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. We 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. During the issue of passport, a watermark can be created based on the details of the holder full name and passport number and it can be hidden in the passport photo using watermarking technique. With the help of this technique, during the passport verification process at the checkpoint, computer can be used in scanning the passport photo to check whether the passport photo has been replaced by comparing the invisible watermark hidden in the passport photo with the holder€™s details including the full name and passport number.
