“…The algorithm uses Pedersen's commitment to mask transaction amounts and ensures their correctness through zero-knowledge proof. Alsuqaih et al [34] proposed an effective access control framework to address the issue of personal information data and medical privacy data leakage in the medical field caused by the use of blockchain technology. This framework enables patients to determine the access permissions to their data.…”

With the continuous advancement of information technology, a growing number of works, including articles, paintings, and music, are being digitized. Digital content can be swiftly shared and disseminated via the Internet. However, it is also vulnerable to malicious plagiarism, which can seriously infringe upon the rights of creators and dampen their enthusiasm. To protect creators’ rights and interests, a sophisticated method is necessary to authenticate digital intellectual property rights. Traditional authentication methods rely on centralized, trustworthy organizations that are susceptible to single points of failure. Additionally, these methods are prone to network attacks that can lead to data loss, tampering, or leakage. Moreover, the circulation of copyright information often lacks transparency and traceability in traditional systems, which leads to information asymmetry and prevents creators from controlling the use and protection of their personal information during the authentication process. Blockchain technology, with its decentralized, tamper-proof, and traceable attributes, addresses these issues perfectly. In blockchain technology, each node is a peer, ensuring the symmetry of information. However, the transparent feature of blockchains can lead to the leakage of user privacy data. Therefore, this study designs and implements an Ethereum blockchain-based intellectual property authentication scheme with privacy protection. Firstly, we propose a method that combines elliptic curve cryptography (ECC) encryption with digital signatures to achieve selective encryption of user personal information. Subsequently, an authentication algorithm based on Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) is adopted to complete the authentication of intellectual property ownership while encrypting personal privacy data. Finally, we adopt the InterPlanetary File System (IPFS) to store large files, solving the problem of blockchain storage space limitations.

“…They rely on the financial incentives of honest participation, such as mining rewards, to deter malicious actors. However, a defensive mechanism, Byzantine Fault Tolerance, is still required to guard against malevolent participants and maintain the blockchain's functionality, depending on consensus rules [24]. Information and access to patient records are essential in the healthcare industry.…”

As the size of medical data grows exponentially, safeguarding Electronic Health Records (EHR) via cloud blockchain transactions becomes increasingly critical. This paper presents the Multi-User Groupwise Integrity Ciphertext-Policy Attribute-Based Encryption (GI-CPABE), an efficient framework designed to ensure robust data security. By implementing an Improved Ciphertext-Policy Attribute-Based Encryption (ICP-ABE), the GI-CPABE framework is designed to be compatible with both homogeneous and heterogeneous cloud environments, providing secure access that is role-specific and reliable. A distinctive feature of this framework is its role-based access control mechanism, which efficiently assigns user access rights and roles based on multi-user group attributes, considered as integrity measures. An experimental setup was established on a real-time cloud server, simulating a cloud based EHR system. Test data, mimicking real-world EHRs, was generated and subjected to encryption and decryption processes, evaluating the time efficiency of these operations. The proposed GI-CPABE framework demonstrated optimized storage utilization by calculating the overhead of encrypted data, ensuring data integrity through defined attribute-based policies, and enabling secure, controlled access to medical data. Furthermore, a comparative analysis was conducted to ascertain the effectiveness of the proposed framework against existing models. The implementation of access control mechanisms exhibited robust enforcement of access controls tailored to different user roles such as healthcare providers, patients, and administrators.

“…16 Further, the blockchain infrastructure may assist in resolving issues with authorization for data exchange, which can significantly impede establishing a methodology for exchanging patient data. 17 Finally, the technology can employ time stamping to confirm database changes, which is ideal for dealing with EHR data, especially when several individuals have the authority to alter a record. A considerable proportion of health data is sent across IoT sensor nodes due to the growth of the IoT medical systems, exposing them to safety issues such as eavesdropping and data tampering.…”

Technological advancements in the Internet of Medical Things (IoMT) enable medical services to provide incredibly challenging real‐time functions. The proliferation of health sensors has improved patient monitoring, both for patient care and medical purposes, giving professionals more data for early diagnosis and treatment recommendations. Privacy and security are critical considerations for collecting and transferring data from these heterogeneous sensors across the database and the IoT network. This study leverages blockchain technology to improve Electronic Health Record (EHR) privacy and security. This article proposes a novel decentralized architecture using IoT and Blockchain technology for storing EHR and monitoring real‐time patient data. The proposed patient‐centric framework and architecture offer a straightforward solution that fulfills data integrity and anonymity and meets the data interoperability demands. Self‐contained encryption–decryption and primitive cryptographic techniques enhance the system's security. The proposed study models IoT health sensors such as body temperature, pulse rate, spO2, and Electromyogram (EMG) in a blockchain‐based IoT framework. The proposed system has been evaluated to determine that it can process and store Remote Patient Monitoring (RPM) data with encouraging results. The article provides performance, security, and threat analysis to contribute toward a robust, secure, and smart healthcare system using metrics such as latency, throughput, IoT sensor activity, and resource usage. Experimental results present that the proposed method beats the standard healthcare system regarding service quality and patient data monitoring.
