online transaction fraud detection using backlogging on e-commerce website

175

ABSTRACT

Transaction fraud imposes serious threats to e-commerce shopping. As the online transaction is becoming more well known the types of online transaction frauds associated with this are likewise rising which affects the money related industry. This fraud detection system has the ability to restrict and hinder the transaction performed by the attacker from a genuine user’s credit card details. To overcome these problems, this system here is developed for the transactions higher than the customer’s current transaction limit. During registration, we take the required data which is efficient to detect fraudulent user action. The details of items purchased by any Individual transaction are generally not known to any Fraud Detection System (FDS) running at the bank that issues credit cards to the cardholders. BLA (Behavior and Location Analysis) is implemented for addressing this problem. A FDS runs at a credit card giving bank. Each approaching 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 products that are purchased in that transaction are not known to the FDS. The bank declines the transaction if FDS affirms the transaction to be a fraud. User spending patterns and geographical area is used to verify the identity. In the event that any surprising pattern is detected, the system requires re-verification. Based on previous information of that user, the system recognizes uncommon patterns in the payment procedure. After 3 invalid attempts, the system will hinder the user.

Background

Information mining involves the use of complicated information investigation instruments to discover previously obscure, substantial patterns and relationships among large informational indexes. These apparatuses can include mathematical calculations, factual models, and machine learning methods, (for example, Neural Networks or Decision Trees). Consequently, information mining comprises more than the collection and management of information, it likewise includes investigation and prediction. Information mining can be performed on information represented in textual, quantitative or multimedia structures. Information mining applications can use a range of parameters to observe the information. This includes an affiliation, characterization, sequence or way examination, clustering, and forecasting. When utilizing typical measures, detection of credit card fraud is a dubious errand. Therefore, the development of the credit card fraud detection model has become a lot of significant, whether in the academic, association, or business network recently. Proposed models or existing models are generally insights driven or Artificial Intelligent-based (AI), which have the theoretical advantages in not forcing counterfeit suspicions on the information variables.

Scope

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.

Advantages

  • 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.
