In this dissertation we make a study of subliminal channels that conclude the progress, the application, the model, the construction, the stego - key, the capacity, the security, the way to realize subliminal - freeness, and so on
本文對閾下通道技術進行了比較全面的總結和研究，包括閾下通道的發展狀況，應用前景，閾下通道的模型，構造方法，隱匿密鑰，容量，安全性以及封閉方法等。 -
The proposed adaptive watermarking scheme enables more energy of watermark to be embedded with imperceptibility, so the stego mesh can be resilient to higher intensity of attacks than with traditional schemes
這使得本演算法能夠在嵌入的水印信息不可見的前提下嵌入更大能量的水印，從而保證水印隱藏對象能夠承受更大強度的攻擊。 -
The concept of stego - key exchange is first presented. some conditions and a basic protocol of realizing it are first discussed. then a known - secret stego - key exchange scheme and some unknown - secret stego - key exchange schemes are designed
首次對閾下通道中的隱匿密鑰協商的概念、實現條件和基本協議進行了討論，並設計了已知秘密的隱匿密鑰協商方案和幾個未知秘密的隱匿密鑰協商方案。 -
Then a further conclusion is testified that if the cover and the stego - object are acquainted with the attackers then the security of the system is spoiled
並進一步證明了，若隱秘載體和隱秘對象都為攻擊者所知，則隱秘通信系統不安全。 -
According to common multimedia earners in the internet, the static images are selected as stego carriers. at first, beginning with typical method in special domain lsb ( least significant bit ), the relative tests are developed, and the reasonable results are obtained
考慮到網路上最常用的多媒體載體，我們選取靜態圖像作為信息隱藏的載體，從空域中的典型演算法? ?最不重要位（ lsb ）方法入手，開展相關的試驗工作並得一些重要結果。 -
In order to adapt the scheme to both the color image and the gray image, while embedding the watermarking into the image, the scaling factors are determined by the local luminance feature and texture features of the image. it can improve the embedding strength and the watermarking robustness. from the experimental results, the stego - images are extremely robust to common image processing such as median filter, jpeg compression and denoising after adding the stochastic noises
2 、提出了一種新的基於小波變換和紋理特徵的數字水印演算法，該演算法依據從圖像小波域提取出的紋理特徵來選取水印的嵌入位置，較好地利用了圖像的紋理區域，既能掩蔽較多的噪聲，又能較好地抵抗jpeg壓縮等一般性攻擊，調節了數字水印技術中存在的不可見性與魯棒性之間的矛盾。 -
Give precise criterions and descriptions of some important concepts and disposals of data - hiding technique such as cover, stego - object, hiding information, data embedding, data extraction, stego - key, stego - analysis, insensibility, covert communication, digital watermarking, robustness and etc. then propose a general mathematical model of data hiding which cover most models proposed in other papers and establish the basis for further theory analysis
本論文獨立完成的主要成果有： （ 1 ）對信息隱藏技術中的一些重要概念和處理給出了準確的規范和描述，主要有隱秘載體、隱秘對象、秘密信息、數據嵌入、數據提取、隱秘密鑰、隱秘分析、不可感知性、隱秘通信、數字水印、魯棒性等。
