Abstract

Currently Healthcare is a industry with a lot of problems that still need to be solved. Healthcare based medical organizations are currently using a number of mechanisms and tools to exchange patient's medical reports data electronically. The main goals of various health information (HIE) exchange methods include data protection concerns, security risks, poor system transparency visibility, inexpensive costs for health care. Lack of patient control, minimizing medical errors, improving inter-agency information exchanges among health care providers are the main challenges of the standard HIE systems. This encourages the current information exchange models in the health industry to be interrupted and organized by blockchain technology. It can help improve universal access, integrity, security, traceability, and interoperability. Blockchain healthcare applications hold the key to improving the current healthcare condition. Here we will solve the health data exchange problem. A network of data will be created where anyone patient's laboratories, hospitals, doctors, nurses, etc. can easily access records using permission access which will also address privacy issues. This patent disclosure seeks to provide a method for storing and exchanging healthcare information securely through blockchain-based approaches. 24 100 DrugTraceabIity ClinIcITrials EData Module 102 CollictlnModule 134 Palent Data Management Module LO Figure 200> managing medical product data forensuring quality and authenticity of the products upon registering 02 productsproducedbyhealthcareindustrywitharegisteredcompany maintaining a record of clinical trials result performed by researchers in a secured and protected manner 204 upon authenticating the researchers 206 sendingnecessaryinformation tothird party without revealing identity upon creatinghash foreach PHI block combined with patient ID Figure 2

FIELD OF THE INVENTION

The present disclosure relates to a system and method for healthcare information exchange through blockchain-based approaches.

BACKGROUND OF THE INVENTION

Healthcare industry is one of the fast-growing industries in the world. Day by day new innovations take place in this industry to provide better results. Due to these innovations average life expectancies has been increased. According to survey taken by Hyper ledger's,42.9% of healthcare organizations assumes that interoperability of digital records will use for faster blockchain implementation and out of this 2 8 .6 % have responded to use this technology in recent times. Still there is lot of improvement needed for seamless adoption of blockchain in healthcare.

Blockchain based approaches laid the foundation for Bitcoin and after that it has become more popular. Nowadays blockchain is used almost in every area whether it is related to banking sector, agriculture sector, Internet of Things (IoT) and so on. In today's world, health sector is one of the most important area in which block chain is used and it will become the biggest sector by year 2023.

Blockchain technology is based on distributed approach with immutable functionality which means information will not get change till it reaches to the recipient. Due to increase number of patients, it is very much needed that the information like Patient health record, electronics health records, medical insurance claims, data collected from IOT devices and monitoring system are kept safely. To keep these information safe blockchain plays an important role and one of the major advantages is data integrity.

Blockchain is one of the fastest growing and most important technologies in the world. It is a technology that creates immutable and distributable data records that are shared between peers in network database systems and records digital events in such a way that it cannot be altered or recognized until it reaches the recipient. In recent times, many of the industries are using blockchain as a tool to innovate their functionality. Some of the well-known industries are banking sector, real estate, healthcare, internet of things, insurance, and many more. Out of these industries, healthcare is one of the industries that is adopting blockchain very rapidly.

In one of the existing solutions a method for generating and using a portable patient file is disclosed. A method for generating and using a portable patient file may include entering data relating to a patient into a computer and storing the patient data in a medical record for the patient in a database using metadata in an adaptive data environment. The computer is configured to instantiate a file configured for import or export of the patient data, and the file is capable of transferring the patient data from the database to another database with preservation of semantic meanings associated with the patient data.

In one of the existing solutions a system and method for centralized management and monitoring of healthcare services is disclosed. A method of operating a centralized healthcare management system that includes a data translation map database and a central interpolation server computer interconnected to a computer network. The central server receives an initiating request from a requesting terminal for a data record to be retrieved that satisfies a specified condition; then sends a data record request to a source database; then receive a data record from the source database, with the data record being in a source format. The central server references a data translation map database for a desired translation map, with the data translation map enabling the central interpolation server to translate data records from a source format to a destination format. The central interpolation server translates, in accordance with the selected data translation map, the received data record from the source format into a destination format suitable for transmission to the requesting terminal. The central server then transmits the data records in the destination format to the requesting terminal via the network.

In one of the existing solutions a longitudinal electronic record system and method with task-based workflow is disclosed. A system and method for keeping, organizing and managing electronic records, comprising generating a first instance of data objects comprising data elements during a first encounter, the elements comprising a first instance identifier and temporal identifiers; linking a data object to a summarization reference with a pointer; creating an additional instance of data objects also comprising data elements comprising an additional instance identifier and temporal identifiers during a later encounter; and providing continuity for the first instance data objects over time. Continuity may be provided by tracking a relationship between the first instance data object and an additional instance data object and repointing the pointer to point between the summarization reference and the additional instance data object. The additional instance data object may be a revision of the first instance data object, and tracking may occur by back-linking the revision to the first instance data object.

However, there are various systems available for healthcare information exchange as mentioned above, but these systems incapable of protecting from alteration and modification of data by third person.

Further, any person can breach the data easily due to absence of data security techniques which results in spreading of false data.

In the view of the forgoing discussion, it is clearly portrayed that there is a need to have a system and method for healthcare information exchange through blockchain-based approaches.

Referring to Figure 1, a block diagram of a system for healthcare information exchange through blockchain-based approaches is illustrated in accordance with an embodiment of the present disclosure. The system 100 includes a drug traceability module 102 for managing medical product data for ensuring quality and authenticity of the products upon registering products produced by healthcare industry with a registered company.

In an embodiment, a patient data management module 106 is in connection with the clinical trials data collection module 104 for sending necessary information to third party without revealing identity upon creating hash for each PHI block combined with patient ID.

In an embodiment, the blockchain is having two options one is public blockchain and other one is private blockchain. In an embodiment, in case of public blockchain healthcare industry needs to register products with a private company to ensure quality and authenticity of the products whereas in case of private blockchain a central authority having access to drug blockchain.

Blockchain is simply a time stamped series of immutable data or records that is handles by cluster of systems and are not owned by single entity. Each of these data is in the form of blocks and these are kept secured by using cryptographic principles. Immutable data means which cannot be altered or modify during transaction. Some of the important features of blockchain are as follows:

• Blockchain is not owned by single authority that's why it is decent. • Each and every block which takes part are storing the cryptographically data. • It is immutable means no one can tamper the data which is contained in the form of block chain. • Due to its transparency nature the data can be traced very easily whenever needed.

Blockchain is classified into two categories one is public blockchain and the other one is private blockchain. Both are blockchain that means they provide peer to peer network which offers an immutable and decentralized framework and are synchronized using consensus protocol. Consensus protocols are the set of rules that describes about the communication and transmission of data between electronic devices. Consensus is achieved through the agreement done by devices when decision about the data that has to be recorded in blockchain is made. Let us discuss them in details:

Public Blockchain - As the name suggest public which means accessible to all, this means public blockchain is the one which can be read and write by anyone, even anyone can join the public blockchain. In this nobody has control over the network and ensure that data cannot be changed once it is validated on the blockchain. Some of the advantages of public blockchain are as follows: i. Open read and write ii. Ledger is distributed iii. Immutable iv. Secure due to mining

Private Blockchain - Private blockchain is accessible to limited users who are participant of any private network. This provides access though permission and work like centralized systems that provides access to limited users. This blockchain contains one or multiple entities to control the network. Sometimes for controlling there is an identity step through which user come to know about the parts of blockchain network. If anyone don't know who is taking part then it's become very difficult for us to define rules in the blockchain network. Hyperledger, R3Corda and Quorum are the example of private blockchain. Advantages of private blockchain are as given below:

i. Enterprise permissioned ii. Faster transactions iii. Better scalability iv. Compliance support v. Consensus more efficient

Public and private blockchain is depicted in Table 1.

Hashing is the process through which input of any string can be converted into an output of fixed length. Considering the crypto currencies like Bitcoin, it uses the transaction as an input and pass through hashing technique (Bitcoin uses Secure Hashing Technique-256) to generate an output of fixed length. Let us take an example that use SHA-256 (Secure Hashing Technique-256)as hashing technique for generating the output.

Some of the properties of hash function due to which it becomes very useful for blockchain are as follows: • Deterministic: It's all about generating the same hash for the particular input, this is because if the different hash is generated for the same input multiple times then it became very difficult to keep the track of the input. * Pre-Image Resistance: It is very difficult or even infeasible to determine input by observing hash. Suppose H(A) is the hash and for the input A, but just by watch H(A) it is very difficult to determine A. • Snowball Effect: This property shows that if there is small change in input then also there will be huge change in the hash value.

Figure 2 illustrates a method for healthcare information exchange through blockchain-based approaches in accordance with an embodiment of the present disclosure. At step 202, the method 200 includes managing medical product data for ensuring quality and authenticity of the products upon registering products produced by healthcare industry with a registered company.

At step 204, the method 200 includes maintaining a record of clinical trials result performed by researchers in a secured and protected manner upon authenticating the researchers.

At step 206, the method 200 includes sending necessary information to third party without revealing identity upon creating hash for each PHI block combined with patient ID.

Figure 3 illustrates steps for broadcasting or adding data in said blockchain in accordance with an embodiment of the present disclosure. Figure 3 shows different components which take participation in blockchain process which includes different steps that are as follows:

• User Creates Transaction: Transaction is the first step which is generated by user or nodes.

*Transaction as a Block: Now transaction is transformed in the form of block.

• Block is Broadcast: Next, this block is broadcasted though trusted network.

• Network Nodes Approve: Approval of the block by the participating nodes in network.

• Block added to Chain: The new created block is added to the chain of blocks.

*Transaction Entered on Ledger: Entries in the form of transaction is entered in the distributed ledger.

Blockchain has proved to be one of the emerging technologies for many industries, healthcare is one of them. Patients are increasing rapidly and the amount of data is also collected in huge volume, so the healthcare providers have to manage more and more data on a regular basis. Due to this huge volume the complexity is increase and it becomes very difficult for hospitals to manage and store information. Blockchain allows users to perform the following functions:

1) Verifying Public Health Information Integrity 2) Ensure data safety 3) Maintain the integrity of clinical research reports 4) Immutable auditing of medical records 5) Reduction of audit expenses and regulatory compliance

Blockchain provides us more protection than ordinary encryption. This helps us in implementing the new standards in managing medical records, insurance claim, patient health information, etc. It also helps in exclusion of interruption during sharing of data. Many medical organizations hesitate to adopt blockchain due to lack of knowledge in this area. It has been seen quarter of technology experts are still at the stage of learning and exploring the blockchain. Healthcare service providers need more proofs before adopting this technology which includes:

1) Technical proof of concept (PoC) (65. 4 %) - Through this one comes to know about the feasibility and potential of blockchain technology. It is also considered as prototype without any supporting code. This prototype is used by organizations internally who have better understanding about the project. 2) Security proof ( 3 8 .5%) - Security proof is very much needed in blockchain, because when any transaction is done there must be some provision through which the system's security is proved. 3) Privacy proof ( 3 4 .6 %) - Proof techniques are used to protect our privacy. 4) Regulatory approval ( 2 3 .1%) - Blockchain regulations are not vey emerging. So there must be some controlling authority which can regulate the blockchain.

Keeping all the above proofs in mind, it is predicted that blockchain will be widely used in healthcare industries during the coming years.

Some of the following usage issues in health care that has to be processed by blockchain are as follows:

Drug Traceability: One of the biggest problems in healthcare industry is drugs counterfeit. According to HRDO (Health Research Funding Organization), approx 10-30 percent of drugs manufactured in developing countries are fake. According to reports there is loss of more than $200 in the business of US due to this counterfeiting of drugs and side effect of drugs. Blockchain provides a solution for these problems by easily finding fraudulent customers. To deal with these problem blockchain is having two options one is public blockchain and the other one is private blockchain. In case of public blockchain healthcare industry has to register their products with the private company and ensure the quality and authenticity of the products. In case of private blockchain there is central authority which has access to drug blockchain. Blockchain transparency becomes useful when drug moves from retailer to manufacturer and the operational data is recorded on the blockchain. This process makes feasibility during verifying the path of the drug and determines all the chains at any time.

Data Security in Clinical Trials: Clinical trials are the process through which effectiveness of the medicine is tested for specific diseases. This test sometime gets success and sometime it fails. Researchers has to maintain a record during clinical trials because statistics has been done aggressively for generating results, quality reports etc. During this trials researchers tries to make report which cannot be control by everyone. Researchers are solely responsible for specific research. These observations or data can be easily modified or hidden so that whole outcome of the research can be changed. Intruders or hackers are very much interested in recording or modifying the results even if the results do not meet the expectation. Blockchain has done a tremendous job to overcome from these problems. In this user has to prove the authenticity of the documents registered in the system. The proof is given by adding data in the form of transaction and validation is done by all the nodes. As already discussed blockchain contains immutable data that means the result generated from clinical trials can be stored in secured manner. Blockchain can discover modification by comparing a unique data code which is generated by system with the original one. SHA256 calculator is used to generate a unique hash when a modification is done.

Patient Data Management: It is very much needed that PHI (Patient Health Information) must keep secure. Information privacy is controlled by the Health Insurance Portability and Accountability Act (HIPAA). Most common problem related to PHI is that sometimes patient need to share their medical records with other parties especially when they have to buy medicine from the pharmacy store. So these are the problems which have to solve by blockchain especially partial access. Using blockchain patient can send necessary information to the third party without revealing identity. To perform this blockchain creates hash for each PHI block combined with patient ID. Through this patient can decide whom it has to provide partial access or full access. Here even patient can set specific third parties to whom they can give permission for sharing the heath information.

Figure 4 illustrates potential impact of blockchain on healthcare in accordance with an embodiment of the present disclosure. Due to its impact, the healthcare industry can record, store and share the sensitive information related to health issues. However many industries are still in the initial stage to adopt blockchain technology. Let's see some of the facts related to blockchain technology:

• In the first quarter of year 2018, the funding for health startups has reached to its all time high value.

* By the year 2020, it is expected that global health spending will reach to more than $8.734 trillion and this is very huge amount.

In case of healthcare industry there is no financial constraint for research and development of any new innovative technology which will always be a boost for implementation of blockchain. In the above discussions it is stated that health care industry will get benefitted from decentralized medical approach. As per the research done by BIS, the reports have shown that healthcare industry can save upto $100 billion per year by using blockchain technology. The savings can be done by minimizing the cost related to data breaching, operational cost, fraud related cost, fake insurance claims, functional support and personal cost, etc. It is expected that global blockchain in the health care will grow at a CAGR of more than 6 4% from 2019 to 2025 which achieve a target of almost $5.7 billion by 2025.

According to future predictions, it can be said that blockchain in the health care industry will contribute more in the largest market share by year 2025.Now blockchain is adopted by almost all the sectors other than healthcare like banking, agriculture, stock market, crypto currency, etc. The disclosed technology will provides you horizontal innovation to boost the industries so that they can fulfill the current needs.

In an alternate embodiment, blockchain will be applied for improving many areas in healthcare system that are as follows:

• Consent Management: Storing patient consent for exchanging data and privacy preferences during treatment. This will help stakeholders to access the consent of patients and can send anywhere when patient demands. Due to this approach the administrative burden will be reduced and patient care experience will be enhanced.

* Release of Funds wills Become Easier: New methods are developed using blockchain so that remittance and micropayments can be done easy. • Tokenization should be improved for non cash assets including the outcomes generated by blockchain. • Consumption of electricity is very high in blockchain process. So in future there must be change in blockchain infrastructure so that electricity should be minimized. • More and more people must be educated about the benefits and losses of blockchain which can result as implementation of high use cases. • Genomic data should be enhanced by using blockchain technology.
