You Don’t Know Me

Or, if you work at cer­tain com­pa­nies, you do. Or could.

I had some inter­est­ing con­ver­sa­tions about pri­vacy at ALA’s Mid­win­ter Meet­ing, which got me think­ing about which com­pa­nies prob­a­bly know the most about me.

I’ve thought about my own “walled gar­den” a lot and worked through what I’ll share pub­licly, pri­vately, and pre­tend pri­vately. Most things I share pub­licly, and you can see a list of many of the sites I use on my Friend­Feed account. It’s not dif­fi­cult to piece together infor­ma­tion about me by track­ing these sites, but over­all I’m more care­ful with spe­cific things like loca­tion information.

The rou­tine I’ve worked out is that Face­book is my only truly pri­vate post­ing area, although I do occa­sion­ally post some pic­tures for “friends and fam­ily only” on Flickr. Since I still don’t trust Face­book to not re-publish or claim own­er­ship of “pri­vate” con­tent (like pic­tures and videos), I don’t post any­thing orig­i­nal there except sta­tus updates and com­ments on friends’ updates. Even then, I don’t kid myself that those things are truly pri­vate (they’re the “pre­tend pri­vately” I men­tioned above). That’s why I’ve become a lot more selec­tive about who I’ll friend there, and why I post some Foursquare loca­tion updates there (rather than on Twitter).

So if you can find out so much infor­ma­tion about me pub­licly, which com­pa­nies know the most about me? It’s been a very thought-provoking exer­cise to come up with the fol­low­ing list. I tried to rank the com­pa­nies in order of how much daily infor­ma­tion I think they’re accu­mu­lat­ing about me, but it’s tough to decide if “what I’m eat­ing” equals “what I’m watching.”

  • Cell carrier/cellphone maker — they know my loca­tion at any given time, plus all of the data that goes through my phone (and I don’t have a land­line, so every­thing goes through my cell)
  • Cable com­pany = they know what I watch on TV and what I surf on the net
  • Bank = they know most of the places where I spend my money
  • Credit cards = they know a lot of places I spend my money
  • LISHost — hosts my web­site and email, which would include a lot of receipts for online purchases
  • Google = knows most of the things I search for and many things I read (via <http://reader.google.com/”>Google Reader); even though I don’t use Gmail, any email I send to Gmail users is in their archives
  • Ama­zon = knows about a lot of things I pur­chase and read (includ­ing via my Kindle)
  • Face­book = knows a lot about what I say about myself via sta­tus updates and who my friends are
  • Friend­Feed (now owned by Face­book) = aggre­gates a lot about what I say about myself pub­licly online, plus which con­ver­sa­tions and peo­ple I watch on the site
  • Net­flix = knows a lot about what I watch
  • Foursquare = knows some about where I am/go
  • Flickr = knows a lot about where I am/go, who my friends/contacts are, and what inter­ests me
  • Twit­ter = knows my net­work and who I inter­act with the most
  • Health care provider = I’m lucky that I’ve been rel­a­tively healthy, but my provider(s) know about any problems
  • Deli­cious = knows a lot about sites I’ve vis­ited and want to remember
  • Dopplr = knows my trips and some of my friends
  • Ever­note = knows about some things I want to remem­ber, although I haven’t put much per­sonal infor­ma­tion there yet
  • Illi­nois Depart­ment of Trans­porta­tion (IDOT) = I don’t drive nearly as much as I used to any­more, but IDOT knows when I go on tollroads

Obvi­ously I’m okay with what I share pub­licly, and in many respects, there have been enor­mous ben­e­fits to doing that, but I have very lit­tle con­trol over what these com­pa­nies do with the infor­ma­tion they’re col­lect­ing about me, and I don’t trust any of them. I think the only com­pany I do trust is LISHost, which hosts my web­site and email (thanks, Blake!). How much do I really care that Face­book keeps my sta­tus updates for­ever, whereas my email provider keeps my more pri­vate mes­sages? And how much do I worry that my pri­vate email still goes through my cable provider’s net­work to get to LISHost?

I’m try­ing to rec­og­nize which com­pa­nies are col­lect­ing ambi­ent infor­ma­tion about me, with­out me proac­tively post­ing any­thing. I’m sure I’m miss­ing some, though. If you’ve thought through this your­self, what’s not on my list?

  1. I was just think­ing about this today as I got on the sub­way. I live in DC, and the fare cards are “smart cards” that you tap every time you go in / out of the sta­tion. So WMATA knows every­where I go and can track my pat­terns. And the pat­terns of every­one in the city. That skeeves me out.

  2. Gro­cery affin­ity cards? Or any affin­ity card, for that mat­ter. Pets­mart prob­a­bly knows my dog is now “senior”, though you’d never know from her romp in the snow this morning.

  3. I was also think­ing about this the other day — if you have a goodreads.com account there’s what you’ve been read­ing, a last.fm account there’s what you’ve been lis­ten­ing to, and live­jour­nal accounts have a huge list of inter­ests for each per­son. I haven’t really real­ized until lately how much infor­ma­tion I’ve been putting out there and it can be scary if you’re not aware of it.

  4. This is very true. Also con­sider your local util­ity providers, such as elec­tric­ity and water. They know essen­tially when you’re home–the peak times of use at your home.

    What gets me are the stores that ask for your phone num­ber as you pur­chas­ing goods. They track indi­vid­u­als through phone numbers–unique iden­ti­fiers. Some stores have backed away from ask­ing for per­sonal phone num­bers and use zip codes instead. These stores don’t want to be held legal liable in case their sys­tem is hacked. Often times I say that I don’t pro­vide my phone num­ber, which earns me either a response of “that’s okay” or a dirty look and some attitude.

  5. Meaghan, I won­dered about CTA cards here in Chicago, but I don’t think they’re really tracked. At least, not yet. Def­i­nitely skeevy.

    Karen, I haven’t used gro­cery affin­ity cards for a few years, although I’ll prob­a­bly start again soon. I always just tell them I for­got my card, so they enter the store one, but I think they’re start­ing to catch on.

    Leah, that’s exactly the kind of stuff I’ve been think­ing about more and more lately.

    John, I’ve run into this issue, too. I always thought the zip code was for GIS/demographic types of data, and some­times I’ll give the one for the town over from me. One of the few Google ser­vices I’ve whole­heart­edly embraced is Google Voice because it essen­tially gives me a throw­away phone num­ber that I can use in exactly these kinds of sit­u­a­tions. I use it for all of my shopping/ordering trans­ac­tions now, because I don’t care if Google knows about the solic­i­ta­tions these com­pa­nies are call­ing me with. I highly rec­om­mend this approach (hmmm… another blog post — how do we game these systems?).

    Thanks for the great com­ments, everyone!

  6. Our Inter­net providers know every site we visit, every key­stroke we enter, every credit card num­ber, every pur­chase, every bill we pay online, all of our email accounts, blogs, rss feeds, etc. They are the ulti­mate big brother. Our pass­ports now have an RFID chip in them to track us. I wrote a check to K-Mart and the clerk lit­er­ally took my dri­vers license out of my hand and entered my birth­date into the cash reg­is­ter. Nin­tendo Corp. or Sony, or whichever game plat­form you pre­fer knows what games we play on our WIIs and playsta­tions, when we are play­ing them, and where. And, of course, there is the school alumni asso­ci­a­tion, which makes the CIA and FBI look fee­ble when it comes to track­ing me wher­ever I am at fund-raising time.

  8. The first per­son I ever knew who “sounded the alarm” on our cam­pus about cor­po­rate takeovers and con­se­quent loss of both pri­vacy and many streams of information–was our librarian!
