data hiding in encrypted images based on predefined watermark embedding before encryption Process
Signal Processing-image Communication, 2016Co-Authors: Dalel Bouslimi, Michel Cozic, Gouenou Coatrieux, Christian RouxAbstract:In this paper, we propose a novel approach which allows embedding a Message into an encrypted image; a Message that can be accessed whether the image is encrypted or not. To do so, the proposed solution relies on the insertion into the image of a predefined watermark, a "pre-watermark", before the encryption Process. Message insertion (resp. extraction) is then commonly conducted into (resp. from) the encrypted image. It is the impact of this data hiding Process onto the "pre-watermark" that gives us access to the Message into the spatial domain, i.e. after the decryption Process. By doing so, the watermark Processing Process is independent of the knowledge of the encryption key and one only just has to know the watermarking key so as to embed the Message and extract it from the encrypted or decrypted image. Reciprocally, encryption/decryption Processes are completely independent from Message embedding/extraction. We illustrate the feasibility of our approach considering the RC4 stream cipher algorithm and the Least Significant Bit substitution watermarking modulation. Experiments conducted on natural test images and ultrasound medical images demonstrate the general capabilities of our system to securely make available a Message in both spatial and encrypted domains while minimizing image distortion. We further discuss the use of different encryption and watermarking algorithms and we illustrate how our system can be used for ensuring image integrity and authenticity control. HighlightsWe provide an approach of hiding a Message into an encrypted image.We show that the embedded Message can be read whether the image is encrypted or not.We present an implementation of our method based on LSB substitution scheme and RC4.We discuss the performances and the security of the proposed implementation.We precise how our approach can be used for verifying image reliability.

Integrating Application Programs for Bioinformatics Using a Web Browser
2012Co-Authors: Yutaka Ueno, Kiyoshi Asai, Masanori AritaAbstract:We have constructed a general framework for integrating application programs with control through a local Web browser. This method is based on a simple inter-Process Message function from an external Process to application programs. Commands to a target program are prepared in a script file, which is parsed by a Message dispatcher program. When it is used as a helper application to a Web browser, these Messages will be sent from the browser by clicking a hyper-link in a Web document. Our framework also supports pluggable extension-modules for application programs by means of dynamic linking. A prototype system is implemented on our molecular structure-viewer program, MOSBY. It successfully featured a function to load an extension-module required for the docking study of molecular fragments from a Web page. Our simple framework facilitates the concise configuration of Web softwares without complicated knowledge on network computation and security issues. It is also applicable for a wide range of network computations Processing private data using a Web browser.
