An adaptive steganography technique for videos using Steganoflage

Abstract

Steganography is define as the process of hiding information in a multimedia carrier. Its ultimate objectives are undetectability and robustness of the hidden data. It is recognized as adaptive steganography as the data is embed in to the specific Region of Interest (ROI) of the cover image for the purpose of safety of the inserted data. The assurance of both imperceptibility and robustness requirements are the main objectives of developing an image-hiding technique. The focus is on embedding the data in the skin region of a video frame. Thus focus is on the skin detection algorithm to extract the skin region. This is act as the region of interest for embedding the secret message. The video frames are then converted to YCbCr colour space to perform embedding. The frame having least MSE is selected to embed a secret data. The secret data is then inserted into the Cb component of YCbCr of a frame having least MSE. After embedding secret data Steganoflage video is created by transforming the data into RGB colour space.
