Remote Authentication of an Object Using a Signature Encoded in a Number of Data Portions
First Claim
1. A method of authenticating an object, the method including, in a computer system:
- receiving from a sensing device, indicating data, the indicating data being generated in response to sensing of coded data provided on or in a surface associated with the object, the indicating data being indicative of;
an identity of the object;
a plurality of signature fragments, the signature being a digital signature of at least part of the identity;
determining, using the indicating data, the identity and the plurality of signature fragments;
determining, using the plurality of signature fragments, a determined signature;
generating, using the determined signature and a key, a generated identity;
comparing the identity to the generated identity; and
, authenticating the object using the results of the comparison.

Abstract
A method of authenticating an object in which a computer system receives indicating data from a sensing device. The indicating data is generated in response to sensing of coded data and is indicative of an identity of the object and a plurality of signature fragments, the signature being a digital signature of at least part of the identity. The computer system uses the indicating data to determine the identity and the plurality of signature fragments. The plurality of signature fragments are then used to determined a determined signature, which is in turn used to generate a generated identity. The identity is then compared to the generated identity to authenticate the object.

-
sensing coded data provided on a surface associated with the object;
determining, from the sensed coded data, indicating data indicative of;
an identity of the object;
