A New Image Steganography Based On First Component Alteration Technique

  title={A New Image Steganography Based On First Component Alteration Technique},
  author={Amanpreet Kaur and Renu Dhir and Geeta Sikka},
—In this paper, A new image steganography scheme is proposed which is a kind of spatial domain technique. In order to hide secret data in cover-image, the first component alteration technique is used. Techniques used so far focuses only on the two or four bits of a pixel in a image (at the most five bits at the edge of an image) which results in less peak to signal noise ratio and high root mean square error. In this technique, 8 bits of blue components of pixels are replaced with secret data… CONTINUE READING
