Reversible data hiding (RDH) is an active area of research in the field information security. In RDH, a secret can be embedded inside cover medium. Unlike other data-hiding schemes, RDH becomes important applications that demand recovery without any deformation, along with hidden secret. this paper, new scheme proposed for performing reversible encrypted images using Fibonacci transform ensembl...

In today’s digital age, ensuring the secure transmission of confidential data through various means communication is crucial. Protecting from malicious attacks during poses a significant challenge. To achieve this, reversible hiding (RDH) and encryption methods are often used in combination to safeguard intruders. However, existing hybrid techniques facing challenges related low embedding capac...

A dual-image-based reversible data hiding (RDH) scheme can conceal secret into a cover image by creating two steganographic images. These stego-images cooperate to extract and restore the image. This paper describes generalization of orientation combination technology for RDH. We first propose full search algorithm find optimal set combinations. Based on algorithm, modification range pixel valu...

While in situ chemical oxidation is often used to remediate tetrachloroethene (PCE) contaminated locations, very little is known about its influence on microbial composition and organohalide respiration (OHR) activity. Here, we investigate the impact of oxidation with permanganate on OHR rates, the abundance of organohalide respiring bacteria (OHRB) and reductive dehalogenase (rdh) genes using ...

Reversible data hiding in encrypted domain (RDH-ED) technology performs content encryption to guarantee the privacy of original media and hide additional for multimedia management or access control. However, three dimensional (3D) model, it is still challenging improve embedding capacity under premise ensuring reversibility. This paper proposes an improvement RDH-ED method 3D models. Firstly, v...

In the field of reversible data hiding in encrypted images (RDH-EI), predict an image effectively and embed a message into with lower distortion are two crucial aspects. However, due to linear regression prediction being sensitive outliers, it is challenge improve accuracy predictions. To address this problem, paper proposes RDH-EI scheme based on adaptive prediction-error label map. stage, thr...

OBJECTIVE To describe the impact of pandemic (H1N1) 2009 influenza (nH1N1) on Indigenous people in the Top End of the Northern Territory at community, hospital and intensive care unit (ICU) levels. DESIGN, SETTING AND PARTICIPANTS We analysed influenza notifications for the Top End from 1 June to 31 August 2009, as well as data on patients admitted through Top End emergency departments with a...

Reversible data hiding (RDH) in dual images is a technique that shares secret messages into two similar shadow images, while the and cover image can be restored only when those shadows are gathered simultaneously. In this paper, novel turtle shell-based RDH scheme based on symmetric property presented order to increase embedding capacity maintain good visual quality under guidance of position-a...
