Based on the classification of images, this paper gives out four digital image steganography techniques which have good conceal effect, including low - three - bits hiding strategy, odd - even of hypo - low bit hiding strategy, deviation of adjacent - field hiding strategy and self - adaptive deviation of adjacent - field hiding strategy. on digital watermarking aspect, this paper gives two blind watermarking strategies which have good conceal effect and high robustness, they are single - watermarking strategy based on minimal - value exchanging and multi - watermarking strategy which hides the same watermark copy on the different parts of an image
在對圖像進行了分類的基礎上，本文給出了四個具有較好掩密效果的數字圖像隱寫策略，包括低三位隱藏策略、次低位奇偶策略、鄰域方差策略和自適應鄰域方差策略；在數字水印方面，提出兩個掩密效果好且魯棒性較高的數字圖像盲水印策略，分別為基於最小值交換法的單一水印策略和嵌入同一水印多個副本的多水印策略。
