    Is your private phone number on
    Facebook? Probably. And so are
    your friends' Uploads from iPhones using the
    Facebook app will push all your
    contacts onto Facebook's servers
    - where they'll be matched
    against any and everyone.
    Worried at all? Update: Or how about a random Facebooker's
    number? book's iPhone app does ask
    you to press a button before
    using it. And agree to something.
    But what, precisely? If you have a friend on Facebook
    who has used the iPhone app
    version to access the site, then
    it's very possible that your
    private phone numbers - and
    those of lots of your and their friends - are on the site. The reason: Facebook's "Contact
    Sync" feature, which
    synchronises your friends'
    Facebook profile pictures with
    the contacts in your phone. Except that it doesn't do that on your phone. Oh no. Because that would be wrong, to pull the photos down from Facebook and put them on your phone. That would breach Facebook's terms of service. Update: A more recent version of the app shows that it
    does download "your friends'
    profile photos and other info
    from Facebook" to add to your
    iPhone address book. Instead, what What Facebook's app does it that it imports all the names and phone numbers you
    have on your (smart)phone,
    uploads them to Facebook's
    Phonebook app (got a Facebook
    account? Here's your Phonebook) . (Update: Rhodri Marsden says that you'll now get a big
    warning sign saying that the
    numbers are imported into
    Facebook. That's above.) Pause for a moment and go and look at it. Did you know those numbers? Did you collect them?
    Despite the reassuring phrase
    there - "Facebook Phonebook
    displays contacts you have
    imported from your phone, as
    well as your Facebook friends" - it's absolutely not true. I know
    because there are numbers there
    which I don't have. OK, perhaps
    the people who own them added
    them; but that's not clear either.
    So how did they get there? Because it only takes one person
    to upload another person's
    number, and the implication is
    that it's going to be shared
    around everywhere. Update: that's the implication of "all contacts from your device...
    will be sent to Facebook and be
    subject to Facebook's Privacy
    Policy". Note, not just your
    friends - but everyone on your
    device. The implications are huge, and
    extremely worrying. All it takes
    is for someone's Facebook
    account to be hacked (perhaps
    via their phone being stolen) and
    lots of personal details are revealed. Or, as Craig noted in the comments, you get your phonebook record of "Steve
    Car" (which was for his garage
    mechanic) somehow linked to
    someone called "Steve Carlton" -
    who he doesn't know. Update: Facebook says, in a statement: "Facebook never
    shares personally identifiable
    information with third parties –
    advertisers are only given
    anonymised and aggregated
    data." It also adds: "Facebook is a free service and something that
    many people find adds value to
    their day-to-day lives. As with
    any service, users do need to
    invest some time in order to use
    it properly and we encourage people to use their privacy
    settings to do this and to access
    the Help Centre for support." Kurt von Moos, who first wrote about this earlier this year (since when Facebook has revised its
    privacy statement, but not
    altered what goes on in this
    way) says that there are a
    number of reasons to be
    concerned. As he puts it: "1) Facebook doesn't warn
    users that they are
    uploading their phone's
    adress book to Facebook. In
    fact, because Facebook
    doesn't sync contact numbers or email addresses
    TO your phone, most users
    wrongly assume that
    Facebook Contact Sync only
    syncs user pictures. In
    reality though, they are pumping your address book,
    without your
    consent." [Since then the
    Facebook app has clearly
    been updated with a
    warning.] Facebook says you can remove your mobile contacts, but it's not clear that that will remove your
    mobile if someone else uploads
    it. von Moos continues: "2) Phone numbers are
    private and valuable. Most
    people who have entrusted
    you with their phone
    numbers assume you will
    keep them private and safe. If you were to ask your
    friends, family or co-workers
    if they are ok with you
    uploading their private
    phone numbers to be cross-
    referenced with other Facebook users, how many
    of them do you think would
    be ok with it?" He also points to even more
    egregious problems: (a) can you
    be sure how Facebook, or its
    advertisers or partners or
    whatever it becomes down the
    line, will use that data? (b) why is it that Facebook takes all your
    mobile numbers, rather than
    matching names of contacts with
    names of friends? (c) sometimes,
    it gets the matches wrong - and
    incorrect (or faked) data that people have given to Facebook
    as their "contact" details (such as
    hotels or businesses) gets linked
    as being a "friend", or the lack of
    an international dialling prefix
    messes up the match, and means again that someone who you
    don't know is identified as a
    "friend" or contact. von Moos concludes: "There are
    some contacts and phone
    numbers who's privacy I simply
    refuse to risk on the Web.
    Facebook has taken and
    continues to take liberties on behalf of their users. Their
    perception of privacy and their
    users perception of privacy is
    often very different. I don't think
    this is maliciousness on
    Facebook's part, but it does show me that Facebook is painfully out
    of touch with the needs and
    beliefs of their CORE users, who
    are still wary of the openness
    that a Web 2.0 lifestyle entails...., SOMA ZAIDI KWENYE HIYO LINK JUU HAPO!
