The growth of computernetworks has boosted the growth of the information technology sector to agreater extent. Thus the digital information which includes images, videos,text etc is readily available to anyone. At the same time care is taken toprevent the unauthorized use of the images commercially. To satisfy these needowners moved towards watermarking. In his paper the embedding technique forwatermarking is presented based on LSB & DCT transforms. Here we classifythe techniques based on different domains in which data is embedded. The surveyis limited to images only.
