Abstract:
With the development of computer and expanding
its use in different areas of life and work, the issue of
information security has become increasingly
important. The art of sending and displaying the
hidden information has received more attention and
faced many challenges. Digital 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 transform that map
integers to integers allow perfect reconstruction of
the original image. In this paper, the steganography
techniques are used to conceal the message in the
digital images. Hence, this system embeds the
message bitstream into the LSB's of the integer
wavelet coefficients of a true-color image. And this
system also applies the RSA algorithm to get more
authentication and protecting content owner’s right.
In this proposed system, the original and stegoimages
are difficult to segregate by the human eyes.
The performance of the proposed system is evaluated
using the peak signal to noise ratio (PSNR).
