A new universal blind steganalysis scheme is presented based on analysing the limitation of Farid s universal blind steganalysis on the dimension of the feature vector,the validity of the single feature,and the correlation of the features.

On the basis of the limitation of Farid s universal blind steganalysis that image features for the classification are too many and have correlations, a new universal blind steganalysis scheme is presented.

The Algorithm of Images Steganalysis and Tamper Authentication;

This paper presents a steganalysis scheme which can effectively attack JPEG steganographic.

A new universal blind steganalysis scheme is presented based on analysing the limitation of Farid s universal blind steganalysis on the dimension of the feature vector,the validity of the single feature,and the correlation of the features.

The improved algorithm can resist RS steganalysis in some degree so that the security of LSB algorithm is improved.

Steganography and steganalysis are of great significance to information security in that they become very important techniques on information war in the internet age.

The proposed method can robustly recognize the component related the functional activation paradigm without any prior information,and achieve blind analysis of functional magnetic resonance imaging(fMRI) data.
