| The multiparty authentication | Our system is governed by a single institution or authority, making it difficult to transfer sensitive information about a person to avoid illegal use of the data. Any authority needs to ask for permission from other legal bodies, even in an emergency. | This particular paper confirms that they have the facility for multiparty authentication. It means any organization can access the data from this system and utilize it as they want [22]. |
| Smart contracts | We use MetaMask for the smart contract wallet in our paper. Without deploying a complete Ethereum node, MetaMask allows users to sign smart contracts and interact with Ethereum blockchains (distributed Ethereum-based programs). On a different node, you do not need to download the Ethereum blockchain in order to utilize the Ethereum network. That is a good thing because the blockchain file is enormous. | The other paper we are comparing did not utilize any smart contracts at all. They are utilizing blockchain, which is a distributed digital network constructed and maintained by computers running particular software. As a result, only the blockchain is used for digital transactions [21]. |
| The access control | Our system has a customized access property. Not everyone is allowed to enter all the icons. There are particular accessible facilities available. | This system cannot control access. It is open to all, as the paper describes [21]. |
| Manageability | Our system can help government agencies manage trusted information by making it simpler for them to access and use vital public-sector data while protecting the information’s security, such as in the healthcare sector. A blockchain is a secure platform that stores an encrypted digital record on numerous computers. It is comprised of documents or blocks of data. These blocks, once assembled into a chain, cannot be changed or deleted by a single actor; instead, they must be verified and managed using technology and common governance rules. | In this particular paper, the authors mentioned their management system in detail, though they are also working with blockchain. But this is kind of vague [22]. |
| Content addressable storage | We built the system based on IPFS features. This is a distribution system that uses a peer-to-peer version-controlled file system with a content-addressable block storage format. We are saving the file on IPFS and sending the addressable content (hash) to the blockchain as a transaction in this framework. We’re saving the file on IPFS and sending the addressable content (hash) to the blockchain as a transaction in this framework. | The authors of this paper provided no indication of the content addressable in their writing [22]. |
