Abstract

Internet of Medical Things (IoMT) is a group of medical devices that connect the healthcare information technology to minimize the redundant hospital visit and healthcare system troubles. IoMT connect the patients to the doctor and transmit the medical data over the network. The spread of corona virus has put the people at high risk. Due to increasing number of cases and its stress on health professionals, IoMT technology is used in many healthcare centers. But, the security level and data classification accuracy was not improved by existing methods during the data communication. In order to solve these issues, Cayley-Purser Cryptographic Secured Communication based Jackknife Correlative Data Classification (CPCSC-JCDC) method is designed. The key objective of CPCSC-JCDC method is to collect the patient information through IoMT devices and send to the doctor in more secured manner. Initially in CPCSC-JCDC method, the patient data is collected. After the data collection process, the data gets encrypted with help of public key of the patient by using cayley-purser cryptosystem. After the encryption process, the data is sent to the doctor. The doctor receives and decrypts the patient data by using their private key. After decryption process, the doctor analyses the patient data and classifies the data as emergency case or normal case by using jackknife correlation function. This helps to minimize the patient readmission rate and increase the patient satisfaction level. Experimental evaluation is carried out by Novel Corona Virus 2019 dataset using different metrics like data classification accuracy, data classification time and security level. The evaluation result shows that CPCSC-JCDC method improves the security level as well as accuracy and minimizes the time consumption during data communication than existing works.

Conflict of interest statement

Declarations. Competing interests: The authors declare no competing interests. Ethic approval: (a) Given that our study primarily utilized freely available novel-corona-virus-2019-dataset from sources such as the https://www.kaggle.com/datasets/sudalairajkumar/novel-corona-virus-2019-dataset , direct interaction with individual players to obtain verbal consent was not applicable. The dataset consisted of publicly accessible data where participants’ identities were not individually identifiable, thereby eliminating the need for individual informed consent. (b) In line with ethical guidelines and regulations, our study protocol was reviewed and approved by the Imam Khomeini Naval Science University. Given the nature of the dataset being publicly available and devoid of personally identifiable information, the requirement for individual informed consent was waived by the ethics committee. (c) Our research design and consent procedures were reviewed and approved by the Ethics Committee of Imam Khomeini Naval Science University, ensuring compliance with relevant guidelines and regulations. The committee recognized that the use of publicly available video data did not necessitate individual informed consent from participants, thereby validating our approach.
