Laws of Identity

When digital identity ceases to be a pain in the ass, we can thank Kim Cameron and his Seven Laws of Identity, which he wrote in 2004, formally published in early 2005, and gently explained and put to use until he died late last year. Today, seven of us will take turns explaining each of Kim’s laws at KuppingerCole‘s EIC conference in Berlin. We’ll only have a few minutes each, however, so I’d like to visit the subject in a bit more depth here.

To understand why these laws are so important and effective, it will help to know where Kim was coming from in the first place. It wasn’t just his work as the top architect for identity at Microsoft (to which he arrived when his company was acquired). Specifically, Kim was coming from two places. One was the physical world where we live and breathe, and identity is inherently personal. The other was the digital world where what we call identity is how we are known to databases. Kim believed the former should guide the latter, and that nothing like that had happened yet, but that we could and should work for it.

Kim’s The Laws of Identity paper alone is close to seven thousand words, and his IdentityBlog adds many thousands more. But his laws by themselves are short and sweet. Here they are, with additional commentary by me, in italics.

1. User Control and Consent

Technical identity systems must only reveal information identifying a user with the user’s consent.

Note that consent goes in the opposite direction from all the consent “agreements” websites and services want us to click on. This matches the way identity works in the natural world, where each of us not only chooses how we wish to be known, but usually with an understanding about how that information might be used.

2. Minimun Disclosure for a Constrained Use

The solution which discloses the least amount of identifying information and best limits its use is the most stable long term solution.

There is a reason we don’t walk down the street wearing name badges: because the world doesn’t need to know any more about us than we wish to disclose. Even when we pay with a credit card, the other party really doesn’t need (or want) to know the name on the card. It’s just not something they need to know.

3. Justifiable Parties

Digital identity systems must be designed so the disclosure of identifying information is limited to parties having a necessary and justifiable place in a given identity relationship.

If this law applied way back when Kim wrote it, we wouldn’t have the massive privacy losses that have become the norm, with unwanted tracking pretty much everywhere online—and increasingly offline as well. 

4. Directed Identity

A universal identity system must support both “omni-directional” identifiers for use by public entities and “unidirectional” identifiers for use by private entities, thus facilitating discovery while preventing unnecessary release of correlation handles.

All brands, meaning all names of public entities, are “omni-directional.” They are also what Kim calls “beacons” that have the opposite of something to hide about who they are. Individuals, however, are private first, and public only to the degrees they wish to be in different circumstances. Each of the first three laws are “unidirectional.”

5. Pluralism of Operators and Technologies

A universal identity system must channel and enable the inter-working of multiple identity technologies run by multiple identity providers.

This law expresses learnings from Microsoft’s failed experiment with Passport and a project called “Hailstorm.” The idea with both was for Microsoft to become the primary or sole online identity provider for everyone. Kim’s work at Microsoft was all about making the company one among many working in the same broad industry.

6. Human Integration

The universal identity metasystem must define the human user to be a component of the distributed system integrated through unambiguous human-machine communication mechanisms offering protection against identity attacks.

As Kim put it in his 2019 (and final) talk at EIC, we need to turn the Web “right side up,” meaning putting the individual at the top rather than the bottom, with each of us in charge of our lives online, in distributed homes of our own. That’s what will integrate all the systems we deal with. (Joe Andrieu first explained this in 2007, here.)

7. Consistent Experience Across Contexts

The unifying identity metasystem must guarantee its users a simple, consistent experience while enabling separation of contexts through multiple operators and technologies.

So identity isn’t just about corporate systems getting along with each other. It’s about giving each of us scale across all the entities we deal with. Because it’s our experience that will make identity work right, finally, online. 

I expect to add more as the conference goes on; but I want to get this much out there to start with.

By the way, the photo above is from the first and only meeting of the Identity Gang, at Esther Dyson’s PC Forum in 2005. The next meeting of the Gang was the first Internet Identity Workshop, aka IIW, later that year. We’ve had 34 more since then, all with hundreds of participants, all with great influence on the development of code, standards, and businesses in digital identity and adjacent fields. And all guided by Kim’s Laws.
