Recent studies show that online companies will face a variety of digital payment frauds, reaching $48 billion by 2023, up from $41 billion in 2022. Experts believe that AI and ML technologies are powerful tools to address these issues. Fraud is advancing rapidly, surpassing traditional methods of prevention and causing huge financial losses. From phishing emails to deepfake videos, the risk of fraud is everywhere.
AI is predicted to boost productivity in 64% of businesses in the coming years. While human skills remain essential, they need a powerful partner—AI and ML technologies. These tools are known for identifying distinct patterns and features associated with fraudulent actions.
The Role of AI and ML in Fraud Detection: A New Dimension
Artificial Intelligence (AI) imitates human cognitive functions using computer systems, making decisions in a way that resembles human reasoning. It encompasses various concepts, with machine learning (ML) being a key one.
Understanding Artificial Intelligence (AI)
AI, when trained on historical data, can effectively identify fraud. AI and ML provide highly adaptable and effective solutions to combat rising challenges like digital identity theft driven by bots.
With AI-powered systems, a company’s registration process can easily detect and halt suspicious transactions, such as:
- Account Takeovers
- Payment Frauds
- Fake Transactions
AI’s flexible and adaptive nature ensures it continues to evolve, providing robust defenses against emerging threats.
Diving Into Machine Learning (ML)
ML is a subset of AI where systems learn from data without direct human involvement. ML operates through three primary methods:
- Supervised Learning
- Reinforcement Learning
- Unsupervised Learning
What About Deep Learning?
Deep learning is a more specialized area within machine learning, aimed at enhancing automation by developing artificial neural networks that mirror the human brain’s structure.
Unlike basic ML, deep learning excels in managing unstructured data and continuously improves its accuracy using advanced techniques like gradient descent and backpropagation.
How AI and ML Technologies Provide Benefits
AI and ML act as powerful fraud detection tools that identify suspicious actions without subjecting businesses to financial risks. Here’s how these technologies support companies:
- Automating repetitive tasks to save time and effort.
- Analyzing large datasets to help businesses make informed decisions.
- Offering customized services to clients.
- Enhancing overall business efficiency through automation.
Major Types of Fraud Detected by AI
AI plays a critical role in fraud management, as each type of scam requires specific automated tools to detect it.
Tip: The ideal method for detecting a particular type of fraud should depend on its unique characteristics.
Below are the key types of fraud, AI techniques used, and indicators of suspicious activity:
- Payment Fraud: Detected using machine learning (ML) and anomaly detection techniques, highlighted by unusual transactions or location mismatches.
- Impersonation: Identified through pattern recognition and biometric analysis, focusing on forged identities or abnormal transactions.
- Supply Chain Fraud: Detected using anomaly detection and network analysis, with signs like supplier risk factors or incorrect shipments.
- Account Fraud: Uncovered with ML and Natural Language Processing (NLP), identified by inconsistencies or unusual financial activities.
- Policy Abuse: Exposed using data mining and image analysis, indicated by fake claims or overstated incidents.
Watch Out for the Top 3 Digital Threats
The most significant digital identity threats today include:
- Account Botting
Fake accounts are becoming more frequent, making identity theft common online. Facebook reported removing $1.4 million worth of spam content in the third quarter of 2022, showing a surge in fake profiles on social platforms. Botnets create massive networks of fake profiles that connect across different sites. AI and ML technologies can help control this growing issue. - Digital Transaction Scams
Bot networks are often used to crack encrypted data, usually to verify if stolen credit card details are still valid, often through small transactions. - Account Hijacking
Similar to payment fraud, account hijacking involves using techniques like backtracking. Bots use stolen databases to test login credentials, employing methods like rainbow tables, dictionary attacks, and brute force to break passwords.
AI and ML are stepping up as critical players in detecting such scams. They adapt quickly to new forms of fraud, enhancing security systems to fight these emerging threats.
Other types of complex fraud include:
- Financial Frauds
- Money Laundering
- Insurance Scams
How Machine Learning Identifies Complex Frauds: A Step-by-Step Process
Machine learning-based fraud detection is a multi-step process that includes:
- Data Preparation
The first step is collecting and setting up data. Companies feed specific guidelines into AI systems. In supervised learning, labels are needed, while unsupervised learning allows the system to identify patterns in unlabeled data. - Extracting Relevant Information
This step involves focusing on transaction times, methods, amounts, and purchasing patterns. For example, if there are many fake orders resulting in refunds, AI tools can help identify the patterns. Businesses can then access detailed user data like addresses and device information, allowing the AI system to improve its accuracy. - Creating a Fraud Detector
By analyzing provided data, AI and ML models can detect possible fraudulent actions. The set rules during this stage combine multiple factors for more accurate decisions and can be adjusted as needed. - Training and Testing AI
AI systems are trained on historical data to spot suspicious behaviors. This ensures AI and ML tools are well-suited for each business’s specific needs.
