Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The Cost Per Click (CPC) advertising model faces significant challenges due to 'invalid clicks' or 'fraudulent clicks,' which lead to unnecessary costs for advertisers, as it is difficult to prevent 100% of unintentional or malicious clicks, resulting in inefficient cost expenditure.

Innovation Solution

A method and system that verify and associate Internet Protocol (IP) addresses of user terminals generating invalid clicks with advertisements, registering these IP addresses in an invalid click list, and excluding the corresponding advertisements from exposure requests, providing alternative advertisements based on exposure rank.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CPC charging scheme is used to calculate advertising cost based on click, then advertising cost reflects advertising effect, but invalid clicks cause advertisers to expend costs unnecessarily

Engineering Contradiction:

Improveadvertising cost accuracyVSAvoidunnecessary advertising cost

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary verification of IP addresses by analyzing click patterns, geographic consistency, and temporal distribution before charging advertisers. Invalid click patterns are detected and flagged in advance, preventing unnecessary costs from being incurred.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors click data and provides feedback to the charging mechanism. When invalid clicks are detected through pattern analysis, the feedback loop adjusts the charging calculation to exclude these invalid clicks, ensuring accurate advertising cost reflection.

Inventive Principle:

Principle #23Feedback

2Reliability

If system verifies and blocks IP addresses to prevent invalid clicks, then invalid clicks are intercepted, but legitimate ads may be incorrectly blocked

Engineering Contradiction:

Improveinvalid click preventionVSAvoidfalse positive ad blocking

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system changes multiple parameters simultaneously for comprehensive verification: geographic location parameters, temporal distribution parameters, click frequency parameters, and device fingerprint parameters. This multi-parameter approach enables accurate differentiation between invalid and legitimate clicks, reducing false positives while maintaining high invalid click detection rates.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method and system of processing an invalid click is provided. The method includes the steps of: verifying an invalid click Internet Protocol (IP) address of a user terminal generating the invalid click with respect to an advertisement; associating the invalid click IP address with the advertisement, and registering and maintaining the invalid click IP address in an invalid click list when the invalid click IP address is verified; and providing the user terminal of the invalid click IP address with a result page other than the advertisement with respect to an advertisement exposure request using the invalid click IP address. When a number of clicks is greater than or equal to a predetermined number of clicks with respect to the same advertisement using the same IP address over a predetermined time, the step of verifying verifies the same IP address as the invalid click IP address.
