(1992/12–2000/3) problem and to design and construct a practical protection mechanism so that information

can be shared e ciently and personal privacy can be protected at the same time. Over the
past few years, we developed a prototype system, CellSecu, to safeguard personal privacy.
The system will check if datasets to be released leak too much personal information. We

discovered an appropriate logic model for the problem and quanti ed the privacy leakage with information theory and economic
models. Secure Multiparty Protocol can be applied to allow some important information to be computed while the data owners do not
have to reveal their data. Although there are beautiful theoretical solutions, they are not suitable for problems involving large datasets.

We try to quantify the information leakage in this setting with an information theoretical framework, so that the trade-o between the
computational resources needed and the level of privacy protection achieved becomes appropriate.
