New Steganography Technique
Abstract: Recently there has been an increase in the use of the internet, people use it as a part of their daily lives. And to secure their data, steganography and cryptography are used. Here we suggest using a new steganography technique to hide multiple colored images in a single one by using Discrete Wavelet Transform (DWT). The cover image is represented by three color model which is H (Hue), S (Saturation) and I (Intensity), and the secret images are hidden in them. Multiple levels of the cover image are decomposed and the secret images are hidden in them and some of the similar frequencies components are merged. The hidden images are extracted from the stego image. By using this technique the changes done are less noticeable on the stego image compared to the original one with increased security.
