you're up to date now on d w news don't forget you can always get the latest news and information on our website just go to d w dot com stay tuned for a shift living in the digital age that's coming up next after a short break omarion adelstein i mean all of us here in berlin thanks so much for watching. they were forced into a nameless mass. their bodies your tools with. the history of the slave trade east africa's history. into some greek for

power and profit plummeted an entire continent into chaos and violence. this is the journey back into the history of slavery. i think we will truly be making progress when we all accept the history of slavery as all of our history. our documentary series slavery routes starts march 9th on g.w. . fridges that know it was at the door talking losses and robots that mow the lawn on their own smart devices are meant to make our lives easier but they also gathering all private data the internet of things the smart but how secure is it i want all because the day on shift.

i old c. see or the internet of things is a network of devices that can communicate via built in many computers for example has integrated senses that monitor and regulate room temperature that can save heating costs of vacuum cleaners that operate independently can save us time boys assistance always have an open ear for us and can even tell other devices what we want by the way what do you think alexa is used most for they've limp head of amazon hardware has some interesting news customers ask echo over a 1000000000 times a year. this alexa what time is. the talking clock. the internet of things has a lot more to offer from time sensors that measure quality to ring networks to surveillance systems for industrial plants a recent study expects that over 50000000000 devices and sensors will be connected

by 2022 professor from the visited specializes in the internet of things. professors much has been studying the internet of things for over 10 years and. he's fascinated by the idea of making everyday objects smart. consider the light bulb you can control it with a switch on the wall or you could use your phone. you might want to add features like making a light flash when a storm warning is issued. but then your light needs to be able to receive that information from the web it's not stored locally. so your light has to be able to communicate with the cloud. industry promises smart devices to make life easier like with autonomy.

tracking cleaners that run on their own and automatically adjust the room temperature as soon as everyone is left the house. a smart fridge that monitors which groceries are running out can be very inconvenient imagine being out of butter and then the doorbell rings with a fresh delivery of more butter but this also lets companies analyze which products you consume. the data collected in transmitted is mostly invisible to ordinary users the same goes for the software built into their devices. to the data collected and in the worst case you can remotely control the smart device these are the largest concerns materiel has with this new technology. right now the biggest challenge the internet of things faces is security and privacy imagine someone with access to your stove they could cause it to overheat and maybe even

start a fire in your home. or someone with control over a power plant could cut the power to an entire city. the possibilities seem endless but the risks involved and not to be taken lightly users should think twice about how much small technology they want in their homes families 11 is not too worried they enjoy the convenience and futuristic fear the smog network provides i would like to see even more technology online of mine wouldn't i want my house to be able to tell when i get out of bed when i come downstairs i want my favorite radio station to start playing my favorite coffee brewing out of it's cold outside my car to automatically start heating up and it. can already remotely control who has access to his home he has a smart door his children don't need a key to get in they simply scan their fingerprints. and it's not home i

can see if my kids are home from them this camera has facial recognition. it's. very interesting.

they all had to confess to analyzing. how. these digital. times pick up on things. constantly checking. understand. now people using this technology.

i default my privacy being the default setting people who don't mind their actions being recorded to improve their experience can still change their settings or use a smart technology at home should really know what they're dealing with security expert martin shadow police small technology required smart handling the monkey fun thought if you're responsible for a household full of smart devices then you've basically become a system administrator like the ones that many choose data centers for via acknowledge that means you need to treat your home like one cataloguing the devices you are installing security patches checking for software updates changing passwords elsewhere and perhaps even setting up protocols like to make sure there were no hacker templates. and principals who got good point security

analysts say the number of cyber attacks on i have to devices is on the rise in the 1st half of 21000 there were more than 2900000000 hacking attempts that's 3 times more than last year one hacker shows how simple hacking and be. launches to your floor. says spy on you. 3 hackers have commandeered the device gaining access was pretty straightforward. by this manufacture i connected through one data cloud for control that's me with. a slight change to the source code was all it took to access the controls and camera. the vacuum cleaner receives its commands through a built in microcontroller connected to the internet. security caps make the entire network devices vulnerable. i can start. with

and then i can look which device is there reason. to do. so it's like it's related to. the bad guys. but there is no limit the problem is just one device can compromise the entire system no matter if it's a home or industrial network as soon as get into one device they have access to all other unsecured devices on the network and they can reprogram those devices to launch new attacks that makes it all the more important to understand the technology behind the internet of things but recommends open source solutions they don't rely on just one manufacturer for security or data protection. with bold names riot. well riot is meant to become the new global operating system for the internet of things we provide the apps users need for that. if you're interested in

the internet of things and want to make your devices smart then it's important to use open source solutions that aren't bound to a specific manufacturer. and always be aware of which apps you're using and what private data they require. one possible solution is the operating system ryan developed at 3 european universities the great source code is openly accessible so anyone can check it and modify it to their own needs but that won't let users program their own devices yet they need other apps to do that. yes delish wants to offer these apps on graph store and app store for the internet of things currently it's still being tested but in the future it will let users download all kinds of apps from their smart devices so they can individually tailor their devices features. for

the internet of things operates across a lot of different devices so it's not easy to make sure the software always runs smoothly there's not just 3 or 4 platforms to consider there's thousands ideally you want your software to run on all of them. riot focuses on small processors with low storage capacity and performance and minimal mostly battery power and energy consumption there's 2 reasons why much yes neelesh prefers these kinds of applications. you know about that well 1st of all every object requires musical space that you might not always have. secondly each additional component costs extra when you manufacture small scale devices you can't use too much space and you need to be cost effective and. the industry is also very interested in open source io t. technology one car manufacturer is currently testing digital keys that run with the

riot operating system smarts and say. one main software that keeps my network safe and make sure my o.t. devices work together smoothly and that's how i would want my smartphone to be a reality is a big deal. friend manufacturers are reluctant to hand over their software and aside from that i think i owe t.d. vies this should offer more than just convenience they should promote sustainability a smart thermostat that helps save energy great smart feed of a mad dog no thanks otherwise it ended all things becomes the internet of jack what's your opinion how smart do you want your data data be join the discussion for example shia buy and see their.

game is used to dominate nairobi and now it's going to feed the artists. the few small profit that you are just sitting in a studio and doing your small small blame to the sun we take the awful to the for the obvious street art is transforming this city and if people together they're making something new 77 percent. next on d w. this coupled with the. motor journalist by sally the current champion funny took so. long to do so 6 o 4 in a vintage depot the favorite with the political elite in the former east germany. ronny has to prove his chauffeur skills on the race track. his current speed read.

no problem 16 t.w. . it doesn't buy you don't know it's not easy to go to another country you know nothing about the wife and i don't do this because we can't stay in venezuela i'm not going on the supply that. closely global news that matters d.w. made for mines. hey there it's good to have you here on the 77 percent the show that occupies the voice of off because you my name is one you cobol are good to have you with this. today it's all about young africans who should all future with digital technologies and it's a special show too because we have an exciting.
