A lot of smartphone apps can help you out if you let them access your phone's GPS. But even if you give permission, do you know everything they're doing with that information?
Some computer scientists wanted to find out. So they modified the Android mobile phone platform to tag all data apps sent from the phone. Then they randomly selected 30 of the most popular Android apps, choosing only ones that require access to the Internet and access to the phone's GPS, camera or microphone. And they played with them, all while tracking the data each app sent out.
Turns out 15—half the apps—sent the phone's location to third-party advertisers. Two apps did present user agreements—but they said nothing about sending that data. And a third of the apps revealed the phone's unique ID, sometimes along with the phone number and SIM card serial number. The findings will be presented at an upcoming USENIX Symposium.

The researchers won't say which apps committed the worst offenses. But there’s a good chance you could have some of the apps on your smartphone. And if one of them asks for your location, you can opt to have it mind its own business instead of yours.
Cease Your Hunting for Privacy In recent years,many newspapers and magazines feature stories about the private life of film stars,pop singers or even some famous political figures.Reporters disguise their identities,infiltrate the subjects＇ business and family,or even bug and wiretap themto get the firsthand news by whatever means nec Their single motive is to raise the publication and hence a huge profit by means of satisfying the readers＇ curiosity in the name of "people＇s right to know."
However,at the same time,the bad effects they bring to the famous people,the public readers and even the whole society are countless.Standing in the shoes of those exposed people,you＇ll find out that their legal right of privacy is deprived by such press attention.What awaits them is severe injury.To escape the hunters,Catherine Zeta Jones,when conceiving her second child,had to pay millions of dollars in avoiding cameras of those who illegally broke in,the result of which is that the other day when she gotup,the reports titled "Catherine spentsix million dollars..." dramatically appeared on the front page of all news What a ridicule!The reporters＇ ability to hunt privacy turns out endless nightmares of the famous who are under the pressure of public media and suddenly become sensitively cautious or easily raged,being afraid of losing their reputation and receiving accidental insults.Compared with Princess Diana who was famous and popular at the cost of her young,beautiful life,should Catherine say "Thank you?" Thanks to whom?
To theprivacy hunters,the public media,the social phenomena caused by newspapers and magazincs; feature stories,or maybe all of us who are misled by such media?With our curiosity to others＇ privacy wrongly aroused,our taste of culture and life is on the decrease,our passion transferred from our own life and career.What＇s worse,we eventually become the accomplices who join in the vicious cycles of the whole enterprise.At least two main victims suffer in the hunting.And the third is no doubt the whole society who bears all kinds of losses,from the suicide of the young talented actress to the give up of new stars in scientific field who intended to devote their brilliance to the whole world.Even the prime minister of Britain is recently bothered by the "scandal" of his wife.As a result,he fails to deal efficiently with the national events.To avoid such tragedies,hunters,please cease your illegal photography,and your dangerous hunting for privacy.
