Messaging Interface Privacy Shield Triggered by 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, as passcodes can be stolen and screen locks inconvenience users while only protecting device owners, not senders.
Innovation Solution
Implementing a biometric security mechanism that uses facial, ear, silhouette, speaker, or fingerprint 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 is used to lock the screen, then device access is protected, but the passcode can be stolen and transferred to unauthorized users
Solution Approach 1:
The patent replaces the mechanical/passcode-based authentication system with a biometric recognition system. Instead of relying on knowledge-based passcodes that can be stolen, the system uses physiological biometric data (fingerprints, facial features, ear shapes) that are unique to each individual and cannot be transferred or stolen in the same way. This substitution fundamentally changes the security mechanism from something that can be copied to something that is inherently tied to the user's physical identity.
2Reliability
If a screen lock is implemented, then device privacy is protected, but access to other applications is prevented making it inconvenient
Solution Approach 1:
The patent applies different security levels to different applications or message types. Instead of a universal screen lock that blocks all access, the system allows users to configure which applications require biometric authentication and which do not. This local quality approach means that sensitive applications can have enhanced security while less sensitive ones remain easily accessible, resolving the contradiction between privacy protection and operational convenience.
3Reliability
If message destruction scheduling is used, then message privacy is protected after a time period, but the solution does not prevent unauthorized access during the message's active period
Solution Approach 1:
The patent implements preliminary biometric verification before a user can access messages, rather than relying solely on time-based destruction. By requiring biometric authentication as a preliminary action before message viewing, the system ensures that even if messages remain in the system beyond the scheduled destruction time, they cannot be accessed by unauthorized individuals. This layered approach combines time-based privacy with active security verification.
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.
