Metadata Extraction for Forensic Analysis of Stolen Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face challenges in quickly identifying the content and potential impact of stolen hardware containing confidential data, as well as determining the owner of such data, due to the difficulty in monitoring physical theft and unauthorized access, which can lead to data exposure and compromise.
Innovation Solution
A system comprising a metadata generation component, security component, and metadata extractor component that generates and monitors metadata associated with a distributed file system, detects degradation events, and extracts relevant data items to generate reports and alerts, facilitating forensic analysis and notification of affected data owners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical theft protection technology is implemented, then security against hardware theft is improved, but the ability to quickly identify stolen data content and notify owners deteriorates
Solution Approach 1:
The system performs preliminary actions by generating and storing metadata products containing data item information before any theft occurs. When a degradation event is detected, this pre-stored metadata enables immediate identification of stolen data content without requiring time-consuming analysis of the stolen hardware, thus resolving the contradiction between security protection and rapid response capability
Solution Approach 2:
The system creates a copy of essential data information in the form of metadata products that are stored separately from the actual data. These metadata copies contain identifiers and characteristics of data items, allowing rapid identification of stolen data through the metadata extractor component without needing to access or analyze the physical stolen hardware, thereby enabling quick response while maintaining security
2Adaptability or versatility
If data is stored without structured organization on hard drives, then storage flexibility is improved, but the ability to identify data owners and content deteriorates
Solution Approach 1:
The system segments data identification information from the actual data storage by creating separate metadata products that contain data item information. This segmentation allows the main storage system to maintain flexibility in storing data without structured organization while the metadata layer provides organized tracking of data owners and content characteristics, resolving the contradiction between storage flexibility and identification capability
Solution Approach 2:
The metadata product acts as an intermediary between the flexible unstructured storage system and the need for data owner identification. The metadata extractor component retrieves information from these intermediary metadata products, enabling owner identification and content characterization without requiring the main storage system to impose rigid structure on the stored data
