Identity network
BrightID seeks to provide everyone with the benefits of being verified as a unique person–namely, greater access to money, honest information, and greater choice in government. Traditionally, this kind of verification has relied on governments. The gatekeepers of unique personhood in BrightID aren’t governments, but trusted personal contacts.
BrightID is an identity network. It is conceptually similar to a social network, but its purpose is to allow people to prove to applications that they aren’t using multiple accounts. Connections are made and groups are formed, but for the purpose of ensuring that each person has exactly one account representing them. This is measured by a score given to each account; the score represents the probability that an account represents a unique person in the network.
