FAQ

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”). BrightID will eventually support this, but it’s not our primary focus. If the only need is to verify claims, there are plenty of great existing solutions such as Sovrin.

BrightID can solve a problem that is difficult for other identity solutions–namely the problem of limiting each person to one account; and it does it in a way that doesn’t require personal data to be collected.

Can I use brightID for […]?

BrightID is excellent for

  • Keeping applications free from abuse
  • Voting, rating, anonymous reviews
  • Free trials, referrals, giveaways
  • Universal Basic Income

What’s with groups? Do I have to join one?

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.

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.

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.
