The processes are to be monitored in real-time to check for fraudulent activities.

Fraud detection techniques

Fraud typically involves many repeated methods by making searching for patterns a general focus for fraud detection patterns and anomalies.

Statistical data analysis techniques include:

  • Calculating statistical parameters
  • Regression analysis
  • Probability distribution and models
  • Data matching

The AI techniques used are listed below

Data mining-

It will classify the group and segment data to search through millions of transactions to find the patterns and also detect fraud.

Machine learning-

It will automatically identify characteristics found in fraud.

Pattern recognition-

It will detect classes, clusters, and patterns of suspicious behavior.

These techniques apply adaptive and predictive analytics to create a fraud risk score along with real monitoring of fraudulent events. It also helps decipher new and sophisticated preventive measures through automation.

Statistical data analysis techniques:

  1. Statistical parameter calculation – Statistical parameter calculation refers to the calculation of various statistical parameters such as averages, quantiles, performance metrics, and probability distributions for fraud-related data collected during the data capturing process.
  1. Regression analysis – Regression analysis allows you to examine the relationships between two or more variables of interest. It also shows the relationship between independent and dependent variables. This helps us to understand and identify relationships between many fraudulent activities.
  1. Probability distributions and models- The models and probability distributions of various business fraudulent activities are mapped whether in terms of different parameters or probability distributions.
  1. Data matching- Data matching is applied for the comparison of two sets of collected data. Algorithms or programmed loop techniques can be used for making such comparisons. The data matching is used to remove duplicate records and identify links between two sets for marketing, security, or other purposes.

Applications of fraud detection:

Fraud Detection is of paramount importance for banks and other companies that deal with a significant number of financial transactions and are therefore at a higher risk of suffering from financial fraud. There are most common applications of fraud detection to include payment and transaction fraud. Account fraud will be further divided into new account fraud and account takeover fraud.
