SYSTEM FOR AUTHENTICATING OBJECTS
First Claim
1. A system for authenticating an object, the system comprising:
- a sensing device for sensing coded tags printed on the object, each coded tags encoding an identity of the object and a signature fragment, an entire signature being encoded in a plurality of coded tags;
a processor for determining a signature fragment identifier associated with respective signature fragments, for generating the entire signature from the signature fragments and associated signature fragment identifiers, for decrypting the entire signature to obtain a generated identity;
means for comparing the identity encoded by the coded tags with the generated identity; and
means for authenticating the object using the results of the comparison.

Abstract
A system for authenticating an object is disclosed. The system has a sensing device for sensing coded tags printed on the object. Each coded tags encodes an identity of the object and a signature fragment. An entire signature is encoded in multiple coded tags. The system further has a processor for determining a signature fragment identifier associated with respective signature fragments. The processor also generates the entire signature from the signature fragments and associated signature fragment identifiers. The entire signature is then decrypted to obtain a generated identity. By comparing the identity encoded by the coded tags with the generated identity, the object is authenticated.
