Chapter 1 Introduction 1.1 Overview Nowadays, Biometrics becomes important in our life. Since it has a high security and convenient, so that people use Biometrics technology on anything. Such as, door access control, border control, banking, identify people, intelligent house, etc. The application is very diverse and their capacity of development is very large. The intelligent house becomes popular for the past few years. It can provide a safety and comfortable to the householder. But the security is very important, it must be identify the house holder accurately and prevent the system to make a mistake for identification. So that, we need to build a system like the security to make a identity and monitoring the security of building. 1.2 Background Information In fact, Hong Kong building security is decreased. The thief is increased to make the people safety to be damaged. So, we must improve the building security and the management. By the way, when we come back to our building, we may use words of password or the key to open the building door. That is so trouble and inconvenience. Biometrics technologies can help us to improve the security and easy to management. So, we may use the biometrics technologies to maintain our final year project. 1.3 Structure of the Final Year Project Report The remainder of this report is divided into Seven Chapters. They are as follows: - Chapter 2 covers the literature review on the design research of biometrics system. We find a lot of the information and image from Internet. Chapter 3 discusses on the design criteria of hardware system, software, layout and database Chapter 4 presents the details of the components of the hardware software, workflow and database about our system. Chapter 5 describes the performance evaluation of the developed system about the principle of biometric enrolment and verification. Chapter 6 and 7 describe the enrolment and verification procedure of how to capture and record of our recognition system. 1

Chapter 8 concludes the report and out lines the contributions of the project. The limitations were highlighted and suggestions are made for further development to improve the system. 2

Chapter 2 Literature Review 2.1 Introduction That part is literature review. It means we will show you all our research before our project starting. And the research should be about example of biometric system, layout of the hardware system, layout of the software interface, etc. We will show you all of our research for the final year project. 2.2 Introduction to Biometrics Technologies 2.2.1 What is Biometrics? The term biometrics refers to the emerging field of technology devoted to the identification of individuals using biological traits or behaviours [1]. In practice, this means capturing an image of a unique feature of an individual such as a fingerprint, hand, eye or face, and comparing it with a template captured previously. For ease of explanation this has been over-simplified, but in essence this is biometric technology works. Human Recognition Systems works with 4 key biometric technologies: Iris Recognition Hand Recognition Fingerprint Recognition Facial Recognition 2.2.2 History of Biometrics 1800s identification largely relied upon "photographic memory" [2]. This was changed in 1883 when Alphonse Bertillon, a clerk in the Paris police prefecture, introduced physical measurement system (which came to bear his name: bertillonage) Bertillon based his system on the claim that measurement of adult bones does not change throughout life. Measurements in his system included: height, length, and breadth of the head, the length of different fingers, the length of forearms, etc (Bertillon estimated that the odds of duplicate records were 286,435,456 to 1 if 14 traits were used. After this, the police used finger printing, which was developed by Richard Edward Henry of Scotland Yard, instead. Essentially reverting to the same methods used by 3

the Chinese for years. However the idea of biometrics as a field of study with useful identification applications, was there and interest in it has grown. Personal Identification Numbers (PINs) were one of the first methods used for identification. There are also methods that involve passwords and physical tokens e.g. smart cards. There are a number of problems associated with this kind of identification. People forget passwords, lose tokens, reuse passwords, write them down, tokens can get stolen. The recognition of the above does not mean the identification of the person providing it - they could be presented by anybody. With the advent of e-commerce brings increased pressure on IT managers to provide partners and customers with means of identification to access corporate networks. This results in a deluge of passwords and means of access, which are often forgotten, misused or lost. With the increased population accessing these networks the risk of attacks on the networks is increased. Companies are turning to Biometric Systems to bring tighter security to their computer networks. Today we have the technology to realize the aims, and to refine the accuracy of biometric identification, and therefore the possibility of making it a viable field. Soon biogenetics technology will be used in every house hold and it is getting increasingly more and safer to use biometric technologies in order to better our life. 2.2.3 How does it work? False Reject Rates: For most applications, letting the good guys in is just as important as keeping the bad guys out [3]. The probability that a biometric device won't recognize a good guy is called the "False Reject Rate." The False Reject Rates quoted for current biometric systems range from 0.00066% to 1.0%. A low False Reject Rate is very important for most applications, since users will become extremely frustrated if they're denied access by a device that has previously recognized them. 4

There has a example may be helpful. A company with 100 employees has a biometric device at its front door. Each employee uses the door four times a day, yielding 400 transactions per day. A False Reject Rate of 1.0% predicts that every day, four good guys (1% of 400) will be denied access. Over a five-day week, that means 20 problems. Reducing the False Reject Rate to 0.1% results in just two problems per week. A low False Reject Rate is very important for most applications, since users will become extremely frustrated if they're denied access by a device that has previously recognized them. As mentioned previously, the combination of a low False Reject Rate plus a simple keypad code provides virtually unbreakable security. Equal Error Rates: Error curves give a graphical representation of a biometric device's "personality." The point where false accept and false reject curves cross is called the "Equal Error Rate." The Equal Error Rate provides a good indicator of the unit's performance. The smaller the Equal Error Rate, the better. Validity of Test Data: Testing biometrics is difficult, because of the extremely low error rates involved. To attain any confidence in the statistical results, thousands of transactions must be examined. Some error rates cited by manufacturers are based on theoretical calculations. Other rates are obtained from actual field testing. Field data are usually more reliable. In the case of False Reject rates, only field test data can be considered accurate, since biometric devices require human interaction. For example, if the device is hard to use, false reject rates will tend to rise. A change in the user's biometric profile could also cause a false reject (a finger is missing, for example). None of these conditions can be accurately quantified by purely theoretical calculations. On the other hand, False Accept Rates can be calculated with reasonable accuracy from cross-comparison of templates in large template databases. 5

Currently, most field test error rates have been generated by various biometric manufacturers using end-user data. Tests have also been conducted by independent laboratories such as the U.S. Department of Energy's Sandia National Laboratories. The most recent test released by Sandia was performed in 1991. It's important to remember that error rates are statistical: they are derived from a series of transactions by a population of users. In general, the larger the population and the greater the number of transactions, the greater the confidence level in the accuracy of the results. If the error rate is reported at 1:100,000, and only 100 transactions were included in the study, the confidence level in the results should be very low. If the same error rate was reported for 1 million transactions, the confidence level would be much higher. The magnitude of the reported results affects the size of the sample required for a reasonable confidence level. If the reported error rate is 1:10, then a sample of 100 transactions may provide a sufficient confidence level. Conversely, a 100-transaction sample would be too small if the error rate was reported as 1:100,000. 2.2.4 Applications in Biometrics There are 9 biometrics applications: [4] Physical Access Control Logical Access Control Justice/Law Enforcement Time and Attendance Border Control/Airports HIPAA Financial/Transactional Integrators/Resellers Safes, Door Locks 6

Police forces thought the world use AFIS technology to process criminal suspect, match finger images and bring guilty criminals to justices. A number of biometrics vendors are earning significant revenues in this area. Banking Bank has been evaluating a range of biometrics technologies for many years. Automated Teller Machines (ATMs) and transaction at the point of scale are particularly vulnerable to fraud and can be secured by biometrics. Other emerging markets such as telephone banking and internet bank must also be totally secure for bankers alike. 7

2.7 Summary After the research that, we find many about the information of biometrics and many different kinds of the biometrics system. In fact, there were many technologies were used the biometrics technology. It is the truth and it must be more popular in the future. Now a day, many old systems are displaced by the biometric system. For example: access control system, payroll system, banking system, etc. During the project development, the biometric hardware is used. There are TiFace system, U are U fingerprint system. TiFace system enables to capture and enrol user s face. U are U fingerprint system is use to capture and enrol user s fingerprint. So, we have to use the biometric in the future life. 12

Chapter 3 Development Methodology for Multi-Biometrics Recognition System 3.1 Introduction In this part, we will tell you about our first development methodology. What kinds of hardware did we use. Why we use that hardware. What kinds of software did we use. Why we use that software. And we also post our first layout design in that part. We will all tell you the answer 3.2 Design Consideration of Hardware System Fingerprint recognition represents the oldest method of biometric identification. Its history is going back as far as at least 2200 BC. The use of fingerprints as a personal code has a long tradition and was already used by the Assyrians, the Babylonians, the Chinese and the Japanese. Since 1897, dactyloscopy (synonym for non-computer-based fingerprint identification) has been used for criminal identification. A fingerprint consists of ridges (lines across fingerprints) and valleys (spaces between ridges). The pattern of the ridges and valleys is unique for each individual. [17] There are two major methods of fingerprint matching: Minutiae matching and global pattern matching. The first approach analyses ridge bifurcations and endings, the second method represents a more macroscopic approach. The last approach considers the flow of ridges in terms of, for example, arches, loops and whorls. As the equal-error-rate is low, therefore fingerprint recognition is very accurate. The prices of such systems compared to other biometric systems are quite low and the user acceptance is very high. The strength of fingerprint identification is, that it can be deployed in a varied range of environments. Fig. 3.1 Types of fingerprint [18] 13

There are 6 types of sensors for fingerprint recognition: Optical Fingerprint Sensors Themalelectric Sensors Capacitive Sensors E-Field Sensors Touchless Sensors Surface Pressure Sensor Fig. 3.2 Optical Fingerprint Sensors [19] Fig. 3.3 Surface Pressure Sensor [20] Fig. 3.4 Capacitive Sensors [21] The template size varies from 100 bytes to 1500 Bytes depending on the algorithm and the quality of a fingerprint. Nevertheless, very rarely there are fingerprints without any minutiae-points that leads to a failure to enroll (FER = Failure to Enroll Rate). It is also difficult to extract the minutiae points accurately when the fingerprint has got a low quality. 14

Introduction of facial recognition Facial recognition systems are built on computer programs that analyze images of human faces for the purpose of identifying them. The programs take a facial image, measure characteristics such as the distance between the eyes, the length of the nose, and the angle of the jaw, and create a unique file called a "template." Using templates, the software then compares that image with another image and produces a score that measures how similar the images are to each other. Typical sources of images for use in facial recognition include video camera signals and pre-existing photos such as those in driver's license databases. [22] Computers can do increasingly amazing things, but they are not magic. If human beings often can't identify the subject of a photograph, why should computers be able to do it any more reliably? The human brain is highly adapted for recognizing faces - infants, for example, remember faces better than other patterns, and prefer to look at them over other patterns. The human brain is also far better than computers at compensating for changes in lighting and angle. The fact is that faces are highly complex patterns that often differ in only subtle ways, and that it can be impossible for man or machine to match images when there are differences in lighting, camera, or camera angle, let alone changes in the appearance of the face itself. Fig. 3.5 Facial geometry example [23] Fig. 3.6 Correct recognition example [24] 15

All of this makes face recognition ideal for high traffic areas open to the general public, such as: Airports and railway stations Casinos Cashpoints Stadiums Public transportation Financial institutions Government offices Businesses of all kinds Fig. 3.7 Facial recognition in airport [25] 16

3.3 Design Consideration of Software We choose macromedia flash and adobe Photoshop for our design software. Why we use that two software for design development? It is because macromedia flash is so powerful. It can be used actionscript for many different of animation. Although, it is easy to use and popular in the design area. The second point is we don t want to have a static and boring interface. So, we decided to use flash animation to replace of static picture interface. It can attract the people to use our system and make the system more interest. In the internet, many people used that two software. It is the brand name power and that software is really good for design. On the other hand, Photoshop can help us for tuning the photo color, light, size, effect, etc. It also can help us to make the picture be good. 3.4 Graphics Design and Layout Fig. 3.8 First Visitor mode layout 17

Fig. 3.9 Second Visitor mode layout. Fig. 3.10 Clubhouse mode layout 18

3.5 Structure of Database Design The following Fig. 3.11 is our first development of database structure design. It only consists of 4 tables: tblhouseholder, tblbuilding, tblvisitoryymmdd and tblfloorflat. That is our first developed schema. Fig. 3.11 Database schema of Biometrics System 19

Chapter 4 Details of the Multi-Biometrics Recognition System 4.1 Overview In this part, we finished to discuss and develop all the kinds of tool should we use. We will use two hardware for the system. It should be Face recognition and fingerprint hardware. And we will tell you the function of our biometric system. It has three different parts of the recognition system, please refer to Fig. 4.1. Finally, we choose the software, hardware and the final layout. We will show you all the things in the following. Fig. 4.1 Structure of System 20

4.2 Workflow of Recognition System The following two figures 4.2 & 4.3 are our workflow of the building security system and clubhouse system. Entry Select Mode Visitor Input Floor and Flat Householder Facial Recognition Enroll Face Invaild Check database & identify Enroll Fingerprint Vaild Open door Open door Fig. 4.2 Workflow of Building security system 21

Entry Select Login/Logout Logout Login Login mode Logout mode Facial recognize Facial recognize Invaild vaild Invaild vaild Check database Check database Store login time to database Store logout time to database Fig. 4.3 Workflow of Clubhouse system 4.3 Function of Recognition System There are three parts of our recognition system. It consists of Administration Tools, Building security system and Clubhouse system. 4.3.1 Function of Administration Tools Actually, householder and visitor also need to enroll fast when they want to use the biometric system. We make an enrolment to analysis this problem. Householder can come to our office to use the householder enrolment system. They only need to put their face in front of the camera. Their face record will store to our database for verify used. They also need to type their information (e.g. name, 22

gender, and floor no., flat no., etc.) to our database used. It is used for comparison. 4.3.2 Function of Building security system We design that householder mode is for householder using. They are no need to remember the word of password for house entry. It is because the entry password always changed a time. The householder may forget the password or remember the wrong one. So, Householder mode system can help person easily for entry. They only put their face in front of camera. If they are our householders then the door will open automatically by our system. Nowadays, people visit to their friend house. They must write down their personal information (e.g. name, id, gender, visit reason, visit room no.) in the building entry control. It is because the building needs to protect their householder safety and giving record. It may make the visitor inconvenient. So, we make a visitor mode for visitor using. It can help visitor more convenient, Visitor only put their face in front of camera and fingerprint to record their personal data. That should be fast and more convenient than the paper record. 4.3.3 Function of Clubhouse system Clubhouse is to be more popular to the new building. Householders can use their own clubhouse facilities. When they used the clubhouse facilities, they need to make a paper rent. That is not convenient and trouble. So, we make a clubhouse biometric system for householder using. They only open our system and put their face in front of the camera. Our system will record their login time. Otherwise, when they want to logout and leave that they also use our system to record their logout time. They can use our clubhouse easily. When you finished your playing from clubhouse, you need to pay the free to the clubhouse using. We make a payroll system for clubhouse payment. Householder only put their face in front of camera. Our database will search your clubhouse login time and logout time used for calculate the price. When you know the price that you only pay the money to our staff. He will help you to finish the payment process. 23

4.4 Hardware of Recognition System We choose facial recognition and fingerprint for our system used Facial recognition systems are computer-based security systems that are able to automatically detect and identify human faces. These systems depend on a recognition algorithm. The first step for a facial recognition system is to recognize a human face and extract it fro the rest of the scene. Next, the system measures nodal points on the face, such as the distance between the eyes, the shape of the cheekbones and other distinguishable features. Facial recognition is a good biometric system and it is too convenience and user-friendly. So that, we use facial recognition for our system used. For the fingerprint reason, we found that following good points: More securable than passwords by intercepting use and approach of Unauthorized people whose identification is not registered. Free from inconvenience to upgrade and remember passwords and the company It can save much cost to manage passwords. Fast and exact perception with high technology of finger print identification. Adopted dsp system that is to calculate moving direction and distance without Password by the image perceiving sensor. No roller and soft movement thanks to less rubbing resistance. Finally, fingerprint is easy too use, user-friendly and too cheap in the kinds of biometrics devices. 24

4.5 Development Software use Macromedia Flash Fig. 4.4 Marcomedia Flash [26] Adobe Photoshop Fig. 4.5 Adobe Photoshop [27] These two design tools are very powerful and easy to use. It can help us to analysis all the design problems. And we can make many different effects by that two software. It is very popular and great. So that, we used the tools for our interface layout design. Programming tools Fig. 4.6 Visual Basic 6.0 [28] Visual Basic 6.0. It is very easy to learn. It seen that very simple and comfortable for user programming. Finally, it also is a popular programming tool in the common program company. 25

4.6 Software needs and setup The basic software needs to install of the system are below: Flash Player 8.0 TiFace Runtime TiFace SmartGate SDK Futronic Fingerprint SDK The server and driver of the system needs are below: MySQL Server 4.0.x MySQL ODBC 3.51 Driver For easy to manage the database, we suggest to install these software are below: MySQL Administrator MySQL Query Browser Now, I will show you how to create new database account and restore the table in database form sql backup file. Step1. Use MySQL Administrator to create a new account. The MySQL user and password also is ive. Then, click Apply changes. The user will be created. Fig. 4.7 Create MySQL user 26

Step2. Open the sql backup file to restore the table needs in the database. It will create the schema ive_fyp automatically. Fig. 4.8 Restore the backup file Next, I will show how to share the folder. This folder is used to store householder and visitor s template and photo. Step1. Create a folder userdata in your any local drive. E.g.: C drive. Step2. Share this folder and set the permission of Everyone to Full control. Fig. 4.9 Permission of the folder 27

Step3. Create two folders householder and visitor in the userdata folder. Fig. 4.10 Folder of householder and visitor Then, I will show you how to change the server ip of the system connect. Step1. Open the config.ini file in the same level of folder. Step2. Modify the IP and enter the correct server IP. For example, you MySQL server s IP is 192.168.0.1.

Chapter 5 Evaluation of Multi-Biometrics Recognition Systems 5.1 Overview We would like to tell you our biometric system. It s all of good points in the popular area. And we also have any short points for future improvement. 5.2 Principle of Biometric Enrolment and Verification For the good side, people no need to remember the word of password for entry to their building. They no need to use any key or find other people to help them open the door. Our biometric system can easy to help people only put their face in front of the camera for open the door. It seen that it is very convenience, comfortable and user-friendly to our customer. For the bad side, when a householder sometime wears glasses, sometime not wear glasses. Our facial recognition system may verify failed for their glasses or cap. It is because our system is followed the capture face data to compare the person s face. If the person wear glasses or cap, it may verify failed. On the other hand, if the area has not enough light. It also may distort the verify %. It is because if the area has not enough light, then the camera can not capture the face data fully and immediately. 5.3 Summary In fact, all of the technology also has good and bad points. Facial recognition system also has that two points. But Biometric system really can help people to make the world convenience and more easy. So that, biometric system also can help human to analysis many problems. We may improve the biometric technology as soon as possible. It is because it may be the future one of the main technology. 38

We will test it 20 times to get the result of its FAR and FRR. It cans test the reliable and accuracy of the system. 7.2 Verification of Result FAR and FRR of Facial recognition: No. of correct acceptance (a) No. of false rejection (b) False Rejection Rate (FRR) b / (a + b) 15 5 0.25 Table 7.1 FRR rate of facial recognition No. of correct rejection (a) No. of false acceptance (b) False Acceptance Rate (FAR) b / (a + b) 20 0 0 Table 7.2 FAR rate of facial recognition 7.3 Summary To summarize, the FRR of facial recognition is a little bit high. It is 0.25%. Sometimes, it cannot verify properly. It is because the light, glasses, cap may affect the system to verify. Although the FRR is a little bit high, the FAR is 0. It shows that the system have a high reliable. And the system have a high accuracy to verify the user. 59

Chapter 8 Conclusions and Further Development 8.1 Overview Base on the important of biometrics technology, it is popular and user-friendly to displace many older technologies and systems in the future technology development. 8.2 Contribution of Final Year Project The achievements and contributions of this project can be summarizes as follows:- We are developed the three parts of the recognition system. There are Administration Tools, Building Security System and Clubhouse System. It is ready to apply in the building. This recognition is convenience and safety for security management. We also need to improve our technology, security and method for biometrics system built up process and developed any great ideas. They are no need to remember the word of password for house entry. It is because the entry password always changed a time. The householder may forget the password or remember the wrong one. Now, they only use their face to make an entry and no need to bring smartcard and remember the password. 8.3 Discussion on the Project Limitation When a person sometime wears glasses, sometime not wear glasses. Our facial recognition system may verify failed for their glasses or cap. It is because our system is followed the capture face data to compare the person s face. So, the person enrolls the face record that he has no wear any glasses or anything on his face. If the person wears glasses or cap to verify, it may verify failed. On the other hand, if the area has not enough light or in a dark area. It also may distort the verify %. It may verify failed. It is because if the area has not enough light, then the camera cannot capture the face data fully and immediately. 60

8.4 Further Proposal After this project, we have other further ideas. The further ideas are below:- Administration Tools can generate the report of householder or visitor. Add Chinese interface of the building security system. Send the email or signal to householder when visitor come. Payroll monthly statement for members. Car entry and exit recognition system for car park Use face recognition to identify the householder and open the gate Record the entry and exit log for security The householder no need to bring the car park card for entry used 61
