The issue of the protection of privacy of people participating in randomized response techniques has been given a lot of attention in recent years. Various (mathematical) measures of privacy protection have been devised and proposed which have been used so far, mainly to compare one randomized response technique with another. Little attention is given to the problem of respondent's perception of privacy protection. The respondents' decision to participate in a randomized response survey is not based on what mathematics say, but rather on what their perception of privacy protection is. In this talk we will focus on the issue of privacy protection from the participants' point of view.
Keywords: Randomized response; Protection of privacy; Respondents' perception of privacy protection
