that. big data has already allowed berlin's charity hospital to identify individual therapies for some 30 cancer patients. treating illnesses with the help of big data that's real progress and it shows that they are and humans can work together for the benefit of mankind. another thing that big data has done is make human behavior more predictable that's especially interesting for companies who want to target us online with personalized advertising that can still be hit or miss just because of research diving expeditions doesn't mean i want to buy a wetsuit right away but data analyst paul monk from from thailand are working on ways to optimize targeting when you play when you like when you stop to see you've already been audited there couldn't go to whatever. we are the technology to help the brand to know how to talk the right way to the right consummate with

information. from 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 our job on the life that is father brand to understand it so in the end we help it to understand it. but data security specialist cash to 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 web sites 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. a profile like this describes a person in their fears their needs and possibly their financial situation allowing for advertising to be tailored to meet their budget what it describes as better than even our best friends could one become. so companies might know me better than

my friends do even very sensitive data like that used by health abs as 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 the doctor in your sentence and diagnoses are stored in servers this data is often anonymous the person to market researchers when you phone some of the comments location and contact details are scooped up and become part of big data. brokers encyclopedia defines big data as a monster so large changes so fast are so varied that they can't be processed with

standard software. exactly how much data it counts as big is hard to say as it's not stored to analyze centrally i see analysts estimate that in the next 6 years the global data sphere will rise to 175 bytes per year one set of buy does equal to $1000000000.00 terabytes one trillion gigabytes $100.00 megabytes in comparison a 3 minute m p 3 track is around 3 megabytes in size so one set up i can store around 333 trillion songs processing such masses of data isn't easy there are 3 aspects to consider. there is the hardware aspect what hardware can handle it. second there is the software the process is the data directly. there's the algorithms which glean information and knowledge from this data. coming

. hardware software algorithms it's a big business. big data is analyzed 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 that's where 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 complement alibaba snapped up their business for an estimated 90000000 euros earlier this year that's great for the start of founders but is it good for society who are here legally and this

poses a risk to the data could be compiled on unaligned to such a way that for instance human behavior becomes more predictable and transparent. and that could end up limiting individual freedom if i had as i mentioned i suppose honestly i'm 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 or 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.
