US Patent 11700123 Asset-backed digital security tokens

A rights server system comprises a combination of digital fingerprint authentication techniques, processes, programs, and hardware that facilitate the creation, assignment, management, and enforcement of rights related to a physical object. An unspoofable, secure linkage is created between a physical object and an associated digital file through a digital fingerprint of the object. The digital fingerprint must be unambiguously derived from the object. The rights server manages interests in the physical object through issuing digital tokens which are linked to the associated digital file. Digital tokens linked to and backed by the physical object can serve as a type of currency or medium of exchange of real value.
