Abstract: User identity is verified using license keys issued during a pre-registration process. In one embodiment, members of a defined community communicate with other members of the community using uniquely identifying PKI keys. In one embodiment, the identity of a user is assured by having a system-level administrator issue license keys and pre-register the user. In one embodiment, during a pre-registration process, a setup server may be accessed to generate a private license key that will be used to secure and encrypt all communication from one user to another.
