Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing security systems fail to effectively prevent unauthorized use of identity badges, particularly in automated systems where visual verification is not possible, leading to security breaches.

Innovation Solution

A method that modifies identity badges to ensure the face of the user matches the visual image on the badge, using facial recognition and a database to verify access, and dynamically changes the displayed image or symbol based on the user's location to maintain privacy and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated badge reading systems are used to grant access, then access speed and convenience are improved, but security verification capability deteriorates because visual confirmation of badge-user match is not possible

Engineering Contradiction:

Improveaccess speedVSAvoidsecurity verification capability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent replaces manual visual verification (mechanical/human process) with automated optical recognition systems. Cameras capture images of the badge and user face, then image processing algorithms automatically compare them to verify identity, enabling both fast automated access and reliable security verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary image processing system that acts as a mediator between the badge reader and access control. This intermediary automatically compares the badge image with the user's facial image and verifies identity, resolving the contradiction by providing both automation and verification capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If static badge images are displayed, then user identification is simplified, but privacy and cultural sensitivity requirements cannot be met in different locations

Engineering Contradiction:

Improveuser identificationVSAvoidprivacy and cultural sensitivity adaptation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent makes the badge display dynamic rather than static. The badge image or information displayed changes automatically based on the user's current location, allowing the system to adapt to different privacy and cultural requirements while maintaining simple user identification through consistent badge scanning.

Inventive Principle:

Principle #15Dynamics

AI summary

Confirming access for a user includes capturing an image of the user, capturing information on an identity badge worn by the user, and denying access to a resource in response to the information being inconsistent with the image. Confirming access for a user may also include denying access in response to the information being inconsistent additional information about the user stored in a database. The information may include a picture of the user. The resource may include access to an area. The resource may include access to a computer. Confirming access for a user may also include, following allowing access to the computer, periodically recapturing the image of the user and recapturing the information on the identity badge and denying access to the computer in response to the information being inconsistent with the image. The information may include a visual code that identifies the user.
