Multimedia Data Security through Embedded Image

Pankaj M. Bhuyar, Dr. S. W. Mohod

Abstract :

Hiding information in an image in a way that does not affect the original cover image pixels or cause a permanent distortion after extracting that information is known as reversible data hiding technology. Many reversible data hiding schemes have been proposed and successfully applied in military applications. Such schemes are developed to ensure digital images authenticity and integrity without any distortion on the original images. They guarantee that any attempt to change the watermarked image will be detected by the image owner. In this research, an algorithm is proposed to reversibly hide data into encrypted grayscale images in a separable manner. The proposed work exploits only LSB insertion for steganography based on Text, Image, and Audio. Scope exists for adopting frequency domain manipulation which may further improve the security of the signal. We compare the state-of-the-art methods; the proposed approach provides higher embedding capacity and is able to perfectly reconstruct the original image as well as the embedded message. Extensive experimental results are provided to validate the superior performance of our scheme.
