Secured session key-based e-health: Biometric blended with salp swarm protocol in telecare portals

Abstract

Technological emergence-based user-friendly systems have emerged to cope up the security issues in online medical portals. The Government of India is doing loads of works on online health schemes such as “Ayushman Bharat Yojana.” The proposed research technique may be incorporated with existing online portal for secured data transmission. In this proposed methodology, nature-inspired biological algorithm based on salp swarm has been deployed to generate 256-bits session key for secure transmission of medical information. Arruda E.F. et al. have proposed optimal testing policies for diagnosing patients with intermediary probability of disease in the journal of Artificial Intelligence in Medicine (Elsevier: June 2019 (Vol. 97)) with no detailed diagnosis of unknown diseases. Moreover, online expert opinion with secured data communication was not present at their technique. This proposed work resolves the stated issues by encrypting the patients’ fingerprints with lower order session key, and higher order is used for IDEA encrypting the signals. The resultant of both round of encryption is transmitted to a group of known physicians with threshold limits. Several quality testings such as key sensitivity, signal sensitivity, chi-square, session key space, and statistical tests were carried out, and results are compared with existing benchmark techniques.
