Abstract—Steganography is the art that added, imparting mystery information in a proper medium transporter, e.g., picture, sound, and video files. It goes under the suspicion that if the element is noticeable, the intension of the assault is obvious; accordingly the motive is dependable to cover the very presence of the original information. Be that as it may, similar to some other science it can be utilized for sick expectations. In the steganography, information conceals in terms that cannot change the secret information. It’s mainly purpose is transferred data from one location to another location. It means concealed a secret data inside the other data in a manner that a critic cannot find the existence of real subject matters. Concealing the secret data in the images, various types of methods are used in which some are stronger than others to conceal the data. Steganography's definitive targets, which are imperceptibility, vigor (protection from different picture preparing strategies and pressure) and limit of the concealed information are the primary factors that differentiate it from related procedures, for example, watermarking and cryptography. This paper exhibited an overview of the real calculations of steganography conveyed in advanced imaging. The rising strategies, for example, DCT, DWT and versatile steganography are not very inclined to assaults, particularly when the concealed message is less. Steganography necessity is that the cover picture must be precisely chosen. A natural picture ought not to be utilized, it is better for stenographer to make their own particular pictures. There is some method of image steganography are discussed and these methods are different strong and weak points. In this paper, an overview is given of image steganography and its method.
