Addressing Click Fraud in Content Delivery Systems

—Mechanisms for data access and payment are central to the success of content delivery systems. However, not much attention has been paid to the issues of dishonest intermediaries (brokers) or client collusion with dishonest brokers. We propose protocols to verify broker honesty for data accesses under standard security assumptions in such systems. Analytical and experimental results show that our protocols are robust against replay and fabrication attacks, and are consistently able to identify broker dishonesty.
