Digital Watermarking (DW) is a crucial field for copyrights of a diversity of electronic documents and media. DW is a technique of mixing information into a digital signal (DS). In DW we work on 2 pictures one is for watermark image (WI), which is cover on the first image (secondary image) that offers protection to the picture. It acts as a digital mark, presenting the picture an excellent decision of possession or authentication. DW technique is very inspiring for image authentication (IA) or protection for attacks. This paper a review on DW their classification, application, techniques, attacks and also tampering detection (TD) in DW.
