Modified Ebola based image optimization algorithm for secure image transmission

ABSTRACT

Steganographic technique is a way of hiding confidential data that needs to be protected from unauthorized users and also no suspicion should be there that the cover image is carrying the secret information. Therefore, in steganography technique it is critical to have an algorithm that can hide information securely and uses best combination of techniques. In this research the 2 main factors are considered i.e., payload capacity and stego-image quality. In this model different techniques have been hybridised and those are DWT, Huffman Encoding and Ebola optimisation technique. These combinational techniques work on both capacity and image quality. In this database of Covid-19 patients is used as the confidential data and the results that this model has performed better than the existing ones. © 2022 IEEE.
