Content Policy Enforcement via Pre-crawling Whitelisted Dependencies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content-control systems face difficulties in allowing access to necessary network content for webpage construction while maintaining content policy compliance, as modern websites often rely on external resources not listed in whitelists, leading to broken webpages and complex filtering requirements.
Innovation Solution
A method that involves using a policy enforcement module to determine whether additional network content is associated with a whitelist, allowing inclusion based on confirmation, limiting referrals, and periodically reapplying content policies to ensure compliance, including pre-crawling and compiling specific lists of necessary content for proper webpage construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a whitelist of pre-approved domain names is used to control content, then content policy compliance is improved, but webpage construction reliability deteriorates because modern websites require access to external resources not on the whitelist
Solution Approach 1:
The system performs preliminary actions by pre-crawling whitelisted websites and proactively identifying and adding required external resources to the whitelist before they are needed. This anticipatory approach ensures that when a user accesses a whitelisted site, all its dependencies are already approved, preventing broken webpages while maintaining policy compliance.
Solution Approach 2:
The system implements feedback mechanisms where the content control system monitors webpage construction status and uses this information to dynamically update the whitelist. When external resources are identified as needed for webpage construction, the system feeds back this information to automatically add those resources to the approved list, creating a self-adjusting filter.
2Reliability
If content filtering is applied to all network content, then content policy adherence is improved, but system complexity increases due to the need to track multiple levels of linked contents
Solution Approach 1:
The system segments the content filtering process into distinct stages: initial whitelist checking for the primary website, secondary checking for identified external resources, and conditional approval based on usage patterns. This segmentation breaks down the complex task of monitoring all linked contents into manageable, sequential steps handled by specialized modules.
Solution Approach 2:
The content control system performs self-service by automatically monitoring its own filtering decisions and using this feedback to refine future approvals. The system self-adjusts the whitelist based on observed webpage construction success, eliminating the need for manual configuration and reducing operational complexity.
3Object-affected harmful factors
If external network content is blocked to maintain security, then safety is improved, but user experience deteriorates due to broken webpages and lost functionality
Solution Approach 1:
The system applies local quality by differentiating between different types of network content. Instead of uniformly blocking all external resources, it selectively allows specific external content that is proven necessary for webpage construction. The filtering criteria and approval levels vary based on the specific external resource and its relationship to the original whitelisted site.
Solution Approach 2:
The system performs preliminary verification of external resources before allowing access. By pre-crawling and analyzing external sites to determine their necessity for webpage construction, the system ensures that only essential external content is permitted, maintaining security while preserving user experience for legitimate web browsing.
Data Source
AI summary
A method for supplementing a content policy is provided. The method may include receiving a request to access network content associated with a network content, with the network content including additional network content associated with one or more linked network contents. The method may confirm that the network content is associated with the content policy. The content policy may include a list of pre-approved network contents. Based on the confirmation, the method may selectively provide access to the network content and apply the content policy to the additional network content associated with the one or more linked network contents. A policy enforcement module may determine whether or not the additional network content should be included in the network content, and, based on the determination, selectively allow inclusion of the additional network content within the network content.
