thanks for watching techwiki click the subscribe button then enable

00:00:03.200 --> 00:00:09.599
notifications with the bell icon so you won't miss any future videos so

00:00:07.440 --> 00:00:12.719
smartphones are pretty great right when you're out looking for the nearest

00:00:11.040 --> 00:00:17.199
all-night dumpling house that handy-dandy gadget in your pocket can

00:00:14.799 --> 00:00:21.279
use gps satellites to triangulate your position and direct you to the nearest

00:00:19.199 --> 00:00:25.439
food fix but what about the times when you'd rather not have the powers that be

00:00:23.359 --> 00:00:29.279
tracking your location maybe while you're sitting at home on your pc you

00:00:27.519 --> 00:00:32.239
fire up a mapping site in your web browser and

00:00:30.560 --> 00:00:38.160
wait a minute this thing doesn't have gps but it knows where i am down to a

00:00:34.880 --> 00:00:39.600
few meters what black magic is this well

00:00:38.160 --> 00:00:44.000
part of the way your location can be determined is by looking at your public

00:00:41.520 --> 00:00:48.879
ip address which every site you visit needs so that it knows where to send the

00:00:45.840 --> 00:00:50.800
data you request now each isp owns a

00:00:48.879 --> 00:00:54.879
certain range of ip addresses that correspond to different geographic

00:00:52.320 --> 00:00:59.280
locations often the particular city that they then assign to customers and since

00:00:56.960 --> 00:01:03.600
these addresses are assigned to your isp by large registries who make location

00:01:01.280 --> 00:01:07.200
data public it's easy for most sites to know your general location assuming you

00:01:05.680 --> 00:01:11.840
aren't using a vpn or something like that but that still doesn't explain how

00:01:09.680 --> 00:01:17.600
google maps can place a blue dot directly on my house i mean did larry

00:01:14.799 --> 00:01:22.159
page's personal helicopter just fly over well no unless you're using a desktop pc

00:01:20.400 --> 00:01:27.840
that's a few years old you're on a device that probably supports wi-fi and

00:01:25.360 --> 00:01:32.560
if your wi-fi router has ever connected to or even just been in range of a gps

00:01:30.400 --> 00:01:36.640
enabled gadget like a smartphone this is some next level stuff right here that

00:01:34.720 --> 00:01:41.439
phone will actually take note of the mac addresses the unique identifiers for

00:01:38.880 --> 00:01:44.960
every network-enabled device of all the wireless access points that are close

00:01:43.119 --> 00:01:48.720
enough for them to see then it'll for that information along

00:01:46.799 --> 00:01:53.119
with the phone's location to a database maintained by google if you're on

00:01:50.159 --> 00:01:57.759
Android or apple if you're on iOS whoa so these companies know where a

00:01:55.840 --> 00:02:01.920
huge number of the access points and routers floating around out there are

00:01:59.360 --> 00:02:05.920
located even if they aren't public and if a router gets moved to a different

00:02:03.520 --> 00:02:10.160
location these databases will likely be updated the next time a phone connects

00:02:07.759 --> 00:02:13.680
to it now obviously this is hugely convenient for using services that need

00:02:11.920 --> 00:02:18.480
to know your location when you don't have a good gps signal not to mention

00:02:16.000 --> 00:02:22.720
that gps alone is a battery hog and takes a lot longer to triangulate your

00:02:20.319 --> 00:02:26.160
location than the wi-fi database but i can't say i'd blame you if you

00:02:24.560 --> 00:02:30.480
weren't concerned about these companies keeping tabs on where every wireless

00:02:28.480 --> 00:02:34.640
router lives even the one that sits on your countertop in your kitchen so is

00:02:32.160 --> 00:02:39.599
there any way to opt out of this well yes in theory it seems like every other

00:02:37.360 --> 00:02:44.480
week we found out that oops it turns out we were logging all that data you told

00:02:40.959 --> 00:02:46.720
us not to anyway lol sorry but anyway in

00:02:44.480 --> 00:02:50.720
theory microsoft and google allow you to keep your router out of their location

00:02:48.160 --> 00:02:55.599
databases for google you can add underscore no map to the end of your

00:02:52.800 --> 00:02:59.360
wi-fi network's name or ssid while microsoft offers a web page where you

00:02:57.440 --> 00:03:02.159
can enter your ap's Mac Address which you can usually find on an attached

00:03:00.879 --> 00:03:08.480
sticker but there doesn't appear to be a similar escape hatch for apple at this time go

00:03:06.400 --> 00:03:13.760
figure and if you want to keep your client devices for being tracked again

00:03:10.959 --> 00:03:18.000
in theory disable location or location services on Android or iOS and don't

00:03:16.480 --> 00:03:22.080
allow your browser to send your location to websites if you're on a desktop pc

00:03:20.239 --> 00:03:26.080
now they're typically configured to ask you first anyway but it's worth double

00:03:24.080 --> 00:03:31.040
checking because if you do send your location out even using a vpn may not

00:03:28.959 --> 00:03:35.280
help obscure where you are if your pc has a wi-fi connection that can see

00:03:33.120 --> 00:03:39.920
surrounding networks even if you're only using a wired connection at the time so

00:03:37.920 --> 00:03:43.840
make sure that you disable your wi-fi outright if you're concerned about

00:03:41.440 --> 00:03:46.400
others knowing where you are and speaking about others knowing where

00:03:45.519 --> 00:03:52.959
you are this episode has been brought to you by tunnelbear the easy to use vpn app when

00:03:50.640 --> 00:03:57.040
people are shopping for a vpn one of the features they look for are kill switches

00:03:55.120 --> 00:04:01.200
before you connect to a network your device starts to send information about

00:03:58.879 --> 00:04:04.560
itself and what it wants to do it tries to establish connections with all sorts

00:04:02.879 --> 00:04:09.200
of things and there are a bunch of other devices trying to connect to yours kill

00:04:06.879 --> 00:04:13.439
switches stop this from happening before you connect to your vpn all of your

00:04:11.360 --> 00:04:17.759
traffic is unencrypted so in the few seconds it takes to connect you've

00:04:15.280 --> 00:04:22.160
probably already broadcast your ip maybe a few dns requests or even a search

00:04:19.840 --> 00:04:26.479
query vigilant bear from tunnelbear stops this from happening by blocking

00:04:24.240 --> 00:04:30.320
all inbound and outbound traffic so nothing leaks out before you connect

00:04:28.800 --> 00:04:34.080
this helps keep you private throughout your entire connection time if your

00:04:32.240 --> 00:04:38.240
connection goes down for some reason vigilant bearer kicks back in and stops

00:04:36.320 --> 00:04:42.720
all outbound inbound traffic until the connection comes back for a free trial

00:04:40.400 --> 00:04:45.280
