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 steps of:
- receiving from a sensing device indicating data of each of a plurality of regions of a surface associated with the object, the indicating data of each region being indicative of;
an identity of the object; and
a signature fragment, the signature fragment being a fragment of a digital signature of at least part of the identity;
determining, using the indicating data of each region, the identity, one of the signature fragments and a signature fragment identifier associated with the one signature fragment;
determining a determined signature by arranging the plurality of signature fragments according to their associated signature fragment identifiers;
generating, using the determined signature and a key, a generated identity;
comparing the identity to the generated identity; and
authenticating the object using the result 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.
