Biometric Authenticated Content for Secure Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current messaging systems lack the ability to biometrically authenticate individual messages to specific users, rather than just the device owner, especially in group message settings, leading to unauthorized access.
Innovation Solution
A method that uses biometric authentication, such as fingerprints, voice prints, or facial features, to verify the identity of message recipients, ensuring that only authorized individuals can view confidential communications, which are displayed only as long as the biometric authentication is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is implemented for message access, then message security and privacy are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces a biometric authentication intermediary layer between the message storage system and the message display system. This intermediary verifies user identity through biometric identifiers (fingerprint, voice, facial recognition) before allowing message access, thereby enhancing security without fundamentally altering the core messaging infrastructure.
Solution Approach 2:
The system performs preliminary biometric authentication before message display is enabled. The authentication check is conducted in advance, and only after successful verification is the message content made accessible to the user interface, preventing unauthorized access before it can occur.
2Reliability
If continuous biometric verification is required for message display, then message security is improved, but ease of operation deteriorates
Solution Approach 1:
Instead of requiring continuous biometric verification, the system implements periodic authentication checks at defined intervals during message viewing. The biometric sensor periodically re-verifies user identity, balancing security requirements with user convenience by not demanding constant authentication interaction.
Solution Approach 2:
The authentication requirement dynamically adjusts based on message sensitivity levels and viewing context. Less sensitive messages may require only initial authentication, while highly sensitive content triggers more frequent verification demands, adapting the security burden to the actual risk level.
3Reliability
If biometric authentication fails or is discontinued, then unauthorized access is prevented, but message accessibility deteriorates
Solution Approach 1:
The system implements temporary message instances that exist only for the duration of successful biometric authentication. When authentication fails or is discontinued, the message content automatically expires and is discarded, ensuring that even if unauthorized access occurs, the window for exploitation is extremely limited.
Solution Approach 2:
The system pre-prepares countermeasures against unauthorized access by automatically hiding or deleting message content when biometric verification fails. This preliminary anti-action is built into the authentication logic, so that failed verification immediately triggers security measures without requiring additional user intervention or system configuration.
Data Source
AI summary
A method for biometric authentication has the steps of sending a confidential communication to an intended recipient through the system, the intended recipient providing one or more biometric identifiers to view the communication, wherein the one or more biometric identifiers are unique to the intended recipient, the system verifying the one or more biometric identifiers against one or more stored biometric identifiers, the system accepting the one or more biometric identifiers further has the steps of the system displaying the confidential communication on the mobile device, and the user continues to provide the one or more biometric identifiers, the system continuously verifying the one or more biometric identifiers while the communication is displayed wherein when the verification is uninterrupted of fails the communication is hidden.
