Pixel Masking Based Data Hiding Technique (PMDHT)

In this paper a pixel masking based data hiding technique (PMDHT) has been presented. The main purpose of this paper work is to hide secret message/image/video into source image/video. Here we are embedding secret message/image/video into image/video by choosing standard 3 x 3 mask in a row major order in which each bits of the secret image/video are embedded in the single bit position of the source image/video. A message digest MD5 is generated from the secret image/video and to be inserted in the embedded image/video for additional security purpose. We then perform embedding all this (Secret and MD5) in the source image/video using our proposed technique. Result is analyzed in terms of SNR.
