This section provides an overview of a blockchain-based data lineage management technique. Independent data providers who agree on the chronological and accountable responsibility of data update operations, such as a Blockchain's sequence of events, can affirm the chronological and accountable responsibility of data update operations. A public blockchain's event sequencing provides tamper-proof time stamps and data update trail consensus. To make the function of data management more user-friendly by the explicit association with annotation content, data should be gathered and replicated using meta data management systems such as [[DataHub]], which can store all forms of data content with appropriate meta data annotation. A reliable/tamper-proof time stamp and traceable accounts provided by a trusted source, such as a [[public blockchain]], can also be included in the meta data annotation. Before being published on a blockchain, the data content and its meta data annotation can be encrypted and version controlled to establish a low-cost, yet secure data lineage trail, reducing the need to store huge amounts of material, which incurs blockchain storage costs. This approach, which includes an upgradeable smart contract system and IPFS as the data storage service platform, lays the groundwork for multi-party data governance that is transparent, low-cost, and programmable. [[David Spivak]]'s work on [[Olog]]/[[Categorical database]] provides a theoretical framework on [[data lineage]]. # Implementation Plan To effectively manage data lineage, we need to implement a system that leverages the strengths of various technologies. Here's a step-by-step implementation plan: 1. **Multi-party Provisioning Service**: Utilize Ethereum Blockchain as the multi-party provisioning service. This will provide accurate time stamps and execute smart contracts. 2. **Data Content Capture**: Use DataHub as the tool for capturing and storing all types of data content. DataHub will also handle the Meta Data annotation. 3. **Encryption and Version Control**: Ensure that the data content and its Meta Data annotation stored by DataHub are encrypted and version controlled using a hash value. 4. **Data Storage**: Store the encrypted and version-controlled data on IPFS. IPFS, or InterPlanetary File System, will serve as the Content Addressable Scheme. 5. **Cryptographic Trail**: By storing the data on Ethereum Blockchain, we can maintain a secure cryptographic trail for data lineage. 6. **Smart Contract System**: Incorporate an upgradeable smart contract system on the Ethereum Blockchain platform. This will enhance the security and efficiency of the data lineage management system. This approach will result in a robust, secure, and efficient management of data lineage, paving the way for a multi-party data governance practice.
