Problem Statement (continued):

Many dApps (Decentralised Applications) will require access to the documents signed by the parties in order to proceed further with business process workflows. One of the viable solutions could be to encrypt the entire document with OpenPGP, store it in IPFS in encrypted format, and allow authorized parties to decrypt it. This solution is far from perfect.

What if you want to hide certain information in the document due to privacy concerns, but the rest of the information should be available? Or if you want multiple parties to have different levels of access to various fields depending on their roles in your business process, how would you do that?

In database terms, this type of granular access is called cell-level security, and some high-end business intelligence solutions, such as Microsoft Analysis Services implement it out of the box; however, these products are expensive and centralized. How would you implement cell-level security in a decentralized network of nodes, such as a blockchain?

Most likely you will move out this document verification process to an off-chain API, compromising the immutability and integrity that blockchain offers while also diminishing the level of trust in your DApp.

Describe your solution to the problem (continued):

Logosphere (https://logosphere.io) - a Layer 2 metadata side-chain backed by Fluree - an open source decentralized semantic graph database (funded in Fund 5) will solve that problem once fully integrated.

Fluree implements data centric security at its core through a feature called Smart Functions which conditionally defines who can access or modify data at the cell level. This way, the access rules are baked inside the data itself residing on an immutable ledger.

Smart Functions can reliably evaluate user identity and user data, because of Fluree's fundamental implementation of cryptographic signatures for all queries and transactions.

In Fluree, an identity is defined by an auth record, which is the central component of data-centric security. Every query and transaction is attributed to a particular auth record which is derived from a user's private/public key.

Since every query to Fluree is cryptographically signed, therefore all the fields that don't have permissions to be visible by a particular identity are ignored and are not included in the query results. This is a simple and intuitive way of making sure that some data at the most granular level stays hidden from unauthorized parties, while being visible to the authorized ones without changing anything in the data itself., which is the central component of data-centric security.

Defining Success

The development of the cell-level security model will go along with the implementation of the Logosphere ecosystem which will span about 9 months with estimated completion in Q2 2022.

3 months in

• Logosphere cell-level security primer (centralized). This will allow for the off-chain data layer running privately to be sharing data with authorized users. Think of a traditional database running on your local network with cell-level security enabled.
• Engage with Cardano DApp projects to identify use cases for data centric cell-level security
• Capture the most common use cases and generalize them into generic model
• Abstract Fluree Smart Functions as easy to use methods as part of a generated TypeScript business object model
• Test the solution in a centralized architecture of "logos nodes" (cardano + fluree) running locally

6 months in

• Logosphere cell-level security primer (decentralized)
• Deploy the cell-level security primer into the infrastructure of beta-testing SPOs
• Repeat the tests from local settings in decentralized scenario where DApp ledgers are replicated across the network of nodes
• Engage the ethical hacking community trying to break the cell level security and get access to not allowed fields in documents in a test ledger.

9 months in

• Widespread adoption of Logosphere by Cardano DApp community
• The issues identified during the testing are fixed
• The cell-level security solution is considered safe
