Wireless person-to-person remote identity verification system

Standard Patent for Non-Face-to-Face Identity Verification

This technology relates to an identity verification system, specifically a peer-to-peer, non-face-to-face system utilizing wireless communication. It operates by registering only the information necessary for verification on an on/off-chain—without storing personal data—and then verifying certificates using individual public keys on personal devices to generate integrated certificates.

The advantage of this technology is that the peer-to-peer, non-face-to-face identity verification system, which uses wireless communication, allows for the exchange of electronically signed confirmations. These can be verified against public keys registered on the on/off-chain, enabling the secure, non-face-to-face exchange of verified certificates.

Furthermore, because it can generate certificates that confirm event participation, organizers of workshops, conferences, exhibitions, or meetings can quickly and accurately verify the attendance of numerous participants at the venue simultaneously.

Key Features

• Registering one or more pieces of user registration information—including user identifiers, public keys, copies of cryptographic keys, and device identifiers—on an off-chain or on-chain.
• A peer-to-peer, non-face-to-face identity verification system using wireless communication, designed to exchange signed certificates between devices where user registration information is already registered.
• Generating a first certificate signed with the user identifier and private key of the device user, transmitting it to a second device via near-field communication, and receiving a second certificate signed with the user identifier and private key of that device user from the second device.
• A first device that verifies the second certificate received using the public key of the second device registered on the on/off-chain; and a second device that generates a second certificate signed with the user identifier and private key of its user and transmits it to the first device via near-field communication.
