Title: Privacy and Statistical Data

I will give a quick overview of the following:

(1) the need for data collectors/disseminators to keep data provided by individuals for statistical purposes hidden from prying eyes, and the concept of statistical disclosure;
(2) typology of statistical data products released by government statistical agencies and similar organizations and their vulnerability to disclosure;
(3) intruder behavior;
(4) defining disclosure quantitatively; and,
(5) methods for disclosure limitation and their weaknesses.

I will suggest (or at least initiate a discussion towards) problems that appear amenable to cryptographic solutions or analysis.
