Smartphone Apps May Share Info with Advertisers

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?

啟用GPS，智能手機(jī)里很多應(yīng)用程序就能助你一臂之力。不過(guò)啟用之后，那些應(yīng)用程序到底干了些什么，你清楚嗎？

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.

計(jì)算機(jī)科學(xué)家倒是很想弄清楚。為此，他們對(duì)安卓手機(jī)平臺(tái)進(jìn)行了改造以標(biāo)記應(yīng)用程序從手機(jī)中發(fā)出的所有數(shù)據(jù)。他們又隨機(jī)選擇了其中最流行的30個(gè)應(yīng)用程序（這些程序都需要接入網(wǎng)絡(luò)，啟用GPS、照相機(jī)或是話(huà)筒），然后一邊使用這些應(yīng)用程序，一邊追蹤各個(gè)程序發(fā)出的數(shù)據(jù)。

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.

追蹤結(jié)果：15個(gè)，也就是一半的應(yīng)用程序?qū)⑹謾C(jī)的方位發(fā)送給了第三方廣告商。2個(gè)程序雖然開(kāi)啟了，但并沒(méi)有發(fā)送數(shù)據(jù)。三分之一的程序發(fā)送了手機(jī)特有ID，有時(shí)甚至手機(jī)號(hào)碼和SIM卡序列號(hào)也會(huì)被發(fā)出去。這些發(fā)現(xiàn)將在即將舉行的UNIX用戶(hù)協(xié)會(huì)討論會(huì)上予以發(fā)表。

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.

研究人員不會(huì)透露哪些應(yīng)用程序最易泄露用戶(hù)信息，但你的手機(jī)里很可能安裝了其中的一部分。假如某個(gè)應(yīng)用程序要求獲取你的方位信息，那你大可以選擇無(wú)視掉它~
