Abstract

MULTI-BIT LSB STEGANOGRAPHY OF COLOR IMAGE IN DCT DOMAIN

Rajib Biswas and Samir Kumar Bandyopadhyay*

ABSTRACT

We have explored two-dimensional Discrete Cosine Transform (DCT) based steganographic method for hiding the data in a color image (any size) where DCT is used to transform original image (cover image) blocks from spatial domain to frequency domain. Here we propose a novel method for image steganography using key based secret data embedding in frequency domain applying function on it.
