Image encryption using binary key-images
2009 IEEE International Conference on Systems, Man and Cybernetics, 2009This paper introduces a new concept for image encryption using a binary “key-image”. The key-image is either a bit plane or an edge map generated from another image, which has the same size as the original image to be encrypted. In addition, we introduce two new lossless image encryption algorithms using this key-image technique.

An Encryption Algorithm for ROI Images
2017According to JPEG2000 image encryption algorithm based on confusion of the wavelet coefficients cannot support region-of-interest(ROI) image coding, an encryption method for ROI images is proposed. The proposed method Generates the confusion table using Chaotic sequences, confuses the Wavelet coefficients inside each code blocks, and encrypts the sign ...

Image invisibility assessment for visually encrypted images
2014 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2014A variety of perceptual encryption schemes have been studied to generate visually encrypted images for protecting visual secrecy and privacy while supporting ongoing innovation and growth in the applications of digital imagery. However, typical image quality metrics such as PSNR and SSIM are not suitable to evaluate the invisibility of visually ...

Discrete cosine transform of encrypted images
2008 15th IEEE International Conference on Image Processing, 2008Processing a signal directly in the encrypted domain provides an elegant solution in application scenarios where valuable signals must be protected from a malicious processing device. In a previous paper we considered the implementation of the ID discrete fourier transform (DFT) in the encrypted domain, by using the homomorphic properties of the ...

Efficient Compression of Encrypted Grayscale Images
IEEE Transactions on Image Processing, 2010Lossless compression of encrypted sources can be achieved through Slepian-Wolf coding. For encrypted real-world sources, such as images, the key to improve the compression efficiency is how the source dependency is exploited. Approaches in the literature that make use of Markov properties in the Slepian-Wolf decoder do not work well for grayscale ...
