現今使用者大多會將較為機密和私人的資料儲存到雲端,然而在儲存資料的過程中必須經由網路做資料的傳輸,但是透過網路傳遞資料勢必得承受資料遭受竄改之風險,這將導致資料有安全性及正確性上的疑慮。
為了確保資料的正確性及安全性,本研究將資料進行加密,再將更為機密的資料以多層浮水印的形式嵌入其中,最後才透過網路進行資料的傳輸,使得資料及機密資料無法輕易的被破解,大幅度提高了資料的可信度。
本研究使用Hadamard法則進行浮水印的嵌入,且本法則可在資料中嵌入多層浮水印,大量提高了浮水印的資料量,而且本法則的浮水印具有高度的脆弱性,縱使資料只遭受過些許的更動,都會對浮水印造成劇烈的變化。另外本研究也有設計相關的硬體架構,透過Pipeline的架構大幅度提升了電路的時脈。
本法則的多層浮水印架構使得浮水印具有頗為可觀的嵌入資料量,同時浮水印還具備高度的脆弱性,透過檢查浮水印能夠驗證資料是否無誤;在雲端資料的存取過程中,透過運用本法則能夠使資料更為可靠。
