Joan Feigenbaum of the Yale Computer Science Department has an article, “Accountability as a Driver of Innovative Privacy Solutions,” available online.
The abstract:
The standard technical approach to privacy in particular and computer security in general is preventive: Before someone can access confidential data or take any other action that implicates privacy or security, he should be required to prove that he is authorized to do so. As the scale and complexity of online activity has grown, it has become increasingly apparent that the preventive approach is inadequate. It is our thesis that a paradigm shift to accountability, rather than prevention, as an organizing principle for privacy in online interaction could spark much needed innovation.
