Computer Assisted Consent for Personal Data Processing

The changes imposed by new information technologies, especially pervasive computing and the Internet, require a deep reflection on the fundamental values underlying privacy and the best way to achieve their protection. The explicit consent of the data subject, which is a cornerstone of most data protection regulations, is a typical example of requirement which is difficult to put into practice in the new world of "pervasive computing" where many data communications necessarily occur without the users' notice. In this paper, we study the legal implications of the use of "Privacy Agents" to make privacy right protection more effective. We consider successively three aspects of consent - its nature, its essential features (qualities and defects) and its formal requirements, and we draw the lessons of this legal analysis for the design of valid Privacy Agents. To conclude, we suggest an implementation of these requirements developed in PRIAM 1 , a multidisciplinary project involving lawyers and computer scientists.
