ABSTRACT- In recent years, digital media are widely popular, their security related issues are becoming greater importance. Watermarking is the process of hiding digital data in a carrier signal. Embedding a digital signal such as audio, video or image with the information which cannot be removed easily is called digital watermarking. Digital watermarking mainly used to verify the authenticity, integrity of the carrier signal or to show the identity of its owners. In this paper, we present a survey on various digital watermarking techniques. This paper mainly concentrates a detailed survey of all watermarking techniques on image watermarking types in today’s world.
Index Terms – Digital watermarking, spatial domain, Least Significant Bit (LSB), Frequency domain, Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), and Discrete Fourier Transform (DFT).
The term digital watermarking was first emerged in 1993, Tirkel introduce two watermarking techniques to hide the watermark data in the images [1].In recent years digital media are gaining widely popular, and their security related issues are becoming greater importance. The protection and
