Abstract: Disclosed is a system and method for verifying the authenticity of physical objects by implementing an immutable chain of physical object provenance. The invention provides for verifying the provenance of a unique physical object such as a collectible by processing an image of the collectible and associating it with identification information of the user and geolocation information associated with the collectible, and storing that information in a datastore. The invention then provides for generating a segment mask by submitting the image and one or more prompts to a segmentation component, which will return a mask that can be used to match a subsequent purported image of the collectible to verify its authenticity. Any subsequent changes will likewise be stored on the blockchain to provide an immutable chain of provenance.
