Digital Image Sharing by Diverse Image Media

Digital Image Sharing by Diverse Image Media Abstract: Conventional visual secret sharing (VSS) schemes hide secret images in shares that are either printed on transparencies or are encoded and stored in a digital form. The shares can appear as noise-like pixels or as meaningful images; but it will arouse suspicion and increase interception risk during […]


Designing an Efficient Image Encryption-Then-Compression System via Prediction Error Clustering and Random Permutation

Designing an Efficient Image Encryption-Then-Compression System via Prediction Error Clustering and Random Permutation Abstract: In many practical scenarios, image encryption has to be conducted prior to image compression. This has led to the problem of how to design a pair of image encryption and compression algorithms such that compressing the encrypted images can still be […]
