A Secure Semi-Fragile Watermarking for Image Authentication Based on Integer Wavelet Transform with Parameters,” Third Australasian Information Security Workshop

, 2008
Semi-fragile watermark fragile to malicious modifications while robust to incidental manipulations is drawing many attentions in image authentication. However, watermark security has not received enough attention yet.

Semi - Fragile Watermarks für digitale Bilder

, 2018
This Masters thesis describes the process of implementing a semi-fragile watermark, examining especially the usage of the wavelet transform as well as the creation of pseudo random numbers to enable secure encryption and embedding of a watermark. Based on the realized application, experiments with different sorts of image manipulations were conducted ...
