With the rapid development of the information technology, the health care technologies already became matured. Such as electronic medical records that can be easily stored. However, how to get medical resources more convenient is currently concerning issue. In spite of many literatures discussed about medical systems, these literatures should face many security challenges. The most important issue is patients' privacy. Therefore, we propose a privacy authentication scheme based on cloud environment. In our scheme, we use mobile device's characteristics, allowing peoples to use medical resources on the cloud environment to find medical advice conveniently. The digital signature is used to ensure the security of the medical information that is certified by the medical department in our proposed scheme.
In recent years, health care technologies already became matured such as electronic medical records that can be easily stored. However, how to get medical resources more convenient is currently concern issue. In spite of many literatures discussed about medical systems, but these literatures should face many security challenges. The most important issue is patients' privacy. Therefore, we propose a secure medical data exchange protocol based on cloud environment. In our scheme, we use mobile device's characteristics, allowing peoples use medical resources on the cloud environment to seek medical advice conveniently.
As the network technologies have rapidly developed in recent years, many Internet of Things (IoT) based services and applications have walked into our daily lives; one of these is the medical information system. In the early days, medical information was recorded and stored in article form. It contains a patient identity background, past medical history, and records of medical payment. With the development of medical technology, medical information is now stored and transmitted electronically. Medical information may be a person's most private information, but due to network operation errors or hacking attacks, there has been a crisis of large‐scale leakage of these personal privacy data in the past. In any cases, how to protect this medical information and ensure the privacy of patients has become a topic worthy of research. Therefore, many kinds of literature discussed how to improve medical information systems. In addition, how to effectively treat patients when accidents happen is also a topic worthy of research. Therefore, combined with IoT technologies and medical devices, it has been opened a whole new future for medical information system. This study focuses on security and privacy issues to design a security scheme for healthcare environments when a person encountered physical emergency. Mobile devices and cloud computing are combined into the proposed platform. The proposed scheme can defend against impersonation attack, man‐in‐middle attack, and replay attack. The modal logic is used to verify the proposed scheme. By using digital signature and SVO logic mechanism, the proposed scheme is proven with nonrepudiation.
With the rapid development of information technology and the continual progress of cloud computing technology, numerous studies have been focused on cloud services; many countries actively promote cloud systems which enhance the convenience of medical treatment and services, an important issue in remote areas. In this paper, we combine the cloud platform and mobile devices to compensate for the lack of medical resources in certain remote areas. We also use cryptographic technology to protect the patient's personal information; additionally, the technology can authorize the medical treatment. The proposed scheme can minimize the misuse of medical resources; patients can employ a simple password and use mobile devices to log in to the public cloud such that the authentication, integrity, privacy and non-repudiation issues can be satisfied. Our scheme can also satisfy other specific security requirements. For example: defend against offline password guessing attacks, replay attacks, impersonation attacks, man-in-middle attacks and insider attacks; this is done without the need to maintain a verification table.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
