Stanford researchers discover ‘alarming’ method for phone tracking, fingerprinting through sensor
SF Gate ^ | James Temple

One afternoon late last month, security researcher Hristo Bojinov placed his Galaxy Nexus phone face up on the table in a cramped Palo Alto conference room. Then he flipped it over and waited another beat.

And that was it. In a matter of seconds, the device had given up its “fingerprints.”

It’s a novel approach that raises a new set of privacy concerns: Users couldn’t delete the ID like browser cookies, couldn’t mask it by adjusting app privacy preferences — and wouldn’t even know their device had been tagged.

Security researchers at Stanford have discovered methods of “fingerprinting” mobile devices by measuring tiny errors in the sensors, including the accelerometer and microphone. The degree of error is unique to each phone because, despite streamlined industrial processes, no two devices roll off the assembly line functioning in the exact same way.

The variations can be used to create IDs for phones that advertisers, and perhaps law enforcement, could exploit to track the devices.

Anyone want to bet that your Smart Phone finger prints will never enter the National Fingerprint database. Am I being paranoid?? Seriously.

Live by the cell phone, die by the cell phone.

A device we all did perfectly well without throughout the history of human-kind.

Yes, please, please, PLEASE tell me your stories about how it saved your life, or your kid’s life, or some such. PLEASE! Such great stories, heart-warming, app-download-inspiring, but . . . life expectancy seems to have been largely unchanged since these things flooded the culture. Or what’s now left of our culture.

Call me on my cell if you disagree. Or text, or tweet, or visit me on FaceBook (and “like” me when you do!)

Not at all surprising.

Even the accelerometers that go into aviation-grade inertial nav systems have errors; much effort goes into compensating for those errors via Kalman filters and the like.

I wonder if they are simply reading the compensations files that were created during factory calibration?

That would actually be more reliable if you’re trying to monitor a particular device; actual acceleration-due-to-gravity as measured by any particular sensor varies with location and elevation.

There’s a reason some of us still use “dumb” phones—and I’m not sure they’re safe euther.

In 2002 and prior they called people 'fringe' and 'nuts' for citing stuff like what was happening in England.

Poster from here below

In this age of smart phones, identity theft, online banking and now all the NSA crap people should start focusing on making their lives more private to protect themselves and their families. Cloud computing? Not me. Online banking? Fugetaboutit. Does your Credit Card have RFID? My .02.

I can’t recall an invention that changed human behavior on a planet wide scale in such a short time period.

Yeah, I know. 10 years ago, cellphones only were for calling people. 20 years ago, they looked like Star Trek communicators and those without used pagers (remember those?). 30 years ago, they were the size of lunchboxes or if lucky, a brick. There are days I long for the days prior to cellphones, heck, I remember when CB radio was big and fun. Between this and the internet, I keep thinking ti is an allegory to the Biblical story of The Tower of Babel, if a few key parts stop working, the whole mess will come down and we are back to landlines (if lucky) or radio in the shortwave/VHF/UHF bands ala CB and ham radio and others.

BTW, here is a pic about wiretapping from 1963:

If I could kill one invention, cellphones would be it.
