Dynamic OS Component Hydration via API Interception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating systems often ship with unused features and API components that waste memory and expose devices to security risks, as they are not dynamically removable or updatable based on application requirements.
Innovation Solution
Implementing an API intercept layer, a rules engine, and a dehydrate/hydrate engine to dynamically add or remove operating system components based on application usage, allowing for a minimal initial deployment with components streamed or rehydrated as needed from local, network, or cloud sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complete operating system image with all features is deployed on a computing device, then application compatibility and functionality are ensured, but memory usage increases and the attack surface is enlarged
Solution Approach 1:
The operating system is segmented into mandatory core components and optional feature components. The mandatory portion contains essential functionality required for all applications, while optional features are divided into separate components that can be selectively loaded. This segmentation allows the system to maintain a minimal memory footprint while preserving full application compatibility when needed.
Solution Approach 2:
The operating system transitions from a static complete image to a dynamic modular structure. Components can be dynamically loaded into memory when required by applications and unloaded when no longer needed. This dynamic approach allows the system to adapt its memory usage based on actual application requirements rather than pre-loading all possible features.
2Adaptability or versatility
If a complete operating system image with all features is deployed on a computing device, then application compatibility is ensured, but the attack surface is enlarged exposing the device to security risks
Solution Approach 1:
Potentially vulnerable optional features are extracted from the mandatory core operating system image. These extracted components can be selectively loaded only when required by specific applications, rather than being permanently present in the system. This extraction reduces the persistent attack surface while maintaining the ability to support diverse applications when needed.
Solution Approach 2:
The system implements dynamic loading of optional components that may have security implications. Instead of having all features permanently installed and potentially exploitable, the system loads these components only when an application actually requires them. This dynamic approach minimizes the attack surface at any given moment while preserving full functionality when needed.
3Quantity of substance
If a minimal operating system image is deployed on a computing device, then memory usage is reduced and security is enhanced, but application compatibility may be compromised
Solution Approach 1:
The system performs preliminary analysis of application requirements before executing applications. When an application is launched, the system analyzes its manifest or configuration to determine which optional components it requires, then pre-loads those specific components into memory. This preliminary action ensures that the minimal core image remains in place for security and memory efficiency, while required functionality is made available on-demand.
Solution Approach 2:
An intermediary component manager is introduced between the minimal operating system core and applications. This intermediary intercepts application execution requests, determines which optional components are needed, loads them from storage or network sources, and manages their lifecycle. This intermediary layer transparently handles the complexity of component management while allowing applications to run on a minimal base system.
4Quantity of substance
If operating system components are dynamically added and removed based on application requirements, then memory efficiency and security are improved, but system complexity increases
Solution Approach 1:
Applications provide self-information through manifests or configuration files that declare their required components. The operating system's component manager reads this self-provided information and automatically loads only the necessary components without requiring complex analysis or user intervention. This self-service approach simplifies the complexity management by leveraging information already available from the applications themselves.
Solution Approach 2:
The system implements feedback mechanisms where applications declare their requirements and the component manager adjusts the loaded components accordingly. This feedback loop allows the system to automatically optimize its configuration based on actual application needs rather than using complex predetermined configurations or requiring manual system administration.

AI summary
Systems, computer program products and computer program products for facilitating the dynamic addition and removal of operating system components on computing devices based on application or user interaction over time are disclosed. Such systems, computer program products and computer program products provide one or more API intercept layers, a rules engine and a hydrate engine that facilitates the ability to dynamically rehydrate or hydrate operating system components. In an embodiment, a minimal (or core) operating system image on a computing device is deployed. Then, required components may be dynamically added (i.e., “streamed” or “rehydrated”) from storage, a server or cloud service as required by an executing application program on the computing device. In another embodiment, a totally complete operating system image is deployed on a computing device. Then, unused components may be dynamically removed (i.e., “dehydrated”) from the computing device over time based on application or user interaction.
