Using Game Theory to Analyze Risk to Privacy: An Initial Insight

Today, with the advancement of information technology, there is a growing risk to privacy as identity information is being used widely. This paper discusses some of the key issues related to the use of game theory in privacy risk analysis. Using game theory, risk analysis can be based on preferences or values of benefit which the subjects can provide rather than subjective probability. In addition, it can also be used in settings where no actuarial data is available. This may increase the quality and appropriateness of the overall risk analysis process. A simple privacy scenario between a user and an online bookstore is presented to provide an initial understanding of the concept.
