More information for better utility; less information for better privacy. The contradiction is everywhere in contemporary IT: doctors need accurate information for diagnosis, but insurance companies' access should be limited; on-line retailers use your postcode to present interesting products, but they also deduce from it how much you will pay. One way to manage this contradiction is to tolerate "small" information flows providing the risks involved can be accurately gauged. This project will build on recent advances in information measuring to develop new techniques for measuring the extent to which computer systems can defend against threats to privacy. Success in this project will lead to completely novel methods for security analysis of on-line applications where privacy is a critical issue.

更多的信息是为了更好的实用性；更少的信息是为了更好的隐私。在当代信息技术中，矛盾无处不在：医生需要准确的诊断信息，但保险公司的访问权限应该受到限制；在线零售商使用你的邮政编码来展示有趣的产品，但他们也会从中推断你将支付多少钱。管理这一矛盾的一种方法是容忍“少量”信息流，前提是所涉及的风险可以准确衡量。该项目将以信息测量方面的最新进展为基础，开发新的技术来测量计算机系统能够防御对隐私的威胁的程度。该项目的成功将为隐私是一个关键问题的在线应用程序的安全分析带来全新的方法。
