Size doesn't matter: regulating "big data" in a "small data" world

Big data is everywhere. Once the preserve of innovators and technology entrepreneurs, big data analysis is now routinely used by a wide range of public and private sector organisations. It’s a tool for planning, resource management and gaining competitive advantage.

Either way, big data creates challenges for traditional data regulation regimes.
