There are several types of data that could be used for an online payment fraud risk model, including:
1. User data: This includes information about the user, such as their name, address, phone number, email address, and IP address. This data can help detect if the user's location and device are consistent with their usual behavior. 2. Transaction data: This includes information about the transaction, such as the amount, date and time, currency, and payment method. This data can help detect if the transaction is consistent with the user's usual behavior and spending patterns. 3. Device data: This includes information about the device used to make the transaction, such as the device type, operating system, browser, and screen size. This data can help detect if the device is consistent with the user's usual behavior and if it has any known vulnerabilities. 4. Behavioral data: This includes information about the user's behavior during the transaction, such as the time taken to complete the transaction, the number of attempts, and any errors or interruptions. This data can help detect if the user is behaving unusually or if there are any technical issues that could indicate fraud. 5. Risk scores and indicators: These are pre-calculated scores or indicators that are generated by fraud prevention systems and third-party providers. These scores and indicators can help detect if a transaction is high-risk based on factors such as the user's location, device, and previous transaction history. 6. Counters: These are specific data points that are used to track and monitor certain activities or events related to the transaction, such as the number of failed login attempts, the number of requests to change the user's password, or the number of times the user has attempted to purchase a particular item. Overall, a combination of these data points can be used to build an effective online payment fraud risk model. However, it is important to balance fraud prevention with user experience and ensure that any measures put in place do not negatively impact legitimate transactions.
