A Survey on Reversible Image Data Hiding

Abstract

This Reversible image data hiding is one of the popular image processing approach for data security. Image processing is simply the processing of images by using any sort of signal processing, where the input is a picture, a series of pictures, or a video and the output is also either a picture or a collection of properties associated with picture. Data security means protecting data from the persons who are not authorized to access the data. Much work have been done in the field of hiding data in images such as medical images, texture images, aerial images and may more. For this, various techniques have been used such as histogram modification, image encryption, histogram shifting, difference expansion, side match vector quantization, multilevel histogram modification and many more. Normally these techniques worked for gray-scale images. In this study, we describe the main techniques used to solve the problem of reversible image data hiding.
