There are things that we have already been talking about.
In a sense, they can be talked about in terms of technological changes and the new kinds of means of finding out about individuals for one purpose or another. There are things I mentioned in terms of the trends toward a greater use of biometrics, and sensors being embedded in buildings, streets, vehicles, and so on. A lot of it sounds like coming to terms with the technological changes that are already occurring. That seems to me to be crucial.
On the other hand, I've been trying to stress the ways in which the very idea of privacy has altered since the 1980s, when the act was originally conceived. It seems to me to be essential that we bear that in mind as well. This comes into, or is completely consistent with, what Lisa Austin is saying about the need for charter compliance here.
It seems to me that the notion of privacy was once conceived in a very atomistic and individual way, and it had to do with very specific harms that could be identified. In today's situation, we have to think about a much broader range of issues that have to do with democratic participation and human rights, so the very notion of privacy, it seems to me, needs to be expanded.
It's both things: it's coming to terms with the real technological changes—and again, big data is a huge issue here—on the one hand, and it's also understanding how the notion of privacy has itself evolved into a much more social and participatory matter than was thought of in the Privacy Act originally.
