Illegitimate Content Search Prioritizing User Posting History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illegitimate content search methods are inefficient due to the time-consuming process of downloading and comparing large amounts of content from content delivery sites to identify illegitimate content.
Innovation Solution
An illegitimate content search device and method that prioritize content based on a user's posting history, using a profile to determine the likelihood of content being illegitimate by calculating a priority score, focusing on users with records of posting illegitimate content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of possible content pieces are downloaded and compared with legitimate content, then the detection accuracy of illegitimate content is improved, but the search time and processing efficiency deteriorate
Solution Approach 1:
The system performs preliminary actions by acquiring user profiles and calculating priority scores before the actual content comparison. The profile acquisition unit gathers posting history and other user information in advance, and the comparison priority calculation unit pre-ranks possible content pieces based on this profile data. This preliminary sorting ensures that when content comparison does occur, it focuses on the most suspicious pieces first, reducing overall search time while maintaining detection accuracy.
Solution Approach 2:
The system applies local quality by differentiating treatment based on individual characteristics. Instead of uniformly processing all possible content pieces equally, the system assigns different priority levels to different content pieces based on the user's profile and the specific content's characteristics. This allows the system to focus intensive comparison resources on high-probability illegitimate content while applying lighter processing to lower-priority items, optimizing the balance between accuracy and speed.
2Reliability
If all possible content is downloaded and compared, then the completeness of illegitimate content detection is improved, but the processing efficiency and time consumption increase significantly
Solution Approach 1:
The system performs preliminary sorting and ranking of possible content pieces before actual comparison based on user profiles and priority calculations. By pre-organizing the comparison queue according to priority scores derived from profile data, the system ensures comprehensive coverage of high-risk content while efficiently skipping low-priority items, thus maintaining detection completeness without proportionally increasing processing time.
Solution Approach 2:
The system applies partial action by selectively comparing only the necessary portion of possible content pieces rather than uniformly processing all of them. Based on the calculated priority scores and user profiles, the system determines an optimal sampling strategy that compares enough content to achieve reliable detection completeness while avoiding unnecessary processing of low-probability candidates, thereby improving overall processing efficiency.

AI summary
An objective of the present invention is to achieve greater efficiency in searches for illegal (illegitimate) content. The illegitimate content relates to content posted by an unauthorized user without a legitimate ownership of the content. An illegitimate content search device according to the present invention comprises: a content profile acquisition part for acquiring a profile including a posting history of illegitimate content posted by a user having posted candidate content being potentially illegitimate content; and a matching priority calculation part for calculating, on the basis of the profile, the priority of the candidate content with regard to determining whether a plurality of pieces of content is illegitimate content, and elevating the priority of the illegitimate content with a history of having posted the illegitimate content higher than if content without the history.
