The MPEG-7 Video Signature Tools for Content Identification

This paper presents the core technologies of the video signature tools recently standardized by ISO/IEC Moving Picture Experts Group (MPEG) as an amendment to the MPEG-7 Standard (ISO/IEC 15938). The video signature is a high-performance content fingerprint that is suitable for desktop scale to web-scale deployment and provides high levels of robustness to common video editing operations and high temporal localization accuracy at extremely low false alarm rates, achieving a detection rate in the order of 96% at a false alarm rate in the order of five false matches per million comparisons. The applications of the video signature are numerous and include rights management and monetization, distribution management, usage monitoring, metadata association, and corporate or personal database management. In this paper, we review the prior work in the field, explain the standardization process and status, and provide details and evaluation results for the video signature tools.
