| Abstract(in English) | We propose a privacy protection method for use by service providers supplying users with services where user information requires privacy in the ubiquitous networking environments. The main feature is the use of an entropy value as a criteria for the evaluation of anonymity. This prevents loss of the convenience of services in the target environment. Objects in the ubiquitous environments will include more private information. This is because information gathered by sensors and so on will be added to static information such as sex and age. Furthermore the end-to-end communication assurance that are conventionally used become more complicated. In the new method, privacy information is managed in a database on a server. The novel idea behind the method is that a calculated by using this database decides whether or not the provider is given access to private information. The entropy value is independent of the number of people listed in the database, so the values are consistent over time. We implement the proposed method and evaluate it though simulations, thus confirming its anonymity feasibility. |
