Secure peer-to-peer connections between mobile devices

This invention describes a method for two mobile phones to establish a direct communication link. One phone displays a unique, temporary code, similar to a QR code, which the other phone scans with its camera. The scanned code contains all the necessary information for the two devices to securely connect and communicate with each other.

Why it matters: Filed in 2022, this invention predates the significant advancements in spatial computing and mobile AR frameworks. The classifications, particularly "Mixed reality," suggest using the code as a fiducial marker for spatial awareness. The ability to reliably use such codes for real-time pose tracking and intuitive spatial user interface inputs, enhancing secure pairing and interaction, has become substantially more robust and accessible on standard mobile devices since then.
