Image compression-encryption algorithms by combining hyper-chaotic system with discrete fractional random transform

•A simultaneous image encryption-compression scheme based on hyper-chaotic system and DFrRT is proposed.•The original image is transformed into a spectrum by DCT and the spectrum is compressed by spectrum cutting.•The algorithm can compress and encrypt multiple images by using Zigzag scanning. Based...
