Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems for accessing secure resources, both physical and network-based, face challenges in providing a secure and privacy-preserving method that effectively combines credential data, voice print identification, and geographic location verification.
Innovation Solution
A method and system that utilize credential data, voice print identification, and geographic location verification through a combination of username/password, encoded cards/tokens, and voice communication, where the geographic location is determined using wireless carriers or location-determination systems, ensuring authorization by matching user profiles and registered locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the authentication system obtains detailed location data from wireless carriers to verify user location, then the security and reliability of authentication is improved, but user privacy is compromised and information loss increases
Solution Approach 1:
The patent extracts only the necessary authentication information (Boolean indication of location match) from the location data, rather than obtaining or storing detailed location information. This allows the system to verify whether the user is at a permissible location without capturing actual location data, thus maintaining authentication reliability while preserving user privacy.
Solution Approach 2:
The patent introduces an intermediary verification process where the wireless carrier provides only a Boolean indication (yes/no) regarding whether the user's location matches a registered location, rather than providing actual location coordinates. This intermediary step acts as a privacy-preserving mediator that enables authentication verification without exposing sensitive location information.
2Reliability
If the system combines multiple authentication factors (credential data, voice print, location), then the security level is improved, but the device complexity and operational difficulty increase
Solution Approach 1:
The patent merges multiple authentication factors (credential verification, voice print analysis, and location verification) into a unified authentication process. The system combines these separate verification steps into a single integrated flow where all factors must be satisfied for authentication to succeed, thereby improving security while maintaining operational simplicity through unified processing.
Solution Approach 2:
The patent creates a multi-functional authentication system that can handle different authentication factors (credentials, voice prints, location data) through a single universal verification process. The authentication server is designed to universally process multiple types of authentication data using the same underlying verification framework, reducing system complexity despite the multiple authentication factors involved.
3Measurement precision
If the authentication system processes and stores detailed user information (credentials, voice prints, location data), then the accuracy of authentication is improved, but the quantity of data stored increases and privacy concerns arise
Solution Approach 1:
The patent extracts only the essential authentication characteristics from user data without storing the complete original information. The system processes detailed data (voice prints, location coordinates) for verification purposes but stores only the necessary identifiers and verification results, minimizing data quantity while maintaining authentication accuracy.
Solution Approach 2:
Instead of storing detailed user information and comparing it during authentication, the patent inverts the approach by storing minimal reference data (registered locations, voice print templates) and performing verification through transformation of the provided authentication factors. This inversion reduces the quantity of stored data while preserving authentication precision.
Data Source
AI summary
An authentication system is described for controlling a person's access to a resource, which may be a physical resource or a network resource. The authentication system obtains credential information for the person (e.g., using a coded card or keypad for username and password), a voice print from the person, and the current geographical location of the user. The voice print and geographic location are preferably obtained from a telephone call that occurs between the person and the authentication system. The call can take the form of a cell phone call placed by the person to the authentication system. The authentication system includes a user profile database. If the credential information and voice print match those of persons authorized to access the resource, and the user is at a registered permissible location to access the resource, the authentication system sends a signal to the resource indicating that the authentication was successful.
