# Connecting Database Assets to a Blockchain for Ownership Tracking > This patent describes a way to link digital assets stored in a traditional cloud database to a blockchain-like system, called a distributed trust ledger, using smart contracts to track ownership. - **Patent:** US 12737348 - **Original title:** Database system public trust ledger architecture - **Granted:** 2026 - **Status:** Active - **Times cited:** 0 - **Field:** software, telecommunications, finance, ecommerce, ai_ml ## What it does The system identifies a digital asset, like a unique piece of data, that is already stored in a regular database used by many different groups. This digital asset is owned by one of these groups. The system then creates a 'smart contract' that includes a special digital marker, called a token, for this asset. This smart contract is recorded on a 'distributed trust ledger,' which is like a public, unchangeable record. The token on this ledger is owned by a specific account, and the system makes sure that the original owner in the database is linked to this account on the ledger. Finally, the original database is updated to show that the digital asset is now linked to its token on the distributed ledger. For example, a company managing digital licenses in a cloud database could use this to create verifiable blockchain tokens for each license, proving ownership and transfer history. ## What it does NOT cover - Does not cover creating a digital asset directly on the distributed trust ledger without first identifying it in an on-demand database system. - Does not cover systems where the digital asset is not 'owned by a first one of the plurality of entities' within the database system. - Does not cover a system that does not include a correspondence linking the first entity (database owner) with the first account (ledger owner). - Does not cover a system that does not update the on-demand database system to include a reference linking the digital asset with the token. - Does not cover a distributed ledger that is not designed to be a 'trust ledger' or is not distributed among multiple entities. ## The clever bit The novelty lies in the explicit, two-way synchronization mechanism that connects an existing digital asset in a traditional, multi-entity 'on-demand database system' to a token on a 'distributed trust ledger,' ensuring consistent ownership records across both platforms. ## Real-world examples 1. Systems for tokenizing real estate or other physical assets represented in a database. 2. Digital rights management platforms linking content licenses to blockchain tokens. 3. Supply chain tracking systems verifying product ownership and movement. 4. Platforms for managing digital collectibles or in-game assets with verifiable ownership. 5. Enterprise blockchain solutions integrating legacy data systems. ## Why it matters This technology matters because it bridges the gap between traditional database systems, which are good for managing large amounts of data, and distributed trust ledgers (like blockchains), which are excellent for verifying ownership and ensuring data integrity. By linking assets from existing databases to a ledger, it allows for transparent and immutable proof of ownership for digital items, which can be crucial for digital rights, supply chain tracking, or financial instruments. This approach enhances trust and auditability for digital assets managed across different systems. ## Frequently asked questions ### What does Connecting Database Assets to a Blockchain for Ownership Tracking cover?
