Biometric Signature Encryption for Electronic Document Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication technologies, such as signature-based and PIN-based systems, face reliability issues due to the potential for forgery and compromise, particularly in electronic transactions.
Innovation Solution
Implementing a method that encrypts user signatures or PINs using biometric authentication, creating a dependency where biometric verification is required for authentication, thereby enhancing the reliability of the authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signature-based authentication is used, then user identification is enabled, but the authentication reliability deteriorates due to potential forgery
Solution Approach 1:
The patent introduces biometric authentication as an intermediary layer between the signature verification and the actual authentication decision. The biometric sensor captures physiological characteristics (fingerprint, iris, or facial recognition) that serve as a mediator to verify the user's identity before allowing signature validation, thereby preventing forgery while maintaining ease of use
Solution Approach 2:
The authentication system combines multiple authentication factors (biometric characteristics and signature) into a composite authentication mechanism. This multi-factor approach creates a more secure system where both biometric verification and signature validation must succeed, eliminating the vulnerability of single-factor authentication while preserving user convenience
2Reliability
If PIN-based authentication is used, then user identification is enabled, but the authentication reliability deteriorates due to potential compromise
Solution Approach 1:
The biometric sensor acts as an intermediary that verifies the user's physical identity before allowing PIN entry or validation. This additional layer ensures that even if a PIN is compromised through observation or guessing, the attacker cannot access the system without the corresponding biometric characteristic
Solution Approach 2:
The system creates a composite authentication mechanism combining biometric verification with PIN validation. This multi-factor approach ensures that both the biometric characteristic and the PIN must be correct, significantly increasing the difficulty of compromise while maintaining ease of use for legitimate users
