How Law Enforcement Can Use Google Timeline To Track Your Every Move

THE RECENT EXPANSION of Google’s Timeline feature can provide investigators unprecedented access to users’ location history data, allowing them in many cases to track a person’s every move over the course of years, according to a report recently circulated to law enforcement.

“The personal privacy implications are pretty clear but so are the law enforcement applications,” according to the document, titled “Google Timelines: Location Investigations Involving Android Devices,” which outlines the kind of information investigators can now obtain.

The Timeline allows users to look back at their daily movements on a map; that same information is also potentially of interest to law enforcement. “It is now possible to submit a legal demand to Google for location history greater than six months old,” the report says. “This could revitalize cold cases and potentially help solve active investigations.”

The report was written by a law enforcement trainer, Aaron Edens, and provides detailed guidance on the wealth of historic location information available through Google Timeline and how to request it. A copy of of the document was obtained by The Intercept.

The expansion of Google’s Timeline feature, launched in July 2015, allows investigators to request detailed information about where someone has been – down to the longitude and latitude – over the course of years. Previously, law enforcement could only yield recent location information.

The 15-page document includes what information its author, an expert in mobile phone investigations, found being stored in his own Timeline: historic location data – extremely specific data – dating back to 2009, the first year he owned a phone with an Android operating system. Those six years of data, he writes, show the kind of information that law enforcement investigators can now obtain from Google.

The document also notes that users can edit or delete specific locations in their history, or an entire day, stressing the importance of preservation letters for criminal investigators involving Android phones. “Unfortunately, Google has made it very easy to delete location history from a specific date,” he wrote.

There is no indication data is recoverable from Google once it has been deleted by the user, the report says.

Location data is only stored in users’ Google accounts if they enable the feature. Individual Android users can turn it off, but users often don’t.

The ability of law enforcement to obtain data stored with privacy companies is similar – whether it’s in Dropbox or iCloud. What’s different about Google Timeline, however, is that it potentially allows law enforcement to access a treasure trove of data about someone’s individual movement over the course of years.

The report also advises investigators to remember there is a significant amount of other information retained by Google.

“Consider including Gmail, photos and videos, search history, contacts, applications, other connected devices, Google Voice and Google Wallet, if they are relevant to the investigation,” the report suggests. Investigators are also advised to include a non-disclosure order with their search warrants for Google data, which prevents the company from notifying the account holder that their data is being provided to law enforcement.

It’s impossible to know how many of these requests for historic Timeline location information have been made by law enforcement, since Google does not specify what types of requests it gets from law enforcement. Google’s transparency report provides information on the number of requests received from law enforcement, and the most recent requests go up to the end of 2014 and do not cover the time period after the expanded Timeline was launched. (In the first half of 2014, Google received 12,539 criminal legal requests in the U.S. and in the second half it received 9,981.)

The major barrier law enforcement faces is that Google does not provide any additional advice or help on deciphering data, once it is turned over under subpoena or warrant. “Based on conversations with other law enforcement investigators and prosecutors, they have resisted attempts to bring them into court to discuss the issue,” Edens wrote.

“Google does not provide expert witness testimony,” Edens said in response to The Intercept’s questions, noting that this is a similar practice to that of other companies, like Facebook. His report, he added, was written to help law enforcement in the absence of assistance from Google.

“Google has always been wary of any perceived cooperation with law enforcement, even before [Edward] Snowden,” he said.

“We respond to valid legal requests, and have a long track record of advocating on behalf of our users,” a Google spokesperson told The Intercept.

In an email, the Google spokesperson notes that the company requires a warrant to obtain detailed user data such as that available in Timeline. “A subpoena,” the  spokesperson writes, “is not and has never been sufficient to get it.” The article has been updated to reflect this.

FWIW, you can get to your "Timeline" here: link. It is rather revealing. You can delete your history from that webpage if desired.

You have to turn off the recording on your device:

1. Go to your settings and select "location":
   
   
   
   
2. Then select Google Location History:
   
   
   
   
3. Then you should make sure that the checkbox on this screen is "unchecked":
   
   
   
   Additionally, you can delete device history for all devices associated with this email by clicking on the "delete location history" button on that page.

Now I have no illusion that this prevents data from being collected in the first place (if nothing else, your cell provider will have data on which cell tower your phone is hitting). But at least you've made your wishes known.

Step 4. Have your cell phones in a company name rather than an individual account.

If the device does not have a “Off” switch I won’t have it.

“Okay, he’s on the couch watching television.”

“He’s in the kitchen.”

“He’s back on the couch.”

“He’s moved to his computer.”

“He’s in the bathroom taking a le*k.”

“He’s... yes, he’s back on the couch!”

“He’s left the premises... he’s... he’s getting the mail from the mail box.”

“Now he’s back on the couch.”

“There is no indication data is recoverable from Google once it has been deleted by the user, the report says.”

That statement is probably just there for public consumption
and most likely not true. I doubt google actually deletes the
data from it’s servers. You might get it off of your phone
but that’s probably about it.

Very helpful, thanks.

It defaults to “on” — sneaky SOBs

Do not fear Law Enforcement, fear the divorce lawyer!

They can get all of that information with a thermal sensing camera outside your home while they are sitting in a van.

[a fool in paradise]

And they claim that isn’t an invasion of privacy.

my phone sits on the counter top all week - I check messages when I get home

if you want me, email me - theres a paper trail

I lived without this crap when we all had rotary phones - I live without it now...kids are grown and independent...just like I raised them....and I don't want to talk to anyone except mrs rev when I get home

This horsecrap of everyone staring at their palms is too much and its become valium for the psyche and ego...particularly for the selfie narcissist crowd

Now, sit down, grab some Gin and lets shoot the breeze over a nice steak and salad

That’s why I only have a “dumb” phone—a little cheapie flip phone that only is used to make and receive actual phone calls.

I don’t need to be all that connected 24/7.

[Labyrinthos]

Just turn off the GPS/location tracking, which is set to “on” by default. This is not complicated. If you are smart enough to log on to FR, then you ought to be able to turn off the location tracker on your smart phone.

[peyton randolph]

If the device does not have a "Off" switch I won't have it.

Even turned off cell phones can be tracked.

When I got the new vehicle it was import to me that the vehicle did NOT have a built in GPS signal

Not yet. Will be mandatory soon. As of now, the black boxes installed in vehicles are bad enough.

“That’s why I only have a “dumb” phone—a little cheapie flip phone that only is used to make and receive actual phone calls.”

“I don’t need to be all that connected 24/7.”

That’s me, I also know how to read a road map, if I ever buy another vehicle I DO NOT want built in GPS. Of course that won’t matter much longer they’ll no doubt have satellite sensors that can track us all by the distinctive smell of our farts. I am beginning to think that we would be better off without most of this danged technology stuff.

[Disambiguator]

Now, sit down, grab some Gin and lets shoot the breeze over a nice steak and salad.

Hey, I like you. That sounds like my kind of evening. Make mine a single-malt, though.

[FourPeas]

I am beginning think that we would be better off without most of this danged technology stuff.

It certainly comes with a whole host of drawbacks not the least of which is loss of privacy.

[RipSawyer]

Yes, I think we have reached the point at which real privacy is impossible and that means real freedom is impossible. Those who say that if you are not doing anything wrong you don’t have anything to worry about are simply thinking like small children, you have to realize that you are NOT the one deciding whether what you are doing is right or wrong. That is being decided by lunatics like Nancy Pelosi and others who have taken over government and if some get their way it will be decided by Hillary Clinton. Nuff sed.

Good thing I have no use for logging onto facefarque 24/7 with a smartphone, or need one for anything else that a simple cell phone will not do.

Thought I read cell phone makers at one time used cell tower triangulation for rough position fix, then started embedding GPS receivers. Be nice to know when the switchover started.
