Example two: a beauty data storage system based on a block chain comprises a public block, a private block and a confidential block chain, wherein the public block is used for storing diagnosis and treatment operation and diagnosis and treatment information; the private block is configured for storing patient personal medical records; the private block chain is configured to verify the identity of the public block and the private block; the public block and the private block are both connected with the secret block chain. Specifically, the public block stores the diagnosis and treatment operations and the diagnosis and treatment information, and the diagnosis and treatment information includes information related to a doctor, such as information of the doctor or a hospital, and practice information. In addition, a public account book is further arranged in the public block, and the public account book is used for recording the operation. The public chain and the private chain are provided with nodes, and the nodes of the private chain and the public chain are different. When the confidential block chain is identified, the confidential block chain needs to traverse each node of the public chain and the private block chain. In addition, the confidential block chain is only used for identifying the nodes, and does not perform networking or sharing operation outside, so that the safety performance of the whole system is effectively ensured.
Also provided in the present invention is a method comprising one or more of: the method includes receiving medical data of a user, creating metadata of the medical data including a unique identifier of the user and medical data describing a searchable description of the medical data including one or more attributes therein, but not disclosing the medical data, encrypting the medical data to generate encrypted medical data, generating a data block having stored therein the created medical data and the metadata of the encrypted medical data, and storing the generated data block in a ledger in a distributed database so as to hash the generated data block to a previous data block on the ledger. With blockchains, the data in this embodiment provides trusted and responsible storage via a transaction ledger that can only be modified based on the consensus of the nodes in the blockchain. At the same time, traditional databases cannot be used to implement example embodiments because traditional databases do not provide the same level of trust and responsibility for data. That is, conventional databases are constrained by a single entity that controls access to information, whereas the blockchain system herein provides distributed access that must only be provided if agreement is reached between nodes. In addition, the blockchain distributed ledger maintains an agreed audit trial that provides a layer of accountability that is not possible in a single-entity control database. Further, metadata information is created and made available through a blockchain, thereby enabling a search of medical data to be performed without revealing underlying confidential information. Additionally, the overall system includes one or more network interfaces configured to receive medical data of the user, and a processor configured to perform one or more of creating metadata of the medical data, the metadata including a unique identifier of the user and searchable. Describing a description of medical data that describes one or more attributes included in the medical data but does not disclose the medical data, encrypting the medical data to generate encrypted medical data, generating a data block in which the created medical data metadata is stored, and the encrypted medical data, and storing the generated data block in the distributed ledger so as to hash the generated data block to a previous data block on the distributed ledger.
The diagnosis and treatment records comprise personal identification, vital organs, family medical history, medical conditions, medicines, allergens, immunity, diet restriction and genome data, wherein a digital encryption subchain is arranged in a private block and is configured to set a specific digital address for the diagnosis and treatment records, and the digital address encrypts all data in the private block. In particular, the medical records are performed using block link points within a network of nodes implementing a health-related block chain as described herein. And the data in the private block is encrypted by using the digital address, so that the personal information on the private block can be effectively ensured. Additionally, receiving medical data of the user may be included. For example, the medical data may include health-related information, such as medical records, drug information, vital signs, disease information, allergies, injuries, treatment information, physician records, and the like. The medical information may be information that is supervised by a chain of secret blocks, which may prevent unauthorized disclosure of such information.
Also provided in the public block is a search means arranged such that the patient requests medical data of a particular user and receives access to the medical data only when the chain of medical data blocks receives consent from the user. In particular, the search means is capable of searching through one or more attributes contained in the medical data without disclosing the medical data. For example, the searchable description may provide an overview of the underlying medical information without revealing the medical information. In some embodiments, the searchable description of the medical data may include a textual description of the type of medical data. Such as "health records", "vital signs", "treatment recommendations", "doctor notes", "medication information", etc. A list of unprotected information such as date/time, doctor's name, nurse's name, hospital information, contact information, etc. may also be provided.
The data storage system further comprises a chain code verifier, a public key and a private key, the public key and the private key being stored at the chain code verifier, and further the chain code verifier is configured for detecting whether there is a right to access. Specifically, the chain code verifier is provided with a block identification node, and the block identification node, the private block and the public block are mutually identified and used for verifying whether the public key and the private key are authorized. In particular, when a user device submits medical data to a chain of medical data blockchains for storage therein, the individual nodes of the chain of medical data blockchains must fulfill a consensus or intelligent contract regarding the storage of the medical data based on one or more predetermined policies. In addition, the medical data may be stored as one or more blocks in a distributed ledger that is replicated across nodes in a chain of medical data blocks. The patient device may access a peer node of the blockchain of medical data and perform a search for the medical data stored therein. However, in addition to searching the actual data, the search results may include only metadata of the medical data. The metadata may not disclose the underlying medical data, but may be a general description, date/time, and name of the doctor, etc. By searching, the patient device may request medical data for a particular user and receive access to the medical data only when the blockchain of medical data receives consent from the user device. For example, consent may be received via the message and the chain of medical data blocks may be triggered to unlock keys used to encrypt the medical data. In addition, the key may be encrypted using the patient's public key and provided to the patient for use in decrypting the user's medical data. The whole system also has its own public key, private key and unique user ID for each user (data owner or data user). The shared key between users can be used to disclose the public key to other parties in the blockchain network through the key management service. Examples of data owners and patients are patients and healthcare providers, respectively. The system can be stored on a blockchain ledger for each user for record keeping and provenance.
The data storage system also includes a transaction ledger that provides trusted and responsible storage, the transaction ledger being modifiable based on consensus of nodes in a blockchain, the transaction ledgers being disposed in the public and private blocks, respectively. In particular, a blockchain is a distributed system that includes a plurality of nodes that communicate with each other. The blockchain runs a program called chain code, saves state and ledger data and performs transactions. Some transactions are operations invoked on chain codes. In general, blockchain transactions must typically be approved by some blockchain members, and only approved transactions can be submitted to the blockchain and affect the state of the blockchain. Other non-approved transactions will be ignored. There may be one or more special chain codes, collectively referred to as system chain codes, for managing functions and parameters. A node is a communication entity of the blockchain system. The nodes may perform logical functions in the sense that multiple nodes of different types may run on the same physical server. The nodes are grouped in trust domains and associated with logical entities that control them in various ways. The nodes may comprise different types. Another type of node is a peer node that can receive transactions submitted by customers, submit the transactions, and maintain a copy of the state and blockchain transaction ledger. Although not required, such as: a subscription service node or subscriber is a node that runs communication services for all nodes and implements delivery guarantees, e.g. broadcasts to each peer node in the system when submitting transactions and modifying the world state of the blockchain, which is another name for initial blockchain transactions, typically containing control and setting information.
The public block is also provided with a distributed ledger, the distributed ledger maintains an agreed audit test, the audit test provides a layer of accountability system which cannot be realized in a single entity control database, and metadata information is created through a block chain and the distributed ledger is made available, so that search of medical data can be executed without revealing basic confidential information. In particular, a distributed ledger is a ledger that is replicated, in whole or in part, to multiple computing systems. One type of distributed ledger is an encrypted distributed ledger that can have at least some of the following properties: irreversibility, which cannot be undone once a transaction is recorded; accessibility, any party can access all or part of it; chronological and time-stamped, each party knows when the transaction is added to the ledger; based on consensus, transactions are only added when the transactions are generally agreed upon by parties on the network; verifiability, all transactions can be password verified. Although the description and drawings herein are described in terms of blockchains, the present application is equally applicable to any type of cryptographically distributed ledger. The application at the user end checks/verifies the peer signature and compares the proposed responses to determine if the proposed responses are the same. If the chain code only queries the ledger, the application will check the query response and will not typically submit the transaction to the subscribing node service. If the client application intends to submit the transaction to the subscribing node service to update the ledger, the application determines if the specified endorsement policy has been met prior to submission-i.e., all of the peer nodes required for the transaction have endorsed the transaction. Here, the customer may include only one of the parties to the transaction. In this case, each client may have its own approval node, and each approval node needs to approve the transaction. The architecture is such that the approval policy will be enforced by the peer and retained during the commit validation phase even if the application chooses not to check the response or otherwise forward the non-approved transaction. After a successful check. In addition, the client assembles the endorsement into a transaction and broadcasts a transaction proposal and response in a transaction message to the node ordering the drug. The transaction contains a read/write set, a peer signature and a channel ID. Corresponding sorting nodes are also generated while queued, which do not need to examine the entire contents of the transactions in order to perform their operations, but rather the sorting nodes may simply receive transactions from all channels in the network, sort them in chronological order by channel, and create each transaction block. And (4) a channel. Blocks of the transaction are passed from the sequencing node to all peer nodes on the channel. Transactions within the block are validated to ensure that any events are satisfied and that the ledger state of the read set variables has not changed since the transaction generated the read set. Transactions in the block are marked as valid or invalid. In addition, each peer node appends a block to the chain of channels and, for each valid transaction, submits a write set to the current state database. An event is issued to notify the client application that the transaction call has been immutably attached to the chain and to notify the transaction as to whether it is validated or invalid.
Example three: on the basis of the second embodiment, the data storage system of the present invention manages consent through the blockchain system and method using encryption and decryption keys. Each user of the system, namely: the data owner or data user has their own public key, private key and unique user ID. The public key may be disclosed to other parties in the blockchain network through a key management service. Examples of data owners and users are patients and healthcare providers, respectively. The system and method comprise the following steps. Each step may be stored on the blockchain ledger for record keeping and provenance.
The data owner uploads the medical data to the blockchain. For example, the medical data may include treatment information, medical records, medication information, doctor notes, patient notes, other medical information, and the like.
In this step, the data owner or the block chain node representing the data owner generates the identification code of the data, the symmetric key of the data and the metadata of the medical data. The metadata may not expose the medical data, but may provide a searchable description of the medical data. To generate a data block, a data owner may store metadata information within the block. The metadata information may include metadata that the data owner may provide to or generate by the data owner. Further, the data owner encrypts the medical data using the symmetric key to generate encrypted medical data. The data owner may also encrypt the symmetric key with a public key of the data owner to generate an encryption key. Here, the encrypted medical data and the encrypted key may be stored in a data block. Also stored in the data block is a hash of the data of the previous block, encrypted using the public key of the data owner or another key known to other nodes. The hash of the data of the previous chunk may include the medical data stored in the previous chunk, and by including the hash of the data from the previous chunk in the data chunk, a hash link may be created between the two chunks. In addition, the data patient may search for and request access to the medical data stored in the first step.
For example, the blockchain link points may output a search interface, e.g., a user interface, a search bar, etc., that enables a data patient to search the metadata of the medical records stored on the medical data blockchain without revealing underlying medical data. When a patient finds data of interest to them, the data patient can use the data owner to retrieve the data owner's public key. Further, the patient may generate and store data chunks on the medical data blockchain, requesting the medical data of the data owner. For example, a data patient may generate a data block that includes data of the data patient that is signed by the data patient and that is of interest to them. Here, the elements of the data block may be encrypted using the public key of the data owner. The method may include encrypting the medical data to generate encrypted medical data. For example, the encryption of the medical data may include encrypting the medical data based on a symmetric key. The symmetric key may be generated by a block chain node and may be a private key that is not available to other nodes/patients. The method may include generating a data block in which the created medical data and metadata of the encrypted medical data are stored. It is also possible to encrypt the symmetric key based on the public key and store the encrypted symmetric key in the generated data block. Here, the public key is known to the block chain node of the system. Thus, when the user agrees to disclose his health/medical information. They can authorize the block chain nodes to decrypt the symmetric key and share it with the requesting patient. In some cases, the chunk chain node may encrypt the decrypted symmetric key using the public key of the data consumer to keep the symmetric key protected.
