authentication using water marking

ABSTRACT

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, which 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 that could be applied to disguise any color

difference that 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 by comparing the invisible watermark with the digest name

of the holder and passport number.

EXISTING SYSTEM

The passport documents contain holder name, passport number, and

signature of the holder, place of issue, date of issue, name of the

issuing authority and expiry date of the passport. In the current

checking points, all the above mentioned details of the passport

holder are verified. The photo present on the passport is compared

with the face of holder and if the both are tallied then the holder is

assumed to be authorized and is allowed to use the passport. Under

suspicious circumstances, the signature of the holder and the one

that is provided on the passport are cross verified. If they are tallied,

then the user is assumed to be valid. If the signature does not tally

with the one that is present on the passport, then the photo is

assumed to be replaced or altered. If this is detected, the person

intending to use the passport is considered illegitimate user and is

liable to prosecution. Even if the signatures match with each other

and if the difference between the photo and the face is considerably

large, it is also considered a crime and the signature is said to be

forged.

LIMITATIONS

The current system cannot detect the alterations made to the

photo of the holder on the passport document.

If the photo present on the passport document is replaced by

another, then the present system fails in effective detection of

such replacements.

Verification of hand-written signatures does not appear to be

sound technique because they are vulnerable to forgery.

If the signature of the holder is forged, then such forgeries

cannot be effectively detected.

PROPOSED SYSTEM

The aim of the proposed method is to develop a firm connection

between the passport’s photo and the passport details. In this case it

is possible to use the method of digital watermarking for confirmation

of passport’s information. Digital watermarking has been suggested

to play an important role in securing the business as it allows placing

an imperceptible mark in the multimedia data to identify the

legitimate owner and to prosecute the pirate.
