Shakespeare Studies and Consciousnessas high embedding capacity while approximately preserving the histogram of quantized DCT coefficients, and the spatial blockiness of stego image has no obvious changes, so the method can resist against histogram-based and blockiness-based steganalysis.

Cytology

A Robust Watermarking Scheme for H.264,rithm to improve the robustness of the scheme; 3) modify the current block by means of a geometry method, which makes the modifying algorithm degrade the video quality as slightly as possible. Experimental results have demonstrated the good performance of our scheme.

A Digital Forgery Image Detection Algorithm Based on Wavelet Homomorphic Filtering,ocalized by the region labeling method. Experimental results demonstrate the proposed method can detect forgery area accurately and reduce the detecting errors when some artificial blur operations are used to create a forgery image.

Exposure Time Change Attack on Image Watermarking Systems, present the results of the ETC attack against one watermarking scheme Iterative Watermarking Embedding. It can be shown that the ETC attack has an important impact on watermark decoding and detection, while not severely reducing the quality of the image.

A Novel Steganographic Algorithm Resisting Targeted Steganalytic Attacks on LSB Matching,sion against existing targeted attacks. The proposed scheme also remains almost undetectable against wavelet absolute moment based blind attack at low embedding rates for never compressed image dataset.
