云计算时代对数字视频版权保护提出了新的要求,除了具有安全性、鲁棒性、不可感知性、实时处理性、随机检测性和盲检性,同时还要与视频编码标准相结合,考虑水印容量。通过分析云计算环境中数字视频版权保护的特点,有针对性的阐述了一种基于MPEG_4的视频数字水印的嵌入、提取和检测算法。经实验证明:该算法具有很好的鲁棒性。
雲計算時代對數字視頻版權保護提齣瞭新的要求,除瞭具有安全性、魯棒性、不可感知性、實時處理性、隨機檢測性和盲檢性,同時還要與視頻編碼標準相結閤,攷慮水印容量。通過分析雲計算環境中數字視頻版權保護的特點,有針對性的闡述瞭一種基于MPEG_4的視頻數字水印的嵌入、提取和檢測算法。經實驗證明:該算法具有很好的魯棒性。

Cloud computing era puts new requirements to digital video copyright protection.The requirements include not only security, robustness, imperceptibility, real-time processing, random detection and blind detection, but also combining with video coding standard and simultaneously considering the watermark capacity. By analyzing the characteristics of cloud computing environment for copyright protection of digital video, this paper presents a algorishm of embedding, extraction and detection for digital video watermarking based on MPEG_4. The experiment results show that the algorithm has good robustness.
