Identifiers Enable Discrimination
Kim Cameron posted his Second Law of Identity
The Minimal Disclosure Law of Identity
The solution which discloses the least identifying information is the most stable, long-term solution.
“The thesis here is that the more identifying information is released, the more a solution invites abuse by rogue (and ultimately criminal) elements. We will return to a more rigorous discussion of these dynamics later in our conversation. For now, we will just point out that we are getting many reinforcing reports about the increasing professionalism and criminalization of identity attacks.”
This got me thinking that the basis of identity is to enable discrimination. I then realized that the negative, emotional response to universal IDs is a fear of unjustified or undesired discrimination through data correlation. Racism and sexism being the more evocative “isms”. We can “blame” the movie (or book for older people )* 1984 for surfacing this as a fear of the future.
Of course we all want positive discrimination per the Clue Train Manifesto and as Doc Searls promotes he wants in his relationships as a customer.
Tying this back to Kim’s Second Law, I agree with the law. Perhaps Kim may expand more on the basis for the law and how discrimination fits in.
When we were designing SXIP, we intuitively knew this law. A talk at the first DIDW demonstrated that in the digital world, we could provide much more granularity in the information we disclose than in the physical world. It is easy to have thousands of digital assertions about you, such as “I am over 19″, “I am over 21″, “I am under 65″. Each of these only discloses the amount of information I may need to disclose to conduct a transaction. In the Real World, when I show my driver’s license or passport, the entity receiving the information is obtaining more data then they likely need such as my name, address, date of birth: when all the need to know is that I am old enough to buy a bottle of wine. The issue (as Kim’s law points out) is that the additional information may be used maliciously. This increase in privacy that is possible in the virtual world is very compelling.
*Dave Kearns helpfully pointed out there was the book before the movie. “Doh” … I even read it in high school.
