基于圖像特征的易損水印技術(shù)
A novel fragile watermark technique based on image feature
-
摘要: 該文在 Yeung-Mintzer(1997)的方法基礎(chǔ)上提出了一種新穎的易損水印技術(shù)。為解決原算法存在的安全問(wèn)題,提出利用基于圖像特征的混沌密鑰控制易損水印的嵌入。理論分析和實(shí)驗(yàn)結(jié)果證明該算法可以有效地抵制由原算法所產(chǎn)生的攻擊問(wèn)題。由于水印在空域逐個(gè)像素地進(jìn)行嵌入,所提出的算法具有良好的局部修改檢測(cè)性能。

Abstract: In this paper, a novel fragile watermark technique is proposed, which is based on the method of Yeung-Mintzers (1997). To resolve the existing security problem, a chaotic key which is based on image feature is used to control the embedding of fragile watermark. Theoretical analysis and experimental results demonstrate its effectiveness in resisting possible attacks. And because the watermark is embedded in pixel-wise order, the technique has good ability of detecting local alterations. -
