corona crisis you can find more information online at v.w. dot com and on t.w. social media channels. where and when exactly tracing down every single person who's come in contact with a coronavirus kariya surely that's something only take can self that says we must be able to trace every infection chain we are working on an app that can help us do that. but that's got civil rights activists worried. that there is a real witness that these kinds of surveillance systems will assist all to this phase of the president it is our digital privacy. steak oh good we sell for this

crisis. what come to kobe to 900 special here and e.w. news on one of cajones good to have you with us the technology has been a blessing during this pandemic in many ways speed working from home or staying in touch with friends and family and take helps us keep track of the virus in australia launched a corona tracing app it records who's been in contact with whom so they can be warned if someone's infected china is using apps to help prevent a 2nd wave of infections uses scanned q.r. codes and public places to share information about their health south korea has developed smartphone applications that help authorities track the movements of infected people which are published online and the government in india has also launched an app that lets people know if there's an incident of the coronavirus
8:18 am
nearby one of the worst affected countries italy is also working on an app the tracks people who've come in contact with a confirmed case and germany is developing a system of voluntary information sharing. well the word voluntary may seem odd given the scale of the pandemic but germans really cherish their data privacy after weeks of partial lockdown however they're also keen to get back to normal life and an app could be key in getting there. getting the virus and going into self isolation is a challenge for anyone but data protection is just as much an issue for many germans during this crisis that's hardly surprising given the 2 periods of mass surveillance in the country's history. that's why those behind the corona rap have to guarantee data won't be stored centrally essentially the app will work like a kind of diary noting which phones come close to each other and for how long the

phone 6 changed key codes don't directly reveal their own as if someone contracts the virus their code is made available to other uses they can then check regularly to see if they're affected only information stays on the individual phones. that's rather different to china a country west of aliens is part of everyday life the large chinese telecommunications companies granted to authorities access to their databases at the beginning of february allowing them to track individuals movements thanks to centralized data storage chinese authorities are able to see precisely where those infected spend that time and also see where groups of people have gathered. all of this allows them to identify individuals as potential spreaders of the virus but for democratic societies that's unthinkable for many people like here in germany anything alluding to surveillance is unacceptable. that attitude has lead
8:20 am
tech giants apple and google to reject centralized tracing apps and focus instead on developing tools for decentralized versions of tracing up in singapore for example centrally collects the names and ages of its uses but apple will play ball and say the app only works on i phones if the user keeps it permanently open as a result just 20 percent of singapore rians use it. aided by big tex new acceptable tools german app developers could have a corona wrap ready by june or. of a more i'm joined by martin digging a post-doctoral research or a university in borehole where he specializes in data protection good to have you with us this tell you how can a tracing app ensure data privacy on the one hand and limit the spread of the virus . yes 1st of all thanks for having me so that we've seen
8:21 am
around the world over the last weeks. trek the uses every movement to do where they're been met except for hunter tracing to work at the airport to know all the specific details of who you met and where but it's only important to know that you have met a person that was later. infected so it's not important to actually know all the details but only to know that you have met someone and worked with the current debate in germany is all about europe and that's what we that what they're trying to implement with the latest version exactly and this is why it takes a little bit longer than and some other countries i mean i personally i have nothing to hide at least i think so but given the implications of this the app how foolproof is it i mean could the epa centerfolds info about someone being infected . so 1st of all they have both were not protect your right because that's one of
8:22 am
the problems with the with the coronavirus is that you often don't know that you were infected or somebody is infected so it's only in the end will only help to inform your afterwords that you have been infected person and the other the problem is with the data security and that's what you've also mentioned and that's what it what researchers are working on what the group of researchers working on at the moment to ensure that for example only health authorities are able to say who was infected who is not so or that you are not able if you use the air that you can and . ed data for example you know i could make a list of people that i don't like it put them on the list and say i met those people and when i would think that they all have to go to current time right that's what we want to prevent and that's why where security is important but this is heaven for tech savvy people but of course given that it'll still take a while until there is
8:23 am
a vaccine would you say that tech is key for us to get back to a normal life. so the president writes of i think the word hope limited spread of despair of the rough iris but overall i think sometimes people have too many hopes in this technology or because it can only be one part of the puzzle to solve this crisis and to limit the spread of the virus. after all we don't actually know whether these apps will work because the effort of been tested for a long time effect in singapore where they had this or that out like this for for some weeks already it didn't help at all because the people who were that where the virus is spreading now didn't have any chance to do distancing and also there are discussions about how many people can actually install that because their technical requirements you have to have a phone that is not older than a few years and that's not what i read in terms of their discussion discussing that
8:24 am
approx 80 to 90 percent of the people who actually have the technical requirements will have a phone that could work and then you would still need enough people that were actually install it ok so what you're telling us there's still a long way to go but it's worth taking the time for it to to make it work matinée degel in there from rio the university in thank you so much for your time. thanks by. all this is still so many questions and many more questions that you all have about the coronavirus now luckily we do have an expert in house it's time now to get some more answers from our science editor derek williams. can taking off your shoes when inside help reduce the transmission of hiv 19. great question we're constantly hearing about how infectious droplets that are coughed up or sneezed out subtle pretty quickly to
8:25 am
the ground where of course they could end up on the soles of your shoes now a chinese study in a 6 oared in bu han found the virus on the shoes of staff about half the time but but that's a hospital in the midst of a pandemic so it's kind of to be expected in other settings it's going to be much more rare i didn't find any documented cases where shoes had been shown to be a means of transmission but plenty of doctors are saying that even if the danger is slight it certainly can't hurt to leave your shoes at the front door when you come home especially if you live in a household with small children who spend lots of time on the floor after all stars have to isn't the only pathogen out there and you never know what you might have stepped in. has the pandemic now made sounds kavi to more
8:26 am
common than of that coronaviruses. this question can't really be answered since we just don't have the data but i would say it's probably no at least at this point 7 perona viruses are currently known to infect humans the list includes sars and murmurs and then 4 strains that aren't deadly at all they only cause cold like symptoms most of us will get those last for at some time in our lives and many of us will get them repeatedly at the moment we've confirmed a couple of 1000000 covert 19 cases now even if 10 to 20 times that number of people have actually been infected and haven't been confirmed we're still talk. maybe 50000000 the hypothetical cases of prove it 19 worldwide but there are over 7000000000 people on the planet and and how many of us have colds at the moment a lot almost certainly many more than have or have had prove it 19.
