File Attribute Management via Origin Metadata Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in finding specific files due to limited attribute information, which restricts keyword input and search efficiency, especially when remembering file locations or names is challenging.
Innovation Solution
A method for managing file attribute information by incorporating origin information such as creator, modification, and acquisition details, including IP addresses and physical locations, into the file system's attribute metadata, allowing for enhanced search capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If file searching programs compare keywords with limited attribute information (creation date, modification date, file name, file size, file editor, file type), then the search process is simple and fast, but the search accuracy and completeness deteriorate because users cannot recall exact file names or locations
Solution Approach 1:
The system performs preliminary actions by automatically collecting and storing origin information (creator, modification details, acquisition path, IP addresses, physical locations) when files are created or transferred, before the user needs to search for them. This pre-collected information is stored in attribute metadata, enabling accurate searches without requiring users to remember file details.
Solution Approach 2:
The patent introduces origin information as an intermediary element between the file itself and the user's search query. This intermediary metadata layer (including creator, modification, acquisition path, IP addresses, and physical locations) mediates the search process by providing additional identification points that bridge the gap between limited user memory and comprehensive file identification.
2Loss of information
If only basic attribute information is stored in file metadata, then the file system structure remains simple and easy to manage, but the ability to identify file origin and distribution route is insufficient
Solution Approach 1:
The origin information is segmented into distinct categorical components: creator information, modification information, acquisition path information, IP address information, and physical location information. Each segment is stored as separate metadata fields, allowing the file system to maintain organized, manageable data structures while comprehensively tracking file provenance and distribution.
Solution Approach 2:
The patent adds another dimension to file metadata by incorporating spatial and network dimensions (IP addresses, physical locations, acquisition paths) alongside traditional temporal and descriptive dimensions. This multi-dimensional approach enables comprehensive file tracking without fundamentally restructuring the file system, as metadata naturally accommodates additional attributes.
Data Source
AI summary
A method for managing attribute information of a file and a computing device using the same is provided. The method includes steps of: (a) a first computing device receiving a file with a first origin information inserted into attribute information thereof from a second computing device or from a third computing device connected via the second computing device; and (b) the first computing device instructing a file system to acquire a second origin information from information related to the first computing device, the second computing device, or the third computing device connected via the second computing device, and to insert the second origin information into the attribute information of the file along the first origin information therein.
