Mobile Device User Authentication via Challenge Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack an efficient method for authenticating users before exchanging information, particularly in social applications, which can lead to incorrect data transfer and security concerns.
Innovation Solution
A system that allows mobile devices to authenticate users by generating a unique token, accessing known information, and confirming identities through a social networking server, using location data, social connections, and challenge questions to ensure accurate information sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If mobile devices exchange information directly without authentication, then information transfer speed is improved, but security and accuracy deteriorate
Solution Approach 1:
The system performs authentication actions before information transfer by having the receiving device send a challenge question to the sending device, which then verifies the sender's identity against stored information before allowing data exchange. This preliminary authentication step ensures reliability without significantly delaying the subsequent fast information transfer.
2Reliability
If manual authentication methods are used, then security is improved, but operation complexity increases
Solution Approach 1:
The authentication system operates automatically by having devices exchange challenge questions and verification data without requiring manual user intervention. The sending device automatically sends challenge questions, receives responses, verifies identities using stored information, and controls the information transfer process autonomously, making secure authentication as simple as initiating the connection.
3Measurement precision
If authentication verification is performed thoroughly, then authentication accuracy is improved, but processing time increases
Solution Approach 1:
The system uses a balanced approach by implementing a challenge question verification mechanism that provides sufficient authentication accuracy without excessive verification steps. The sending device sends challenge questions that require specific responses based on stored user information, providing adequate verification security while keeping the process efficient and not overly time-consuming.
