Inverse computational ghost imaging for image encryption
Optics Express, 2021 Computer-generated random patterns and bucket detection are two key characteristics of computational ghost imaging (GI), which offer it a potential application in optical encryption. Here, we propose an inverse computational GI scheme, in which bucket signals are firstly selected and then random patterns are calculated correspondingly.

Encryption-Then-Compression Systems Using Grayscale-Based Image Encryption for JPEG Images [PDF]
IEEE Transactions on Information Forensics and Security, 2019 A block scrambling-based encryption scheme is presented to enhance the security of Encryption-then-Compression (EtC) systems with JPEG compression, which allow us to securely transmit images through an untrusted channel provider, such as social network service providers. The proposed scheme enables the use of a smaller block size and a larger number of
