Who Controls Identity on the Web?
The race to own your virtual identity is on. In announcements made just days apart at the end of April, Facebook and the Mozilla Foundation launched parallel efforts to extend the way users are identified and connected on the Web.
The two approaches are fundamentally different. Facebook’s Open Graph Protocol uses the oAuth standard, which lets a website identify a user via a third-party site without exchanging sensitive information. Facebook–whose 400 million active users make it the world’s largest social network in the world–stands to benefit as other sites come to rely on the information it holds about users and their social connections.
The approach taken by the Mozilla Foundation, which makes the Firefox browser, comes in the form of a suite of browser extensions. One of the extensions, called Account Manager, can replace all of a user’s online passwords with secure, computer-generated strings that are encrypted and protected with a single master password. Mozilla’s identity extensions can interact with other identity standards, including OpenGraph, oAuth, and OpenID, a standard that allows any website or Web service provider to host a social network-style profile of a user. The goal of the Mozilla Foundation’s efforts is to establish a set of open standards and protocols that could be implemented in any browser or website.
As much as possible, identity would be moved out of the webpage itself and into the “chrome” of the browser–the parts around of the webpage. Logging in and out of sites would be accomplished through buttons at the top of the browser that would activate secure protocols–rendering the process of creating and memorizing usernames and passwords obsolete.
“Every user of the Internet today is expected to describe themselves to every site they go to,” says Mike Hanson, principal engineer at Mozilla Labs. Inevitably, Hanson says, this leads to confusion and security holes, such as passwords that are identical across multiple sites.
The solution, according to Hanson, is to let the browser itself manage user identity. Weave Sync, another Mozilla extension, is designed to enable that vision. It stores encrypted versions of a growing list of data on a Mozilla-hosted server (or any user-specified server), including a person’s history, preferences, bookmarks, and even open tabs, which can be synced across two or more browsers. This allows users to have the same browser workspace on any device that supports Firefox or its mobile equivalent, Fennec. There’s even a prototype for the iPhone, built on top of Apple’s Safari browser.
Last fall Mozilla Labs also commissioned Chris Messina, at the time a researcher in residence at Mozilla Labs, to design a Web browser that would manage the other half of online identity–a user’s social graph. In Messina’s mock-ups, a user can interact with people on the Web in ways that go beyond what OpenID or Facebook’s OpenGraph currently offer. “The idea of a social browser is important to me because it’s the single point of integration for all websites,” says Messina. “It’s the one thing that knows who you are across all social experiences.”
Messina’s designs envision a browser that lets users “follow” other users by viewing all of their relevant information streams–Facebook, Twitter, Flickr, etc.–collected into a single browser tab stamped with that user’s profile picture. A similar interface could also be used to control exactly what personal information other people and websites have access to. This could allow, for instance, a user to change her shipping address across any number of sites at once, or to control which version of their identity a particular groups of friends can access. “I’m not interested in the [Mark] Zuckerberg approach, where privacy doesn’t exist anymore,” says Messina, referring to the CEO of Facebook.
Both Facebook and the Mozilla Foundation will face challenges in pushing their own vision of online identity. John Mitchell, a professor of computer science at Stanford, says the most significant barrier will be the adoption of suitable protocols. Before such protocols can be standardized and rolled into, for instance, the next version of HTML, Web developers are going to have to be willing to experiment.
“What I’ve seen from a lot of companies is an attempt to guess the end solution and build that only,” says Mitchell. “It would be better if, instead, we had an open architecture where people could try many different approaches.”
If the new Mozilla software and Messina’s designs are sufficiently popular with users and developers (not to mention the influencers who sit on the boards of standards committees like the World Wide Web Consortium), then the foundation’s technology could find its way into the regular release of Firefox and perhaps, ultimately, into other browsers.
To Messina, just drawing up the blueprints for such technology was an important first step. “We’re further away from the death of the password than I’d like to be, but it’s a nice goal to aim for,” he says.
