One of the serious problems is how to authenticate the passport document for its holder. The major factor of this authenticity is the corresponding of the Passport's photo with its holder. Most of the Passport document contains a holder's signature in addition, of course, to the full name. We propose a firm authentication method by extracting some features for the original name of the holder with the passport number and digest them in a form, by applying some techniques, that can be hidden in the passport's photo. The modern method of issuing a passport now is by using a computer in fixing the passport's photo (imaging). In using this method we could hide the invisible watermark which contains the digest name and passport number inside the passport's photo. During the hidden process there are many techniques could be applied to disguise any color difference appears during the hidden process. After using this technique, it is very simple to use the computer in scanning and verifying, at check point, that the passport's photo has been not replaced and that by comparing the invisible watermark with the digest name of the holder and passport number.
