“…Broadcast authentication schemes have also been proposed without supporting the confidentiality of the broadcast message in the public key setting [ 23 ]. Recently, Yang et al [ 28 ] proposed a multi-message and multi-receiver signcryption scheme based on blockchain. The scheme enables medical data providers to send messages to multiple data requesters by executing one signcryption operation, which satisfies the multi-message sending requirements of the data providers in the communication environment.…”

Modern healthcare has a sharp focus on data aggregation and processing technologies. Consequently, from a data perspective, a patient may be regarded as a timestamped list of medical conditions and their corresponding corrective interventions. Technologies to securely aggregate and access data for individual patients in the quest for precision medicine have led to the adoption of Digital Twins in healthcare. Digital Twins are used in manufacturing and engineering to produce digital models of physical objects that capture the essence of device operation to enable and drive optimization. Thus, a patient’s Digital Twin can significantly improve health data sharing. However, creating the Digital Twin from multiple data sources, such as the patient’s electronic medical records (EMR) and personal health records (PHR) from wearable devices, presents some risks to the security of the model and the patient. The constituent data for the Digital Twin should be accessible only with permission from relevant entities and thus requires authentication, privacy, and provable provenance. This paper proposes a blockchain-secure patient Digital Twin that relies on smart contracts to automate the updating and communication processes that maintain the Digital Twin. The smart contracts govern the response the Digital Twin provides when queried, based on policies created for each patient. We highlight four research points: access control, interaction, privacy, and security of the Digital Twin and we evaluate the Digital Twin in terms of latency in the network, smart contract execution times, and data storage costs.

The information system of healthcare operates through various frameworks, like wireless body area network, telecare medical information system, and mobile or electronic healthcare. All these systems need to maintain the personal health records (PHRs) for various users (ie, patients, doctors, and nurses). In such systems, we need to process and store the health related sensitive data (ie, PHRs). In this article, we aim to provide a robust security mechanism to secure exchange and storage of healthcare data, especially PHRs. We present a generic architecture of blockchain‐enabled secure communication mechanism for Internet of Things‐driven personal health records (BIPHRS). We then discuss various threats and security attacks of healthcare system along with different available security mechanisms. The conducted security analysis and detailed comparative study of the state of art blockchain enabled security schemes for PHR systems show that the proposed BIPHRS provides a better security and more functionality features as compared to other similar existing approaches.

“…The rise of blockchain technology renders new approaches for data sharing in the medical industry. An anonymous multi‐message and multi‐receiver EHR sharing scheme is proposed by Yang et al, 12 based on blockchain and cloud server as storage to ensure security and immutability. Immutable and non‐tamper blockchain technology features can ensure the integrity of deposited data in the healthcare system.…”

Healthcare Records are becoming more valuable than ever due to the emergence of various new diseases and the current pandemic. These records are scattered throughout multiple healthcare providers in several places. Keeping them in physical form is time-consuming; thus, they need to be kept in electronic form. Electronic Healthcare Records (EHRs) are mostly managed at the individual company level, creating a single point of failure and exposing users to various security risks, including amateur-level attacks and data breaches by hackers. This article proposes a permissioned blockchain-based framework to overcome the above issues for secured storage and sharing of EHRs over the network. For the overall implementation of the framework Hyperledger Fabric (HLF), InterPlanetary Distributed File System (IPFS), and Identity Based Proxy Re-Encryption (IB-PRE) algorithm are used. To create proposed blockchain network, HLF is used. To manage EHRs on the blockchain, IPFS is used where the actual encrypted massive data is stored off-chain, and their corresponding hash values are stored on the blockchain. Further, IB-PRE algorithm is used to share EHRs in a safe manner, where a proxy node retrieves requested data from IPFS, performs re-encryption, and returns the re-encrypted data to the requester thus, ensures user privacy and data integrity. Finally, the Hyperledger Caliper tool is used to run a performance test to check the system efficiency in terms of throughput and latency. Features and performance-based comparisons of the proposed and existing related work are made to demonstrate the effectiveness.
