Chapter 1: INTRODUCTION TO THE STUDY

1.1 Background to the Project

ATM known as Automated Teller Machine was invented by John Shepherd-Barron during the early 1960s. ATM is a cash dispensing machine at the requirement of cheque and pin number. Later on the machine was improvised to read magnetic strip cards (Verma, 2012). In Malaysia, ATM were introduced through MEPS in the year of 1996 (MEPS, 2014). ATM are undeniably important when it comes to money dispensing. Though there were some cases dealing with the vulnerabilities of ATM including hacking the software and breaking the ATM safe stealing money (FinanceTwitter, 2014). The ATM contains only two type of authentication that includes pin number and card validation. So a proper authentication and verification system was proposed by the developer to enhance validation and authentication to the current system. The developer’s proposed system contains fingerprint scanning, facial recognition, and user login as the authentication components

1.2 Problem Context

Nowadays in Malaysia the level of authentication given to ATM authentication remains same as with two factor authentication. This is very much insecure since the two factor authentication involves with pin number and the card. Someone with the capability of stealing the card and knowing the pin number makes the victim very vulnerable (Meggitt, 2016).

The problem is that this two factor authentication sometimes cannot validate all types of user. This in fact neglects certain users from using the ATM such as blind people and also the other problem is that if the card is stolen and the thief knows the pin number as well then there is more trouble(Popken, 2014). The other supporting problem is that when the user forgets the pin number then the user cannot use the ATM (Brooker, 2015).

These are the problem associated with two factor authentication. Sadly, no bank or financial institutes did manage to solve this issue that commonly occurs in our society. Most of the time these institutes does not want to implement new technology to the ATM because it might cost them to change or upgrade each and every ATM in this country (Lamagna, 2016).

1.3 Rationale

Therefore, to overcome this complexity or problem associated with two factor authentication can be handled through by implementing biometric validation using thumbprint verification and facial recognition (Spence, 2014). In this way the rightful owner of the account will be able to do money transaction regardless if even the owner is blind or the owner has forgotten their pin number. A lot of this minor issues that causes nuances to the users of the ATM can be avoided by implementing these sort of verifications that will ensure only the right owner of the account can use it with no issue (Muller, 2016).

1.4 Potential Benefits

1.4.1 Tangible Benefits

  • When requesting new card and pin number after losing it and also when the user forgets the pin number, the system enables them to temporarily use the system until they obtain new card and password thus making the user not wasting time waiting for the new card.
  • The amount lost to illegal ATM transactions from the bank is reduced and the bank is able to keep more money in their safe.
  • Number of new customers will increase on saving their money in that particular bank, thus increasing profit and popularity for the bank.

1.4.2 Intangible Benefits

  • Integration of the ATM is improved very much as the implementation of two biometric devices such as facial recognition and fingerprint scanning inside of ATM. As the validation of the system is increased the integrity if the system also very much increases.
  • As the three factor authentication is implemented on the ATM, the result of the user search is very much precise when it can verify thumbprint, facial image and pin number. So the search concretes on determining the right and correct user while maintain credibility of the system.
  • Reputation of the bank that implements this security implementation goes sky high as more and more people save their money on that particular bank. So in turn will increase the share of the bank in the market plus adding value to the bank.
  • Customers will be satisfied on saving their money on the bank that has this security features being implemented in the ATM. Customers also will be relieved of the threats that might happen implicating loss in their savings. Thus customers recommend that particular bank to other customers as well.

1.5 Target Users

The targeted users are all types of users. This system is made to encompass all types of users so that anyone and everyone is able to use the ATM machine.

1.6 Scope and Objectives

1.6.1 Aims

The aim is to analyse, design, and implement a secure level of ATM machines by using three step authentication.

1.6.2 Objectives

  • To investigate the problem associated with the current authentication used by ATM
  • To propose and design a system to improve the authentication of the ATM by integrating both fingerprint and facial recognition
  • To implement the proposed authentication system of the ATM
  • To evaluate  and test the proposed authentication system of the ATM

1.6.3 Deliverables

This three factor authentication benefits the user in these certain ways:

  • Increases the data confidentiality of the ATM machine
  • improve authentication system
  •  advance verification stages to access bank account through ATM machines

1.6.4 Nature of Challenges

The challenge that will be met upon creating this system mostly on reading and identifying fingerprint and facial recognition. Each user have their own fingerprint and face that is distinct from each and every one. So in order to read or scan, a proper algorithm has to be implemented. The scanned data has to be stored in the database. Thus, emerging another challenge on determining which database is suitable for storing such data. Also not to forget, what suitable or compatible programming language can be used to connect such devices and be able to integrate along with the database becomes a challenge as a whole. There is also an integration challenge where all the devices has to work with no errors of what.

Chapter 2: LITERATURE REVIEW

2.1 Introduction

Automated Teller Machine (ATM) is important to both the customers and to the bank company. Since the importance of ATM is undeniable, protecting the integrity of ATM is also important. As more and more customers use ATM, the bank customers become the main victim to illicit activities by criminals. They tend to steal the debit or credit card and also the number and use those to steal money. By the time the customers realise about this the thief gets away with all the money. This sort of menacing trouble is within in our society and by having multiple level of authentication only such issue can be tackled with (Mahmood and Shaikh, 2013).

2.2 ATM Machines

To define ATM, it’s a cash machine or cash dispenser which is an electronic computerized telecommunications device that allows bank customers access their bank account. This machine accepts money from the customer though deposits and dispenses money to the customer as well. ATM also allows other banking options to be done. ATM operates when inserted credit or debit card into the machine. That particular card contains the customer’s account number and the pin number embedded in the card’s magnetic strip. ATM verifies by communicating with banks computers checking for the balance and sends notice about the transaction. This brilliant machine was invented by John Shepherd-Baron, an inventor from UK. The idea was to have a cash dispenser operating 24/7 (Curran and King, 2008).

There are issues pertaining with ATM including both internal and external. External meaning that human factors that threat the integrity of the system and the factors are from illegal activities. Credit card fraud, shoulder-surfing observation attack, credit card skimming, and recording with hidden camera when users enter pin number into ATM. Such attacks or threats have made banks register immense loss. Not only the bank but also money of the customer is being stolen. The most common attack is the shoulder-surfing attack and this attack is commenced just by observing the pin entry by the customer and knowing it. So after stealing the credit card taking money from that account is very easy (Khan, Hasan and Xu, 2015).

Such attack is increasing every year and sadly the customers are lot legally protected by the credit card companies and banks. There are also other scams like deploying fake terminals, credit card cloning, and wormhole attacks. Sometime user cannot rectify between the real ATM and a fake ones and uses it, losing the card information. Credit card skimming works when customers enters their card through the card slot in the ATM, the skimming device installed will get hold of the card information. Also if a user wishes to pay using card after having dinner at a restaurant there is a possibility that their card might be cloned through card cloning device (Tade and Adeniyi, 2016).

2.3 Similar System

The similar system of online banking or ATM machines is present and is the two factor authentication using mobile phones. This particular system contains two authentications which is done in a secure manner. What the authentications are is the One Time Password generation and an SMS based mechanism. ATM uses two factor authentication in which the user must possess an ATM card and must remember pin number in order to use ATM. One Time Password (OTP) is created without the even connecting the client to the server (Aloul, Zahidi and El-Hajj, 2009).

Mobile phone that the user has acts as a token and creates a one-time password using factors that it collected. Software will be installed in the phone to create the OTP. SMS based authentication works when the generated password doesn’t work or rejected. So the mobile phone can request one time password directly from the server without even generating from the phone.  Server verifies the user after a message is sent from the phone through SMS (Aloul, Zahidi and El-Hajj, 2009).

In that message contains particular information about the user. After verifying, if the information is supplement, the server creates a random OTP number and send it to the user. User has limited to use the code before it expires. Such method requires both the client and server. The OTP algorithm are responsible for such random code generation. They are implemented to make users not be able to guess the next sequence. Sequence created must be random, unpredictable, and irreversible (Aloul, Zahidi and El-Hajj, 2009).

Image result for Two Factor Authentication Using Mobile Phones

Figure 1 ATM Similar System (Plivo, 2017)

Image above shows the similar system that is found that functions similar to a contemporary ATM. Image above describes as when a user creates an account or does transaction, the user is notified with a unique code that the user enters into the application to verify their action. The same concept is adapted in online banking transaction as well.

2.4 ATM authentication Method

2.4.1 Biometric Methods

Issues that threatens the integrity of the system can be averted through implementing more security layers which are multi-level authentications that reduces such threats to the bank accounts of their customers. Customers will feel more comfortable when using the ATM more than ever. Biometrics is one option that can be included into one of multi-level authentication that can be included. What is biometrics? It is a method on scanning and analysing biological data of a human. For example fingerprint, iris, eye retina, voice pattern, DNA, facial pattern, and hand geometry (Rao and Nayak, 2014).

For this system two biometrics have been chosen fingerprint and facial pattern. The reason that these both are being used because most government and companies use this due to the fact it is easy to deploy, cost effective, and ease of use of verification (Rathod, Iyer and Meena S M, 2015). Fingerprint of each individual is unique is because each fingerprint has arches, whorls, loops, valleys, ridges, and furrows that is different from one than other. Facial patterns also works with the same concept albeit it uses facial features such as nose, eye distance, ear placement, and lips. The image of the face is captured and facial patterns are analysed to be stored which then can be used as a template (Singh and Nandi, 2012).

For verification the same facial image of the person is captured and again the facial patterns are analysed after that it is checked with the template and if it matches then the user is verified. The advantages of using biometrics are the person is present at that time of the authentication, the biometrics trait cannot be forged or lost, biometrics systems are hard to break, have good accuracy, and finally it is cost effective. Also a multimodal biometric system has its perks whereby it improves security elements and eliminates problems during recognition stage (Shaukat, Aziz and Akram, 2015).

2.4.2 Architecture

How does the ATM work or functions? Automated Teller Machine is a data terminal that has two input and four output devices. In order to communicate like any data terminal, ATM connects to the host processor. The host processor then connects to the internet service provider and which is the gateway to ATM network. After connecting to the network the ATM becomes available the card holder which is the user. Most host processors supports leased line that allows host processor directly connect through telephone line (Bowen, 2006).

Leased line ATM are capable of handling thru-put therefore are placed at high volume locations. Such host processors are owned by bank institutions or owned by corporate service provider. Host processors that is owned by banks only supports bank owned ATM (Bowen, 2006).

2.5 Conclusion

To conclude this system, this system has three components those are user validation using username and password, fingerprint recognition, and facial recognition. The completed system comprises all these components and work together. This system works from user authentication by entering username and password, after that authenticating user for fingerprint, and finally authenticating user for facial recognition.

Chapter 3: DEVELOPMENT METHODOLOGY

3.1 Introduction

For the development of this project, three software developing methodologies have been considered. Those methodologies include Rational Unified Process Methodology (RUP), Prototyping and Waterfall. To develop any system a methodology is important as it provides guideline as well as provides solution for any error faced.

3.2 Rational Unified Process Methodology (RUP)

This methodology is a repetitive and adaptive system development tool that is now owned by IBM. RUP depends on timeline, important document model and unique team specialism. The project team utilise this methodology according to their need to create a robust software that meet project plan and the budget. RUP has six disciplines that needs to be followed. Those are business modelling, requirements gathering, analysis and design, implementation, testing and deployment. This methodology adopts an iterative method where it goes through several phases that is being used in many organisations. The phases are inception, elaboration, construction and transition (MyProjectManagementExpert, 2009).

At the first phase, the project plan is created and also use case or business case. In this phase everything is planned ranging from cost, risks, scope in order to develop a system with no bottlenecks. Without this phase it would be chaotic proceeding to the next step. Elaboration is the next step where the potential risks are resolved through solutions made by proper analysis. After planning out the solutions, plan of the entire project is structured. Prototypes are made to validate the risks that they have been taken care of. Developers choose which software to use and the budget for the development (MyProjectManagementExpert, 2009).

Next is the construction phase where codes are implemented into different parts of the system and this phase contains iteration that will increase if the size of the project is high. The system is tested till there is a fully working system completed with proper documentation that will be delivered to the customer. In the final phase transition, the product is delivered to the customer and they are trained to use the system. Updates and patches are released upon getting feedback from customers (MyProjectManagementExpert, 2009).

This methodology segments each development process into four phases that involves modelling, analysis and design, implementation, testing, and deployment (TatvaSoft, 2017). RUP is an object oriented and web based program or software development methodology. Such model also helps software engineers on guiding them, providing them with templates, and example for all aspects of software developing (TatvaSoft, 2017).

Advantages of using Rational Unified Process are is one which this methodology focuses on accurate and precise documentation. Moreover, customer or client requirements can be added throughout the methodology. When adding new requirements, it is based on the request management where it constantly updates or evolves the requirements (TatvaSoft, 2017).

Less integration is required throughout this project methodology since, the methodology itself contains integration process the entire time (TatvaSoft, 2017). RUP is an iterative model that allows developers to create a high level design of the application before beginning to build the actual product. After designing, a basic version of the application id built and then it is evolved into something better. Furthermore, RUP model makes developers design and develop application through step by step which eliminates flaws and defects in the system (Istqbexamcertification, 2012)

Disadvantages of RUP model is that each phase of the iteration is stagnant that contains no overlap. Each phase is rigid and it is on its own. Expensive system architecture or design problems might arise since not all the requirements are gathered in the foremost when designing and developing the application (Istqbexamcertification, 2012). Moreover, team members of the development team needs to be expert in their field so only then they can start to develop the application under this methodology. Designing and developing the system under this methodology might be confusing of its complexion and disorientation of processes (MyProjectManagementExpert, 2009).

Rational Unified Process (RUP) knows that conventional or traditional process shows only the single view of the process. On the contrary, RUP is explained according to these three perspective and they are dynamic, static, and practice perspective. Dynamic shows the phases of the model through time, static shows process activities that are active, and practice perspective advices on the good practices that can be used during the process. Conventionally RUP is described and explained by combining the static perspective and dynamic perspective (Sommerville, 2014).

3.2.1 Dynamic Perspective

Rational Unified Process is a phase based model that contains four distinct phases in the software process. Compared to waterfall model, in which the phases contains process activities, RUP phases are closely related more to business than technical aspects. Iteration in RUP works in two ways. Each phase undergoes through its own iterative process with results developing incrementally. At the same time, all the process goes through an iterative process like the image below portrays (Sommerville, 2014).

3.2.2 Static Perspective

Static perspective of the RUP concentrates on the activities that take place during the creation process. Such are known as workflows in the RUP explanation. Six core process workflows and three core supporting workflows are found in the processes. RUP is created in parallel with the UML so workflow of the description is associated with UML models. The six core models are business modelling, requirements, analysis and design, implementation testing, and deployment (Sommerville, 2014).

Good thing about presenting in dynamic and static perspective shows that phases of the development phases are not in correlation with specific workflows. During the early stages of the process of RUP, mostly time and effort is focused on workflows like business modelling and requirements while through later in the process, it is testing deployment that is focused most (Sommerville, 2014).

3.3 Prototyping Methodology

In this methodology, before implementing coding or design a disposable prototype is built to really understand the customer’s requirements. The prototype is created based on the current requirements. Using this methodology, the customer gets to view of the system that is about to be created, in other words customers get to see the mock-up so that they able to understand the requirements better. This methodology is important if there is a huge and complex system is about to be created (Istqbexamcertification, 2012).

When showing the mock-up to the client most of the system functions are not programmed. At the end of the methodology a full working completed system is delivered to the system. Prototype methodology is very useful when there is a lot of customer interaction needed. Systems like online and web services need frequent customer interaction so prototype methodology is suitable for these types of systems. Constant feedback from customer is important since this methodology is suitable when creating a system with good computer interface systems (Istqbexamcertification, 2012).

3.4 Waterfall Methodology

This model was the first methodology that was to be introduced. This model is noted as a linear-sequential life cycle model. This methodology is very easy to use and understand. Waterfall methodology requires previous phase to be completed before starting the next phase and there is no iteration. Projects that are small and there is no certain requirements are suitable to use waterfall methodology. At the final phase the project is reviewed to check whether the project is a success or failure. Testing is done after the completion of the development. Each phase of this model does not overlap (Istqbexamcertification, 2016).

Waterfall model

Figure 6 Waterfall Model (2016)

Waterfall methodology requires less customer interaction when developing the product. End product is then demonstrated and showed the functionalities of the system to the customer. Any failure after developing the product is a drawback and this adds cost on eliminating the error as well as updating the entire documentation. This methodology is suitable when the technology is understood to develop the product. The major setback of this methodology is that any error or oversight in any phase, the developers cannot rollback and have to deal the problem no matter what the cost (Istqbexamcertification, 2016).

3.5 Comparison between Methodologies

Rational Unified Process Waterfall Methodology Prototyping Methodology
Phases Inception, Elaboration, Construction, Transition Requirement gathering, System design, Implementation, Testing, Deployment of system, Maintenance Requirement gathering, Quick design, Building prototype, Customer evaluation, Refining product, Engineer product
Iteration Yes No Yes
Customer Involvement Throughout the project At the end of the project Throughout the project
Type of project Huge Small Small
Flexible phases Yes No Yes
Documentation Less Heavy Less

Table 1 Comparison Table

The methodology chosen here to develop the system is Rational Unified Process because this project is huge and the potential risks are analysed beforehand to reduce error, cost and time wasted to find solutions. The integration process takes less time to complete as it is done throughout this methodology. When developing this system, the devices that are required for scanning should work with the system prompting no error, so the integration matters a lot in this project and RUP suits just fine. Iterations in RUP that can be utilised very well in when developing this system

3.6 Conclusion

To conclude, compared to all of the methodologies, Rational Unified Process stands out to be the most suitable methodology for this project. Using this methodology, completing the project would be fast as well as effective to complete the project. Any changes or new requirements added, can easily be adapted into the methodology since it is an iterative process.

Using Visual Studio as the IDE will provide enough stability and scalability to use those scanning and recognition devices and work with the coded program.

Chapter 5 Primary Research

5.1 Introduction

For the primary research, the developer has decided to use questionnaire and interview as the data gathering method. Questionnaire and interview will help the developer on gathering the information and analysing it for the problem that is being faced by the users of the current existing system.

5.1.1 Questionnaire

Questionnaires are cost effective, quick and efficient in the way of collecting large amount of data from large number of respondents. This method is fast due to the fact that, the researcher does not need to be present when the questionnaire is being filled. Questionnaires are way too useful for large respondents when interview would be time consuming. When creating and designing questionnaire, the language used must be suitable and appropriate for the respondents so that they can understand (McLeod, 2014).

For investigating patterns and frequency questionnaires are very useful. User also will feel satisfied with the collection of data from questionnaire because it shows the respondents attitude and opinion clearly (Evalued, 2006). Questionnaires can be classified by being both quantitative and qualitative based on the questions that it has. Answers from closed ended questions are evaluated with quantitative method whereas answers from open ended questions are evaluated with qualitative method (Dudovskiy, 2016).

Some of the questionnaire advantages include high speed of data collection, low cost or no cost needed, and questionnaire contains high level of objective compared to other data collection techniques that are available (Dudovskiy, 2016). Moreover, other advantages of questionnaire include the data collected is simple to manage and analyze, respondents can take their own time to answer the questions, and questionnaires are fairly easy and quick for respondents to answer the questions (Evalued, 2006).

5.1.2 Interview

Interview is a private meeting between people asking the question and people who are answering the question. The person who answers the question being asked is known as interviewee while the person who asks the question is known as interviewer. Interview is conducted when the purpose is to get the viewpoint of others or to get to know each other. There are different sort of interview types such as personal interviews, evaluation interview, persuasive interview and many more (The Business Communication, 2014).

Interview allows the researcher to investigate issues in depth manner. It also allows an individual to express their opinion regarding any issues though it can be about sensitive information which people feel uncomfortable when discussing in a group. Interview adds human perception and understanding towards the data collected. The questions asked can be either open ended or closed ended. For this research the developer has chosen open ended and closed ended questions to conduct interview (Evalued, 2006).

Some of the advantages of interview methodology is that it is time saving, less expensive, selecting perfect candidate for the interview, and also interview allows to get a high response rate from the candidate chosen (The Business Communication, 2014).

Table 45 Analysis of Interview 3 Question 6

For the analysis of the interview, in question1, Mr Ryan, Mr Pavien agreed that not enough data has been given and are willing to give more information while Mr Tajuddin is not willing to give enough data mentioning that, enough data has been given to the banks. This question has shown that users not all are willing to give more information to have a secured transaction even though some are willing to do so.

In question 2, the interviewees, all of them have heard or seen or experienced about the attacks done on ATM to compromise security. This clearly shows that attacks done on ATM to compromise security on transaction is not just a small issue and every user of ATM knows of such threat exist.

In question 3, Mr Ryan, Mr Pavien, and Mr Tajuddin all of them mentioned more secure and better verification if biometric verification would be added to the ATM to increase the level of the transaction done. This question clearly shows that the users of this system agreed, upon increasing verification methods by including biometric verification, the level of having a secured transaction is much higher and safer.

In question 4, Mr Ryan and Mr Pavien answered that they would want fingerprint, iris and facial biometric verification to be added to the ATM while Mr Tajuddin answered fingerprint itself should be enough to for biometric verification to be added into the ATM. Through analysing their answers, it can be concluded that most of the users of the ATM would prefer more than one biometric verification to be on the ATM but some prefer just to have one biometric verification.

In question 5, Mr Ryan, Mr Pavien, and Mr Tajuddin all answered that they are willing to give their biometric information to the banks so that they can provide a better secure ATM transaction. So this can be concluded that, users of the ATM are willing to give biometric information such as fingerprint, facial or iris to the bank. This shows that users prefer biometric verification to be in the ATM.
