What you need to know about face surveillance

  • 0:01 - 0:03
    How many of you
    have ever heard someone say
  • 0:03 - 0:04
    privacy is dead?
  • 0:04 - 0:05
    Raise your hand.
  • 0:06 - 0:08
    How many of you have heard someone say
  • 0:08 - 0:12
    they don't care about their privacy
    because they don't have anything to hide?
  • 0:13 - 0:14
    Go on.
  • 0:14 - 0:15
    (Laughter)
  • 0:16 - 0:20
    Now, how many of you
    use any kind of encryption software?
  • 0:20 - 0:21
    Raise your hand.
  • 0:21 - 0:25
    Or a password
    to protect an online account?
  • 0:26 - 0:29
    Or curtains or blinds
    on your windows at home?
  • 0:29 - 0:31
    (Laughter)
  • 0:31 - 0:33
    OK, so that's everyone, I think.
  • 0:33 - 0:34
    (Laughter)
  • 0:35 - 0:37
    So why do you do these things?
  • 0:37 - 0:38
    My guess is,
  • 0:38 - 0:41
    it's because you care about your privacy.
  • 0:41 - 0:44
    The idea that privacy is dead is a myth.
  • 0:44 - 0:47
    The idea that people
    don't care about their privacy
  • 0:47 - 0:48
    because "they have nothing to hide"
  • 0:48 - 0:50
    or they've done nothing wrong
  • 0:50 - 0:51
    is also a myth.
  • 0:52 - 0:56
    I'm guessing that you would not want
    to publicly share on the internet,
  • 0:57 - 0:58
    for the world to see,
  • 0:58 - 1:00
    all of your medical records.
  • 1:00 - 1:03
    Or your search histories
    from your phone or your computer.
  • 1:04 - 1:05
    And I bet
  • 1:06 - 1:08
    that if the government
    wanted to put a chip in your brain
  • 1:08 - 1:13
    to transmit every one of your thoughts
    to a centralized government computer,
  • 1:13 - 1:14
    you would balk at that.
  • 1:14 - 1:17
    (Laughter)
  • 1:17 - 1:19
    That's because you care
    about your privacy,
  • 1:19 - 1:20
    like every human being.
  • 1:21 - 1:24
    So, our world has changed fast.
  • 1:24 - 1:28
    And today, there is understandably
    a lot of confusion
  • 1:28 - 1:31
    about what privacy is and why it matters.
  • 1:32 - 1:34
    Privacy is not secrecy.
  • 1:34 - 1:36
    It's control.
  • 1:37 - 1:41
    I share information with my doctor
    about my body and my health,
  • 1:41 - 1:43
    expecting that she is not
    going to turn around
  • 1:43 - 1:46
    and share that information
    with my parents,
  • 1:46 - 1:49
    or my boss or my kids.
  • 1:50 - 1:52
    That information is private, not secret.
  • 1:53 - 1:56
    I'm in control over how
    that information is shared.
  • 1:58 - 2:01
    You've probably heard people say
    that there's a fundamental tension
  • 2:01 - 2:03
    between privacy on the one hand
  • 2:03 - 2:05
    and safety on the other.
  • 2:06 - 2:08
    But the technologies
    that advance our privacy
  • 2:09 - 2:10
    also advance our safety.
  • 2:10 - 2:13
    Think about fences, door locks,
  • 2:13 - 2:15
    curtains on our windows, passwords,
  • 2:15 - 2:17
    encryption software.
  • 2:18 - 2:19
    All of these technologies
  • 2:19 - 2:23
    simultaneously protect
    our privacy and our safety.
  • 2:25 - 2:28
    Dragnet surveillance,
    on the other hand, protects neither.
  • 2:29 - 2:31
    In recent years,
  • 2:31 - 2:34
    the federal government
    tasked a group of experts
  • 2:34 - 2:37
    called The Privacy and Civil Liberties
    Oversight Board
  • 2:37 - 2:40
    with examining post-9/11
    government surveillance programs,
  • 2:40 - 2:42
    dragnet surveillance programs.
  • 2:42 - 2:45
    Those experts could not find
    a single example
  • 2:45 - 2:49
    of that dragnet surveillance
    advancing any safety --
  • 2:49 - 2:52
    didn't identify or stop
    a single terrorist attack.
  • 2:53 - 2:56
    You know what that information
    was useful for, though?
  • 2:56 - 2:59
    Helping NSA employees
    spy on their romantic interests.
  • 2:59 - 3:01
    (Laughter)
  • 3:01 - 3:02
    (Audience: Wow.)
  • 3:03 - 3:05
    Another example is closer to home.
  • 3:05 - 3:07
    So millions of people
    across the United States and the world
  • 3:07 - 3:10
    are adopting so-called
    "smart home" devices,
  • 3:10 - 3:12
    like internet-connected
    surveillance cameras.
  • 3:13 - 3:16
    But we know that any technology
    connected to the internet
  • 3:16 - 3:17
    can be hacked.
  • 3:19 - 3:20
    And so if a hacker
  • 3:20 - 3:24
    gets into your internet-connected
    surveillance camera at home,
  • 3:24 - 3:26
    they can watch you
    and your family coming and going,
  • 3:26 - 3:29
    finding just the right time to strike.
  • 3:30 - 3:32
    You know what can't be hacked remotely?
  • 3:32 - 3:34
    Curtains.
  • 3:34 - 3:35
    (Laughter)
  • 3:35 - 3:36
    Fences.
  • 3:36 - 3:37
    Door locks.
  • 3:37 - 3:38
    (Laughter)
  • 3:38 - 3:41
    Privacy is not the enemy of safety.
  • 3:41 - 3:43
    It is its guarantor.
  • 3:44 - 3:48
    Nonetheless, we daily face
    a propaganda onslaught
  • 3:48 - 3:52
    telling us that we have to give up
    some privacy in exchange for safety
  • 3:52 - 3:54
    through surveillance programs.
  • 3:55 - 3:59
    Face surveillance is the most dangerous
    of these technologies.
  • 4:00 - 4:05
    There are two primary ways today
    governments use technologies like this.
  • 4:05 - 4:07
    One is face recognition.
  • 4:07 - 4:10
    That's to identify someone in an image.
  • 4:10 - 4:12
    The second is face surveillance,
  • 4:12 - 4:14
    which can be used in concert
  • 4:14 - 4:17
    with surveillance-camera
    networks and databases
  • 4:17 - 4:21
    to create records of all people's
    public movements,
  • 4:21 - 4:23
    habits and associations,
  • 4:23 - 4:26
    effectively creating a digital panopticon.
  • 4:27 - 4:29
    This is a panopticon.
  • 4:29 - 4:33
    It's a prison designed to allow
    a few guards in the center
  • 4:33 - 4:37
    to monitor everything happening
    in the cells around the perimeter.
  • 4:37 - 4:42
    The people in those prison cells
    can't see inside the guard tower,
  • 4:42 - 4:46
    but the guards can see
    into every inch of those cells.
  • 4:47 - 4:49
    The idea here
  • 4:49 - 4:52
    is that if the people
    in those prison cells
  • 4:52 - 4:54
    know they're being watched all the time,
  • 4:54 - 4:55
    or could be,
  • 4:55 - 4:57
    they'll behave accordingly.
  • 4:57 - 5:01
    Similarly, face surveillance
    enables a centralized authority --
  • 5:01 - 5:03
    in this case, the state --
  • 5:03 - 5:06
    to monitor the totality
    of human movement and association
  • 5:06 - 5:08
    in public space.
  • 5:08 - 5:09
    And here's what it looks like
  • 5:09 - 5:11
    in real life.
  • 5:11 - 5:14
    In this case, it's not a guard in a tower,
  • 5:14 - 5:17
    but rather a police analyst
    in a spy center.
  • 5:18 - 5:21
    The prison expands beyond its walls,
  • 5:21 - 5:23
    encompassing everyone,
  • 5:23 - 5:25
    everywhere, all the time.
  • 5:26 - 5:27
    In a free society,
  • 5:28 - 5:30
    this should terrify us all.
  • 5:32 - 5:34
    For decades now, we've watched cop shows
  • 5:34 - 5:36
    that push a narrative that says
  • 5:36 - 5:40
    technologies like face surveillance
    ultimately serve the public good.
  • 5:40 - 5:43
    But real life is not a cop drama.
  • 5:44 - 5:46
    The bad guy didn't always do it,
  • 5:46 - 5:49
    the cops definitely
    aren't always the good guys
  • 5:49 - 5:52
    and the technology doesn't always work.
  • 5:53 - 5:54
    Take the case of Steve Talley,
  • 5:55 - 5:57
    a financial analyst from Colorado.
  • 5:57 - 6:01
    In 2015, Talley was arrested,
    and he was charged with bank robbery
  • 6:01 - 6:04
    on the basis of an error
    in a facial recognition system.
  • 6:05 - 6:06
    Talley fought that case
  • 6:06 - 6:08
    and he eventually was cleared
    of those charges,
  • 6:08 - 6:11
    but while he was being
    persecuted by the state,
  • 6:11 - 6:15
    he lost his house, his job and his kids.
  • 6:16 - 6:18
    Steve Talley's case is an example
  • 6:18 - 6:20
    of what can happen
    when the technology fails.
  • 6:21 - 6:25
    But face surveillance is just as dangerous
    when it works as advertized.
  • 6:27 - 6:30
    Just consider how trivial it would be
  • 6:30 - 6:32
    for a government agency
    to put a surveillance camera
  • 6:32 - 6:36
    outside a building where people meet
    for Alcoholics Anonymous meetings.
  • 6:37 - 6:39
    They could connect that camera
  • 6:39 - 6:41
    to a face-surveillance algorithm
    and a database,
  • 6:41 - 6:43
    press a button and sit back and collect
  • 6:43 - 6:47
    a record of every person
    receiving treatment for alcoholism.
  • 6:48 - 6:51
    It would be just as easy
    for a government agency
  • 6:51 - 6:53
    to use this technology
    to automatically identify
  • 6:53 - 6:56
    every person who attended
    the Women's March
  • 6:56 - 6:58
    or a Black Lives Matter protest.
  • 6:59 - 7:03
    Even the technology industry
    is aware of the gravity of this problem.
  • 7:04 - 7:08
    Microsoft's president Brad Smith
    has called on Congress to intervene.
  • 7:09 - 7:11
    Google, for its part,
  • 7:11 - 7:14
    has publicly declined
    to ship a face surveillance product,
  • 7:14 - 7:18
    in part because of these grave
    human and civil rights concerns.
  • 7:19 - 7:20
    And that's a good thing.
  • 7:21 - 7:22
    Because ultimately,
  • 7:22 - 7:26
    protecting our open society
    is much more important
  • 7:26 - 7:27
    than corporate profit.
  • 7:29 - 7:31
    The ACLU's nationwide campaign
  • 7:31 - 7:33
    to get the government to pump the brakes
  • 7:33 - 7:36
    on the adoption
    of this dangerous technology
  • 7:36 - 7:39
    has prompted reasonable questions
    from thoughtful people.
  • 7:40 - 7:43
    What makes this technology
    in particular so dangerous?
  • 7:44 - 7:46
    Why can't we just regulate it?
  • 7:46 - 7:48
    In short, why the alarm?
  • 7:49 - 7:54
    Face surveillance is uniquely dangerous
    for two related reasons.
  • 7:54 - 7:57
    One is the nature
    of the technology itself.
  • 7:57 - 8:00
    And the second is that our system
  • 8:00 - 8:04
    fundamentally lacks the oversight
    and accountability mechanisms
  • 8:04 - 8:05
    that would be necessary
  • 8:05 - 8:09
    to ensure it would not be abused
    in the government's hands.
  • 8:11 - 8:15
    First, face surveillance enables
    a totalizing form of surveillance
  • 8:15 - 8:17
    never before possible.
  • 8:18 - 8:22
    Every single person's every visit
    to a friend's house,
  • 8:22 - 8:24
    a government office,
  • 8:24 - 8:26
    a house of worship,
  • 8:26 - 8:27
    a Planned Parenthood,
  • 8:27 - 8:29
    a cannabis shop,
  • 8:29 - 8:30
    a strip club;
  • 8:31 - 8:35
    every single person's public movements,
    habits and associations
  • 8:35 - 8:37
    documented and catalogued,
  • 8:37 - 8:39
    not on one day, but on every day,
  • 8:39 - 8:41
    merely with the push of a button.
  • 8:42 - 8:45
    This kind of totalizing mass surveillance
  • 8:45 - 8:48
    fundamentally threatens
    what it means to live in a free society.
  • 8:48 - 8:51
    Our freedom of speech,
    freedom of association,
  • 8:51 - 8:53
    freedom of religion,
  • 8:53 - 8:54
    freedom of the press,
  • 8:54 - 8:55
    our privacy,
  • 8:55 - 8:57
    our right to be left alone.
  • 8:58 - 9:00
    You may be thinking,
  • 9:00 - 9:03
    "OK, come on, but there are tons
    of ways the government can spy on us."
  • 9:03 - 9:05
    And yes, it's true,
  • 9:05 - 9:07
    the government can track us
    through our cell phones,
  • 9:07 - 9:11
    but if I want to go to get an abortion,
  • 9:11 - 9:12
    or attend a political meeting,
  • 9:12 - 9:17
    or even just call in sick
    and play hooky and go to the beach ...
  • 9:17 - 9:18
    (Laughter)
  • 9:18 - 9:20
    I can leave my phone at home.
  • 9:21 - 9:23
    I cannot leave my face at home.
  • 9:25 - 9:28
    And that brings me
    to my second primary concern:
  • 9:28 - 9:31
    How we might meaningfully
    regulate this technology.
  • 9:32 - 9:36
    Today, if the government wants to know
    where I was last week,
  • 9:36 - 9:41
    they can't just hop into a time machine
    and go back in time and follow me.
  • 9:42 - 9:44
    And they also, the local police right now,
  • 9:44 - 9:48
    don't maintain any centralized
    system of tracking,
  • 9:48 - 9:51
    where they're cataloging every person's
    public movements all the time,
  • 9:51 - 9:54
    just in case that information
    some day becomes useful.
  • 9:55 - 9:58
    Today, if the government
    wants to know where I was last week,
  • 9:58 - 10:00
    or last month or last year,
  • 10:00 - 10:02
    they have to go to a judge, get a warrant
  • 10:02 - 10:04
    and then serve that warrant
    on my phone company,
  • 10:04 - 10:08
    which by the way, has a financial interest
    in protecting my privacy.
  • 10:09 - 10:11
    With face surveillance,
  • 10:11 - 10:13
    no such limitations exist.
  • 10:13 - 10:18
    This is technology that is 100 percent
    controlled by the government itself.
  • 10:19 - 10:23
    So how would a warrant requirement
    work in this context?
  • 10:24 - 10:26
    Is the government going to go to a judge
  • 10:26 - 10:27
    and get a warrant,
  • 10:28 - 10:30
    and then serve the warrant on themselves?
  • 10:30 - 10:32
    That would be like me giving you my diary,
  • 10:32 - 10:35
    and saying, "Here,
    you can hold on to this forever,
  • 10:35 - 10:37
    but you can't read it
    until I say it's OK."
  • 10:38 - 10:39
    So what can we do?
  • 10:41 - 10:43
    The only answer to the threat
  • 10:43 - 10:47
    posed by the government's use
    of face surveillance
  • 10:47 - 10:52
    is to deny the government the capacity
    to violate the public's trust,
  • 10:52 - 10:54
    by denying the government the ability
  • 10:54 - 10:57
    to build these in-house
    face-surveillance networks.
  • 10:58 - 11:00
    And that's exactly what we're doing.
  • 11:01 - 11:04
    The ACLU is part of a nationwide campaign
  • 11:04 - 11:08
    to pump the brakes on the government's use
    of this dangerous technology.
  • 11:08 - 11:10
    We've already been successful,
  • 11:10 - 11:13
    from San Francisco
    to Somerville, Massachusetts,
  • 11:13 - 11:15
    we have passed municipal bans
  • 11:15 - 11:17
    on the government's
    use of this technology.
  • 11:17 - 11:20
    And plenty of other communities
    here in Massachusetts
  • 11:20 - 11:21
    and across the country
  • 11:21 - 11:22
    are debating similar measures.
  • 11:22 - 11:26
    Some people have told me
    that this movement is bound to fail.
  • 11:27 - 11:28
    That ultimately,
  • 11:28 - 11:30
    merely because the technology exists,
  • 11:30 - 11:33
    it will be deployed in every context
  • 11:33 - 11:36
    by every government everywhere.
  • 11:38 - 11:40
    Privacy is dead, right?
  • 11:40 - 11:42
    So the narrative goes.
  • 11:43 - 11:45
    Well, I refuse to accept that narrative.
  • 11:45 - 11:47
    And you should, too.
  • 11:48 - 11:52
    We can't allow Jeff Bezos or the FBI
  • 11:52 - 11:56
    to determine the boundaries
    of our freedoms in the 21st century.
  • 11:57 - 12:00
    If we live in a democracy,
  • 12:00 - 12:02
    we are in the driver's seat,
  • 12:02 - 12:04
    shaping our collective future.
  • 12:05 - 12:07
    We are at a fork in the road right now.
  • 12:07 - 12:10
    We can either continue
    with business as usual,
  • 12:10 - 12:14
    allowing governments to adopt and deploy
    these technologies unchecked,
  • 12:14 - 12:17
    in our communities, our streets
    and our schools,
  • 12:17 - 12:22
    or we can take bold action now
  • 12:22 - 12:26
    to press pause on the government's use
    of face surveillance,
  • 12:26 - 12:28
    protect our privacy
  • 12:28 - 12:31
    and to build a safer, freer future
  • 12:31 - 12:33
    for all of us.
  • 12:33 - 12:34
    Thank you.
  • 12:34 - 12:36
    (Applause and cheers)
