A Flexible In-Network IP Anonymization Service
User privacy on the Internet has been an increasing concern in recent years. With the proliferation and sophistication of information services, data mining, and search engines, a simple network address may be used to reveal a great deal of information about a user, including location, identity, and behavior. Existing approaches to privacy, however, make unacceptable tradeoffs between performance and anonymity. For example, Tor attempts to provide strong anonymity by withholding trust from third-party relays. The authors believe an acceptable level of privacy can be provided to most users, with noticeably lower latency and throughput impact, by working with the network provider.
