The UNS network consists of Guardian nodes representing users, and Gatekeeper nodes representing services. Together, the UNS nodes form a chain of trust between any user and any service. Guardian and Gatekeeper combine direct and out of bounds communication to verify User and Service.1
How UNS Authentication works
Each user chooses a Guardian they trust.2
UNS authentication relies on trusted devices protected with biometrics.
User installs the UNS authenticator app which generates a self-signed security certificate when a user registers for an account.3
Authentication is proof that the user has physical possession of their registered device and is able to unlock it.
Each Services chooses a Gatekeeper they trust.
Services register their namespace with their Gatekeeper, where the namespace is the set of all possible account identifiers for that Service.
When a user registers for an account on a namespace using UNS, the Gatekeeper associates the user’s unique account identifier with an anonymous hash provided by the user’s Gatekeeper.4
