JPEG-Compatibility Steganalysis that Distinguishes Embedding Changes from Recompression Artifacts
《China Communications》2014年第9期173-182,共10页MA Xiaojing LIU Jiaojiao ZOU Deqing JIN Hai 
This work was supported in part by National Natural Science Foundation of China，National 973 Basic Research Program of China，the Fundamental Research Funds for the Central Universities,HUST
JPEG-Compatibility steganalysis detects the presence of secret message embedded in the JPEG decompressed images and estimates the embedding rate. We propose a JPEG-Compatibility steganalysis algorithm that estimates t...

A SVM Based Text Steganalysis Algorithm for Spacing Coding被引量：2
《China Communications》2014年第A01期108-113,共6页YANG Yu 
the National Natural Science Foundation of China under Grant No.61170269,No.61170272,No.61202082,No.61003285,and the Fundamental Research Funds for the Central Universities under Grant No.BUPT2013RC0308,No.BUPT2013RC0311
Group distance coding is suitable for secret communication covered by printed documents. However there is no effective method against it. The study found that the hiding method will make group distances of text lines ...

Game Theory Based False Negative Probability of Embedded Watermark Under Unintentional and Steganalysis Attacks被引量：1
《China Communications》2014年第5期114-123,共10页HU Ziquan SHE Kun WANG Jianghua TANG Jianguo 
supported by the National Natural Science Foundation of China（No. 71020107027）; in part by the Doctoral Startup Fundation of Xinjiang University of Finace and Economics
Steganalysis attack is to statistically estimate the embedded watermark in the watermarked multimedia,and the estimated watermark may be destroyed by the attacker.The existing methods of false negative probability,how...
