A 32 bit ASCII … Witryna10 gru 2015 · Image encryption is an efficient tool to provide security to these multimedia data. Many image encryption algorithms have been proposed to protect images by changing their pixel values and/or locations using different technologies [5], [19], [35]. They can be classified into the frequency-domain and spatial-domain image …
Novel image encryption algorithm based on improved logistic map
Witryna29 mar 2024 · Topic of quantum chaos has begun to draw increasing attention in recent years. So, to ensure the security of digital image, an image encryption algorithm based on combining a hyperchaotic system and quantum 3D logistic map is proposed. This algorithm is applied in four stages. Initially, the key generator builds upon the … Witrynalogistic map, for encryption of images. But the future scope in this paper was; the histogram plotted after this strong encryption was not uniformly distributed. Zhang D., Gu Q., Pan Y. and Zhang X. “Discrete Chaotic Encryption and Decryption of Digital Images”, this paper scrambled the row and column for each pixel in the input ... sanctuary series book
A Block-Based Division Reversible Data Hiding Method in Encrypted Images
Witryna13 kwi 2024 · An image encryption model is presented in this paper. The model uses two-dimensional Brownian Motion as a source of confusion and diffusion in image pixels. Shuffling of image pixels is done using Intertwining Logistic Map due to its desirable chaotic properties. The properties of Brownian motion helps to ensure key sensitivity. … Witryna15 sty 2024 · This study proposes a self-adaptive image encryption algorithm based on the quantum logistic map. First, the initial values are substituted into the quantum logistic map based on an iteration process to generate three random sequences.
