Hybrid Fusion Methods in Image Steganography for Secured Data Transmission

Abstract: In the present digital scenario, safe and protected communication is the most important requirement. Steganography is the process of implanting secret information into a multimedia carrier it may be text, image, video or audio etc., by hiding information in the image such a way that no one apart from the intended recipient knows of the occurrence of the message. Image fusion is the operation of mixing relevant information from two or more pictures into a single image. In this paper, the Steganography and the image fusion processes are distinct. By the combination of both processes, the security will be more and it tends to new emerging technology. By applying hybrid fusion where the images are fused twice using an effective fusion method that provides enhanced resultant image. The project Hybrid fusion method in image Steganography finds an application in a very wide range of areas involving image processing.
