1. A method of authenticating an object, the method including:
- sensing coded data provided on a surface associated with the object by an optical sensing device, the coded data being indicative of;
a position on the surface;
an identity of the object; and
,a part of a signature, the signature being a digital signature of at least part of the identity;
determining, by a processor and using the sensed coded data, a sensed identity and a sensed signature part;
determining, by the processor and using the position, a sensed signature part identity;
determining, by the processor and using the sensed identity, at least a determined signature;
determining, by the processor and using the determined signature and the sensed signature part identity, a determined signature part;
comparing by the processor the determined signature part to the sensed signature part; and
,authenticating by the processor the object using the result of the comparison.

Abstract
A method of authenticating an object by sensing coded data provided on or in a surface associated with the object. The coded data is indicative of an identity of the object and, at least part of a signature, the signature being a digital signature of at least part of the identity. The method includes using the sensed coded data to determine a sensed identity and a sensed signature part. The sensed identity is then used to determine at least a determined signature part, which is then compared to the sensed signature part, with the object being authenticated using the results of the comparison.
