Abstract
Disclosed are various embodiments for verifying a consumer's identity during card-not-present (CNP) transactions using biometric data (e.g., fingerprint, retina scan, iris scan, handprint, voice sample, face scan, etc.) of the consumer obtained using a biometric security device. A zero-knowledge proof algorithm is used to verify the identity of a user initiating a transaction without disclosing personal information (e.g., biometric data) of the user to the issuer, merchant, recipient and/or other party, thereby preserving the privacy of the user.
