All that in just a second from the new business. Also on the program a major prisoner swap off the months of negotiations ukraine and its pro russian separatists exchanging captives in an effort to deescalate hostilities in the countrys east. And we also head to south africa to find out why a group of pensioners in johannesburg has picked the unlikeliest of sports to keep themselves from. Hello and welcome my name is Christopher Spring good to have you with us europe. In the german city of light to grapple with some of the tougher questions of all Digital Future how can we protect our personal data for instance how can we stop cyber criminals from targeting our mobile phones under the motto do something some fifteen thousand participants are attending the annual congress of the Chaos Computer Club. Normally this c. C. T. V. Cameras at the leipzig Conference Center record everything but right now theyre switched off one major theme at this years Chaos Computer Club congress is privacy including house state surveillance and spices dims endanger it. Those who want to be able to hack an entire population need to find a unique vulnerability on every single device but that doesnt mean that this point of access will only be exploited by authorities fighting crime. Computer club members have warned that such vulnerabilities leave users open to being spied on by criminals or even foreign governments but Digital Rights groups also warn users that theyre handing over too much personal information voluntarily including to big businesses like facebook and google. Isnt that inventive and this data is used to build the most accurate user profile possible this is then used for business and sometimes even to manipulate us its not always for profit but very very often it is the Chaos Computer Club says its expecting about fifteen thousand attendees from all over the world at the forty congress and with speakers covering issues from it security to Artificial Intelligence there will be plenty for hackers and computer experts to talk about. And joining me now in the studio for more on the Chaos Computer Congress and why. Youve been spending time at the congress on the first day the event held on of the slogan do something what exactly do europes hackers want to do something about the fact that there is a lack of awareness about whats going on a lot of people feel you know they just they about they have the gadgets they have the devices they use and the security and their security and its basically a throwback to nine hundred eighty one when the computer was actually found so theres as much stenger now if not even more than then thats what a lot of them are saying and people need to take note and start doing something about it what was the danger back then in one tonight you know or i mean were looking at a time. When at the end of the seventys there were terrorists in germany left like left super left wing terrorists and they had sort of done a couple of things that had scared a lot of people and so its the cold war as well those people being watched and monitored so the same is happening now only now were talking about businesses organizations also having my data so essentially the techies shall we call them at the Computer Club saying we all have to do something Computer Security is an issue for all of us its a wake up call if you will exactly its the wake of coal one hundred eighty one its just as bad today if not worse thats what they say basically ok and you know what one of the toughest challenges that theyre talking about at this count all the main challenge or one of the toughest challenges is what is called the internet of things now these are devices that are connected to the internet so it could be or smart watch it could be most of us have a smart watch smart phone rather and also were talking about even things like your fridge or your stove so you know. Basic device that people use every day are sending data over the net and all of this without security because companies are being forced to launch products that are not secure enough or not protecting our data enough fast in the market to make money and theres not enough incentive as well for companies to make data secure it just because of course the punishments are not you know they dont hurt enough on their revenue at least and and just briefly hit even the electric charging stations for electric carts can be manipulated can be hacked exactly that was the big news here in germany the cards they used to pay at public charging stations can be easily copied because theyre not encrypted and thats a major issue that we have so thats something that consumers were unaware of but because of the congress this year thats something thats become big news ok so governments have to do something about that so but so do all of us exactly ok chip on how many thanks for all that. Turning to ukraine the Ukrainian Government and its separatist rebels have exchanged hundreds of prisoners in one of the largest such hostilities broke out in the countrys east three years ago the deal followed months of negotiation its part of the mint peace accord signed in turn two fifteen and the hope now is that the exchange will for the deescalate a conflict that so far claimed over ten thousand lives.
