The lecture โData for Dummiesโ given by technology philosopher Tsjalling Swierstra begins fifteen minutes later this Thursday evening. The hall in retirement home Eerdbrand where the lecture on the (im)possibilities of big data would take place, actually still is occupied. The billiards tournament is not over yet. Another, much smaller, parlor offers a solution.
The lecture is organized by Het Nieuwe Instituut, which is hired by the municipality to help Eindhoven become a smart society through the โStae of Eindhovenโ program. Program Leader Linda Vlassenrood explains why the venue is at a nursing home: โWe could have done this in the Van Abbemuseum, but we really want it to be in the midst of society. Thatโs why weโre here.โ
Under the title โThe State of Eindhovenโ E52 brings a series of articles about the effort the city is taking to become a smart society, and about the connections that are needed between big data and real people. Read the whole series here.
A total of 20 concerned citizens have managed to find their way to the retirement home. A photographer is walking around and shoots his snapshots. There are still some empty seats. Having moved to a smaller room wasnโt so bad after all. The possibilities and pitfalls of big data are, apparently, only of interest to a small group of local residents. Even when just about everyone has to deal with big data in some way.
Swierstra puts away the microphone, he doesnโt need one here. โWorldwide, there are 2,3 billion gigabytes of digital information available on a daily basis,โ the professor begins his argument. โSensors in public spaces such as cameras collect a lot of data. Data that can be used to better regulate things in the city. For example, traffic or public safety.โ
Data are not only mined in the public domain. Social media, websites and all sorts of phone applications continuously collect data about people. โCombining all these data enables pattern recognitionโ, Swierstra says. โTherefore, anonymous data is actually an illusion.โ
A company or government agency may anonymise data, but combined with other data โde-anononymisingโ is also possible. โThese data are therefore worth a lot of money.โ In fact, those who use a free service like Google pay with their data.
โCompanies like Google and Apple are currently best in analysing all the data,โ Swierstra continues. โEven universities and hospitals have their data analysed by them.โ
A person in the audience responds: โThe biggest companies in the world take possession of our data and the politicians do nothing about it.โ The photographer stands up, gets his camera in position. โPlease donโt take any pictures. I havenโt given permission and we are in a private roomโ, says the elderly, gray-haired man.
โIโm nowhere to be found on the internet and want to keep it that way.โ
He wants to remain anonymous. โIโm nowhere to be found on the internet and want to keep it that way. My data are mine and nobody elseโs.โ The man tells that he bought his first PC in the early 1980โs. He has closely monitored all the technical progress since then. Now he is retired and has even more time to keep track of all developments. โThe government can do little. You simply cannot forbid people to share their data.โ
The observation of the old man hits to the heart of Swierstraโs lecture: โDigital information is like a picture of a regretful activity during oneโs younger years: it will never go away.โ
And thereโs a lot more to think of when you consider what one can do with data. โWhat if you canโt buy certain products because data suggest that you canโt handle money well? Or what if police would preventively go to certain neighbourhoods because the data suggest that the risk of violence there is greater than elsewhere? Could that give somebody a stigma for no reason or even get someone arrested before anything has happened?โ Not to mention data being hacked by intruders.
โThe reality is we do not know where it is going with big data.โ
Swierstraโs conclusions can hardly be ignored: โThe reality is we do not know where it is going with big data.โ Compare it to the Internet. Everyone thought the web would have a democratising effect. A sort of digital town square for debate. โBut now everyone runs away from Twitter because it has become such a sewer.โ
That uncertainty, however, is always present in innovation. Whether this is sufficient reason to fear the rise of big data is the question. One thing is absolutely clear after the lecture: think twice before you share your data.
