In this paper, we adress the problem of user privacy for Internet Services that people use to publish private data. While many typical operations such as generalization and omission of detail have been discussed before, the contribution of the paper is to present simple yet powerful rules for enhancing privacy. We propose a new approach to map sensitive data to less sensitive ones using relevance constraints to preserve their utility. Several frequently encountered service usage scenarios motivate the presented rules.
