Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Web traffic tracking methods relying on third-party cookies face accuracy issues due to user refusal or deletion, leading to reduced effectiveness in tracking visitor behavior.

Innovation Solution

Implementing first-party cookies instead of third-party cookies for web traffic reporting, using a client-side script to maintain site-maintained visitor IDs and send them to tracking services for analysis, while transitioning from third-party to first-party cookies with cooperation from third-party services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If third-party cookies are used for tracking, then tracking coverage can be achieved, but tracking accuracy deteriorates due to user refusal or deletion

Engineering Contradiction:

Improvetracking accuracyVSAvoidtracking effectiveness

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent uses first-party cookies as an intermediary mechanism to bridge the gap between the website and third-party tracking services. The first-party cookie stores a visitor identifier that is then transmitted to the third-party service, allowing tracking to occur without requiring the user's computer to accept or retain third-party cookies. This intermediary approach resolves the contradiction by maintaining tracking accuracy through first-party cookies while preserving tracking effectiveness through the intermediary transmission mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If third-party cookies are used, then visitor tracking can be implemented, but user privacy perception deteriorates

Engineering Contradiction:

Improvetracking implementationVSAvoiduser privacy concern

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the traditional approach by having the first-party website set and manage the tracking cookie instead of relying on third-party services to set cookies directly. This inversion makes the tracking mechanism transparent and controllable by the website owner, improving user privacy perception while maintaining tracking implementation capability. The first-party cookie is perceived as more legitimate and less intrusive than third-party cookies.

Inventive Principle:

Principle #13The other way round (Inversion)

3Object-affected harmful factors

If first-party cookies are used instead of third-party cookies, then user privacy perception improves, but cross-domain tracking capability deteriorates

Engineering Contradiction:

Improveuser privacy perceptionVSAvoidcross-domain tracking

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent makes the first-party cookie universal by using it not only for single-domain tracking but also as the foundation for cross-domain tracking. The visitor identifier stored in the first-party cookie is transmitted to third-party services that can then associate it with activity across multiple domains. This multi-functional use of the first-party cookie resolves the contradiction by maintaining user privacy perception while enabling cross-domain tracking capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Web traffic reporting methods that rely upon third-party cookies suffer in accuracy when those tracking cookies are frequently refused by web users or deleted once they have been accepted. The invention described herein circumvents this problem by employing first-party cookies instead. This is accomplished by a client-side script that maintains the first-party cookie (as placed by the web site in question) and sends a site-maintained visitor ID to a tracking service for analysis. The effect is to improve the accuracy of traffic statistics that rely on that cookie.
