a privacy preserving proxy built on Internet standards
If you’re running a privacy-oriented application or service on the Internet, your options to provably protect users’ privacy are limited. You can minimize logs and data collection but even then, at a network level, every HTTP request needs to come from somewhere. Information generated by HTTP requests, like users’ IP addresses and TLS fingerprints, can be sensitive especially when combined with application data.To get more news about https://www.pyproxy.com/ proxy ip, you can visit pyproxy.com official website.
Meaningful improvements to your users’ privacy require a change in how HTTP requests are sent from client devices to the server that runs your application logic. This was the motivation for Privacy Gateway: a service that relays encrypted HTTP requests and responses between a client and application server. With Privacy Gateway, Cloudflare knows where the request is coming from, but not what it contains, and applications can see what the request contains, but not where it comes from. Neither Cloudflare nor the application server has the full picture, improving end-user privacy.
We recently deployed Privacy Gateway for Flo Health Inc., a leading female health app, for the launch of their Anonymous Mode. With Privacy Gateway in place, all request data for Anonymous Mode users is encrypted between the app user and Flo, which prevents Flo from seeing the IP addresses of those users and Cloudflare from seeing the contents of that request data.
How does it work?
The main innovation in the Oblivious HTTP standard – beyond a basic proxy service – is that these messages are encrypted to the application’s server, such that Privacy Gateway learns nothing of the application data beyond the source and destination of each message.
If you were to imagine request data as the contents of the envelope (a letter) and the IP address and request metadata as the address on the outside, with Privacy Gateway, Cloudflare is able to see the envelope’s address and safely forward it to its destination without being able to see what’s inside.
How Privacy Gateway improves end-user privacy
Request privacy means that the application server does not learn information that would otherwise be revealed by an HTTP request, such as IP address, geolocation, TLS and HTTPS fingerprints, and so on. Because Privacy Gateway uses a separate HTTPS connection between itself and the application server, all of this per-request information revealed to the application server represents that of Privacy Gateway, not of the client. However, developers need to take care to not send personally identifying information in the contents of requests. If the request, once decapsulated, includes information like users’ email, phone number, or credit card info, for example, Privacy Gateway will not meaningfully improve privacy.
Client privacy is a stronger notion. Because Cloudflare and the application server are not colluding to share individual user’s data, from the server’s perspective, each individual transaction came from some unknown client behind Privacy Gateway. In other words, a properly configured Privacy Gateway deployment means that applications cannot link any two requests to the same client. In particular, with Privacy Gateway, privacy loves company. If there is only one end-user making use of Privacy Gateway, then it only provides request privacy (since the client IP address remains hidden from the Gateway). It would not provide client privacy, since the server would know that each request corresponds to the same, single client. Client privacy requires that there be many users of the system, so the application server cannot make this determination.
