Abstract:
In the healthcare system, the Internet of Things (IoT) based distributed
systems play a vital role in transferring the medical-related documents and infor mation among the organizations to reduce the replication in medical tests. This
datum is sensitive, and hence security is a must in transforming the sensational
contents. In this paper, an Evolutionary Algorithm, namely the Memetic Algo rithm is used for encrypting the text messages. The encrypted information is then
inserted into the medical images using Discrete Wavelet Transform 1 level and
2 levels. The reverse method of the Memetic Algorithm is implemented when
extracting a hidden message from the encoded letter. To show its precision, equiva lent to five RGB images and five Grayscale images are used to test the proposed
algorithm. The results of the proposed algorithm were analyzed using statistical
methods, and the proposed algorithm showed the importance of data transfer in
healthcare systems in a stable environment. In the future, to embed the privacy-pre serving of medical data, it can be extended with blockchain technology
