This paper presents a novel algorithm for high capacity image steganography,

whose aim is to hide a scanned document as a message into a host image. In this approach,

halftoning algorithm is applied to convert the gray-scale scanned...

This article proposes an adaptive steganography algorithm that embeds secret data in a compressed video stream using temporal and spatial features of the video signal and human vidsual system characteristics....
