Steganography is one of the important methods that help in the process of hiding infor- mation in various digital objects. It is a science that involves the delivery of confidential information embedded in digital envelope objects suitable for multimedia such as images, audio and video files.This science aims to hide confidential data embedded within digital envelope objects. Steganography technology Through its development of computational power, it has improved and increased the security of existing data steganography techniques.Steganography aims at the inability to reveal hidden data contained within digital envelopes. The purpose of steganography is to maintain secret communication between two parties. This project provides an overview of image steganography, its applications,
