For more details, let me refer you to my submission.
Generally speaking, I would say that the principles can be clear and unambiguous, but not the rules. I agree with many of the speakers who speak favourably of the importance of having principle‑based privacy laws, such as the principle of corporate social responsibility. That principle needs to be defined broadly. Since technology is constantly and exponentially changing, I think it would be wishful thinking to believe that it is possible to have very precise, clear and permanent rules.
I agree that we must aim at the principle of transposing our values into our legislation. You are clearly asking the right question in asking how to do this in practice. There is a need for general principles, defined flexibly enough to accommodate the evolution of technology, but not so specific as to be detrimental to it, with the aim of both protecting privacy and allowing the use of data for the benefit of society.
