The main objective of this report is to convey and implement a bank locker security system based on two-factor authentication that improves the safety and security of bank lockers. In this system, only the authentic users recover the possessions from the lockers and the two independent authentication used which are fingerprints, biometric and OTP sent over GSM network.

The rapid application development methodology project life circle is followed in order to develop the system efficiently. The program was developed in Arduino Integrated Development Environment. This report presets details on architecture, integration and different design aspects of bank locker security system. The fingerprint biometric can deliver a high level of security by discounting the need of remembering PINs, multiple passwords and no necessity of carrying keys and identified proof.

The OTP is required to access the locker even if fingerprint biometric compromised. Wide operating range, low cost of equipment, high security and reliability are some of the major advantages of this project. It is envisioned that the bank locker system based on two-factor authentication shall eventually replace the manual traditional methods followed in bank locker systems and hence provide feasible way for a better locker service.

The proposed bank locking system based on two-factor authentication provides high performance, security, reliability, and robustness. The fingerprint biometric which is unique and “One-Time Password” sent to user’s phone which has time expiration are referred for two-factor authentication. Throughout the project, a lot of knowledge, troubleshooting of problems and finding solutions.




1.1       Background of the study

People are more concerned about their safety of valuable things and accessories which are hardly earned like jewelry, cash, certificates and etc. The bank lockers are the safest place to protect them, but in recent years, bank robberies are increasing day by day due to traditional methods and security laps. The present bank locking system security is not very efficient and it can be easily breakable by a smart larceners as they can get the key or Personal Identification Number code. The solution to overcome this type of frauds can be met with the proposed two-factor authentication in bank locking security system.

The two factor authentication system is used in Bank Automated Teller Machine transactions and web based login systems such as Google provide the two factor authentication for their online users, and also Facebook, MSN and Yahoo that is evolving technology. The idea of two factor authentication system for bank locker is enabled, to ensure the security and portability of the information or possessions. One-time password and Fingerprint biometric based two factor authentication system will be a solution for above discussed requirement that can be able to eliminate the weaknesses of existing system. In term of security, significant improvement can be provided by this system.

The system will reduce the fraud and misuse by stealing keys, passwords, Personal Identification Number and identification proofs. The system can raise alarm to alert bank staff. In this project, the locker provided with simple and low power consumption solenoid that controls the lock to the locker instead of a key.

The proposed system would overcome the drawbacks of the existing systems and provide high security to bank lockers with the use of two independent authentication methods which are fingerprint biometric and one-time password. When a customer wants to open a bank locker, he/she supposed to get their fingerprint scan done. If the fingerprint matches, the system sends the one-time password to the authentication customer through the registered phone number and required it to type in the locker system. If the entered password by the customer matched, the bank locker could be accessed, otherwise the system sends warning signals and remain in locked status.

The establishment of this bank locking system would reduce time wastage, better use of replacement with double security, reduction in cost of labor, satisfaction for customers, reduction of frauds, easy accessibility and overall better service for customers of the bank.

 1.2      Problem Statement

            Bank lockers play important role in today’s life and it is considered the safest place to store jewelry, documents, stock certificates and etc. The traditional methods used for most banks rely on manual lock and Personal Identification Number number/password which are not fully secure. In manual lock systems, whenever a customer uses the locker, he/she should assist by the bank staff. This may lead to waste of time for both the customer and the staff. The major drawback of such manual locker systems are lack of security because the key can be duplicated. This would lead to theft of the entire valuable possessions in the bank lockers.





1.3        Aim and Objectives

1.3.1    Aim

The aim of this project is to develop a two factor authentication in bank locking security system.

1.3.2     The  Specific Objectives of this project are to:

  1. develop a locker system that can replace the current traditional methods such as manual lock, PIN (Personal Identification Number), and password.
  2. evaluate the security with automated locker system based on two-factor authentication.
  • test the application using testing techniques.

1.4       Justification

The bank locking systems verify and validate users based on two-factor authentication; fingerprints biometric and One Time Password (OTP) sent through global system for mobile communication. In the initial stage, the enrolment takes place where the users fingerprint is scanned, analyzed and then minutiae features will be extracted as a template on a memory to be utilized for future comparism.









1.5       Scope of the Project

The scope of the project is concentrated at two-factor authentication in order to access the Bank locking system. The project is mainly focused on restricting the unauthorized access and alerting in case of theft. The fingerprint biometric and one-time password authentication implemented. The accuracy of fingerprint scanner is depended on fingerprint sensor specification. More accuracy of fingerprint sensor will provide strong finger authentication which cannot be forged. The one-time password depended on method of random number generation. This project will have software, hardware implementation and limitation.
