摘要：Reversible data hiding is a technique used to hide secret message into a cover image by modifying its pixel values slightly. The cover image and embedded message are completely recovered from the marked content. It helps in information hiding with the lossless compressibility of natural images. Histogram modification, difference expansion, Lossless compression, prediction-error expansion and integer transform techniques are used to carry out this research. In this method which is based on histogram is divided into two stages: Histogram generation and Histogram modification. Histogram construction is performed with the pixel pair arrangements and their dissimilar values. Histogram modification is carried out to embed data into the cover image. The process of unhiding recovers the secret message and also the cover image.
