The blockchain typically described as a decentralized system in which transactional or ancient statistics are recorded, stored, and maintained throughout a peer-to-peer community of personal computers referred to as nodes. Counterfeit drugs are one consequence of such limitations within existing supply chains, which not only has serious adverse impact on human health but also causes severe economic loss to the healthcare industry. Blockchain technology has gained tremendous attention, with an escalating hobby in a plethora of several applications like safe and relaxed healthcare records management. Similarly, blockchain is reforming the traditional healthcare practices to an extra reliable means, in phrases of powerful prognosis and treatment through safe and cosy facts sharing using SHA Hash Generation Algorithm. Within the future, blockchain will be an era that can probably assist in personalized, authentic, and at ease healthcare by means of merging the entire actual-time scientific information of a patient’s fitness and offering it in an up to date cosy healthcare setup. In this paper, we evaluation each the present and modern day trends inside the subject of healthcare with the aid of imposing blockchain as a model. We also talk the packages of blockchain, at the side of the demanding situations confronted and destiny views. The proposed system executed blockchain implementation in distributed computing surroundings and it gives the automated restoration of invalid chain by using Consensus and Mining Algorithm. In this system, we present a Custom blockchain-based approach leveraging smart contracts and decentralized off-chain storage for efficient product traceability in the healthcare supply chain. The smart contract guarantees data provenance, eliminates the need for intermediaries and provides a secure, immutable history of transactions to all stakeholders. We present the system architecture and detailed algorithms that govern the working principles of our proposed solution. We perform testing and validation, and present cost and security analysis of the system to evaluate its effectiveness to enhance traceability within pharmaceutical supply chains.
A blockchain system can be considered as a virtually incorruptible cryptographic database where critical medical information could be recorded. The system is maintained by a network of computers, that is accessible to anyone running the software. Blockchain operates as a pseudo-anonymous system that has still privacy issue since all transactions are exposed to the public, even though it is tamper-proof in the sense of data-integrity. The access control of heterogeneous patients’ healthcare records across multiple health institutions and devices needed to be carefully designed. Blockchain itself is not designed as the large-scale storage system. In the context healthcare, a decentralized storage solution would greatly complement the weakness of blockchain in the perspective. The blockchain network as a decentralized system is more resilient in that there is no singlepoint attack or failure compare to centralized systems. However, since all the bitcoin transactions are public and everybody has access, there already exist analytics tools that identify the participants in the network based on the transaction history. With popularity analytics, similarity or closeness among topics within large volume of data can be detected. Groups of items or topics can be system generated using closeness relationship formulation. As information flows among different nodes in bitcoin network, Bitcoin transaction is slow due to the fact that information needs to be propagated across the network to synchronize the ledger replicas. The slow dissemination of information exposes a potential security hole for the malicious attacks. Some measures have been implemented to mitigate the number of the blockchain forks in the network by 50%. However, a long-term solution is still needed. Like any other networks, Bitcoin network is no exception when it comes to malicious attacks. One of the notable form of attack against Bitcoin network topology is eclipsing attack by using information propagation knowledge. Bitcoin peer-to-peer network topology can be inferred and utilized by malicious attackers to perform precise attacks such as eclipsing attack. By observing the flooding process of the information flow, a flooding network’s topology can be inferred. A network topology inference method has been proposed along with a proof of concept in real network. The critical players of bitcoin transactions can be identified use various network centrality metrics. Blockchain might replace conventional methods of keeping track of valuable information such as contracts, intellectual-property rights, and corporate accountings.
Personal healthcare records need to be protected with the highest standard. With the increasing number of data breach incidents in the past several years, the awareness of the general public about the personal data privacy will continue to increasing. The necessity for data privacy will grow stronger with an increasing number of services and device collecting our personal data associated with our personal identity. There are techniques that obfuscate the linking of pseudonymous address and the real person such as Coin Join.
II. GOALS AND OBJECTIVES
III. STATEMENT OF SCOPE
Blockchain, the digital ledger technology that can securely maintain continuously growing lists of data records and transactions, has the power to potentially transform health care, according to industry experts. By simplifying and expediting the way the health care industry processes data in such areas as revenue cycle management, health data interoperability and supply chain validation, blockchain has the power to dramatically reduce back-office data input and maintenance costs and improve data accuracy and security. This scope of proposed work in below data-driven areas:
???????IV. METHODOLOGIES OF PROBLEM SOLVING
All these phases are cascaded to each other in which progress is seen as flowing steadily downwards like a waterfall through the phases. The next phase is started only after the defined set of goals are achieved for previous phase and it is signed off, so the name ”Waterfall Model”. In this model phases do not overlap.
V. PROBLEM STATEMENT
In the proposed research work to design and implement a system for health care data and medicine tracking, where user can store all information in single blockchain without any Trusted Third Party (TTP) in fog computing environment. The system also carried out data integrity, confidentiality as well as eliminate the inconsistency for end user. Also we focus our contribution part that is emergency medicine tracking system and give to valid patients.
