Image Steganography with Triple DES and Random Pixel Selection: A Secured Data Hiding Approach

Abstract

In recants years, The fast development of digital communication and information technology has made it crucial to ensure secure data transfer between the sender and the recipient. Steganography Thus, introduces a strong way to communicate secret data and conceal information in the right multimedia carrier, like that image, both audio and video files. In this work, explores an innovative approach to image steganography, integrating the Triple DES encryption algorithm a Random Selection of Pixels technique as to enhance the safety and imperceptibility that of hidden data. The encryption process involves the Triple DES algorithm for robust protection of confidential information, while a strategic Random Pixel Selection method ensures discreet embedding within the image. 3DES uses 168-bit key length which is much more secure than a 56-bit key of DES that making it more resistant to many attacks. An additional layer of security is provided in 3DES alternative use of DES. Even if one of the keys is compromised, the intruder would need to break two more layers of encryption. Then, Random pixel selection can enhance the security of the steganographic technique. By choosing pixels randomly and employing an 8-directional pixel selection approach, the pattern of changes in the image becomes less predictable. This randomness can make it is more difficult for opponents to detect the existence of secret information The distinctive contribution of this work lies in its ability to significantly improve imperceptibility compared to existing methods, offering a robust and visually seamless data hiding approach within the realm of image steganography.
