Abstract (in Japanese) (See Japanese page) 
(in English) Conventional secure image transmision is based on a Compression-then-Encryption system where image compression has to be conducted prior to image encryption. On the other hand, Encryption-then-Compression( ETC )systems where some image encryption can be conducted prior to compression, is expected for privacy protection. A block-based encryption scheme with the assumption of using JPEG compression has been proposed as an image encryption one for ETC systems. However, the image encryption scheme generates the block artifact on images due to the effect of subsampling chroma signals. In this article, we consider the reason why the artifact is generated and then propose a method to remove it. As a result, the method enables us to use any JPEG decoders in the ETC system.
