Development and Analysis of Stego Image Using Discrete Wavelet Transform

  title={Development and Analysis of Stego Image Using Discrete Wavelet Transform},
  author={Umashankar Dewangan and Monisha Sharma and Swagota Bera},
Steganography is an art of hiding one type of information into other information. Steganography exploits the use of a host data to hide a piece of information in such a way that it is imperceptible to a human observer. Wavelet transforms that map integers to integers allow perfect reconstruction of the original image. Hence, we proposed an algorithm that embeds the message bit stream into the LSB's of the discrete wavelet coefficients of a true-color image. The algorithm also applies a… CONTINUE READING
