Distributed Data Erasure Verification via Feedback and Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributed systems face challenges in securely and verifiably deleting data due to the complexity of managing multiple copies across redundant storage nodes, which is critical for protecting sensitive information from espionage or identity theft.
Innovation Solution
Implementing a method that allows customer entities to securely and permanently erase data by leveraging the inherent secure erase capabilities of storage devices, such as self-encrypting hard disk drives or solid state disk drives, or by encrypting data with cryptographic keys and tracking their disposition, ensuring data is irreversibly inaccessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is replicated across multiple storage nodes for reliability and scalability, then system availability and performance are improved, but the complexity and difficulty of verifying complete data erasure increases
Solution Approach 1:
The patent implements a feedback mechanism where a verification process confirms that data has been successfully erased from all storage nodes. The system receives verification data from storage nodes and processes this feedback to confirm complete erasure, resolving the contradiction by providing automated verification despite the distributed nature of the system
Solution Approach 2:
The patent introduces an intermediary verification process that mediates between the erasure command and the final confirmation. This intermediary layer coordinates the erasure verification across multiple storage nodes, simplifying the overall complexity while maintaining reliability through systematic verification
2Object-affected harmful factors
If secure erasure methods are implemented across distributed storage systems, then data security is improved, but the time and resources required for complete erasure verification increase
Solution Approach 1:
The patent applies preliminary action by establishing verification processes and protocols before the actual erasure operation. Storage nodes are pre-configured with verification capabilities and the verification process is initiated immediately upon erasure command, reducing the overall time required while maintaining security
Solution Approach 2:
The patent segments the verification process into independent tasks that can be executed in parallel across multiple storage nodes. Each node performs its verification independently and reports back, allowing concurrent verification that reduces total verification time while maintaining comprehensive security coverage
