Metamorphosis

A New Measure of Watermarking Security Applied on QIMtion (DC-DM QIM) watermarking scheme where the dither vector plays the role of the secret key. This paper presents theoretical and practical computations of the effective key length. It shows that this scheme is not secure as soon as the adversary gets observations in the Known Message Attack context.

Blind Median Filtering Detection Using Statistics in Difference Domainstatistics in the difference domain of images. Extensive simulations are carried out, which demonstrates that the proposed MF detection scheme is effective and reliable for both uncompressed and JPEG post-compressed images, even in the case of low resolution and strong JPEG compression.

Textural Features for Steganalysisted to form a new set of 22,153 features, which are used with the FLD-based ensemble classifier to steganalyze the HUGO on BOSSbase 0.92. At the embedding rate of 0.4 bpp (bit per pixel)? an average detection accuracy of 83.92% has been achieved. It is expected that this new approach can enhance our capability in steganalysis.

This means neither the plain image nor its encrypted version is required for the extraction. The experiments demonstrate the validity and the advantages of our proposed method.

Blind Robust Watermarking Mechanism Based on Maxima Curvature of 3D Motion Data Experimental results show that the proposed watermarking scheme is robust against many possible attacks such as uniform affine transforms (scaling, rotation and translation), noise addition, reordering and cropping.
