Whitelist-Authenticated OS Image for Controlled Interactive Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in securing two-way interactive services by identifying and blocking unauthorized software applications, particularly in unmanaged end-user environments, leading to potential data breaches and cheating in scenarios like online exams.
Innovation Solution
A whitelist-based approach using a bootable resource with a secure, read-only OS that includes a chain of trust, denying access to all unauthorized software and limiting network connections to only essential services, ensuring a controlled environment for interactive services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blacklist approach is used to block unauthorized software, then security is improved to some extent, but the system complexity increases and unauthorized software can still evade detection
Solution Approach 1:
The patent inverts the traditional blacklist approach by implementing a whitelist system. Instead of trying to block all unauthorized software (blacklist), the system only allows pre-approved software to run (whitelist). This is achieved through a secure bootable resource that contains an operating system image with predetermined allowed applications, fundamentally reversing the security paradigm from reactive blocking to proactive permitting.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the bootable resource with an operating system image that contains only approved applications and services before the system is used. The whitelist of permitted software is established in advance during the creation of the bootable resource, eliminating the need for real-time detection and blocking of unauthorized software during system operation.
2Reliability
If comprehensive software monitoring and blocking is implemented, then security is improved, but the ease of operation deteriorates due to restricted access
Solution Approach 1:
The system inverts the access control model by defaulting to permission granted rather than permission denied. Users gain immediate access to pre-approved applications without needing to request permissions or navigate complex security protocols. The whitelist approach ensures that legitimate user needs are met while maintaining security, eliminating the operational friction caused by overly restrictive monitoring systems.
3Reliability
If traditional security measures are used in unmanaged environments, then some security is achieved, but data breaches and cheating can still occur
Solution Approach 1:
The patent implements preliminary action by embedding security controls directly into the bootable resource before it is used in unmanaged environments. The operating system image is created with a predetermined whitelist of allowed applications, and the system is configured to only execute these approved applications. This pre-configured approach ensures that even in unmanaged environments where users have physical access to devices, they cannot install or run unauthorized software that could lead to data breaches or cheating.
Solution Approach 2:
The bootable resource acts as an intermediary layer between the user and the underlying hardware. It provides a controlled environment that mediates all software execution requests, allowing only pre-approved applications to run while blocking all other software. This intermediary layer effectively neutralizes security threats in unmanaged environments without requiring complex real-time monitoring or user intervention.

AI summary
Systems and methods of the disclosure provide for receiving, from a GUI on a client device, a request to download and install an OS image and integrated interactive service on a bootable resource; transmitting to the client device the OS image and the integrated interactive service to be installed on the bootable resource, wherein the bootable resource is configured to: on a restart of the client device, boot to the OS image and launch the interactive service; and deny access to any software, service, or resource not available on the bootable resource.
