Watermarking-based image authentication robust to JPEG compression


A watermarking-based mostly image authentication theme in the discrete cosine transform (DCT) domain robust to JPEG compression is presented. The binary authentication code is generated from a pseudo-random sequence based on a secret key and a block-dependent feature, protecting the scheme against cut-and-paste attacks. The watermark is embedded in low-frequency DCT coefficients selected by the key key employing a changed quantisation index modulation approach. Before embedding, the chosen coefficients are quantised using the JPEG quantisation matrix for a particular quality issue, protecting the theme against JPEG compression with higher quality factors. Experimental results show that the proposed technique achieves terribly smart watermark imperceptibility and is in a position to detect and locate malicious attacks with sensible precision. Compared with other existing schemes, the proposed algorithm achieves better performance concerning false positive and false negative detection rates and in discriminating malicious attacks from JPEG compression.
