Reversible Watermarking Using Prediction Error Histogram and Blocking,sed by arithmetic coding as a part of overhead information. Comparing with the existing spatial domain reversible watermark methods, the proposed method can achieve much better PSNR value at the high embedding rate. Experimental results prove the effectiveness of the proposed watermarking scheme.

Ternary Data Hiding Technique for JPEG Steganography,fied matrix encoding (MME). The proposed methods were tested with steganalysis method proposed by T. Pevny and J.Fridrich. The experimental results show that the proposed method has less detectability compared to MME (modified matrix encoding).

Kontext: Die Ausgangsbasis der Untersuchungpropose a novel method to detect potential JPEG compression history in bitmap images using the PMF that has been developed. We show that this method outperforms a classical approach to compression history detection in terms of effectiveness. We also show that it detects history with both independent JPEG group (IJG) and custom quantization tables.

The experimental results demonstrate that the proposed algorithms have great robustness against various imaging attacks.

Experimental results have shown that that RLRN features extracted from chroma channels provide much better performance than that extracted from R, G, B and luminance channels.

Post-processing is involved to get final localization result. The experimental results prove the effectiveness of our proposed method.

The watermarked signals are perceptibly similar to the original one. Comparing with the previous time-domain watermarking scheme?[1], the proposed watermarking method is more robust against additive noise, MP3 compression, low-pass filtering, etc.
