Privacy-Protecting Biometric Service
Assigning a unique identifier to a participant is the critical initial enrollment step, requiring precision and repeatability. It is a quality-in, quality-out foundational moment. The iRespond digital identity solution primarily relies on iris biometrics, the best modality after DNA for accuracy and reliability. Other modalities, such as finger or face can be used instead, or in combination with iris.
When a new participant is enrolled, an encrypted biometric template is created from their iris scan and a randomly assigned 12-digit number is drawn from a pool of 90 billion numbers. On subsequent visits, the identity of the participant is verified when their template is matched and the system returns the original 12-digit unique identifier. The system operator uses the pseudonymous identifier within their ecosystem to positively ID the participant.
