  One of the major views of privacy associates privacy with the control over
information. This gives rise to the question how controllable privacy actually
is. In this paper, we adapt certain formal methods of control theory and
investigate the implications of a control theoretic analysis of privacy. We
look at how control and feedback mechanisms have been studied in the privacy
literature. Relying on the control theoretic framework, we develop a simplistic
conceptual control model of privacy, formulate privacy controllability issues
and suggest directions for possible research.
