Sometimes we want to do prove more interesting things with a digital credential. For example, imagine that I want to join a cryptocurrency exchange that needs more complicated assurances about my identity. For example: it might require that I’m a US resident, but not a resident of New York State (which has its own regulations.) The site might also demand that I’m over the age of 25. (I am literally making these requirements up as I go.) I could satisfy the website on all these fronts using the digitally-signed driver’s license issued by my state’s DMV. This is a real thing! It consists of a signed and structured document full of all sorts of useful information: my home address, state of issue, eye color, birthplace, height, weight, hair color and gender. In this world, the non-anonymous solution is easy: I just hand over my digitally-signed license and the website verifies the properties it needs in the various fields.
