A Fundamental Study of Digital Image Watermarking

Abstract

As the use of the internet is at peak nowadays, with which people do communicate and interact with the things easily. Such a kind of use of the internet creates a huge demand for the safety and protection of data. For such safety and security purpose, techniques like water making, cryptography, etc. introduced. With the help of these techniques, we can protect digital data. This survey will represent various aspects of digital watermarking like characteristics of watermarking, types of watermarking technique, merits and demerits, applications, kinds, embedded, and extraction process. Different algorithms will be considered while performing digital watermarking like discrete wavelet transform (DWT), singular value decomposition (SVD), etc. For securing e-governance applications, this survey will be useful for further researches and studies in implementing watermarking techniques.
