Blockchain Verified Data Storage System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for data storage and distribution are inefficient, requiring individuals or entities to maintain possession of documents over time and for requesting entities to authenticate data, which can be time-consuming and prone to errors.
Innovation Solution
A blockchain system that verifies data before storage, allowing it to be stored in a decentralized and immutable ledger, enabling quick and efficient access by requesting entities without the need for further authentication or document retention by the data owner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored in traditional centralized systems requiring manual verification, then data authenticity can be confirmed, but the process consumes significant time and resources for authentication
Solution Approach 1:
The system performs data verification in advance before storage by having issuing entities authenticate data and obtain digital signatures from verifying entities. This preliminary verification eliminates the need for time-consuming authentication processes when requesting entities need the data, as the authenticity is already established and stored on the blockchain.
Solution Approach 2:
The patent introduces verifying entities that act as intermediaries between issuing entities and requesting entities. These intermediaries provide digital signatures that serve as trusted verification, allowing requesting entities to quickly confirm data authenticity without direct time-consuming verification processes.
2Ease of operation
If individuals retain physical or electronic documents, then data can be presented to requesting entities, but maintaining possession and locating documents over time becomes difficult
Solution Approach 1:
The system enables requesting entities to autonomously retrieve verified data from the blockchain without requiring the individual to physically locate and present documents. The blockchain automatically stores and manages all verified data associated with an individual's identifier, allowing instant self-service retrieval by any authorized requesting entity.
Solution Approach 2:
The patent transitions data storage from physical/electronic documents held by individuals to a decentralized blockchain ledger. This dimensional shift from individual possession to distributed network storage eliminates the burden of maintaining and locating documents while preserving easy access through cryptographic identification.
3Reliability
If electronic data files with metadata are used for authentication, then data is harder to falsify, but verification by requesting entity employees is still required
Solution Approach 1:
The patent introduces blockchain-based verifying entities as intermediaries that provide digital signatures on verified data. This replaces the need for requesting entity employees to perform manual verification, as the blockchain's cryptographic signatures serve as trusted third-party verification that is both reliable and simple to validate automatically.
Solution Approach 2:
The system replaces manual verification processes performed by employees with automated cryptographic verification of blockchain signatures. This substitution eliminates the need for human review while maintaining or enhancing verification reliability, as cryptographic validation is both more accurate and less complex than manual employee verification.

AI summary
A method for verified data storage via blockchain includes: storing a blockchain comprised of a plurality of blocks, each comprised of a block header and a plurality of transaction values, the block header including a timestamp; receiving a transaction notification including an entity identifier and data values; validating the data values based on a validation notification received from a verifying entity; generating a new block header comprised of a current timestamp, a block reference value, and a transaction reference value, the block reference value being generated via hashing of the block header included in a most recent block based on the timestamp, and the transaction reference value being generated via hashing of new transaction values including the data values; generating a new block comprised of the generated new block header and the new transaction values; and transmitting the new block to a node associated with the blockchain.
