EpositBox Blockchain Storage with Sidecar Indexing for Secure PII Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in securely storing and retrieving personal data, particularly Personally Identifiable Information (PII), due to vulnerabilities in data storage systems that make them susceptible to theft and compliance complexities, and existing solutions do not adequately address the need for seamless and secure data retrieval.
Innovation Solution
The EpositBox information handling system uses a network interface, secure memory, and a controller to securely connect with tenant systems, employing hashing and encryption algorithms to protect data, and utilizes a sidecar indexing database to facilitate efficient data retrieval from a blockchain-based storage system, separating liability and ensuring data security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored securely in a blockchain, then data security and integrity are improved, but data retrieval becomes cumbersome and less efficient
Solution Approach 1:
The patent introduces a sidecar indexing database as an intermediary component that maintains parallel copies of data indexes alongside the blockchain storage. This sidecar database enables efficient query processing by allowing the system to first search the indexed data in the sidecar database, and only retrieve from blockchain when necessary, thus resolving the contradiction between secure blockchain storage and efficient data retrieval
Solution Approach 2:
The patent segments the storage system into two distinct components: the blockchain for secure immutable storage and the sidecar indexing database for efficient access. This segmentation allows each component to optimize for its specific function - blockchain for security and sidecar for speed - thereby resolving the efficiency-security tradeoff
2Productivity
If businesses store PII data for operational efficiency and analytics, then business operations are improved, but liability and security risks increase
Solution Approach 1:
The EpositBox system acts as an intermediary that businesses can use to store and manage PII data. By placing data in EpositBox's secure blockchain infrastructure rather than their own systems, businesses maintain operational efficiency through programmatic access while transferring security liability to the specialized secure storage provider
Solution Approach 2:
The patent replaces traditional centralized database storage with a blockchain-based distributed ledger system. This substitution provides immutable, cryptographically-secured storage that eliminates many of the security vulnerabilities inherent in conventional database systems, thereby reducing liability while maintaining data accessibility

AI summary
An information handling system (IHS), method and computer program product secure data such as personally identifiable information (PII) with separated dual encryption of each data payload and obscured labeling, providing an electronic deposit box (EpositBox) to thwart a data breach, which are then stored in a blockchain with retrieval facilitated by a sidecar indexing database. The IHS receives a tenant data structure tenant record(s) having tabular label(s) associated with a data payload. The IHS assigns a block ID, appends a signature, and a tenant identifier to the tenant record. The IHS stores the tenant record in the blockchain, and the block ID and signature are stored in the sidecar.
