Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing audience measurement techniques face challenges in accurately determining Internet media impressions due to limitations in server log monitoring, such as over-counting and under-counting, and the inability to access demographic data from external database proprietors without compromising privacy or violating technical restrictions.

Innovation Solution

Implementing beacon instructions that redirect client browsers to partnered database proprietors to map audience measurement entity (AME) cookies to partner cookies, allowing for demographic information sharing and reducing the need for repeated redirects, thereby enhancing data accuracy and panel size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If server log monitoring is used to track Internet media impressions, then implementation is simple, but measurement precision deteriorates due to over-counting and under-counting errors

Engineering Contradiction:

Improveimplementation simplicityVSAvoidimpression counting accuracy

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent introduces an audience measurement entity as an intermediary that receives data from multiple database proprietors and aggregates it to determine media impressions. This intermediary approach allows for more accurate measurement by combining data from multiple sources (servers, databases) while maintaining system simplicity through centralized processing.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent merges data from multiple sources including server logs and external database proprietors into a unified impression count. By combining these data sources through the audience measurement entity, the system achieves more accurate measurement precision while maintaining ease of implementation through automated aggregation processes.

Inventive Principle:

Principle #5Merging (Combining)

2Measurement precision

If demographic data is collected from external database proprietors, then measurement precision improves, but privacy protection and technical restrictions are violated

Engineering Contradiction:

Improvedemographic data accuracyVSAvoidprivacy violation and technical restriction breach

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The audience measurement entity serves as a mediator that requests demographic information from database proprietors through controlled interfaces. This intermediary role enables the system to access accurate demographic data while maintaining privacy protection by processing data centrally and only accessing information that is legitimately shared with the measurement entity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by establishing agreements and data sharing protocols with database proprietors before collecting demographic information. This preliminary setup ensures that data collection complies with privacy restrictions and technical agreements, allowing accurate demographic measurement without violating constraints.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple redirects are performed to access partner data, then data accessibility improves, but network congestion and processing requirements increase

Engineering Contradiction:

Improvedata accessibilityVSAvoidnetwork congestion and processing load

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent implements a system where the audience measurement entity continuously receives and processes data from database proprietors through established data sharing agreements. This continuous data flow eliminates the need for multiple repeated redirects, as the measurement entity maintains ongoing access to partner data through pre-established channels.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

Data sharing agreements and access channels are established in advance between the audience measurement entity and database proprietors. This preliminary setup enables direct and efficient data access without requiring multiple redirects during actual data retrieval operations, thereby reducing network congestion and processing requirements.

Inventive Principle:

Principle #10Preliminary action

AI summary

An example method includes accessing a network communication at a database proprietor server, the network communication including one or more audience measurement entity cookie identifiers associated with one or more audience measurement entity cookies, the one or more audience measurement entity cookies from an audience measurement entity server and stored in a client device; generating one or more cookie mappings of the audience measurement entity cookies to respective one or more database proprietor cookies, the one or more database proprietor cookies from the database proprietor server and stored in the client device; and causing transmission of one or more re-direct messages to cause the client device to send the one or more cookie mappings in a batch to the audience measurement entity server, a re-direct message of the one or more re-direct messages including a first database proprietor cookie identifier and a first audience measurement entity cookie identifier.
