Fraud detection refers to the process of identifying and preventing fraudulent activities, often in financial transactions. It involves analyzing data to spot unusual patterns or behaviors that may indicate deceit, such as credit card fraud or identity theft. Organizations use various techniques, including algorithms and machine learning, to enhance their detection capabilities. Effective fraud detection systems can help businesses save money and protect their reputation. By monitoring transactions in real-time, these systems can flag suspicious activities for further investigation. This proactive approach is essential for maintaining trust in services like banking and e-commerce.
