Hybrid method based improved steganography

الملخص EN

Since ancient times Steganography was the best way to transfer secret data from one person to another.

The third parties don’t know about the transferred information because it is hidden in another media like image, sound, text or video.

Unlike encryption, confidential information is open to hackers but cannot be used because it is encrypted.in this paper a new data hiding method has been proposed.

In this method the digital image will split into one hindered areas or windows, the standard deviation for each window has computed to choose the smallest fifty values of standard deviation for hiding the data inside this windows.

In each window zigzag bath has used to choose the required pixels to hide the secret bits inside it, the first or the second bit of the binary value of the blue component of the pixels in that path has chosen for embedding.
