Business agrees with governments — the more personal information they gather about us, the more “helpful” they can be. Should we give in to this “harmless” new science of benign surveillance, asks Steven Poole in The New Statesman.

“Through Big Data analysis, the “cloud” comes to know an awful lot about us. Simply analysing a person’s Facebook “likes” can identify a person’s sexual orientation or history of drug use. Even just searching for things and filling out online surveys can lead to personal information about you being bought and sold by big marketing analytics companies. When the Big Data is data about you, privacy becomes a faint memory. And this is true not just on the web. The Data Privacy Lab at Harvard University recently managed to identify 40 per cent of individuals who had taken part (again, supposedly anonymously) in a large-scale DNA study, the Personal Genome Project.”
