1. A device for authenticating an object, the device including:
- a sensor for sensing coded data provided on or in a surface associated with the object, the coded data encoding;
an identity; and
, at least one part of a signature, the signature being a digital signature of at least part of the identity;
a processor for;
determining, from the sensed coded data, a sensed identity and at least one sensed signature part;
causing authentication of the object using the determined identity and the at least one sensed signature part.

Abstract
A sensing device for authenticating an object. The device includes a sensor for sensing coded data provided on or in a surface associated with the object. The coded data encodes an identity and, at least one part of a signature, the signature being a digital signature of at least part of the identity. The sensed coded data is then used by a processor, to determine a sensed identity and at least one sensed signature part, which are then in turn used to authenticate the object. The processor may form part of the sensing device, or be connected to the sensing device via a communications system.

20. A computer system for authenticating an object, the computer system being for:
-
receiving from a device, indicating data, the indicating data being determined 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;
at least part of a signature, the signature being a digital signature of at least part of the identity;
determining, from the indicating data, a received identity and at least one received signature part;
authenticating the object using the received identity and the at least one received signature part.
