Privacy protected routing in delay tolerant networks

As illustrated in Chap. 3, the most recent research on human associated DTNs uses social information to improve performance, thus demonstrating social characteristics are important factors to improve performance. However, little has been done concerning the privacy issue in DTNs. With increasing use of social information, more and more social characteristics related data is disclosed without permission. Due to the privacy issue, most trace providers do not want to release data with meaningful social information, that may be used to identify the data entered especially for a large dataset. For example, AOL published a query logs but quickly removed it due to the re-identification issues addressed in [1]. Consequently, researchers are trying to find ways to anonymize personal information while maintaining network functioning.
