Google Chrome to soon get a new ‘IP protection’ feature: Here’s what it does (indianexpress.com)

Google will soon start testing a new ‘IP protection’ feature for Chrome users, offering them greater control over their privacy. The tech giant the upcoming feature prevents websites from tracking users by hiding their IP address using proxy servers owned by Google.

To give you a quick recap, IP address is a unique numerical identifier that can be used to track a user’s geographical location and is used by advertisers to track a user’s browsing habits, see which websites they visit and provide personalized ads.

According to Google, the IP protection feature will be rolled out in multiple stages, with Phase 0 redirecting domains owned by Google (like Gmail) to a single proxy server. The company says the first phase will allow them to test its infrastructure and only a handful of users residing in the US will be enrolled.

Google also said that the upcoming IP protection feature will be available for users who have logged in to Chrome. To prevent misuse the tech giant will be implementing an authentication server that will set a quota for every user.

In the following phases, Google will start using a 2-hop proxy system, which essentially redirects a website’s request to a Google server that will again be redirected to an external CDN like Cloudflare.

While the IP protection feature might enhance user privacy, the tech giant has clarified that it is not a foolproof system. If a hacker is able to gain access to Google’s proxy server, they will be able to analyse all traffic passing through the network and even redirect users to malicious websites.

Since most of Google’s revenue comes from tracking users across the internet and offering them personalized ads, it will be interesting to see how the company strikes a balance between user privacy and revenue generation.

Isn't it obvious? Google own's the proxies. And judging by the look of this, they are going to act as a a Man In The Middle for HTTPS, so they will be actually able to see everyone's plain text connections. This is not a privacy feature, but a privacy nightmare. Like everything else on Chrome, tbh.

Edit: I don't know if they will be breaking HTTPS or no, since I didn't see the details of how this works. But even if they don't see your plain text traffic, they are logging your every request, which is scary.

You can't MITM HTTPS with a VPN unless the browser accepts an insecure certificate. And that can't be done without being detected; and the security community would raise seven shades of hell.

Google has actually helped build the infrastructure that (in a public, provable way that Google can't subvert) makes it impossible to get away with MITM in this manner. It's called Certificate Transparency.

Put another way: Google wants other big companies and governments to use Chrome and Android. If Google started MITMing traffic like you suggest, no corporation or government would ever touch their products again. So they've built infra that lets them prove they don't.

They could use this to get more accurate figures about the popularity of different sites or services by IP and port. But they don't need to; they have search.

Yes, but the browser is Chrome and this is a feature built into Chrome.

I tend to agree with the trust argument. Google wants people to rely on Web technology and Google products and allowing MITM - or failing to prevent - goes against Google's interest.

I don't buy the technical argument at all. Google could terminate the TLS connection at the proxy and communicate with the browser on a proprietary encrypted channel. Chrome could easily show a green padlock item and certificate details as seen by the proxy. The whole thing could be open source and transparent. A minority of users will disable the feature; many will accept it. Corporates can be bought by allowing to opt out for 'sensitive' servers.

They could just rewrite Chrome to send all your passwords in clear text to Mountain View too ... but not without security people noticing. That's my point. The behavior of browsers is not secret.
