The advent and rapid rise of network technology and cloud computing have led to new opportunities for ushering in a new era in telehealth. Thanks to the Internet of Things (IoT) and advances in 5G communication, telehealth is expanding and shows no signs of slowing down. It provides patients including elderly and disabled patients with convenient and easy access to healthcare services across space and time. However, the continuous real-time transmission of health information over networks also exposes private data to the risk of being intercepted by third parties. The privacy of the primary individual patient must be managed under the protection of the patient's anonymous key while storing, transferring, sharing, and adding privacy rights. A question arises: How can we design a secure communication environment for remote access control to personal privacy matters? The patient's electronic medical record is protected by the patient's private key, and our scheme provides a real anonymous design for the patient with absolute autonomy over their privacy. Each update of the cloud medical records is patient-led and performed in a secure tunnel. As a result, this study reveals that the cloud-based iPatient privacy copyright management fully controlled by an individual patient is indeed safe and effective.records is mainly through a secure tunnel to encrypt and decrypt data. The tunnel is constructed by a cryptographic asymmetric public key system or symmetric key agreement. Asymmetric public-key encryption and decryption methods need to maintain huge public and private key pairing creation and storage costs. Accordingly, in recent years, symmetric encryption and decryption by a session key agreement mechanism has managed privacy issues. The main point of the key agreement mechanism is to design a set of zero-knowledge-based communications. The two communication parties cannot transmit information that is derived or reversibly decrypted to obtain the private key, and also cannot reveal personal identities during the medical communication process. This paper proposes, under the above premises, an application to provide medical personal privacy and a copyright access mechanism that is managed in the cloud, where the entire process is conducted in a patient-controlled authorization environment, which can be seen in Figure 1. The paper is laid out as follows. Section 2 introduces the related work. Our protocols are found in Section 3. Security analysis is shown in Section 4. Section 5 shows performance comparisons. Section 6 illustrates the conclusions.Appl.
