Transmission Security of Multispectral Images Using Chaotic Maps, Three Dimensional Discrete Wavelet Transform and Secure Hash Algorithm

A rapidly evolving technological world has revolutionized human lives, one such important part of this amazing world is the internet with almost 330 million terabytes of data generated each day. Most of the images generated are multispectral images and these images contains sensitive information which can be related to military, medical, research, agricultural etc. domains. So, when these images are transmitted over the network, there is risk of attacks such as Adversarial attacks which can compromise the accuracy of image analysis, another is spatial attacks where altering the spatial structure of multispectral images can disrupt the relationships between different spectral bands, leading to inaccuracies in feature extraction and analysis, Noise injection, watermarking attacks etc are some of the attacks normally encountered. Hence, to provide overall security to such multispectral images is important. This paper proposes various security approaches which can provide confidentiality, Integrity and authenticity to the images.
