Messages can be hidden in any media. Typical media include digital images, sound, and video. Steganalysis is the science of detecting the presence of hidden messages in media.

In this paper we propose a data hiding and extraction algorithm for binary images. Handwritten signature can be easily transmitted through the network using this data hiding method. Here we are implementing bit masking to retrieve alternate bits of the watermark image and stuff that bit to the alternate bit positions in the image file at the source end. The eight bits of a single pixel of the watermark...
