Content Screening Component Trust Verification via MPEG-7 Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content screening systems lack the ability to verify the trust relationship and categorization standard used by categorization components, leading to ineffective content filtering and protection against inappropriate content in mobile networks.
Innovation Solution
The proposed solution involves extending the MPEG-7 categorization related parts with a CategorizationEntity element to carry information about the categorization component, allowing the content screening component to verify the trustworthiness and categorization standard used by the categorization component, and performing screening operations only when trust is established.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content screening is performed without verifying categorization component trustworthiness, then screening operation can be performed, but the reliability of content screening deteriorates due to inability to verify trust relationship and categorization standard
Solution Approach 1:
The patent applies preliminary action by embedding categorization component information (including identity and categorization standard) into the content metadata before screening. This allows the content screening component to verify trustworthiness and standard compliance in advance, without adding complex verification mechanisms during the screening operation itself.
Solution Approach 2:
The patent uses categorization component information as an intermediary element that carries trust verification data within the content metadata. This intermediary contains identity information and categorization standard information, enabling the screening component to verify trust relationships without direct complex interactions between components.
2Reliability
If categorization component information is embedded in content metadata, then trust verification becomes possible, but the quantity of metadata increases
Solution Approach 1:
The patent makes the metadata structure universal by using standard MPEG-7 classification DS elements that serve multiple purposes. The same metadata structure carries both content classification information and categorization component verification information, eliminating the need for separate verification data structures.
Solution Approach 2:
The patent nests categorization component information within existing content metadata structures. The component identity and standard information are embedded inside the classification DS elements that already contain content category information, creating a nested structure that verifies trust without adding top-level metadata complexity.
3Adaptability or versatility
If multiple categorization components are used, then content coverage improves, but the ability to verify trust relationship deteriorates due to lack of component information
Solution Approach 1:
The patent applies preliminary action by having each categorization component embed its identity information and categorization standard information into the content metadata before screening. This allows the content screening component to verify trust relationships in advance for multiple different categorization components, enabling both broad content coverage and reliable verification.

AI summary
A content screening method, apparatus and system are provided for a content screening component to verify the trust relationship and the categorization standard used by a categorization component. A method includes the following steps: the content screening component receives a categorized content; and when determining that a first categorization component that categorizes the content is trustworthy according to the information of the categorization component carried in the categorized content, the content screening component screens the content by the content category carried in the categorized content. Another method includes the following step: when determining that the categorization component that categorizes the content uses the same categorization standard as the content screening component according to the information of the categorization component carried in the categorized content, the content screening component screens the content by the content category carried in the categorized content.
