The healthcare sector has engaged in substantial research in terms of technological advancement to provide patients with efficient and secure services. With the adaption of the internet of things (IoT) in the healthcare domain, remote patients are now able to share their health records with medical experts at distant locations, leading to more efficient and less expensive services. Given that data sharing over the internet entails the patients’ privacy, therefore, it is necessary to ensure that data is transmitted securely so that an adversary cannot tamper with it. Again, as IoT devices are resource-constrained, therefore, it is very important to transmit the data in a lighter format. This paper presents a mechanism for the communication of data or images over the network in a secure and lighter format. The proposed mechanism is implemented on Modified Chebyshev Polynomial and suitable data and image compression techniques with minimum distortion.
