Steganography in high intensity pixel of a thermal image using barcode encoder technique

Abstract

In this research, the high intensity pixels are the region of interest is selected based on the difference in the intensity level of the colors in an image. The image holding the information is hidden in a cover image which is pattern locked in which a random number is allocated for each of the pixel. The pattern is drawn and the nodes that connect each pixel were selected and marked as the area of interest, which has high intensity as said. These numbers extracted and converted to barcode that are saved as normal image. In this proposed research the information that is hidden in the normal image is fused with the thermal image, which comprises of high intensity colors. The image fusion technique which is proposed in this research is much interesting that ensures more security as it do not reveals any clue about the existence of the information to interpreters. This research, analyzes the Barcode Encoder technique in steganography only on colors with high intensity, and identifies those areas where this technique can be applied, so that the human race could be benefited abundantly.
