A collection of privacy design patterns

The growth in computing power has enabled the storage and analysis of large volumes of data. Monitoring the Internet access profiles of millions of users has become feasible and also economically lucrative. The interesting thing here is that it is not only the crooks who are interested in privacy intrusion, but government agencies also have vested interest in profiling the population mass. This paper describes 4 design patterns that can aide the decision making process for the designers of privacy protecting systems. These design patterns are applicable to the design of anonymity systems for various types of online communication, online data sharing, location monitoring, voting and electronic cash management.
