Selective Image Encryption

Recent Advances in Selective Image Encryption and its Indispensability due to COVID-19

This paper discusses how COVID-19 has changed the landscape of multimedia consumption and resulted in an imperative need for better and faster selective encryption techniques and presents a survey of the most recent advances.

A Selective Block Cipher Image Encryption Algorithm based on Otsu-automated Canny Edge Detection, 4-D Hyperchaotic System, Improved Logistic Map and Square Wave SFC

Novel selective image encryption technique based on 4-D hyperchaos, improved 1-D Logistic map, and the square wave space filling curve (SFC) is proposed that outperforms existing schemes.

An Adaptive-Selective Image Encryption with Orthogonal Polynomials, Chaos, LU decomposition and Square-wave Shuffling

A domain-flexible and selective image encryption scheme based on genetic algorithm, non-linear chaotic map, square-wave diffusion and orthogonal polynomials transformation is proposed. Extensive experiments were used to demonstrate efficiency and practicality.

An Adaptive-Selective Image Encryption with Orthogonal Polynomials, Chaos, LU decomposition and Square-wave Shuffling

A new selective image encryption technique based on hyperchaos, random artificial image, orthogonal polynomials transformation and dynamic permutation matrix using Lower Upper (LU) Decomposition is proposed, that outperforms existing approaches.
