Abstract: Recent advances in digital technologies have made alteration of digital multimedia content simple and unnoticeable by human beings. Although digital multimedia content offers numerous advantages such as easy to store, easy to transmit, etc., it has made illegal replication/distribution of digital content easier and highlights the need for digital rights management (DRM). Digital watermarking has emerged as a solution for the copyright protection of digital multimedia content. Digital watermarking hides the owner's information inside the digital multimedia content which can be extracted in future to prove the owner's copyright over the content. In this paper, self-recoverable digital watermarking method is presented to protect the digital images from tampering attacks. Experimental results show that the proposed method is robust against attacks such as cropping, blurring, noising, etc.

Keywords: self recoverable watermarking; digital images; error correction code; ECC; copyright protection; security; tampering resistance; multimedia content; digital content; digital watermarking; attacks; cropping; blurring; noising.
