本論文的主要目的是用一套硬體架構去實現浮水印嵌入法則。採用的法則是Hadamard Transform法則，與其他法則相比，此法則解決了其他法則有不可逆和會受到圖片種類而影響嵌入數量的問題，同時計算複雜度也不高，計算上較方便。
本論文將會以硬體架構去實現浮水印嵌入法則，在許多應用中，我們希望能夠即時的嵌入浮水印，在軟體中，嵌入所花的時間和想要嵌入的浮水印bits數成正相關，而此時用硬體處理的好處是執行時間不會因為想要嵌入的浮水印bits數而有太大變化，同時資源消耗方面也不太受影響，可在有限的時間內快速的嵌入浮水印。在其他以VLSI架構來嵌入浮水印的論文中，大多有嵌入完後不可逆的問題，或是可能無法為圖片提供全覆蓋保護，而在本論文中則解決了上述問題。綜合上述提到的觀點，本硬體架構具備低複雜度、處理速度快、可使嵌入浮水印後的圖片還原至原圖，以及提供全圖片覆蓋保護的優點。
