Algorithm of image scrambling based on steganography;

BPCS steganography algorithm against statistical analysis;

The Research of Steganography Technique Based on Human Visual System;

Based on zerotrees of the discrete cosine transform(DCT) coefficients,a novel image steganographic algorithm is presented.

Image steganalysis based on statistical characteristics of DCT coefficients and SVM;

LSSVM-based blind steganalysis for JPEG images;

Steganalysis is the attacks to steganography, and its important task is the detection of hidden messages.

Video steganography has the advantage of large embedding capacity, but the security is usually neglected when obtain the capacity.

Moreover,utilizing the principle of steganography based on error-correcting code,the shared keys are introduced to further strengthen the security.

An English text steganography algorithm is presented that can be applied to plain text.

After comparisons,analysis and improvement,an improved authentication scheme is designed,in which a parallel multi-process Tomita algorithm is used,SIP authentication header fields extended and ciphertext steganography system introduced,thus effectively ensuring the security of the application layer.
