Android Platform Mobile Phones Also Track Your Movements

Posted on April 22, 2011


Just days after it was discovered the iPhone has secret files that track the owner’s movements and retain the information for at least a year, the Guardian features a story claiming that Android phones have the same kind of capability.

Magnus Eriksson, a Swedish programmer, has shown that Android phones – now the bestselling smartphones – do the same, though for a shorter period. According to files discovered by Eriksson, Android devices keep a record of the locations and unique IDs of the last 50 mobile masts that it has communicated with, and the last 200 Wi-Fi networks that it has “seen”. These are overwritten, oldest first, when the relevant list is full. It is not yet known whether the lists are sent to Google. That differs from Apple, where the data is stored for up to a year.

In addition, the file is not easily accessible to users: it requires some computer skills to extract the data. By contrast, the Apple file is easily extracted directly from the computer or phone.

The discovery that Android devices – which are quickly becoming the best-selling products in the smartphone space – also collect location data indicates how essential such information has become to their effective operation. “Location services”, which can help place a user on a map, are increasingly seen as important for providing enhanced services including advertising – which forms the basis of Google’s business.

Steve Jobs has not yet explained the use for this tracking devices.  No matter the reason, it remains a breach of privacy and the issue needs to be legally addressed.  Senator Al Franken has come forward demanding explanations and information about this breach.

Senator Franken has asked Jobs to explain the purpose and extent of the iPhone’s tracking. “The existence of this information – stored in an unencrypted format – raises serious privacy concerns,” Franken writes in his letter to Jobs. “Anyone who gains access to this single file could likely determine the location of a user’s home, the businesses he frequents, the doctors he visits, the schools his children attend, and the trips he has taken – over the past months or even a year.”

Franken points out that a stolen or lost iPhone or iPad could be used to map out its owner’s precise movements “for months at a time” and that it is not limited by age, meaning that it could track the movements of users who are under 13. Another security researcher, Alex Levinson, says that he discovered the file inside the iPhone last year, and that it has been used in the US by the police in a number of cases. He says that its purpose is simply to help the phone determine its location, and that he has seen no evidence that it is sent back to Apple. However documents lodged by Apple with the US Congress suggest that it does use the data if the user agrees to give the company “diagnostic information” from their iPhone or iPad.
