The prominent problem in passport authentication is to authenticate the passport document for its owner. The critical factor of this authentication procedure is to establish a correspondence between Passport's photo and its owner. A passport document contains holder details in supplement to the holder's signature. The authors propose an authentication scheme by extracting some details of the holder including passport number, converting them into a watermark and digesting them in a form by applying some techniques that can be hidden in the passport's photo. The computers have revolutionized the passport authentication process by using the computer in fixing the passport photo on the passport document during the issuing of passport and also verifying the passport at checkpoint by scanning.
