A robust, secure and imperceptible image watermarking using DWT-SVD and encryption

الملخص EN

Digital Watermarking is one of the techniques to hinder the unauthorized use of digital media.

This technique can help the protection of proprietorship rights toward ensuring the copyright information and authentication in a networked environment.

Inspired by combining Discrete Wavelet Transform (DWT) with modification of Singular Value Decomposition (SVD).

Digital image watermarking technique based on the encryption algorithm is proposed in the present work in order to improve the robustness, security and the imperceptibility.

The watermark image is encrypted by using Advanced Encryption Standard (AES) encryption technique with a secret key and then transformed the original (host) and watermark images using DWT and modified SVD for embedding the encrypted watermark in the high frequency sub band (HH) of the original (host) image.

The experimental results show that the proposed method is superior from where robustness, imperceptible and security as compared with some related methods.
