digital image information security

基本解釋

This paper mainly discusses the watermark technique applied in information security concerning digital image.
本論文主要探討有關(guān)數(shù)字圖像信息安全中的數(shù)字水印技術(shù)。
Therefore, information security becomes one important problem, and digital image technique has already been useful and needs to be further developed.
因此，信息安全已經(jīng)成爲一個關(guān)鍵而迫切的問題，數(shù)字圖像加密技術(shù)已經(jīng)成爲一項非常實用而又亟待快速發(fā)展的關(guān)鍵技術(shù)。
In the existing method of digital watermark, for embedding watermark information, authors modify more or less original image data through various methods to limit its robustness and security.
已有的數(shù)字水印方法爲了嵌入水印信息都對原圖像數(shù)據(jù)採用各種方法或多或少地進行了脩改，這樣做使其魯棒性和安全性受到限制。
