In this session, you learnt a lot about database security. We will focus three topics for this conference: (1) Inference in ordinary databases or statistical databases, (2) database privacy (through encryption),and (3) cloud security. Please pick one of these three topics and explain in your own words what the problem or issue is, how the issue is being addressed and some of the concerns with the solutions being proposed. Your post can be a new one or an enhancement to someone else's post(s). Please avoid duplication.
