using mobile phone tracking software.
“Police officers can sit in the comfort of their own stations and use this technology to watch not just one person, but many people, over long periods of time,” says Catherine Crump, an attorney for American Civil Liberties Union.
This is far more invasive than traditional surveillance, she argues.
“GPS tracking can actually be quite revealing about who a person is and what they value. It can show where a person goes to church, whether they are in therapy, whether they are an outpatient at a medical clinic, whether they go to a gun range.”
Without police officers being forced to go before a court to obtain a “probable cause” warrant, the technology is wide open to abuse, the ACLU argues, and it is hoping that the Supreme Court will ban all warrantless surveillance when they deliver their verdict in the Jones case.
“I don’t think you have to be a card carrying member of the ACLU to be concerned about a world in which every citizen of the United States can be tracked on the whim of a curious police officer, for any reason, or no reason at all,” says Ms Crump.
But police and prosecutors tend to take a different view.
“If it is a legitimate law enforcement need and there is no time to get a warrant there should be occasions when you can use a tracking device,” says Ed Marsico, district attorney for Dauphin County, in Pennsylvania.
