Glyph Dataset Security via Segmentation and Key-Value Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data sharing systems via glyphs, such as barcodes or QR-codes, face security challenges as they rely solely on encryption and user authentication, leaving them vulnerable to decryption by skilled individuals without knowledge of the glyph.
Innovation Solution
A method and system for securely sharing datasets via glyphs involves splitting the dataset into multiple subsets, generating a payload from one subset, storing other subsets in a key-value database with a hash value as the storage key, and creating a glyph representing the payload for sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dataset is stored entirely in the glyph, then the data can be accessed directly without external storage, but the glyph size becomes excessively large and security is compromised
Solution Approach 1:
The dataset is divided into multiple data subsets, with only the first subset embedded in the glyph payload. The remaining subsets are stored externally in a database, allowing the glyph to remain small while securing the complete dataset through distributed storage
Solution Approach 2:
A database serves as an intermediary between the glyph and the complete dataset. The database stores external data subsets and uses the payload as a key to retrieve and reconstruct the full dataset, eliminating the need to embed all data in the glyph
2Reliability
If the dataset is split into multiple subsets stored in external databases, then security is improved, but the system complexity increases
Solution Approach 1:
The system merges the glyph scanning functionality with automatic database retrieval and dataset reconstruction. When a payload is scanned, the system automatically uses it to query the database for external subsets and assemble the complete dataset, hiding the complexity from the user
Solution Approach 2:
The payload serves multiple functions: it is embedded in the glyph for sharing, used as a storage key in the database to retrieve external subsets, and acts as an identifier for reconstructing the complete dataset. This multi-functionality reduces the need for separate mechanisms
3Reliability
If encryption is applied to the entire dataset before glyph generation, then data security is enhanced, but the glyph payload size increases and retrieval becomes slower
Solution Approach 1:
The dataset is segmented into subsets before encryption, with only the first subset placed in the glyph. This reduces the amount of data that needs to be encrypted and embedded in the glyph, speeding up the glyph generation and retrieval process while maintaining security through distributed storage of encrypted subsets
Solution Approach 2:
The dataset is pre-split into subsets and pre-stored in the database before glyph generation. This preliminary organization allows for faster retrieval during decryption, as the system only needs to fetch the specific subset identified by the payload rather than retrieving and processing the entire encrypted dataset
