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.

This paper proposes an adaptive steganographic algorithm that embeds secret data in a compressed video stream.

In this paper an estimation

technique for the data hiding capacity in

biometric images is presented. We consider the

QSWT algorithm for data hiding in biometric

images and investigate the effect of message...
