摘要：This paper proposes a novel pixel based fragile watermarking scheme in spatial domain by which onecan easily identify the alteration in every pixel of the images accurately and scheme is also protected by user definedsecret key. Proposed watermarking algorithms are able to increase PSNR value and also have low complexity ofalgorithms. These algorithms also work on color images efficiently, if all three RGB planes are treated as separate one.Proposed scheme achieves PSNR value up to 44.09 dB and also able to achieve 100% efficiency in some cases, whichis good enough. Experimental results show that proposed watermarking algorithms give significant responses in findingvarious types of temporization attacks.
