Messaging Interface Privacy Shield Using Recipient Biometrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional messaging systems lack effective security measures to protect the privacy and security of message senders, relying on transferable passcodes and screen locks that are inconvenient and do not adequately prevent unauthorized access or impersonation.
Innovation Solution
Implementing a biometric security mechanism that uses facial recognition, ear recognition, silhouette recognition, speaker recognition, fingerprint recognition, and device motion pattern recognition to verify authorized identities of message senders, ensuring privacy settings are maintained through customizable privacy shields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a passcode-based screen lock is used to protect message privacy, then security against unauthorized access is improved, but convenience of operation deteriorates due to transferable credentials and access restrictions
Solution Approach 1:
The patent replaces the mechanical/passcode-based authentication system with a biometric recognition system. Instead of relying on transferable passcodes that compromise both security and convenience, the system uses unique biological characteristics (facial features, fingerprints, iris patterns) that are inherently non-transferable. This substitution resolves the contradiction by providing both strong security (biometric uniqueness) and convenience (automatic recognition without manual code entry).
Solution Approach 2:
The biometric recognition system enables self-service authentication where the user's own biological characteristics automatically verify their identity. The system captures biometric data from the user and compares it against stored templates, eliminating the need for external authentication intermediaries or manual code verification. This self-verifying mechanism simultaneously improves security (personalized authentication) and convenience (seamless access).
2Reliability
If biometric recognition is implemented to verify message sender identity, then security and accountability are improved, but device complexity increases
Solution Approach 1:
The patent leverages the universality of biometric recognition technology that already exists in modern mobile devices for screen unlocking and app authentication. By reusing this existing biometric infrastructure for message sender verification, the system avoids adding significant complexity while achieving enhanced security. The same camera, sensor, and processing components serve multiple authentication purposes.
Solution Approach 2:
The patent merges the message authentication function with the existing device biometric authentication system. Instead of creating a separate verification mechanism, the system integrates message sender verification with the device's native biometric recognition capabilities. This consolidation achieves identity verification without proportionally increasing device complexity, as the same hardware and software components handle both device access and message authentication.
Data Source
AI summary
Some embodiments include a method of providing security and privacy for a message sender. The method can include a messaging application determining that a messaging interface of the computing device is active and is revealing or about to reveal the electronic message. The messaging application can identify a recipient account of a messaging server system that is associated with the electronic message according to the electronic message or the messaging server system. The messaging application can then monitor a data feed from a sensor of the computing device to detect a biometric pattern that matches against a biometric profile model associated with the recipient account utilizing a biometric recognition process. In response to determining that the detected biometric pattern does not match the biometric profile model associated with the recipient account, the messaging application can activate a privacy shield to prevent content of the electronic message from being revealed.
