Abstract: Systems and methods subjecting a computer graphics object to a pseudo-random transformation to produce a surface-texture snapshot used to verify the authenticity of a host object. An example method includes generating a hash of a private manufacturer identifier, a product identifier, and a chain of ownership identifier and generating a three-dimensional surface using a first portion of the hash. The method also includes generating a texture pattern using a second portion of the hash and generating a surface-texture snapshot by mapping the texture pattern onto the three-dimensional surface. The surface-texture snapshot may be provided for imprinting on the host object. In some implementations, the surface-texture snapshot may be used as a first check in an authentication procedure.

Abstract: Systems and methods for time and location based authentication of a number associated with an object. An example method includes receiving a verification request from a requestor that includes a time-location stamp and a number obtained from the object and verifying that the number exists in a data store of numbers generated for objects by a product owner. The method also includes determining whether the time-location stamp is outside a constraint set by the product owner. Responsive to the time-location stamp being outside the constraint the authentication probability is set to a value indicating inauthenticity. Responsive to the time-location stamp being within the constraint, the method includes calculating an authenticity probability based on a velocity determined using the time-location stamp and storing the authenticity probability with the time-location stamp in the data store. The method may also include providing the authenticity probability to the requestor.

Abstract: Systems and methods use an origin pattern to verify the authenticity of a host object. The origin pattern includes a text-based serial number and a computer-graphics based surface-texture component. The serial number includes a public manufacturer identifier and an object identifier sequence that is based on a hash of a private manufacturer identifier and a private object identifier. The surface-texture component includes a two dimensional texture mapped onto a three dimensional surface, the generation of the surface being based on the hash. In response to an authentication request for an origin pair, the system may verify the serial number component exists in a data store and generate a challenge surface-texture component based on data in the data store. If the challenge surface-texture component matches, the system may use a time-location stamp to determine an authenticity probability and provide an indication of authenticity in response to the verification request.

Abstract: Systems and methods use an origin pattern to verify the authenticity of a collection of items or an entity offering items for sale. Example methods include receiving identifiers for items in a collection, determining the requesting entity is authorized to include the items in the collection, generating an origin pattern based on a hash of a private identifier for the requesting entity and a collection identifier, and providing the origin pattern for placement of packaging for the collection. Another example method includes generating a first digital identity origin pattern that is provided for display, receiving a verification request with a second digital identity origin pattern, and verifying that the verification requestor generated the first digital identity origin pattern, a fingerprint component of the first digital identity origin pattern matches a fingerprint component of the second digital identity origin pattern, and the verification request falls within a verification window.
