On-line privacy controls have been the subject of much research but relatively little has been done to explore the different interactions that service users would like to have about on-line privacy. This talk presents research in this area and outlines some of the common problems that service users have with making sense of the privacy controls that are offered to them. It also contains proposals as to how on-line service design might be adjusted to resolve these issues. This research is the result of the Visualisation and Other Methods of Expression (VOME) research project which explores why service users interact with on-line privacy controls in the way that they do. The project's primary goal is to develop interaction tools to help service users make better sense of their on-line privacy protection options. VOME is funded by the Technology Strategy Board, EPSRC and ESRC.
