Google Chrome Introduces Innovative “IP Protection” to Enhance User Privacy

Google is set to test a new feature in Chrome named “IP Protection,” aimed at bolstering user privacy. This feature, which masks users’ IP addresses using proxy servers, is Google’s response to the increasing misuse of IP addresses for covert tracking. IP addresses are crucial for web functionalities like traffic routing and fraud prevention, but they also enable the creation of persistent user profiles through cross-website tracking. The “IP Protection” feature will make users’ IP addresses invisible to certain domains by routing third-party traffic through proxies.

Initially, “IP Protection” will be an opt-in feature, allowing users to control their privacy settings. Google plans to introduce the feature in stages, starting with proxying requests to its own domains. This phase, known as “Phase 0,” will be limited to users logged into Chrome with US-based IPs. A Google-operated authentication server will issue access tokens to the proxy, ensuring controlled usage.

Future developments include a 2-hop proxy system for enhanced privacy, where neither proxy can view the client’s IP address and the destination. This system aims to balance privacy with the functionality of GeoIP services, assigning coarse location IP addresses to proxy connections. Google intends to test the feature across Chrome 119 to Chrome 225 versions, beginning with its platforms like Gmail and AdServices.

However, there are cybersecurity concerns. Proxied traffic through Google’s servers may hinder security and fraud protection services, and a compromised Google proxy server could expose user traffic. To mitigate risks, Google considers authentication requirements for proxy use and rate-limiting to prevent DDoS attacks.
