Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud storage security is compromised due to the increased attack surface area when outsourcing data storage, risking the integrity and ownership verification of digital assets like images.
Innovation Solution
A system utilizing private blockchains for secure storage and sharing of images, employing non-fungible tokens (NFTs) and cryptographic keys to verify the originality and ownership of digital images, ensuring only authorized users can access and modify the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud storage is used for storing digital data, then data accessibility and storage capacity are improved, but security and attack surface area increase
Solution Approach 1:
The patent segments the storage system into multiple private blockchains, each operating independently with its own security boundaries. This segmentation isolates security risks to specific chains rather than exposing the entire storage infrastructure to attacks, thereby reducing the overall attack surface area while maintaining data accessibility across the distributed network.
Solution Approach 2:
The patent introduces cryptographic intermediaries including public-private key pairs, digital signatures, and hash functions that mediate between users and the stored data. These cryptographic layers act as security intermediaries that verify authenticity and integrity without requiring direct access to the underlying storage infrastructure, reducing the attack surface while preserving reliable data access.
2Ease of operation
If outsourcing cloud storage to hosting company is performed, then storage management and accessibility are improved, but security control and ownership verification deteriorate
Solution Approach 1:
The patent implements preliminary cryptographic actions during data ingestion, where digital signatures and hash values are generated and embedded in the blockchain records before data is stored. This preliminary cryptographic binding establishes verifiable ownership and authenticity credentials that persist throughout the data lifecycle, enabling reliable ownership verification without compromising the ease of storage management provided by the outsourced infrastructure.
3Productivity
If traditional cloud storage is used, then data sharing and accessibility are improved, but data integrity and authenticity verification deteriorate
Solution Approach 1:
The patent implements cryptographic feedback mechanisms where hash values and digital signatures are continuously verified and recorded on the blockchain during data sharing operations. This feedback loop provides real-time authentication and integrity verification that travels with the data across the network, enabling precise authenticity verification that scales with data sharing productivity rather than deteriorating.
