This disclosure describes a distributed people registry that allows any individual to register for free. A registered user can store personal data, including unique personal identifiers, such as biometric data. The registry includes a personal vault for each user that is directly accessible only to the account owner. The user information is stored in the vault in a semantic triple structure, making it machine-readable. Third-party applications can reliably authenticate individuals using the vault. Transaction data for each application can be stored separate from the vault. The vault supports anonymized access to user’s personal information on an as-needed basis for every transaction. The personal vault for each user is stored at zero cost to the user. The personal vault enables anonymity in online transactions, reduces the amount of personal information provided to applications, and enables users to have self-sovereignty over their data.
