How is BrightID different from other identity solutions?
BrightID is a solution for knowing whether someone exists in a system only once.
There are ID systems that help someone claim ownership (of a website or a bank account), or get a third-party attestation about a personal attribute (such as “over 18”). Some of these solutions may allow users to manage their own claims or attestations (i.e. “self-sovereign identity”). Third-party applications may offer these services in conjunction with BrightID, but the core service of BrightID is determining uniqueness.
BrightID can solve a problem that is difficult for other identity solutions: the one-account-per-person problem. It does so in a way that doesn’t require personal data to be collected or attested by others.

What’s the purpose of groups?
Groups in BrightID are useful for one thing: to prove that you’re a unique person. Groups represent a small number of people that know each other well. They can be as small as three people. They don’t need to correspond to an existing real-world or online group. Groups help verify their members by connecting to other known, good groups; the strength of a group’s connections to other groups helps verify all its members.
Creating and joining groups is easy and tends to improve your score–which apps use to determine that an account is your real, primary account. You must belong to at least one group.
Why doesn’t BrightID use biometrics?
Biometrics (fingerprints, retina scans) are useful for determining whether someone belongs to a set of known people. They aren’t useful for stopping an attacker from creating duplicate identities–unless the test is administered by a trusted third party. BrightID uses relationships between close friends and relatives to verify unique personhood rather than biometric tests by third parties.
A third party may choose to use biometrics in conjunction with BrightID.
Does BrightID use facial recognition?
In order to stop an attacker from making duplicate identities, an AI would have to be able to recognize all attempts to alter or disguise one’s face. This is beyond the capability of an artificial intelligence for the foreseeable future.
BrightID uses trusted relationships between people to verify its users. This includes people’s ability to recognize someone in person using all available information, including recognizing their face. A real person’s ability to recognize another person far surpasses that of an AI.
Your name and photo exist to allow your connections to identify you and are not stored or used by BrightID outside of your device.
