A new security solution to JPEG using hyper-chaotic system and modified zigzag scan coding

•We discuss the flaws in a paper accepted in your journal which focused on image compression and encryption scheme.•We give a new scheme and overcome the flaws in that paper.•We achieve a better performance in image compression and encryption.•The compression ratio of our scheme is very close to JPE...
