2 00:00:00,280 --> 00:00:03,480
\r
3 Nos oignons contributes to an Internet
\r
6 00:00:03,600 --> 00:00:06,840
\r
7 where we have more control over
\r
8 the information that concerns us.
\r
11 00:00:07,440 --> 00:00:10,280
\r
12 When you read a newspaper,
\r
13 it is a one-way reading.
\r
16 00:00:10,680 --> 00:00:13,680
\r
17 The newspaper is not reading us
\r
18 while we are reading it.
\r
21 00:00:14,320 --> 00:00:17,240
\r
23 the same newspaper online,
\r
26 00:00:17,400 --> 00:00:18,440
\r
27 this is what happens.
\r
30 00:00:19,400 --> 00:00:21,440
\r
31 The site learns which article we read,
\r
34 00:00:21,480 --> 00:00:22,920
\r
35 how much time we spend on it,
\r
38 00:00:23,120 --> 00:00:24,360
\r
39 and which Internet connection we used
\r
42 00:00:24,640 --> 00:00:27,000
\r
43 and therefore where we are.
\r
46 00:00:27,880 --> 00:00:31,560
\r
47 The advertising agencies used on
\r
48 the site learn all this too.
\r
51 00:00:32,000 --> 00:00:34,760
\r
52 And, as they are used by several sites
\r
55 00:00:35,720 --> 00:00:38,520
\r
57 throughout our press review.
\r
60 00:00:39,400 --> 00:00:40,480
\r
61 And it doesn't stop there
\r
64 00:00:41,520 --> 00:00:45,120
\r
65 If a site uses Google's analytics
\r
69 00:00:45,600 --> 00:00:48,920
\r
70 displays a Facebook "Like" button
\r
71 or a Twitter "Share" button,
\r
74 00:00:49,240 --> 00:00:50,680
\r
75 these companies are also tracking us.
\r
78 00:00:51,400 --> 00:00:54,880
\r
79 And just by logging into your GMail,
\r
80 Facebook or Twitter account
\r
83 00:00:55,120 --> 00:00:56,440
\r
84 they can link our identity
\r
87 00:00:56,480 --> 00:01:00,000
\r
88 to the sites we visit,
\r
92 00:01:00,080 --> 00:01:01,520
\r
93 how long we spend on them
\r
96 00:01:02,280 --> 00:01:04,160
\r
97 or where we use them from.
\r
100 00:01:04,800 --> 00:01:07,000
\r
101 Yet this is not acceptable.
\r
104 00:01:07,120 --> 00:01:08,520
\r
105 It is simply none of their business.
\r
108 00:01:09,280 --> 00:01:10,520
\r
109 These informations should not
\r
112 00:01:10,520 --> 00:01:13,320
\r
113 be shared without our consent.
\r
116 00:01:15,120 --> 00:01:16,760
\r
117 Most laws that seek to protect us
\r
120 00:01:16,760 --> 00:01:17,840
\r
124 00:01:18,240 --> 00:01:21,320
\r
125 do require us to be consulted
\r
126 about the use of these data.
\r
129 00:01:22,360 --> 00:01:25,720
\r
130 But by that time, they have already
\r
131 been transmitted by our browsers.
\r
134 00:01:26,320 --> 00:01:28,080
\r
135 So, the sites ask us
\r
138 00:01:28,160 --> 00:01:28,760
\r
142 00:01:28,880 --> 00:01:29,800
\r
146 00:01:31,600 --> 00:01:32,800
\r
147 But we can't really check,
\r
150 00:01:32,840 --> 00:01:36,360
\r
151 and it doesn't protect us from
\r
152 bad configuration or hacking.
\r
155 00:01:38,960 --> 00:01:41,600
\r
156 Shouldn't this information be shared
\r
157 only if we want it?
\r
160 00:01:43,720 --> 00:01:46,080
\r
161 The Tor Browser does just that.
\r
164 00:01:46,640 --> 00:01:49,680
\r
165 It isolates our connections to each site.
\r
168 00:01:50,200 --> 00:01:53,040
\r
169 So, it's impossible to track us
\r
170 from site to site.
\r
173 00:01:53,480 --> 00:01:56,120
\r
174 Even if I'm logged into GMail in a tab
\r
177 00:01:56,840 --> 00:01:59,720
\r
178 Google won't know that
\r
179 I'm visiting other sites.
\r
182 00:02:01,200 --> 00:02:08,040
\r
183 Another thing the Tor Browser does
\r
184 is to make everyone "look" the same.
\r
187 00:02:08,320 --> 00:02:12,360
\r
188 Our system information is replaced
\r
189 with generic information.
\r
192 00:02:13,280 --> 00:02:15,720
\r
193 This makes us more difficult to discern.
\r
196 00:02:16,360 --> 00:02:21,280
\r
197 The sites and their partners will only
\r
198 record being visited by a Tor browser.
\r
201 00:02:22,360 --> 00:02:23,840
\r
202 But for this to be possible,
\r
206 00:02:24,320 --> 00:02:28,400
\r
207 to get around a limit of the
\r
208 historical functioning of the Internet.
\r
211 00:02:29,640 --> 00:02:33,120
\r
212 When a communication
\r
213 is done on the Internet
\r
216 00:02:33,240 --> 00:02:35,840
\r
217 computers learn their location
\r
221 00:02:36,000 --> 00:02:38,720
\r
222 as they exchange information.
\r
225 00:02:38,840 --> 00:02:42,080
\r
226 Except that this is problematic.
\r
229 00:02:42,120 --> 00:02:45,720
\r
230 It forces us to disclose a very
\r
231 personal information :
\r
234 00:02:45,760 --> 00:02:48,320
\r
235 the connection we use,
\r
238 00:02:48,400 --> 00:02:50,280
\r
239 from which everyone can know
\r
243 00:02:50,480 --> 00:02:54,600
\r
244 The Tor network ensures that this information
\r
245 does not leak without our consent.
\r
248 00:02:54,800 --> 00:02:58,120
\r
249 By bouncing our connections
\r
252 00:02:58,240 --> 00:03:02,040
\r
253 through a network of thousands of relays,
\r
254 it hides our location.
\r
257 00:03:03,040 --> 00:03:06,800
\r
258 Indeed, for each of our connections,
\r
259 three relays are chosen at random
\r
262 00:03:07,240 --> 00:03:11,440
\r
263 and thanks to a system
\r
264 of onion layer encryption
\r
267 00:03:11,560 --> 00:03:13,760
\r
268 It is impossible for intermediaries
\r
269 to see the entire communication.
\r
272 00:03:15,520 --> 00:03:17,600
\r
273 When you connect to a site with Tor
\r
276 00:03:18,040 --> 00:03:21,600
\r
277 the third relay - also known as the
\r
278 exit node - knows our destination,
\r
281 00:03:21,680 --> 00:03:25,520
\r
282 but it can't know where we are.
\r
285 00:03:25,640 --> 00:03:28,000
\r
286 This is where Nos oignons comes in.
\r
289 00:03:28,280 --> 00:03:30,880
\r
290 Some of these exit nodes
\r
291 are those of Nos oignons.
\r
294 00:03:31,800 --> 00:03:35,440
\r
295 The association contributes
\r
296 to the Tor network
\r
299 00:03:35,560 --> 00:03:38,800
\r
300 by operating several good capacity
\r
301 relays, located in France.
\r
304 00:03:39,360 --> 00:03:42,080
\r
305 Our relays are funded by donations
\r
306 from individuals like you,
\r
309 00:03:42,280 --> 00:03:44,000
\r
310 organizations, and businesses.
\r
313 00:03:45,000 --> 00:03:47,600
\r
314 Join us in supporting the Tor network
\r
317 00:03:47,680 --> 00:03:50,360
\r
318 and keeping the Internet
\r
319 the way it should be.
\r
