Storage Device NFT Ownership Verification and Data Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing market for used storage devices faces challenges in verifying ownership and authenticity, with sellers concerned about data privacy and buyers facing difficulties in distinguishing genuine from counterfeit products, due to limitations in current data erasure methods and lack of reliable authentication mechanisms.
Innovation Solution
The integration of non-fungible tokens (NFTs) stored on a blockchain to manage ownership and authenticity of storage devices, utilizing unique identifiers, metadata, and smart contracts to verify ownership, ensure data security, and distinguish genuine products, while enabling secure transfer of ownership and encryption key management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software erasure routines are used to erase data before selling storage devices, then data privacy is partially protected, but incomplete erasure leaves readable data blocks that could be recovered
Solution Approach 1:
The patent applies preliminary action by encrypting data before it is written to the storage device. This means that instead of attempting to erase data after storage (which may be incomplete), the data is protected in advance through encryption. The encryption key is then erased, rendering the encrypted data irrecoverable. This approach ensures reliable data protection from the outset rather than attempting retroactive erasure.
Solution Approach 2:
The patent extracts the critical security element (the encryption key) from the storage system and erases it separately. By separating the data (which remains encrypted on the device) from the means to access it (the key), the system achieves complete data protection. The key erasure is a distinct operation that definitively prevents data recovery without requiring complex全盘 erasure procedures.
2Reliability
If manual data overwriting is performed to erase data before sale, then some data privacy protection is achieved, but wear-leveling in SSDs prevents complete overwriting of all data blocks
Solution Approach 1:
The patent changes the fundamental parameter of data protection from physical erasure/overwriting to cryptographic encryption. Instead of attempting to modify or remove data at the physical level (which fails with SSD wear-leveling), the system transforms data into an unreadable encrypted form. This parameter change makes the protection method universally applicable to all storage device types including HDDs, SSDs, and emerging storage technologies without being constrained by their specific physical characteristics.
Solution Approach 2:
The patent replaces mechanical/physical data erasure methods with a cryptographic system. Manual overwriting and hardware erasure routines are substituted with encryption algorithms. This substitution eliminates the limitations of physical erasure methods (such as wear-leveling in SSDs) and provides a more reliable, technology-agnostic solution that works regardless of the underlying storage mechanism.
3Productivity
If online retail markets are used to sell storage devices, then market reach is expanded, but counterfeit devices cannot be distinguished from genuine ones
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that mediates between buyers and sellers in online storage device transactions. This intermediary provides an immutable record of device provenance, ownership history, and authenticity verification. The blockchain acts as a trusted third party that enables market expansion while simultaneously providing the measurement precision needed to verify device authenticity, resolving the contradiction between transaction volume and verification accuracy.
Solution Approach 2:
The patent implements a feedback mechanism through blockchain technology that continuously records and verifies device ownership and authenticity information. Each transaction and ownership change is recorded on the blockchain, providing real-time feedback to buyers about device provenance. This feedback loop enables buyers to verify authenticity before purchase, maintaining measurement precision while allowing market productivity to grow through expanded online transactions.
4Reliability
If encryption keys are erased before sale to protect data, then data security is improved, but there is no reliable way to verify the seller actually performed the erasure
Solution Approach 1:
The patent implements a feedback mechanism where the blockchain network automatically records and verifies key erasure operations. When a seller erases their encryption key, this action is recorded on the blockchain, providing transparent verification to the buyer. The system provides feedback about the erasure status without requiring the seller to provide manual certification, thus maintaining data security while enabling verification through automated, tamper-proof recording.
Solution Approach 2:
The patent introduces a blockchain-based intermediary that mediates the verification of key erasure. Instead of relying on the seller's word or manual verification processes, the blockchain acts as a trusted intermediary that automatically records and verifies the erasure event. This intermediary provides lossless verification information about the erasure action, enabling buyers to confirm data security measures were actually performed without compromising the security of the encrypted data.

AI summary
System, methods, and devices described herein utilize blockchain systems to tie physical storage devices to a digital non-fungible token (NFT). By utilizing this association, the manufacturer can provide software to assure purchasers that their devices are genuine. Furthermore, ownership transfers can be verified and utilized as a means to provide accurate provenance of a storage device, which can increase the value of the device in certain collectible situations. Associating a storage device to an NFT can include pair the drive with a unique identifier provided by the manufacturer, and an address that consists of an encryption key and a secret key that only the owner will know. A user can then encrypt their data and transfer ownership of the storage device to a new owner who will generate a new encryption key. The new owner cannot access data stored on the device, preventing the original owner’s data from being compromised.
