Furthermore, the pace of technical change is ahead of the pace at which regulators can respond.

The cloud adds to an already fast moving industry. The total amount of electronic information held around the world is thought to double every 18 months. More data is ever being held in digital form by third parties and the risk of unapproved or malicious uses continues to increase. People are showing real inconsistency in their behaviour, demonstrating genuine concerns over data being held about them on one hand, but at the same
