Flexible and dynamic consent-capturing

Abstract

Data usage is of great concern for a user owning the data. Users want assurance that their personal data will be fairly used for the purposes for which they have provided their consent. Moreover, they should be able to withdraw their consent once they want. Actually, consent is captured as a matter of legal record that can be used as legal evidence. It restricts the use and dissemination of information. The separation of consent capturing from the access control enforcement mechanism may help a user to autonomously define the consent evaluation functionality, necessary for the automation of consent decision. In this paper, we present a solution that addresses how to capture, store, evaluate and withdraw consent. The proposed solution preserves integrity of consent, essential to provide a digital evidence for legal proceedings. Furthermore, it accommodates emergency situations when users cannot provide their consent. © 2012 Springer-Verlag.
