In this paper, we propose a proxy system with JPEG bitstream-based file-size preserving encryption to securely store compressed images in cloud environments. The proposed system, which is settled between client's device and the Internet, allows us not only to have exact the same file size as that of original JPEG streams but also to maintain a predetermined image format. In an experiment, the proposed system is verified to be effective in two cloud photo steams: Google Photo and iCloud Photo.arXiv:2201.03469v1 fatcat:h4a7i5ruezfefddgpx4b4bejbe
