Sandbox Web Browser Control for Secure Content Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for parsing website content fail to maintain high security and synchronicity with frequent website updates, especially in dynamic environments, and struggle with customization and malware detection.
Innovation Solution
A sandbox environment is used to host a web browser control, where a script is injected from a cloud source to extract content, isolating the client from script management and enabling updates, thus enhancing security and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional parsing solutions are used to extract website content, then content retrieval functionality is provided, but security risks increase due to exposure to malicious code and website updates cause synchronization failures
Solution Approach 1:
The patent introduces a sandbox environment as an intermediary layer between the client system and the website content. This sandbox acts as a mediator that isolates the content extraction process, allowing parsing operations to occur in a controlled, secure environment while preventing direct exposure of the client system to potentially malicious code on websites.
Solution Approach 2:
The system segments the content retrieval process into distinct isolated components: the client system, the sandbox environment, and the website. By dividing the architecture into separate isolated segments, the patent enables secure content extraction while maintaining the ability to update parsing solutions independently within the sandbox without affecting the client system.
2Adaptability or versatility
If custom parsing solutions are developed to handle dynamic website changes, then adaptability improves, but maintenance complexity and hosting costs increase
Solution Approach 1:
The sandbox serves as an intermediary that absorbs the complexity of handling dynamic website changes. Parsing solutions can be updated and tested within the sandbox environment without requiring changes to the client system, thereby maintaining adaptability while reducing overall system complexity and maintenance burden.
Solution Approach 2:
The system creates a copied, isolated version of the website rendering environment within the sandbox. This copy allows parsing solutions to be developed, tested, and updated independently from the production client system, enabling adaptability to website changes without increasing the complexity of the deployed system.
3Reliability
If security measures are strengthened to protect from malicious code, then security improves, but content extraction speed decreases
Solution Approach 1:
The sandbox environment acts as a security intermediary that provides robust protection against malicious code while maintaining efficient content extraction. By confining security-critical operations within the sandbox boundaries, the system achieves strong security without the performance overhead that would result from implementing equivalent security checks in the main client system.
Solution Approach 2:
The sandbox provides beforehand cushioning by pre-establishing security boundaries and isolation mechanisms before content extraction begins. This prior preparation of security infrastructure prevents the need for time-consuming security checks during the actual content extraction process, thereby maintaining high extraction speeds while ensuring security.

AI summary
A client system interacts with a sandbox environment to host a web browser control within the sandbox. A webpage URL, a URL to a script file to be injected into the webpage, a name of the script method to be invoked, and the event to look for to trigger the script method sent to the sandbox environment from the client. The sandbox environment downloads the script file from the cloud using the script URL and loads a rendering engine with the specified webpage URL. The specified script file is subsequently injected into the loaded webpage at the sandbox environment. After the specified event is fired, the sandbox environment triggers the specified script method and stores the results within a results array, accessible to the client system.
