Blockchain‐based IoT architecture to secure healthcare system using identity‐based encryption

Abstract

Nowadays, blockchain and Internet of Things (IoT) are two emerging areas of the Information Technology (IT) sector. These two emerging areas are used in various fields, such as supply chain, logistics and automotive industry. Due to the low processing power and storage space of IoT devices, users' medical information is usually saved in a centralized third party like a clinical repository or a cloud computing environment. Thus, in many cases, users lose control of their medical information, which can result in security disclosure and a single-point impediment. So, an advanced solution is required to improve the data sharing process, while restricting it in terms of security. Blockchain technology with IoT can significantly affect the healthcare industry by improving its efficiency, security and transparency, as well as can provide more business opportunities. The efficient sharing of Electronic Health Record (EHR) can improve the treatment process, diagnosis accuracy, security and privacy. This article proposes a blockchain-based IoT architecture to provide enhanced security of healthcare data by using Identity-Based Encryption (IBE) algorithm. Here, the smart contract defines all the basic operations of the healthcare system, which can be beneficial to all stakeholders. Many experiments are executed to evaluate the efficiency of the proposed scheme. The results show that the proposed scheme is better than the existing renowned schemes.

Using Identity-Based Cryptography as a Foundation for an Effective and Secure Cloud Model for E-Health

“…The critical advantages of distributed computing in medical care are the versatility of the administrations and the works to upscale or decrease the information storage and intrigue Artificial Intelligence (AI) and AI. Reference [ 9 ] proposed a blockchain-based IoT design to give improved security of medical care information by utilizing Identity-Based Encryption (IBE) calculation. The effective sharing of Electronic Health Record (EHR) can further develop the treatment cycle, finding exactness, security, and protection.…”

Cloud security: literature survey

“…Sharma et al [5] are securing the health care files of the hospitals using the identity-based encryption. This health care data is collected in the form of files with the help of block chain-based internet of things (IoT) architecture, during this collection procedures the files are processed through different layers of the architecture.…”

“…Such medical data logs are used for futuristic clinical classification and late audits. It also helps in the reconstruction of past states of medical trials and is represented as a legal procedural report [10], [11]. Thus, the protection, privacy, and security of E-Healthcare-enabled patients' sensitive information from illegal access and making the medical ledgers immutable for futuristics tasks is the prime concerns that need to investigate.…”
