Abstract :
Digital image processing technology presents new challenges for the security of the image information, which makes image authentication as a problem to be addressed. Digital watermarking plays an important role in multimedia information security. This paper proposed a dual watermarking method to do tamper location and self-recovery, which utilizes self-embedding technology to hide eigenface into the low frequence sub band LL to restore the tamper region. Experimental results show the availability of the proposed algorithm.
