描述了一种用于使用数字水印来验证视频内容完整性的改进系统。使用数字签名的当前验证系统不能区分攻击和常规修改（诸如MPEG和MPEG编码），并且因此是针对对保存在存储服务中的内容的实际威胁的不合适的对策。该验证系统通过提取嵌入在内容本身中的时间码和头哈希值并将其与实际内容进行比较，将对视频内容的攻击与常规修改区分开来，使其非常适合于内容存储服务。评估表明，该系统比目前使用数字签名方案的系统更有效，并且可以由使用存储的视频内容的各种应用程序使用
An improved system is described for verifying video content integrity using digital watermarking. Current verification systems using the digital signature are unable to distinguish between attacks and regular modifications such as resizing and MPEG encoding and are thus unsuitable countermeasures against actual threats to content kept in storage services. The proposed verification system distinguishes attacks against video content from regular modifications by extracting timecodes and header hash values embedded in the content itself and comparing them with the actual ones, making it well suited for content storage services. Evaluation showed that the system is more effective than a current one using the digital signature scheme and that it can be used by a variety of applications using stored video content
