Sovereign Data Storage Using Edge Search Keys and Domain Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data handling systems face challenges in efficiently and securely storing data across multiple regulatory domains due to On-Soil regulations, which require different storage, access, and expiration rules for each region, complicating international data management.
Innovation Solution
A global database system with a proxy layer of edge nodes applies regulatory domain rules to authenticate, classify, and encrypt data, assigns meta data based on these rules, and disperses search keys for efficient storage and retrieval, ensuring compliance with regional policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is stored in multiple regulatory domains to enable international access, then data accessibility is improved, but compliance with regional data sovereignty regulations deteriorates
Solution Approach 1:
The system segments data into two distinct components: hot data (frequently accessed) stored locally in edge node caches within specific regulatory domains, and cold data (infrequently accessed) stored centrally in cloud storage. Search keys are also segmented and distributed across edge nodes. This segmentation enables local access to hot data while keeping master copies compliant with regional regulations, resolving the contradiction between accessibility and compliance.
Solution Approach 2:
The patent introduces search keys as intermediary elements that enable data retrieval without direct access to the underlying data files. Edge nodes store search keys locally, allowing fast lookup and retrieval of data locations, while the actual data files remain stored in compliance with regional regulations. This intermediary mechanism decouples access speed from data location, resolving the accessibility-compliance contradiction.
2Speed
If data is replicated across multiple regions for fast access, then retrieval speed is improved, but data sovereignty control deteriorates
Solution Approach 1:
The system segments data access functionality by separating search key storage from data file storage. Search keys are replicated across edge nodes for fast local retrieval, while data files are stored centrally in compliant locations. This segmentation enables fast access through local search key lookup without replicating the actual data, thus improving speed while maintaining sovereignty control.
Solution Approach 2:
The patent adds a new dimension to data access by introducing an indirect access mechanism through search keys. Instead of directly accessing data files from multiple regions, the system uses search keys as an intermediate layer that points to data locations. This dimensional change enables fast access through local cache while maintaining centralized control over data sovereignty.
3Ease of manufacture
If manual processes are used to manage regulatory compliance, then implementation simplicity is improved, but operational efficiency deteriorates
Solution Approach 1:
The system implements self-service automation where edge nodes autonomously determine which data to cache locally based on access patterns, automatically retrieve search keys from cloud storage, and dynamically update local caches without manual intervention. This automation maintains implementation simplicity while dramatically improving operational efficiency by eliminating manual compliance management tasks.
Solution Approach 2:
The system incorporates feedback mechanisms where edge nodes continuously monitor data access patterns and automatically adjust local cache content accordingly. This feedback-driven automation enables the system to self-optimize for both compliance and efficiency, maintaining simplicity while improving productivity through adaptive, rule-based decision-making.
