The way that use double watermark technique , and use asymmetric secret key system and a different secret key during watermark checking gives a novel idea to people : different information can be embedded into the image according to different requirement and provided for multiple utilization , because fragile watermark only require the trusted third part to extract and the user is transparent . the robust watermark required the authentication centre to extract the watermark . at the same time , the zero knowledge proof for the author id can be done by the authentication centre , which is the idea of the cryptology authentication and can solve problem of the copyright ownership more effectively 雖然本文對該模型提出的算法并沒有具體實現(xiàn),但是,在同一幅圖像中嵌入魯棒水印與易損水印的雙水印技術(shù),以及采用的非對稱密鑰體制即在水印嵌入過程與水印檢測過程中使用了一對不同的密鑰,可為人們提供一個新的思路:由于易損水印只需通過可信任第三方提取,對用戶是“可見”的,因此可根據(jù)需要嵌入不同的信息,多方利用;魯棒水印的提取需要認(rèn)證中心提取,同時可由認(rèn)證中心對商家身份進(jìn)行的零知識驗證,體現(xiàn)了密碼學(xué)的認(rèn)證思想,更能解決版權(quán)糾紛的所有權(quán)問題。
On this basis , according to water consumption mechanism and process of crops , the relationships , relative influence and effect transferring between various technology on water saving are fully considered . the calculating method of water saving potentialities on basis of the multiple utilization of water resources in irrigated regions is studied . the calculating model on water saving potentialities is set up 在此基礎(chǔ)上,根據(jù)農(nóng)作物耗水機(jī)理和耗水過程,充分考慮各種節(jié)水技術(shù)間的相互關(guān)系、相互影響和效應(yīng)傳遞,研究基于灌區(qū)水資源綜合利用的節(jié)水潛力計算方法,建立節(jié)水潛力計算模型,結(jié)合對不同階段灌區(qū)節(jié)水技術(shù)發(fā)展水平的預(yù)測,定量計算黃河下游引黃灌區(qū)不同水平年的節(jié)水潛力。
