A Privacy-Preserving Image Retrieval Scheme with a Mixture of Plain and EtC Images
Kenta Iida, Hitoshi Kiya
In this paper, we propose a novel content-based image-retrieval scheme that allows us to use a mixture of plain images and compressible encrypted ones called "encryption-then-compr…
A Privacy-Preserving Image Retrieval Scheme Using A Codebook Generated From Independent Plain-Image Dataset
Kenta Iida, Hitoshi Kiya
In this paper, we propose a privacy-preserving image-retrieval scheme using a codebook generated by using a plain-image dataset. Encryption-then-compression (EtC) images, which wer…
A Privacy-Preserving Content-Based Image Retrieval Scheme Allowing Mixed Use Of Encrypted And Plain Images
Kenta Iida, Hitoshi Kiya
In this paper, we propose a novel content based-image retrieval scheme allowing the mixed use of encrypted and plain images for the first time. In the proposed scheme, images are e…
An Image Identification Scheme of Encrypted JPEG Images for Privacy-Preserving Photo Sharing Services
Kenta Iida, Hitoshi Kiya
We propose an image identification scheme for double-compressed encrypted JPEG images that aims to identify encrypted JPEG images that are generated from an original JPEG image. To…
Image Manipulation Specifications on Social Networking Services for Encryption-then-Compression Systems
Tatsuya Chuman, Kenta Iida, Warit Sirichotedumrong +1
Encryption-then-Compression (EtC) systems have been proposed to securely transmit images through an untrusted channel provider. In this study, EtC systems were applied to social me…
Robust Image Identification for Double-Compressed and Resized JPEG Images
Kenta Iida, Hitoshi Kiya
In the case that images are shared via social networking services (SNS) and cloud photo sharing services (CPSS), it is known that the JPEG images uploaded to the services are often…
