    本文認為，色度dc系數是魯棒性非常好的參數，因而選擇色度dc系數作為水印信息載體，同時，採用可變的步長選擇部分系數，保證了水印的隱形性；在嵌入水印時，本文採用水印信息「網格劃分」 、各子塊獨立嵌入視頻的方案，由於水印信息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖組當中，即使某一圖組收到一定破壞，也能夠恢復水印信息，使水印的健壯性得到提高；此外，為了提高水印信息的安全性，在嵌入水印信息時，根據用戶輸入的id號和密碼，利用本文構造的混沌系統產生的混沌序列對水印信息進行變換，同時，對每一水印信息比特的嵌入位置也採用了偽隨機序列進行調整，這樣，未授權用戶不能提取水印信息，也難以擦除其中的水印信息，因為嵌入的位置是未知的。
