Image steganography using integer wavelet transform based on color space approach

Abstract

Steganography is one in all the foremost persuasive approaches to mask the presence of hidden data inside a cover object. Images are one of the suitable cover objects for the Steganography. Current trends support, digital image files as the cover file to hide multiple secret images. Steganography presents the clandestine information can be covered in mediums like image, video and audio. This paper provides a LSB image Steganography technique to hide multiple secret images in a cover image which is in a YCbCr color space format using Integer Wavelet Transform (IWT). There is no optical variation between the stego image and the original cover image. The proposed hardware architecture gives very fast, programmable & cost effective hardware solution in the area of Secure Communication.
