Digital Watermark Techniques and Its Embedded and Extraction Process

The development of the digital communication system is increasing rapidly and all the manual data management process is massively converted to the digital processing system to make faster processing and reduce the valuable time of human users and increase productivity. Now the input and output system of the device is converted to a higher-level interface medium so that the device can communicate with the user and environment through audiovisual components and communicate like a human. Also in the present scenario devices are implemented by human society to deal with very secure and sensitive information like banking, the military, the research environment, the medical sector, etc. Hence there is a chance of misutilization of information through the device. Many Security using mathematical techniques like cryptography, digital signature, etc. are used to make secure information from the unauthentic person, but to protect the copywriting of the digital information watermark technology is used. Through the watermark, we can add the identification of the owner hence the other person can not claim or tamper with the information for its misutilization. In this proposed work we reviewed different techniques to create a watermark with the algorithm associated with it which helps the researcher extend the watermark technique in a better way.
