    Abstract: Digital watermarking is a style through which we can achieve the authentication for images,videos
and texts. The functions of watermarking are not only for authentication purpose but we have another major
issue is a security of the documents this can also be achieved by watermarking, basically, we have secondary
image that covers the original image to make it secure. Today there are many people need a safe and protected
method to expand information. To achieve the authentication of data as well as the data security, we presents
a comparative study on the different types of attacks for digital watermarking method.
