چکیده
|
The watermarking is a method of concealing digital information in multimedia data,namely the host image. discrete wavelet transform (dwt) when joined with discrete cosine transform (dct) and svd deliver powerful digital watermarking image. there are different types of intrusions that either plunder the actual ownership or demolish the appearance. in this paper,the dwt-dct,dwt-svd approach has been proposed to ensure security by concealing the watermark inside the actual image and validate the proprietor’s image. using dwt-dct and low-bit percentage,the watermark image was inserted and abstracted. the dwt-svd hybrid produced very good results. © 2017 universiti putra malaysia press.
