Abstract: Systems and methods for peer-to-peer secure document exchange are disclosed. The system may allow a document provider to securely transmit a certified document to a document verifier using decentralized storage. The verifier system may generate a session key pair and transmit the session public key to a trusted API provider. The trusted API provider may generate a session nonce. The verifier system may transmit the session nonce to the provider system. The provider system may use the session nonce to retrieve the session public key. The provider system may encrypt a certified document using the session public key and store the encrypted certified document in the decentralized storage. The verifier system may retrieve the encrypted certified document by polling the trusted API provider based on the session nonce. The verifier system may decrypt the encrypted certified document using the session private key.

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.
