Dedicated Browser Session Security via Biometric Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and methods to prevent data breaches and loss in distributed workforces, particularly from internal and external threats, while ensuring compatibility with various computing environments and operating systems, and accessibility for non-technical users.
Innovation Solution
The implementation of a dedicated browser restricted to accessing a predefined set of webpages, which monitors the physical presence of the user using a camera and biometric information, and communicates authentication status to third-party systems for multi-factor authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated browser restricted to predefined webpages is used, then security is improved, but device complexity increases
Solution Approach 1:
The browser is segmented into a dedicated restricted browser for secure access and a separate camera system for security monitoring. The restricted browser can only access predefined webpages through proxy servers, while the camera system independently monitors user presence. This segmentation allows each component to be optimized for its specific function without compromising the other.
Solution Approach 2:
A camera system acts as an intermediary between the user and the secure session. The camera continuously captures images and transmits them to a server for analysis, which then determines whether the user is physically present. This intermediary layer adds security without requiring the browser itself to become more complex.
2Reliability
If continuous monitoring of user presence is implemented, then security is improved, but loss of time increases
Solution Approach 1:
The camera system continuously captures images of the user throughout the entire secure session without interruption. This continuous monitoring ensures that security is maintained at all times while the system efficiently processes images in real-time, minimizing delays in detecting user absence.
Solution Approach 2:
The system implements feedback by continuously analyzing camera images and providing real-time information about user presence to the secure session management system. When the user is detected as absent, the system immediately terminates the session, creating a closed-loop security mechanism that responds dynamically to user presence conditions.
3Reliability
If biometric authentication is used, then security is improved, but ease of operation decreases
Solution Approach 1:
The biometric authentication system operates autonomously without requiring manual intervention. The camera automatically captures images, the server automatically analyzes them to determine user presence, and the system automatically enforces security policies. This self-service approach maintains high security while minimizing the operational burden on users.
Solution Approach 2:
Manual authentication methods (such as passwords or physical access cards) are replaced with automated biometric verification using camera-based image recognition. This substitution eliminates the need for users to manually provide authentication credentials while maintaining or improving security through automated physiological verification.

AI summary
Systems and methods are described for providing secure computer sessions using a dedicated browser. The dedicated browser is restricted to accessing a predefined set of one or more webpages. The dedicated browser accesses a respective webpage of the predefined set of one or more webpages through a respective proxy server of a set of one or more proxy servers. While accessing the respective webpage through the set of one or more proxy servers, the dedicated browser monitors whether a specified user is physically adjacent to the computer system using the camera and biometric information for the specified user. In accordance with a determination that the specified user is not physically adjacent to the computer system, the dedicated browser takes a remedial action (e.g., terminates access to the respective webpage).
