Comparative Analysis on Image Steganography and Watermarking with its Applications

In today’s time, Steganography is going to gain its significance due to the exponential increase and secret communication of probable computer users over the internet. Digital watermarking is a method of data hiding, which give safety of data. The method of embedding data along with the digital audio, images is known as digital watermarking.It can also be explained as the learning of invisible communication that typically deals with the ways of hiding the reality of the communicated message. In general, data embedding is achieved in the multimedia content for patent, communication, image, or text, authentication and also many other purposes. In the image Steganography, secret communication is attained to the message embed into the original RGB and also create a stego-image (created image which is carrying a unseen message). In this survey, we have significantly analyzed a variety of steganographic and watermarking techniques and also have covered steganography and watermarking overview its major types, classification, applications.
