Innovation Solution

A dual-layer identification service combining passive biometrics with device identification rules to form a blended response, reducing the number of iterations needed for accurate user identification to two.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If passive biometrics alone are used for user identification, then the identification process is simple, but the number of iterations required is ten or more before accurate identification

Engineering Contradiction:
Improveidentification speedVSAvoidtime for accurate identification
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines passive biometrics with device-based identification rules into a dual-layer identification service. The first layer uses passive biometrics to generate an initial identification, and the second layer applies device-based rules to verify or supplement this identification. This merging of two different identification approaches reduces the total iterations needed from ten or more to just two iterations while maintaining accuracy.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If passive biometrics are used for user identification, then the system is simple to operate, but ten or more iterations are required for accurate identification

Engineering Contradiction:
Improveuser identification processVSAvoididentification efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The identification process is segmented into two distinct layers: the first layer handles passive biometric analysis, and the second layer handles device-based rule verification. This segmentation allows each layer to specialize in its strength while working together to achieve accurate identification in fewer iterations, improving overall efficiency without complicating the user experience.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If only passive biometrics are used, then the identification method is straightforward, but the number of iterations needed increases to ten or more

Engineering Contradiction:
Improveidentification system structureVSAvoidtime to accurately identify user
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system performs preliminary identification using passive biometrics in the first layer, generating an initial assessment before applying the second layer of device-based rules. This preliminary action allows the system to quickly narrow down identification possibilities, reducing the total time and iterations needed for accurate identification while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #10Preliminary action

AI summary

User identification with blended response from dual-layer identification service. In one embodiment, a server comprising an electronic processor configured to detect an access request by a user of a user interface device, retrieve a plurality of input profile records from an input profile record repository, perform an identification of the user with one or more passive biometrics models and the plurality of input profile records that are retrieved, generate an identification response and an additional identification request based on an outcome of the identification of the user, control the communication interface to transmit the additional identification request to the second server via the network, receive a second identification response from the second server, and generate a blended response by modifying one or more characteristics of the identification response with the second identification response, the blended response indicating the identification of the user.
