ืื ื™ ืจื•ืฆื” ืฉื–ื” ื™ื—ืœื—ืœ ืœืชื•ื“ืขื”:

First and foremost.

ื‘ืจืืฉ ื•ื‘ืจืืฉื•ื ื”.
00:50
So what that means is that when you're talking to your spouse,

someone could be listening.

ื”ืžื™ืฉื”ื• ื”ื–ื” ืขืฉื•ื™ ืœื”ื™ื•ืช ื”ืžืžืฉืœื” ืฉืœื›ื;

it could also be another government, a foreign intelligence service,

ื”ื•ื ืขืฉื•ื™ ืœื”ื™ื•ืช ืžืžืฉืœื” ืื—ืจืช, ืฉื™ืจื•ืช ื‘ื™ื•ืŸ ื–ืจ,

or a hacker, or a criminal, or a stalker

ื”ืืงืจ, ืคื•ืฉืข ืื• ืžืฆื™ืฆืŸ,
01:10
or any other party that breaks into the surveillance system,

ืื• ื›ืœ ื’ื•ืฃ ื ื•ืกืฃ ืฉืžืชืคืจืฅ ืœืžืขืจื›ืช ื”ืžืขืงื‘,

01:19
But while the telephone companies have built surveillance as a priority,

Silicon Valley companies have not.

ื”ื—ื‘ืจื•ืช ื‘ืขืžืง ื”ืกื™ืœื™ืงื•ืŸ - ืœื.
01:26
And increasingly, over the last couple years,
23
86523

ื•ื™ื•ืชืจ ื•ื™ื•ืชืจ, ื‘ืฉื ื™ื ื”ืื—ืจื•ื ื•ืช,

01:29
Silicon Valley companies have built strong encryption technology
24
89066

01:32
into their communications products
25
92752
1938
ื‘ืžื•ืฆืจื™ ื”ืชืงืฉื•ืจืช ืฉืœื”ืŸ,
01:34
that makes surveillance extremely difficult.

ืžื” ืฉืžืงืฉื” ื‘ืื•ืคืŸ ืงื™ืฆื•ื ื™ ืขืœ ื”ืžืขืงื‘.
01:37
For example, many of you might have an iPhone,

2174
ืœืžืฉืœ, ืœืจื‘ื™ื ืžื›ื ื™ืฉ "ืื™ื™ืคื•ืŸ",
01:39
and if you use an iPhone to send a text message

ื•ืื ืืชื ืžืฉืชืžืฉื™ื ื‘"ืื™ื™ืคื•ืŸ" ื›ื“ื™ ืœืฉืœื•ื— ืžืกืจื•ืŸ

102328
2177
ืœืื ืฉื™ื ืื—ืจื™ื ื‘ืขืœื™ "ืื™ื™ืคื•ืŸ",
01:44
those text messages cannot easily be wiretapped.

3010
ืœื ืงืœ ืœืฆื•ืชืช ืœืžืกืจื•ื ื™ื ืืœื”.
01:47
And in fact, according to Apple,
31
107563
1828
ืœืžืขืฉื”, ืœื“ื‘ืจื™ "ืืคืœ",
01:49
they're not able to even see the text messages themselves.

01:52
Likewise, if you use FaceTime to make an audio call
33

ื‘ื“ื•ืžื” ืœื›ืš, ืื ืืชื ืžืฉืชืžืฉื™ื ื‘"ืคื™ื™ืกื˜ื™ื™ื" ืœืฉื™ื—ื” ืงื•ืœื™ืช,
01:56
or a video call with one of your friends or loved ones,

ืื• ืœืฉื™ื—ืช ื•ื™ื“ืื• ืขื ืื—ื“ ืžื—ื‘ืจื™ื›ื ืื• ืื”ื•ื‘ื™ื›ื,
01:59
that, too, cannot be easily wiretapped.

ื’ื ื–ื” ืœื ื ื™ืชืŸ ืœืฆื™ืชื•ืช ื‘ืงืœื•ืช.
02:01
And it's not just Apple.

ื•ืœื ืจืง ื‘"ืืคืœ".
02:03
WhatsApp, which is now owned by Facebook

"ื•ื•ืื˜ืกืืค", ืฉื‘ื‘ืขืœื•ืช "ืคื™ื™ืกื‘ื•ืง",
02:05
and used by hundreds of millions of people around the world,

ื•ืฉืžืื•ืช ืžื™ืœื™ื•ื ื™ื ืื ืฉื™ื ืžืฉืชืžืฉื™ื ื‘ื” ื‘ื›ืœ ื”ืขื•ืœื,
02:08
also has built strong encryption technology into its product,

02:12
which means that people in the Global South can easily communicate
40

ื›ืœื•ืžืจ, ืื ืฉื™ื ื‘ื“ืจื•ื ื›ื“ื•ืจ ื”ืืจืฅ ื™ื›ื•ืœื™ื ืœืชืงืฉืจ ื‘ืงืœื•ืช
02:15
without their governments, often authoritarian,
41
135635
2810
ืžื‘ืœื™ ืฉืžืžืฉืœื•ืชื™ื”ื, ื”ืขืจื™ืฆื•ืช ื‘ื“"ื›,

wiretapping their text messages.

1734
ื™ืฆื•ืชืชื• ืœืžืกืจื•ื ื™ื ืฉืœื”ื.
02:21
So, after 100 years of being able to listen to any telephone call --
43
141599
4945
ืื– ืื—ืจื™ 100 ืฉื ื” ืฉืœ ื”ื™ื›ื•ืœืช ืœืฆื•ืชืช ืœื›ืœ ืฉื™ื—ืช ื˜ืœืคื•ืŸ --

anytime, anywhere --
44
146568
2554
ื‘ื›ืœ ื–ืžืŸ ื•ื‘ื›ืœ ืžืงื•ื --
02:29
you might imagine that government officials are not very happy.
45
149146
3131
ืชื•ื›ืœื• ืœืฉืขืจ ืฉืคืงื™ื“ื™ ื”ืžืžืฉืœ ืื™ื ื ืžืจื•ืฆื™ื ื‘ืžื™ื•ื—ื“.
02:32
And in fact, that's what's happening.
46
152301
1786
ื•ืœืžืขืฉื”, ื–ื” ืžื” ืฉืงื•ืจื”.
02:34
Government officials are extremely mad.
47
154111
2219
ืคืงื™ื“ื™ ื”ืžืžืฉืœ ื–ื•ืขืžื™ื ืžืื“.
02:36
And they're not mad because these encryption tools are now available.
48
156354
3875
ื•ื”ื ืœื ื–ื•ืขืžื™ื ื›ื™ ื›ืœื™ ื”ื”ืฆืคื ื” ื”ืืœื” ื–ืžื™ื ื™ื ื›ื™ื•ื.
02:40
What upsets them the most
49
160253
1818
ืžื” ืฉื”ื›ื™ ืžืจื’ื™ื– ืื•ืชื
02:42
is that the tech companies have built encryption features into their products
50
162095
4167
ื”ื•ื ืฉื—ื‘ืจื•ืช ื”ื˜ื›ื ื•ืœื•ื’ื™ื” ืฉื™ืœื‘ื• ืชื›ื•ื ื•ืช ื”ืฆืคื ื” ื‘ืžื•ืฆืจื™ื”ืŸ
02:46
and turned them on by default.
51
166286
1873
ื•ื”ืคืขื™ืœื• ืชื›ื•ื ื•ืช ืืœื” ื›ื‘ืจื™ืจืช-ืžื—ื“ืœ.
02:48
It's the default piece that matters.
52
168547
1970
ื”ืงื˜ืข ืฉืœ "ื‘ืจื™ืจืช-ื”ืžื—ื“ืœ" ื”ื•ื ื”ื—ืฉื•ื‘.
02:50
In short, the tech companies have democratized encryption.
53
170541
3775
ื‘ืงืฆืจื”, ื—ื‘ืจื•ืช ื”ื˜ื›ื ื•ืœื•ื’ื™ื” ืขืฉื• ื“ืžื•ืงืจื˜ื™ื–ืฆื™ื” ืœื”ืฆืคื ื”.
02:55
And so, government officials like British Prime Minister David Cameron,
54
175165
3797
ื•ื›ืš, ืคืงื™ื“ื™ ืžืžืฉืœ ื›ืžื• ืจื•ื”"ืž ื”ื‘ืจื™ื˜ื™, ื“ื™ื™ื•ื™ื“ ืงืžืจื•ืŸ,
02:58
they believe that all communications -- emails, texts, voice calls --
55
178986
4847
ืžืืžื™ื ื™ื ืฉื›ืœ ื”ืชืงืฉื•ืจืช -- ื“ื•ื"ืœ, ืžืกืจื•ื ื™ื, ืฉื™ื—ื•ืช ืงื•ืœื™ื•ืช --
03:03
all of these should be available to governments,
56
183857
2588
ื›ืœ ืืœื” ืฆืจื™ื›ื™ื ืœืขืžื•ื“ ืœืจืฉื•ืช ื”ืžืžืฉืœื”,
03:06
and encryption is making that difficult.
57
186469
2102
ื•ื”ื”ืฆืคื ื” ืžืงืฉื” ืขืœ ื–ื”.
03:09
Now, look -- I'm extremely sympathetic to their point of view.
58
189478
3384
ืจืื•, ืื ื™ ืžืœื ืื”ื“ื” ืœื ืงื•ื“ืช ื”ื”ืฉืงืคื” ืฉืœื”ื.
03:12
We live in a dangerous time in a dangerous world,
59
192886
2532
ืื ื• ื—ื™ื™ื ื‘ืขื™ื“ืŸ ืžืกื•ื›ืŸ ื•ื‘ืขื•ืœื ืžืกื•ื›ืŸ,
03:15
and there really are bad people out there.
60
195442
2000
ื•ื™ืฉ ื‘ืืžืช ืื ืฉื™ื ืจืขื™ื.
03:17
There are terrorists and other serious national security threats
61
197466
3115
ื™ืฉ ื˜ืจื•ืจื™ืกื˜ื™ื ื•ืื™ื•ืžื™ื ื—ืžื•ืจื™ื ื ื•ืกืคื™ื ืขืœ ื”ื‘ื˜ื—ื•ืŸ ื”ืœืื•ืžื™,
03:20
that I suspect we all want the FBI and the NSA to monitor.
62
200605
3977
ืฉืื ื™ ื—ื•ืฉื“ ืฉื›ื•ืœื ื• ืจื•ืฆื™ื ืฉื”ื‘ื•ืœืฉืช ื•ื”ืกื•ื›ื ื•ืช ืœื‘ื˜ื—ื•ืŸ ืœืื•ืžื™ ื™ื ื˜ืจื•.
03:25
But those surveillance features come at a cost.
63
205345
2703
ืื‘ืœ ืœืืžืฆืขื™ ื”ืžืขืงื‘ ื”ืืœื” ื™ืฉ ืžื—ื™ืจ.
03:29
The reason for that is
64
209357
1155
ื”ืกื™ื‘ื” ืœื›ืš ื”ื™ื
03:30
that there is no such thing as a terrorist laptop,
65
210536
2486
ืฉืื™ืŸ ื“ื‘ืจ ื›ื–ื”, "ืžื—ืฉื‘ ื ื™ื™ื“ ืฉืœ ืžื—ื‘ืœ",
ืื• "ื˜ืœืคื•ืŸ ื ื™ื™ื“ ืฉืœ ืกื•ื—ืจ ืกืžื™ื".
03:33
or a drug dealer's cell phone.
66
213046
1507
03:34
We all use the same communications devices.
67
214902
2963
ื›ื•ืœื ื• ืžืฉืชืžืฉื™ื ื‘ืื•ืชื ืžื›ืฉื™ืจื™ ืชืงืฉื•ืจืช.
03:38
What that means is that if the drug dealers' telephone calls
68
218577
3675
ื•ื–ื” ืื•ืžืจ ืฉืื ื”ืฉื™ื—ื•ืช ืฉืœ ืกื•ื—ืจ ื”ืกืžื™ื
03:42
or the terrorists' telephone calls can be intercepted,
69
222276
2545
ืื• ืฉืœ ื”ืžื—ื‘ืœ ื ื™ืชื ื•ืช ืœื™ื™ืจื•ื˜,
03:44
then so can the rest of ours, too.
70
224845
1996
ื›ืš ื’ื ื”ืฉื™ื—ื•ืช ืฉืœ ื›ื•ืœื ื•.
03:46
And I think we really need to ask:
71
226865
1627
ื•ืœื“ืขืชื™, ืขืœื™ื ื• ืœืฉืื•ืœ ื‘ื›ื ื•ืช:
03:48
Should a billion people around the world be using devices
72
228516
3127
ื”ืื ืžื™ืœื™ืืจื“ ื‘ื ื™-ืื“ื ื‘ืจื—ื‘ื™ ื”ืขื•ืœื

03:51
that are wiretap friendly?
73
231667
1419
03:55
So the scenario of hacking of surveillance systems that I've described --
74
235407
3748
ืื– ื”ืชืกืจื™ื˜ ืฉืœ ืคืจื™ืฆื” ืœืžืขืจื›ื•ืช ืžืขืงื‘, ืฉืชื™ืืจืชื™,
03:59
this is not imaginary.
75

04:01
In 2009,
