Web Based Project 80

 We here come up with a system to develop a website which has capability to restrict and block the transaction performing by attacker from genuine user’s credit card details. The system here is developed for the transactions higher than the customer’s current transaction limit.  We tried to detect fraudulent transaction before transaction succeed. During registration we take required information which is efficient to detect fraudulent user activity. Here we present a Behavior and Location Analysis (BLA). The details of items purchased in Individual transactions are usually not known to any Fraud Detection System (FDS) running at the bank that issues credit cards to the cardholders. Hence, We implemented BLA for addressing this problem. An advantage to use BLA approach to reduce number of false positive transactions identified as malicious by an FDS although they are genuine. An FDS runs at a credit card issuing bank. Each incoming transaction is submitted to the FDS for verification. FDS receives the card details and transaction value to verify, whether the transaction is genuine or not. The types of goods that are bought in that transaction are not known to the FDS. Bank declines the transaction if FDS confirms the transaction to be fraud. User spending patterns and geographical location is used to verify the identity. If any unusual pattern is detected, the system requires re-verification. Based upon previous data of that user the system recognizes unusual patterns in the payment procedure.  System will block the user after 3 invalid attempts.

Modules and their Description

This system comprises of 2 major modules with its sub-modules:

1. Admin
2. Login: Admin need to login using valid login credentials in order to access the system.
3. Add / View Products: Admin can add new product with its details into the system.
4. View Transactions: System allows admin to view all the transactions done by the registered users.
5. User
6. Registration: Here, user first need to registration themselves with details to access the system.
7. Login: After a successful registration, user then need to login into the system by inputting their credentials into the system.
8. View Products: User can view multiple products with its details. Interested users can purchase a product via online transaction.
9. Buy a Product: User can select payment mode to perform transactions by providing the card details like card no., CVV code, Expiry Date and Holders name.
10. View Transaction: List of all the transactions will be displayed to the user.

Software Requirements:

• Windows 10, Windows 7
• Sql 2008
• Visual studio 2010, Visual Studio 2017

Hardware Components:

• Processor – Dual Core
• Hard Disk – 50 GB
• Memory – 1GB RAM

Advantages of project

• The system stores previous transaction patterns for each user.
• Based upon the user spending ability and even country, it calculates user’s characteristics
• The system is more secured with OTP (One Time Password) implementation.
• IP address tracking at every transaction.
• Security questions for payment limit crossed
• More than 20-30 % deviation of user’s transaction (spending history and operating country) is considered as an invalid attempt and system takes action.

Application

This application can be implemented in banks and e-commerce website.
