Secured Data Communication using Steganography

Abstract

Secured data communication is highly needed in today’s communication media like internet due to vulnerable of confidential resource in a network which can be easily hack. This reason makes the researchers and other users to start research in order to have good techniques which will improve the security of any confidential resource in a network; one of the techniques is steganography. The main contributions of this paper are to design and implement an application that will embed the secret information in an image by using LSB. This approach is the simplest and straight forward in steganography technique. Due to the redundant pixel in image the embedding secret information in a LSB of cover image will not change the stego image in such a way that can easily detected as stego image. The copyright control is added, this will improve the security of stego image by providing stego key which will help to control in controlling copyright. The communication can be carryout with this secured technique because the small changes in LSB of image pixel will make the cover image and stego image no difference. Even if the image is detected, the copyright control prevents the unauthorized user (third party) from accessing secret information. With this method the communication security is improved.
