The VeriSign® Identity Protection (VIP) Fraud Detection Service (FDS) works in real time to detect and identify theft and transaction fraud. It includes both a rules-based engine and a behavioral engine. Using rules and anomaly detection technology, the service is able to flag potentially fraudulent activities based on known and unknown types of fraud and behaviors not associated with the user. The service is designed to be simple and unobtrusive for both Web administrators and users. If the system detects a suspicious transaction, users can quickly confirm their identities using an automated system. This automated system may query the user to identify themselves further with any of the following types of credentials: a one-time password or security code, a unique question-and-answer, email, SMS, an automated call or a customer service call.

Fraud can be more difficult to prevent for online brokerages and trading firms than it is for other businesses because of the real-time nature of stock transactions. The VIP Fraud Detection Service now includes a Stock Trading Module for Pump and Dump to analyze stock trades in real time after the trade is placed but before it is executed. The unique behavior engine is ideally suited to monitor stock transactions and its associated fraud. The module uses four unique models to determine the risk of each trade. In the event of any anomaly or high risk transaction, the service will flag potentially fraudulent activities and can optionally intervene to validate the transaction using the standard methods such as phone, SMS, Email etc. The VIP Fraud Detection Service Stock Trading Module is the only fraud detection solution that enables online brokerages to analyze stock trades in real time and helps prevent Pump and Dump scams without adversely affecting the user experience.
