Abstract- Internet has revolutionized the way we live.

Banking sector have largely grown in popularity and so now user has started online banking. But this revolution, even though it has paved a greater way to help people ,has more number of risks and security flaws that will in turn affect the users who are common people and retrieve confidential information about them and try to attack especially in the field of online banking. So to avoid all these we have planned to implement and develop applications in such a way that it provides secured transactions from unauthorized users and hackers. In early days people used textual password to protect their information from hackers but still these passwords get affected due to various attacks like shoulder surfing ,phishing and dictionary attack etc...In our concept we are going to provide security in login phase instead of transaction so that the hackers will be sorted out in the phase of login itself. In phase of login users will be provided a set of secret question which can be only answered by the authorized users so unauthorized will be sorted out and further cannot proceed for the transaction phase. This technique becomes more beneficial since security is provided in the login phase itself.

data are accessible on the card itself. These days, bank is additionally asking for to enrol your MasterCard for online secure secret word. In this new model, subsequent to sustaining points of interest of card at shipper site, then it will exchange to a safe door which is built up at bank’s own server. In any case, it is not checking that the exchange is fake or not. On the off chance that programmers will get secure code of charge card by phishing locales or whatever other source, then it is exceptionally hard to follow false exchange.

1.2 LIMITATIONS 

Simply using a user ID and password combination for login security is no longer for safe method for protecting your user accounts and preventing unauthorized access by attackers.



Brute force attacks, phishing, and malware can easily defeat this outdated login method, but twofactor authentication adds an additional layer of security that helps prevent unauthorized access by requiring the user to verify identity through a separate method that is often inaccessible to attackers.



These intruders or hackers will be present all over the internet and causes major problems like stealing the money, sending the virus to access the accounts ,OTP Can be easily hacked

Keywords: shoulder surfing, phishing, secret question, dictionary attack.

1. INTRODUCTION In today’s universe of rising advancements, endeavors are moving towards the Internet for organizations.

Individuals are surging towards the e- business applications for their day-today needs, which are making the Internet exceptionally prevalent. Online Banking has given both an open door and a test to conventional saving money. In the quickly developing world, banking is a need, which takes a ton of time from our occupied plan. Heading off to a branch or ATM or paying bills by paper look at and mailing them, and adjusting check books are unequalled expending errands. Saving money online mechanizes a considerable lot of these procedures, sparing time what’s more, and cash. For all banks, internet managing an account is a capable apparatus to increase new clients while it serves to dispense with expensive paper taking care of and manual teller connections in an inexorably aggressive keeping money environment. Banks have spent eras picking up trust of their clients. So there is a need to provide a high level of security in online banking.

1.1 EXISTING METHOD: In existing models, the bank is checked charge card data, CVV number, Date of expiry and so forth. Yet all these © 2018, IRJET

2. PROPOSED SYSTEM Worldwide n number of online banking transactions takes place in the internet. With the development of secure authentication during transactions in most of the popular banking system chances of fraud associated with it is also rising. The proposed system main objective is to effectively detect fraud because of its two levels of security which is used before carrying out the transaction. Secret question is fascinating technology which enables only the authenticated user can have a access over it. To implement these strategies we use Time based One Time Password Algorithm.

2.1. ADVANTAGES 

Security in net banking is a challenging criterion as the people does not know what is happening in the background. This system can eliminate the fraud in the initial stage itself.



By using the secret question technology can investigate further regarding the suspicious fraudulent transaction.



So we can expect high level of security in online banking.

AUTHENTICATION: Authentication is a process in which the credentials provided are compared to those on file in a database of authorized users’ information on a local operating system or within an authentication server. The act of logging in to a database, mobile device, or computer, especially a multiuser computer or a remote or networked computer system consist of username and password that allows a person to log in to a computer system, network, mobile device, or user account.

BLOCK DIAGRAM DESCRIPTION 3.1 MODULES The modules used are as follows    

REGISTRATION MODULE AUTHENTICATION MODULE SECRET QUESTION MODULE KEY GENERATION MODULE

REGISTRATION MODULE: This module collects some sort of credentials (such as a username or e-mail address, and a password) to the system in order to prove their identity: this is known as logging in.

Systems intended for use by the general public often allow any user to register simply by selecting a register or sign up function and providing these credentials for the first time.

Registered users may be granted privileges beyond those granted to unregistered users. Net banking services consist two ways in registering like retail user and corporate user which differs functionalities of using online transaction.

SECRET QUESTIONS: An internet security question is a backup measure used to authenticate the user of a website or an application in the event that they have forgotten their user name and/or password. Theoretically, a security question is a shared secret between the user and the website. Many security questions have answers that can easily be found online with just a little research, they are often criticized for making user accounts vulnerable to attack. A security question should not include any information readily available on social media websites, while remaining simple, memorable, difficult to guess, and constant over time

4. CONCLUSION

KEY GENERATION: The Email OTP authentication method sends an email to your email address with a one-time password (OTP). You can use this OTP to authenticate within a certain time frame.

A one-time password (OTP) is an automatically generated numeric or alphanumeric string of characters that authenticates the user for a single transaction or session. An OTP is more secure than a static password, especially a usercreated password, which is typically weak. that although the components were individually satisfaction, as shown by successfully unit testing, the combination of components is correct and consistent. Integration testing is specifically aimed at exposing the problems that arise from the combination of components.

Internet Banking is offering its customers with a wide range of services, customers are able to interact with their banking accounts as well as make financial transactions from virtually anywhere without time restrictions. in order for electronic banking to continue to grow ,the security and privacy aspects need to be improved with the security and privacy issues resolved the future of electronic banking can be very prosperous. the future of electronic banking will be a system where users are able to interact with their banks This paper describes current online banking problems and discusses the need for security testing for online banking, the introduction of secret question at the phase of login will sort out the hackers and unauthorized users. Thus our proposal provides a two level security minimizing the chance of misuse by hackers.
