The increasing availability of medical images generated via different imaging techniques
necessitates the need for their remote analysis and diagnosis, especially when such …

The security of digital images has attracted serious attention lately. In this paper, we present
a novel three-layered image encryption and decryption scheme capable of encrypting and …

Recently, there has been some interest in the development of a homomorphic privacy-
preserving classification method for neuroimages based on the residue number system …

This paper proposes an algorithm that enhances the speed of transmission and secure
images that are transmitted over internet or a network. The proposed cryptosystem uses a …

This study harnesses the useful number properties of the residue number system (RNS) to
minimise energy consumption in a wireless sensor network. In a traditional cluster-based …

In recent times, there has been an increasing attention in designing a homomorphic privacy-
preserving classification method for neuro-images based on the residue number system …

In this paper, we propose a perceptual video encryption algorithm that utilizes rotation matrix
and unit anti-diagonal matrix to visually degrade video data with varying perceptibility …

Purpose: This paper presents a methodology for an image cryptosystem to ameliorate the
problems of many existing digital image cryptosystems. The cryptosystem is based on a gray …

In this paper, the properties of rotation matrices are employed to construct special
orthogonal matrices that are used to encrypt and decrypt video with varying perceptibility …

Secure communication across a digital medium is ensured by data security. The data should
be guided against availability by unrecognised users and communicated to the right …
