This paper proposes a novel Image Steganography which can hide an uncompressed secret image stream in a host image stream with almost the same size. Each frame of the secret image will be Non-uniform rectangular partitioned and the partitioned codes obtained can be an encrypted version of the original frame. These codes will be hidden in the Least 4 Significant Bits of each frames of the host image. Experimental results showed that this algorithm can hide a same-size image in the host image without obvious distortion in the host image.
