Abstract With rapid development, seed technology, secure transmission of information is very intricate. For harmless and protected transmission of information, digital watermarking can be utilized. Watermarking of advanced images is a system of concealing information; likewise, it gives security of information or distinguishing data in the computerized information. The computerized watermarking process implants a sign into the media without altogether debasing its visual quality. We additionally talk about a portion of the watermarking systems for advanced images inside spatial domain, for example, LSB, patchwork and inside frequency domain DCT, DWT and DFT alongside their examination, favorable circumstances and inconveniences. Keywords: Digital watermarking, spatial domain, least significant bit (LSB), frequency domain, discrete cosine transform (DCT), discrete wavelet transform (DWT), discrete Fourier transform (DFT) Cite this Article Ninny Mittal, Anand Singh Bisen, Rohit Gupta.
