WEBVTT 0 00:01.400 --> 00:08.160 In this lecture, I'll show you how to protect our privacy by using disposable phone numbers or second 1 00:08.220 --> 00:09.060 number apps. 2 00:09.540 --> 00:16.050 Many websites ask you to provide some form of verification when you want to sign up to a service, 3 00:16.110 --> 00:21.480 including shopping sites, email accounts, gaming services, blogs and so on. 4 00:21.900 --> 00:26.080 A basic form of verification is by supplying an email address. 5 00:26.580 --> 00:34.020 But other forms of verification can try to be more secure by requiring you to enter more personal information 6 00:34.260 --> 00:37.440 such as a name, an address or a birth date. 7 00:37.980 --> 00:45.360 Some services try to identify you as a legitimate user by using phone verification, which usually comes 8 00:45.480 --> 00:46.800 in a form of an 9 00:46.800 --> 00:46.960 sms 10 00:46.960 --> 00:50.940 message with a secret code sent to your mobile phone. 11 00:52.010 --> 00:59.900 Some important services like our banking application might be more secure by using two factor authentication 12 01:00.290 --> 01:06.520 and in this case, it would make sense to use your real phone number, but for other things that are 13 01:06.530 --> 01:07.490 not so important 14 01:07.820 --> 01:15.080 or for those that require a one time verification, using a number that is not tied to your real identity 15 01:15.320 --> 01:16.280 would be preferrable. 16 01:16.880 --> 01:23.840 Thankfully, there are websites that offer services where you can read a text message that was sent 17 01:23.900 --> 01:24.770 to that number. 18 01:26.020 --> 01:33.850 This is an online receive service ;to use it, all you have to do is simply give the provided no. to the 19 01:33.850 --> 01:40.480 service or individual that requires some number to send you the message. After a short period of time 20 01:40.750 --> 01:43.750 the message will be displayed on a Web page. 21 01:44.260 --> 01:50.080 Please note that these accounts are not private or secure and can be seen by anyone. 22 01:50.350 --> 01:54.430 So make sure no personal information is going to be received. 23 01:55.560 --> 01:57.750 Let's take a look at this service. 24 01:58.680 --> 02:00.320 I've chosen it randomly. 25 02:01.440 --> 02:05.860 If by the time you will be watching this video, it won't work anymore, 26 02:06.030 --> 02:10.530 you should know that there are lots of other such services on the Internet. 27 02:10.950 --> 02:12.780 Just search for another one! 28 02:14.120 --> 02:21.830 Like select a number, for example, this UK number, and we see a list of the last 50 sms messages 29 02:21.920 --> 02:22.520 received. 30 02:23.950 --> 02:29.050 As I'm sure you've noticed, they are many verification codes from different services: 31 02:30.210 --> 02:32.150 DENT, Amazon. 32 02:33.390 --> 02:34.980 Lime or Uber. 33 02:36.090 --> 02:40.640 To test it, I'm sending an estimates to that number from my phone. 34 02:41.670 --> 02:45.150 I'm writing:" just a test, it's me, 1, 2, 3" 35 02:47.330 --> 02:48.920 Now I'm writing the message. 36 02:50.410 --> 02:54.490 I've sent the sms and I'll update the messages. 37 02:55.590 --> 02:58.860 And look, this is the message I've just sent. 38 03:00.110 --> 03:04.900 Another way to protect our privacy is with a second phone number app. 39 03:05.650 --> 03:12.580 These apps let you create temporary numbers to be given up to unknown contacts so that you can keep 40 03:12.580 --> 03:14.350 your personal number private. 41 03:14.920 --> 03:22.060 They use voice over IP technology, but unlike other voice over IP services, like, for example,Whatsup 42 03:22.060 --> 03:30.160 Facebook or Skype, these service providers have a block of phone numbers that can be assigned to 43 03:30.160 --> 03:30.880 its users. 44 03:31.600 --> 03:36.340 Once you sign up, the app will assign you one of its phone numbers. 45 03:36.640 --> 03:43.720 You can use that number like you would any other phone, number to make or receive phone calls and to 46 03:43.720 --> 03:49.810 send or receive a sms! Note that since these apps use voice over IP 47 03:50.230 --> 03:52.750 you will need to be connected to the Internet. 48 03:53.990 --> 04:01.070 OK, that's all! Now you know what to do when a service will be asking for your phone number to verify 49 04:01.070 --> 04:01.250 you.
