Comparison of digital watermarking techniques abstract: digital watermarking is the method of hiding digital data in any form of multimedia data such as image, audio, video, etc digital watermarks are used for verifying the integrity and authenticity of multimedia data and also used to prevent fraud and forgery. Digital watermarking 1 digitalwatermarking 2 contents what is dwm applications classification working attacks advantages and disadvantages techniques. Digital watermarking techniques derive from steganography, which means covered writing (from the greek words stegano or covered and graphos or to write) steganography is the science of communicating information while hiding the existence of the communication.

In this paper various techniques used for digital watermarking such as least significant bit (lsb) technique, discrete cosine transform (dct), discrete wavelet transform (dwt), and back propagation neural network (bpn) algorithm have been compared these techniques are used to embed and extract a .
