Privacy-Enhancing Technologies (PETs) have been an enormous disappointment. Even where legal and organisational safeguards have worked effectively, technological inadequacies have undermined the three-component regulatory framework.This presentation identifies PETs' multiple failures, across the many areas of conception, requirements elicitation, architecture, design, dissemination, understandability, adoption and use. However, the insights into these failures are now leading towards a new round of products and services. PETs 2.0 promise to at last achieve the necessary breakthrough into the mainstream. A test-case is considered – the expression and enforcement of consents and denials – in order to apply the insights in a specific area of need.
