Protecting User Privacy in WiFi Sharing Networks

Free registration required

Executive Summary

Wi-Fi sharing communities are an interesting option for mobile Internet access. Today, however, users need to give up privacy in exchange for connectivity: they are required to expose their identity in order to be granted access. This information can be used to track users and to generate usage and movement profiles. The authors identify the challenges of providing a maximum level of privacy and anonymity in a Wi-Fi community. From a discussion of privacy properties of existing architectures, they arrive at a privacy-aware Wi-Fi sharing design for fully anonymous usage - without sacrificing any participant's security or legal safety.
