1. Introduction

Nowadays, Biometrics which are used such as fingerprint, face, iris..and so on,

applied to research an individual identity. In particular, Iris Recognition technology is

considered the advanced recognition technology and the highest reliability. This technology

is strongly developing such as Controlling facility access( house, laboratory,..), epassport in

national security system., credit card authentication.

With that advantages, the building applications of iris identification in deploying

passport authentication are completely satisfactory. E-Passport has widely used in many

countries in the world. In Viet Nam, on the way of integration and development, the

problem effectively control of an immigration, not only Vietnamese people but also

foreigner people are becoming complicated. Nowadays, this work is due to customs officials

carried out manually, based much on emotion. From the observation, With the desire to

build a system for deploying and e-Passport authentication in Viet nam, under the direction

of Prof. Dr. Nguyen Thi Hoang Lan, I have made a project about : “Building applications of

iris biometric authentication for ePassport authentication system”.

2. Analysis of building applications

2.1 Diagram of system functions

Figure 2.1 The block diagram of the application system function ePassport authentication

As well as biometric authentication system in general, e-passport authentication system also

includes 3 main types, corresponds to 3 main functions of system, that is:

Enrollment

Authentication

The database storage

However, within the framework of this project only focuses on building program in the

authentication function.

2.2 Technological solutions to system

Figure 2.2 Data structure in the RFID chip

This model is essentially the same the model of ICAO organization held out, except the

biometric information includes only DG2-Face, Encoded Iris DG4( Iriscode), ignoring

DG3-Encoded Finger(s).

Chip RFID is a smart chip without contacting with it. When using this card, we don’t need

to maintain a central CSDL or through CSDL to make authentication decisions. In the

authentication mode 1:1, Passport holders are reminded to look at the camera where the

picture is taken. This image which through the process of pretreatment to improve the

quality, would be extracted from selected features, encrypted form iriscode(template). If this

template is suitable to its value stored from verification card successfully.

2.3 Analysis of the functional design of the application program

When passengers ask for check in immigration, they have to present their passport. The

passport will be scanned with specialized equipment. The basic information in passport such

as: passport code, country code, full name of the passport holders …which is scanned from

RFID Chip in passport, will be saved. The biometric information includes the facial image

and iriscode on chip is also scanned directly.

Figure 2.4 The process of authentication of e-passports.

Thus the building program has some basic functions following:

1. Reading the DG1data:

HCST Authentication program will carry out read DG1 data in HCST’s RFID Chip and

compare information read with information printed in the HCST.

2. Reading the DG2 data:

When program carried out read DG2 data in HCST’s RFID Chip, the facial image of

passport holders would be shown. Security officers will carry out this match faces with

the faces of people with visual passports

3. Biometric authentication ( DG4 data)

Program matching biometric data obtained directly from presented passport holders with

biometric data stored in the Chip. If the matching process is successful and combined with

Dao Trung Phuong – SIC – PFIEV – K52 7

authentication on, then the trust is eligible passport is authentic and correct passport

holders are people described in their passports truth .

2.4 Libraries and programming tools

Due to the limited conditions of facilities, I have carried out the model test on the direction

of process validation testing with simulated data. The part related to the processing steps

required directly on the RFID chip and reader will be tested in next time.

CSDL tests : “E-passport Albania database” consist of 40 samples are downloaded from the

website : https://www.epassporte.com. Each template includes: 1file RFID chip contains

information, a facial image, iris capture 15 images at different angles of light which is the

first iris images already stored in the chip data iriscode.

Figure 2.7 Details of a sample in the database "E-passport database Albania"

Based on the data have carried out RFID chip emulator for each sample by the file.MAT. In

which stores information from DG1 -> DG16 of each sample. This chip is modeled as

shown below:

3. Results

Within the framework of this thesis, the results achieved as follows :

Building successful iris recognition algorithms guarantee the accuracy, integrity and

indisputable.

Deployed iris recognition algorithms into applications built ePassport authentication,

ensure against theft of personal information, anti-counterfeiting passports, improve

efficiency allows the authentication of e-passport holders.

Testing and performance evaluation of the application program ePassport

authentication database on the "E-passport database Albania"

4. Development

Need investment in equipment such as RFID chips, card reader, camera dedicated to

imaging the iris database to complete registration function of the system, as well as

environmental testing on actual.

To improve the functionality Terminal Authentication (TA) , Passive Authentication

(PA), Chip Authentication (CA) to ensure the e-passport can not duplicate.

Improved algorithms to reduce authentication time low as possible.
