social networks is unsatisfactory at best the facebook cambridge analytical scandal has brought the issue back to the fore it's time users reclaimed control of their data. every move we make online leaves a data trail social networks apps and information brokers collect those data and trade them. according to estimates data trading generates around one hundred twenty billion euros a year worldwide and that number is rising the business model behind it to make users transparent without their realizing it. and this is one of the biggest risks with with lack of privacy on the internet is that things happen without us knowing we are denied credit or refused we're not shortlisted for a job or something like that is happening without us knowing because somehow information about us has been garces to and then use out of context. but what do.

to do facebook and google collect it's possible to download a copy of your personal information although if you have an account with google that data alone could be several gigabytes. google saves all of our searches. and knows things like when we need to have our phone repaired. it keeps track of places we spend time in and follows us as we move through city. your facebook data includes the private messages you sent right down to the post. both google and facebook can share their users data with third party. users can't control what happens with their data once it's been shared what's more interesting is how that data used and used to target and attempt to influence and manipulate not just the people who have the data access but almost everybody i think it is true that in some ways they control so much that it's life like a dictatorship but a kind of hidden dictatorship is working with soft power rather than rather than

hard power with influence and nudge rather than coercion and unforced. there are ways of escaping some of this influence data protection activists recommends checking your privacy settings regularly and turning off apps that facebook shares data with but. if that isn't enough to survive has another piece of advice. i personally love to play with the data that's being collected about me because you know like you are using these technologies you are generating there is there are plugins there are things that you can do that can send noise into the data that's being collected about. this so-called digital data noise creates meaningless tracks online users become harder to understand in the us harder to target or manipulate. the app data while it takes a different approach users can connect the app to online accounts like facebook the app pulls user data from those platforms so that a user can anon. mostly sell their own data. the first thing that i think is

important is that we get this paradigm shift from just giving companies our data to you know regaining control and ownership of our data obviously those other platforms still have it because as long as you stay on facebook you allow them to use it paid out but if you all saw have all the data feed into our app you can decide ok what what do you want to do with it so you do learn something from your data. how much you could earn is still unclear but it is a step towards self seventeen although for true data autonomy there also needs to be transparency regarding algorithms. the way that the google search algorithm works the way that facebook's news curation algorithms work they're considered trade secret so no one has the right to look at them they have the right to keep secret and so now that means that we have no autonomy and that in the talk and the idea of algorithmic or did it where we go in and look at what the algorithms that

do it we have or thirty's to do so is i think one of the most important things for us to establish in terms of terms of data retirement. impossible to stop leaving dated trails but we need to be aware of how our data are used. shifts as our data belong to us. and now appears in coach internet users are being influenced without their knowledge by social media algorithms. users will only see content that is relevant to them that's what social networks promise. so what determines which content is relevant the social media algorithms that work with user data. the most important data on likes which topics does if you like this he or she prefer videos or takes to. which post so popular across the network. algorithms use

these data to select a post for an individual's feet conflicting opinions or too many details are withheld from the user. according to experts an algorithm needs around three hundred lines to really know a user. algorithms can also be private details users haven't shared on the network like whether their parents are divorced. using data benefit something else to. advertising which is a profitable business for social networks. they are paid posts to the feet selected according to. users can turn this pre-selection. shown in chronological order but that preference isn't safe so the next time they log on they will again see posts selected by an algorithm using that data.

and no social network or commercial platform what's the true purpose of facebook the us company makes a lot of money thanks to its detailed user profiles something that data advocates and others are protesting against. facebook's main mission according to founder mark zuckerberg is to connect people online but the company makes most of its money selling ads in two thousand and seventeen around ninety eight percent of its revenue over thirty billion euros came from advertising. whether it's for a political campaign or for a commercial company facebook can identify the correct target group and send them specifically tailored content. interaction alone reveals a lot about any given user such as their ethnic heritage gender sexual orientation and political or religious views predictions made using interaction are correct

eighty percent of the time and feed into the personality profiles with up to fifty two thousand variables that facebook uses in its economic model. in this new body all we need to talk. the impact of the new economic system users across germany are being made transparent but they're sort of classified targeted by companies that are not aware that this is happening about. facebook also collaborates with other data collectors the largest data brokers have more than five billion personality profiles meaning that every person with internet access has been recorded in some form. data brokers analyzed browsing behavior and user searches on line in addition there is the data from retail groups this information is added to postal addresses e-mail addresses and location data almost anyone with a smartphone can be analyzed. data brokers make individuals information available to facebook so that the company can improve its users profiles in turn facebook

gives data brokers access to some of its data. broker market is huge specially in the u.s. it's also due to the data protection laws just like the ones we have in europe exist in the us means the mining and trading data is basically fair game. wouldn't. change as between a company like facebook and other data brokers takes place in a figurative black box. and black book starts with. data brokers servers are often located in the us beyond the jurisdiction of european however the service also contain data belonging to european users. considering our views and opinions can manage users are really should know much more about. so you're coming from. russia will do some cities could ultimately influence them.

facebook says it wants to provide more data protection but would they give up the lucrative day to trade. shifts as more transparency please. handle short and sweet it's the ship snapshot. online data collectors use trackers to analyze users' behavior among other purposes the information gathered is then used for targeted advertising those who do not want to be tracked around the web there's the previously badger free browser extension. the extension keeps your browsing behavior from being tracked unlike other blocking tools previously badgered doesn't happen list of common trackers instead the add on learns what to block does so once it has identified the same track on three different websites. alternatively users can configure the add on themselves. the browser extension was created by the u.s.
