Security scheme for authenticating object origins

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.

What is claimed is: 
     
         1 . A method comprising:
 receiving an authentication request from a requestor, the verification request including a time-location stamp and a number obtained from an object;   verifying that the number exists in a data store of numbers for objects generated by a product owner;   determining whether the time-location stamp is outside a constraint set by the product owner;   responsive to determining the time-location stamp is outside the constraint, setting an authenticity probability for the number in the data store to a value indicating inauthenticity;   responsive to determining the time-location stamp is not outside the constraint:
 calculating an authenticity probability for the number based on a velocity determined using the time-location stamp, and 
 storing the authenticity probability with the time-location stamp for the number in the data store; and 
   providing an indication of the authenticity probability to the requestor.   
     
     
         2 . The method of  claim 1 , further comprising:
 determining whether a minimum wait time has been reached since a previous verification request; and   responsive to determining that the minimum wait time has been reached, determining whether the time-location stamp is outside the constraint.
