Objective: This paper is aimed to study the data hiding technique using RIDH over encrypted domain. Methods/Statistical analysis: In recent surveys show the different data hiding mechanisms in non encrypted domains. But still there is gap in applying the data hiding techniques in encrypted domain. To fulfil this gap, we propose a novel reversible image data hiding (RIDH) scheme over encrypted domain. The data embedding is achieved through a public key modulation mechanism, in which access to the secret encryption key is not needed. At the decoder side, a powerful two-class SVM classifier is designed to distinguish encrypted and non-encrypted image patches, allowing us to jointly decode the embedded message and the original image signal. Findings: To evaluate the efficiency of our proposed work, we compared with the state-of-the-arts, the proposed approach provides higher embedding capacity, and is able to perfectly reconstruct the original image as well as the embedded message. Extensive experimental results are provided to validate the superior performance of our scheme. Applications/Improvements: we collect the test dataset which includes 100 images with size of 512 x 512. All these images are downloaded from the following link https://dl.dropboxusercontent.com/u/103270026/TestImage.zip.
