Solution Overview

Problem

Current access control systems rely on intermediary information sources, such as human resources databases, which increase computational resources and complexity, and are inefficient in validating user credentials, especially in scenarios requiring medical status verification.

Innovation Solution

An access control system utilizing a distributed ledger to validate user credentials, including medical status, by integrating sensors and processors to detect and evaluate sensor data, and updating records on an electronic wallet or distributed ledger, allowing for efficient and secure access control without the need for intermediaries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If intermediary information sources (human resources databases) are used for access control validation, then credential validation can be performed, but computational resources and system complexity increase

Engineering Contradiction:

Improvecredential validation reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the credential validation function from centralized intermediary databases and places it directly on the user's mobile device. The mobile device now independently validates credentials and medical status information, eliminating the need for complex intermediary information sources and reducing overall system complexity while maintaining validation reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a distributed ledger as a new intermediary that provides a simplified, decentralized validation mechanism. Instead of complex human resources databases, the distributed ledger serves as a lightweight mediator that enables credential validation with reduced computational resources and system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by moving object

If distributed ledger technology is implemented for credential validation, then computational resources and bandwidth requirements are reduced, but system implementation complexity increases

Engineering Contradiction:

Improvecomputational resource consumptionVSAvoidimplementation complexity

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The mobile device performs self-service credential validation by independently evaluating medical status information and validating credentials against the distributed ledger. This eliminates the need for complex centralized validation systems, reducing both computational resource consumption and implementation complexity through decentralized automation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The mobile device serves multiple functions: it stores credentials, validates medical status, communicates with sensors, and interacts with the distributed ledger. This multi-functionality consolidates what would otherwise require separate specialized systems, reducing overall implementation complexity while minimizing computational resource requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If medical status evaluation is performed using sensor data and credential data, then access control accuracy is improved, but processing time increases

Engineering Contradiction:

Improvemedical status evaluation accuracyVSAvoidaccess validation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

Medical status information is pre-collected and stored in the mobile device before access validation is needed. Sensors evaluate medical status in advance, and this pre-evaluated information is readily available during access control, eliminating real-time processing delays while maintaining high evaluation accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent combines credential data validation with medical status evaluation into a single integrated process. By merging these two validation steps that would otherwise occur separately, the system achieves accurate medical status evaluation without the time penalty of sequential processing, as both validations occur simultaneously through the distributed ledger mechanism.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An access control system includes a plurality of sensors and an access controller that includes one or more processors. The sensors detect sensor data regarding a user. The one or more processors receive credential data regarding the user from at least one of an access control device and an electronic wallet, evaluate a medical status using at least one of the sensor data and the credential data, validate access into a space responsive to the medical status being satisfied, and update a record data structure of at least one of the electronic wallet and a distributed ledger using the evaluation of the medical status.
