SECURITY DOCUMENT SCANNER
First Claim
1. A sensing device for use with a security document, the security document having disposed thereon or therein coded data including a plurality of coded data portions, each coded data portion being indicative of an identity of the security document and a signature part, the signature part being a part of a digital signature of at least the identity, the sensing device including:
- a sensor for sensing a plurality of coded data portions; and
,a processor for;
determining, using sensed coded data portions, a sensed identity, a plurality of signature parts, and an identifier for each signature part;
generating a sensed signature from the plurality of signature parts by arranging signature parts according to respective identifiers;
determining a generated identity from the sensed signature; and
authenticating the security document by comparing the sensed identity and the generated identity.

Abstract
A sensing device for use with a security document is disclosed. The security document has disposed thereon or therein coded data including a plurality of coded data portions. Each coded data portion is indicative of an identity of the security document and a signature part. The signature part is a part of a digital signature of at least the identity. The sensing device has a sensor for sensing coded data portions and a processor. The processor determines, using sensed coded data portions, a sensed identity, a plurality of signature parts, and an identifier for each signature part, generates a sensed signature from the plurality of signature parts by arranging signature parts according to respective identifiers, determines a generated identity from the sensed signature, and authenticates the security document by comparing the sensed identity and the generated identity.
