munk problem and his fellows andrew co-founders have been actively collecting data since 2013 today the firm employs more than 160 people and mainly analyzes data from the asian market they help authorities and companies to control their image there's been little criticism about how they process the data our job is not on the data but our job is on the life that is the father brand to understand it so in the end we help it to understand it. but data security specialist cost a normal is more critical he believes that the global trade in data is a multi-billion dollar business from which only a few players profit. google alone earns over $100000000000.00 a year with online ads. and of course not $100000000000.00 has to be recovered somehow through the products that are being advertised so a single company earns hundreds or thousands of dollars

a year from each internet user. then there are the data brokers who profit from collecting and analyzing this flood of data using special software we try to find out who's tracking user behavior the triangles here represent the trackers the circles the websites visited. even users who don't log in aren't surfing anonymously with every click the trackers network grows in this test there were close to 20 trackers for every web site visited. big data analysis helps link that information and produce a digital profile of the user. and. a profile like this describes a person and their fears their needs and possibly their financial situation allowing for advertising to be tailored to meet their budget that it describes as better than even our best friends could become. so companies might know me better

than my friends do even very sensitive data like that used by health apps is often passed on to data collectors without users knowledge the legal basis for this is sometimes highly questionable. massive amount of data is generated every day it comes from a variety of sources not just the internet. whether on facebook instagram or net flix every day we humans generate 2500000 terabytes of data but not all of it on the net visit a doctor in your sentence and diagnoses are stored in servers this data is often anonymous and passed on to market researchers when you found some of the collins location and contact details are scooped up and become part of big data brokers encyclopedia defines big data as a monster so large change so fast or so very that it can't be processed with standard software. exactly how much data counts as big is hard to say as it's not

stored to analyze centrally i see all of this estimate that in the next 6 years the global data speed will rise to 175 bytes per year one set of bite is equal to $1000000000.00 terabytes one trillion gigabytes one quadrillion megabytes in comparison a 3 minute m p 3 track is around 3 megabytes in size so once that's a point can store around 333 trillion songs processing such monsters of data isn't easy there are 3 aspects to consider. their stuff hardware aspect what hardware can handle it. second there's the software that processes the data directly. there's the algorithms which glean information and knowledge from the state are. becoming.

hardware software algorithms it's a big business. analyst using software platforms called frameworks they divide data between several high performance servers. where it can be processed simultaneously processing that data quickly is key. data artisans a burden based startup comes in they analyze very large amounts of data very fast using an open source platform called apache flink they help create it processes incoming data in real time and can simultaneously analyze data has already been stored stream processing is a big new thing so it's no surprise that chinese conglomerate alibaba snapped up dozens for an estimated $90000000.00 euros earlier this year that's great for the startup founders but is it good for society who are here legally and this poses a risk to the data could be compiled on unaligned in such

a way that for instance human behavior becomes more predictable and transparent. and that should end up limiting individual freedom to the media if i have as i mentioned i'm good friends felt honestly that i am pretty generous when it comes to my personal data if i look into a service and like it i'm willing to pay for it with my data but maybe the prize really is too high is trading your personal data for free apps or services a fair exchange all will big data turn into a surveillance nightmare what do you think join the discussion on facebook on the w dot com goodbye until next time.

the eco rebels of the himalayas. see come a state in northeastern india to switch entirely to sustainable agriculture. how did they pull it off. and what could german farmers learn from them. because look. this is

a very different line out we shouldn't team behind the team. it . seems just. to me. a forest area equivalent to a soccer futures is cleared every. hour consumerism is causing a radical depletion of firsts. for 25.

or has it. forests and money. tragic reality behind the exploitation. starts july 24th 2 double. sea come in the eastern himalayas a unique experiment is underway in this small indian state agriculture here is 100 percent organic synthetic pesticides and fertilizers are banned. we're not only taking everything from the environment but a real giving something back to the environment. in germany meanwhile organic farming remains a niche market why is it still not mainstream is sea come an example for other

countries to follow.
