Abstract :
Steganography is an art of activity the data within the cover like the simplest way that, it´s like straightforward cover, though its hidden information. In this paper, secret image is activity into two completely different domains like as IWT (Integer Wavelet Transform) and DWT (Discrete Wavelet Transform). The cover image and secret image coefficient values square measure embedded by 512*512 exploitation fusion process techniques. We tend to applied numerous combinations of DWT and IWT on each images and obtained a decent quality stego images. The each domain offers safer with secret key and sure robustness of our algorithm. This dual wavelet transform utilized in Color Image Steganography Method (DWTSM) in Blue Channel (B-Channel) provides high capability and security. This proposed algorithm is tested with image quality parameters and compared to other algorithms. The experimental Results show that dual based approach achieved high capability and high security of our system in B-Channel and conjointly improves the performance of steganography system. The proposed algorithm achieved high PSNR quantitative relation 45 to 55 and other parameter values achieved the best solution and this methodology compared to different combination of transform.
