“…In this regard, a combined encryption and decryption architecture has been proposed, with AES and RSA encryption mechanisms, to encrypt medical records. The result is a more robust decentralised electronic medical record (EMR) repository [ 101 ].…”

Teleworking is an everyday reality in today’s world. Many companies are opting for this way of working remotely, as it improves employers’ satisfaction along with the work–life balance and it does not lead to any significant reduction in performance. In general, the comfortable use of software applications is a priority, and quality aspects such as usability are of vital importance. In this paper, a novel workflow is proposed. It consists of the following components: (1) a tool to manage usability evaluations based on expert reviews, called Usevalia; (2) a set of heuristics to be considered when performing the evaluations; (3) a catalogue of usability requirements to guide the evaluations; (4) a checklist related to the heuristics to verify that the evaluations have been performed correctly by all the auditors; and (5) a set of tasks to know in advance the functionality of the applications to be audited. Personal health records (PHRs) were taken as a case study. This methodology made it possible to involve a total of 31 working groups that evaluated the usability of four PHRs. Concerning the main results, the evaluators agreed that with Usevalia the usability evaluations could go a step further because they are coordinated and can work together remotely. In addition, analyses of usability scores provided insight into current proposals for improving usability of applications.

Today, the confidentiality and security of patient medical records is of great importance. A database where patient records are kept should not fall into the hands of malicious persons. In addition to keeping medical records confidential and secure, their sharing among various entities such as individuals or institutions must be auditable and controllable. This study proposes a method that enables the storage, access, and sharing of medical data without risking security vulnerability. In the proposed method, data are stored on the cloud, whereas data access information and hash values are stored on a blockchain. The three consensus mechanisms (Proof ofWork (PoW), Proof of Stake (PoS), and Proof of Authority (PoA).) for the proposed scheme are implemented and compared with studies in the literature in terms of security analysis.The performance analysis of the proposed method showed that the Proof of Work gives the best result in terms of block size, while the Proof of Stake gives the best results in terms of block creation time and memory usage. The security analysis showed that the proposed method has many security features and is strong against attacks.

“…As discussed in the previous section, e-MR contains patients' confidential information which needs to be shared among multiple bodies. In order to retain data privacy, data integrity, availability, interoperability, reliability, etc., for e-MR sharing system many schemes already have been proposed, e.g., MediChain [5], HDG [8], MediBchain [9], MeDShare [10], MedBlock [11], DPS [12], SEMRES [13], MedChain [14], EHRChain [15], etc. Usually, these works adopt single-fold encryption to retain data privacy and store the plain e-MR metadata or encrypted e-MR over the blockchain.…”

“…Here, to encrypt the e-MR, it also used a public key cryptosystem. Some other works proposed in [6], [7], and [13] also used the blockchain and employed the symmetric cryptosystem to secure the e-MR data. Here, schemes in [7] and [13] used an asymmetric cryptosystem to encrypt the symmetric key.…”

Usually, a medical record (MR) contains the patients' disease-oriented sensitive information. In addition, the MR needs to be shared among different bodies, e.g., diagnostic centres, hospitals, physicians, etc. Hence, retaining the privacy and integrity of MR is crucial. A blockchain based secure MR sharing system can manage these aspects properly. This paper proposes a blockchain based electronic (e-) MR sharing scheme that (i) considers the medical image and the text as the input, (ii) enriches the data privacy through a two-fold encryption mechanism consisting of an asymmetric cryptosystem and the dynamic DNA encoding, (iii) assures data integrity by storing the encrypted e-MR in the distinct block designated for each user in the blockchain, and (iv) eventually, enables authorized entities to regain the e-MR through decryption. Preliminary evaluations, analyses, comparisons with state-of-the-art works, etc., imply the efficacy of the proposed scheme.
