Video encryption algorithm of content associated key

  • 摘要: 随着计算技术以及视频、显示技术的不断发展,学术以及产业界对新的视频加密算法不断有着更高的要求.通过对现有视频版权保护技术中加密算法不足之处的分析,提出内容关联密钥的概念,并将其运用于视频加密.基于宏块运动矢量预测残差的抽取算法,将视频中敏感数据抽取为密钥,可在10%以内抽取比例下,有效对视频质量进行破坏.为了有效验证该加密算法效果,通过视频质量评估方法峰值信噪比(PSNR)与结构相似度(SSIM)对内容关联密钥算法加密后不同视频内容、不同参数视频进行视频质量评估,证明算法的有效性与一致性,并通过性能分析以及效果对比说明了抽取算法的效果.
