Abstract (en)
[origin: GB2426100A] Authenticity verification comprises conducting a transaction between first and second parties, the parties being respectively located at first and second locations remote from one-another, the outcome of the transaction being the provision by the first party to the second party of the right to an entitlement token, e.g. a ticket. Following the transaction outcome, data describing a written format for the entitlement token is transmitted from the first party to the second party. The entitlement token can be written (ie. printed) at the second location using the data describing the written format. A first signature for the written entitlement token is created at the second location, the signature being based upon an intrinsic property e.g. a scanned surface image of the written entitlement token, and stored in a signature database. A second signature for the written entitlement token can be created at a third location remote from the second location (upon presentation of the token), the second signature being based upon the same intrinsic property of the written entitlement token; and the attributes of the second signature compared with attributes of the first signature stored in the database to verify the authenticity of the written entitlement token. Alternatively the first signature can be written on the token itself and read upon presentation of the token and compared with the second signature.
