Privacy-Preserving Network Forensics
Much of the Internet's success can be attributed to its minimalist architecture. However, the related architectural freedoms also represent ripe vulnerabilities for adversaries trying to exploit the network to their own ends. Chief among them is the lack of accountability for user actions. Without a plausible threat of accountability, the normal social processes that disincentivize criminal behavior cannot function. The authors suggest modifying the Internet architecture to proactively enable network forensics while preserving the privacy of network participants under normal circumstances.
