Abstract :
This paper will have a brief look to digital watermarking in images. At first, we have a look to different scopes in the field of data hiding, which are steganography and watermarking. Also, we talk about their difference. Watermarking system is introduced and the benefits of its usage are talked. Requirements of watermarking system are another section of proposed study, which introduces the security, imperceptibility, capacity and robustness as the essential factors of watermarking system. Also, a quick survey on watermarking techniques with a brief comparison is presented.
