Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for validating a person's identity, particularly by law enforcement officers during traffic stops, involve physical proximity, which increases the risk of injury and misunderstandings, and lack effective remote identification solutions.

Innovation Solution

A system utilizing voice-print and facial recognition technologies, integrated with cloud-based and mobile technologies, allows for remote electronic identification and verification by comparing voice and facial biometrics against a cloud database, enabling identification without physical contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If law enforcement officers use physical proximity to validate a person's identity during traffic stops, then they can directly examine identification and confirm identity, but the risk of injury to officers and individuals increases

Engineering Contradiction:

Improveidentity validation reliabilityVSAvoidrisk of injury

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces voice-print biometrics as an intermediary mechanism for identity verification. Instead of direct physical confrontation, officers use voice recognition technology to verify identity remotely. The voice-print serves as a mediator that confirms identity without requiring the officer to be in close physical proximity to the individual, thus maintaining reliability while reducing injury risk.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical approach of physical ID examination with biometric voice recognition. The traditional method involves physically approaching someone, requesting ID, and manually examining documents. This is substituted with a system that captures voice prints, compares them against database records, and confirms identity electronically, eliminating the need for physical proximity and reducing harmful factors.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If law enforcement officers follow rigorous multi-step safety procedures during traffic stops, then the risk of injury is reduced, but valuable working time and the person stopped's time are consumed

Engineering Contradiction:

Improverisk of injuryVSAvoidworking time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-registering voice-print biometrics in a database during the driver's license application process. This preliminary collection and storage of biometric data eliminates the need for time-consuming on-site verification procedures. When a traffic stop occurs, the officer can quickly capture and compare the voice print against the pre-stored record, maintaining safety while significantly reducing the time consumed during the actual stop.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service identity verification through automated voice-print comparison. The biometric system automatically captures the voice, compares it against the database, and provides verification results without requiring manual document examination or lengthy procedural steps by the officer. This automation maintains safety protocols while minimizing time loss during traffic stops.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If law enforcement officers assume a presumptive mindset of suspicion to ensure safety during close proximity encounters, then personal safety is prioritized, but misunderstandings and potential assaults increase

Engineering Contradiction:

Improvepersonal safetyVSAvoidpotential for misunderstandings and assaults

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical and psychological approach of close physical confrontation with biometric verification technology. By substituting direct human interaction with automated voice-print recognition, the system maintains officer safety without requiring a presumptive mindset of suspicion. The objective biometric data provides definitive identification information, reducing subjective judgments and potential misunderstandings that could lead to assaults.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A system and method for remote identification of a person includes the steps of contacting the person using contact information provided from a database or utilizing information received from the person via a message broadcast using GPS-fencing. After contacting the person, receiving current biometric information from the person and confirming the identification of the person when the current biometric information is recognized by comparing the current biometric information to the previously collected biometric information of the person in the database.
