Data Privacy in the Big Data Era

The technology and promise of big data, together with algorithms and artificial intelligence, have revolutionised our society. They bring not only new opportunities, but also risks, to the way we live, work and make decisions. In private business and in the public sector, these evolving technologies have been used for the purposes of profiling, monitoring, predictive analysis and risk calculation. At the same time, we, as individuals, have become digitised data selves. More worrying, the proxy data self can dictate the life of the corporeal self, as we have seen in the practice of financial credit scoring or social credit scoring.

This lecture explores data privacy protection for the digitized persona, focusing on the challenges brought by profiling. The speaker argues that we should move from a pure opt-in consent regime to an accountability model for big data analytics.
