Proceedings of IACT International Conference on Advances in Image Processing   66-71   Aug 2017   [Refereed]
This paper proposes an encryption-then-compression (ETC)-based copyright- and privacy-protected image trading system. It focuses on image copyright protection, consumer's privacy protection, and compression-friendliness with accepting any fingerpr...

Digital Forensics and Watermarking (Lecture Notes in Computer Science, vol.10431)   347-361   Aug 2017   [Refereed]
This paper proposes a method of reversible data hiding (RDH) for high dynamic range (HDR) images. An RDH method once distorts an image to hide data to the image, and the method takes data out and simultaneously recovers the original image without ...
Fujiyoshi, M.; Kiya, H.
Proceedings of APSIPA Annual Summit and Conference   1280-1286   Dec 2015   [Refereed]
This paper proposes a near-lossless compression method for images where the method can conceals data to an image before compression, i.e., a data hiding-then-compression system. The proposed method first preprocesses an image near- losslessly, i.e...
Fujiyoshi M, Kiya H.
Advances in Multimedia Information Processing (Lecture Notes in Computer Science, vol.9315)   2 225-235   Sep 2015   [Refereed]
This paper proposes a near-lossless data hiding (DH) method for images where the proposed method can improve the image compression efficiency. The proposed method firstly quantizes an image in accordance with a user-given maximum allowed error. Th...

SpringerPlus   4(1) 277   Jun 2015   [Refereed]
In conventional image trading systems, images are usually stored unprotected on a server, rendering them vulnerable to untrusted server providers and malicious intruders. This paper proposes a conceptual image trading framework that enables secure...

Digital-Forensics and Watermarking (Chapter "Generalized Histogram Shifting-Based Blind Reversible Data Hiding with Balanced and Guarded Double Side Modification")
Fujiyoshi, Masaaki (Part:Contributor, Chapter "Generalized Histogram Shifting-Based Blind Reversible Data Hiding with Balanced and Guarded Double Side Modification")
Springer Berlin Heidelberg   Jul 2014   
This paper proposes a method of reversible data hiding based on generalized histogram shifting where the proposed method is free from memorizing embedding parameters. A generalized histogram shifting-based reversible data hiding (GHS-RDH) method i...
