Confirming physical custody of objects

A system verifies that a user physically holds an item, such as a financial document, before approving a transaction. It prompts the user to show the item to a camera, then processes the captured image to create a unique digital fingerprint. If this fingerprint confirms the item's presence, its identifier is sent to a remote system to proceed with the transaction.

Why it matters: Filed before smartphones with high-quality cameras were ubiquitous. A phone's integrated camera and processing power can now easily perform the image capture and hashing described, making remote verification practical.
