Pay-Per-Click Fraud Protection via Link Randomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pay-per-click fraud is prevalent in the e-marketing industry, where host sites automate clicks to increase revenue and competitors artificially inflate marketing costs by simulating clicks, leading to illegitimate payments and reduced visibility for marketed sites.
Innovation Solution
A pay-per-click data processing system with link randomization logic that modifies link addresses periodically and includes a counter to challenge fraudulent clicks, ensuring only human-verified interactions are recorded and compensated, using a pay-per-click engine coupled with a host and marketed site, and a clock to implement time-based randomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated click selection is used to increase revenue for host sites, then revenue increases, but fraud increases leading to illegitimate payments
Solution Approach 1:
The patent applies dynamics by making the link address changeable over time through randomization. The link address is not fixed but dynamically updated, which prevents automated scripts from capturing and reusing the same link for fraudulent clicks. This dynamic modification ensures that each click must be verified against the current link address, thereby maintaining payment legitimacy while allowing revenue generation through legitimate user interactions.
2Productivity
If automated click selection is used by competitors to inflate marketing costs, then marketing costs increase, but visibility for marketed sites is reduced
Solution Approach 1:
The patent implements feedback mechanisms where the system monitors and verifies each click against the current link address. The pay-per-click engine receives feedback about click attempts and compares them against the dynamically generated link address. This feedback loop enables the system to distinguish between legitimate clicks and fraudulent automated clicks, ensuring accurate measurement of genuine user interactions and preventing inflated marketing costs from fraudulent activities.
3Device complexity
If link address is made fixed for simplicity, then system complexity is reduced, but fraud detection capability is weakened
Solution Approach 1:
The patent applies parameter changes by modifying the link address parameter over time through randomization. Instead of using a fixed link address, the system changes the link address parameter periodically or on-demand. This parameter change creates a moving target that automated fraud scripts cannot predict or exploit, thereby enhancing fraud prevention capability while maintaining reasonable system complexity through programmatic implementation of the randomization logic.

AI summary
Embodiments of the invention provide a fraud prevention method for a pay-per-click data processing system. The method can include receiving a click through for a link in a host site which references a marketed site. The method also can include identifying a link address for the link in the click through. The method yet further can include comparing the identified link address to a modified link address recorded for an actual link address for the marketed site. Finally, the method can include quashing the click through if the identified link address is not the modified link address. Conversely, the method can include redirecting the click through to the marketed site if the identified link address is the modified link address.
