It's Trivially Easy To Identify You Based On Records of Your Calls and Texts (dailydot.com)

Reader erier2003 shares an article on Daily Dot: Contrary to the claims of America's top spies, the details of your phone calls and text messages -- including when they took place and whom they involved -- are no less revealing than the actual contents of those communications. In a study published online Monday in the journal Proceedings of the National Academy of Sciences, Stanford University researchers demonstrated how they used publicly available sources -- like Google searches and the paid background-check service Intelius -- to identify "the overwhelming majority" of their 823 volunteers based only on their anonymized call and SMS metadata. The results cast doubt on claims by senior intelligence officials that telephone and Internet "metadata" -- information about communications, but not the content of those communications -- should be subjected to a lower privacy threshold because it is less sensitive. Contrary to those claims, the researchers wrote, "telephone metadata is densely interconnected, susceptible to reidentification, and enables highly sensitive inferences."IEEE has more details.

    With thousands of agents with warrantless access, it will be trivial for a plant to track who a political opponent calls to flesh out their supporter network.

    This will allow for mysterious IRS audits, in the worst case, or just rhetorical games to discredit people.

    This is the reason government spy powers on citizens are supposed to be limited to warrants -- the goal was stopping those in power from harassing opponents.

    The King of England would have traced phone call networks. And so the founding fathers would have banned it sans warrant.

    The modern "metadata" concept is a complete unconstitutional fraud designed to pretend to honor this by asserting only the content of the call is private. Yet the connecting the dots is precisely and arguably more important.

    Just get a damned warrant so it is all tracked and reviewed by elected officials.

      Umm...as the great Asimov explained via Harry Seldon & Psychohistory its NOT about 'single events' its about the 'totality of the events'...

      Sure, if you killed 1 person & had to move the body, the metadata about your phone call to a friend may be of little use. BUT if you're a serial killer, the metadata on your movements, purchasing habits, calls made etc. etc. may be usable to 'sus out' that you're in fact a serial killer...something that someone might claim is a 'good end result justifying the means'...but I only use this example as you referenced moving a body (I presumed you're not a mortician or someone else legally allowed to move bodies).

      BUT, the same type of data can be used to generate information about your otherwise legal activities that someone might try to use to discredit you or even via other circumstantial evidence jail you for a crime you didn't commit but hey they 'caught someone'...and clearly the government would NEVER charge someone with a crime they didn't commit...at a minimum 'you must have done something wrong to justify government invasion in to your private life'...but of course that is NOT the way it supposed to work. First they need to generate sufficient evidence to demonstrate that you have some connection to a crime beyond just 'you happen to hang out with people connected to other bad people under suspicion' (e.g. you hang out at a mosque where 'OMG, terrorists hang out!')...

      The point being is that 'metadata' is data about your private life, not really any less private then the contents of your conversations, e-mails, texts etc. and as such require the same level of protections...if the government (not business btw as the constitution is about limits on government power) wants to gather data about you or even use data about you that you had to give them for some other purpose (by law)...for example your tax return; than they need to get a fuckin' warrant!

      I tended to agree until I pondered this more and read about Paul Revere and meta-data. Consider many/most conversations if recorded may be "harmless" (uninteresting or not containing anything relevant to an "investigation") but the connections made themselves could reveal quite a bit of interesting things. It is possible even more in fact than what was captured and realized in a recording/transcript if codes were used (as they were even in American revolutionary days), for one quick example. But it is quite clear to me that the potential for abuse is far bigger than *I*, much less then general public could have thought. And one thing I've learned about potential, active people (read: in power) hate to let it go to waste... and it's to easy to take something that is easily over the majority of people's heads (even if it's merely because they're unfamiliar) and rush to capitalize on it's "merits" without considering the consequences.

    The founding fathers experienced what life was like when general warrants was law, and purposely limited the scope of how the government could collect information on citizens as well as provide oversight and justification when they do. History has shown us what happens when supposedly democratic governments are left unchecked in their abuse of surveillance powers and secret police: https://en.wikipedia.org/wiki/Night_of_the_Long_Knives

    Or perhaps something a little more closer to home?
    https://en.wikipedia.org/wiki/J._Edgar_Hoover

    So from that context, compare to where we are today with mass surveillance, secret courts that judge secret law, and shadowy government agencies that can brazenly lie and are held unaccountable to even congress with their activities. (http://www.theguardian.com/world/2013/jun/28/senators-james-clapper-nsa-data-collection)

    Consider for a moment what happened to Thomas Drake and Joseph Nacchio, both men who stood in the way of expanding government surveillance. Consider them and all the other people who suddenly found themselves being punished, both directly and indirectly, for being whistleblowers and finding their lives and reputations in ruins or ending up in jail.

    Does this begin to paint a picture for you, about why even phone metadata should be guarded? What if, without even needing a warrant or any form of accountability, I could use this data to construct the total framework of your life: who you talk to, who your friends and family are, when you talk to them and where you are when you do, and anyone else that might make you guilty by association.

    It isn't a coincidence that banks and those that run them are untouchable and are likely to stay that way, and there has never been more money in the political system than there is now.

    It isn't a coincidence that domestic spying is ever expanding, while whistleblowers and reporters are being targeted like never before. Obama has charged people under the espionage act more times than any other president combined.

    It isn't a coincidence that the FBI building still has Hoover's name on it, even after the legacy of COINTELPRO. Only now we live in a world where everyone has a digital footprint whether we want to or not, and most of us carry wireless devices that come equipped with gps, cameras and a microphone that we have no real control over.
