SBIR Phase II: Authentication of Mobile Video Recordings (MVRs) Based on Real-Time Hybrid Digital Watermarking

这项小型企业创新研究（SBIR）计划第二阶段项目旨在完善和商业化第一阶段开发的认证技术，使数字移动的视频记录（MVR）系统的部署成为可能。由执法部门操作的一支非常庞大的巡逻车队记录涉及与平民接触的事件，每天收集MVR数据。由于与操作当前的模拟、非索引系统相关的惊人成本，存在对计算机化数字MVR技术的压倒性需求。然而，它的部署受到法律的接受的阻碍，因为数字媒体可以很容易地被改变。身份验证通过提供保护MVR内容完整性的有效手段发挥着关键的促进作用。为了利用数字MVR的这一新兴趋势，该公司提出了一项商业化战略，即在经过认证的采集系统中将创新技术打包销售，该系统由数字摄像机和用于动态视频水印、离线MPEG压缩和水印验证的软件套件组成。这款紧凑型低成本采集系统利用现有车载笔记本电脑进行处理和存储，专为满足下一代MVR系统提出的严格操作要求而设计。它与现有的IT基础设施和计算机化的MVR管理系统无缝集成。MVR提供了一种有效的方式来保护执法机构，其官员和他们所服务的公众。MVR认证为全国执法界接受和部署节省成本的计算机化MVR技术提供了一种使能技术。它允许安全地消除与保护MVR内容完整性相关的劳动密集型过程，因为水印是动态完成的，并且不存在MVR数据不受保护的时间窗口。随着配备水印认证技术的数字MVR系统的部署，与操作系统相关的成本将大大降低，从而将节省的资金重新部署到其他执法工作中。在未来三年内，将建立一个全面的国家数字面部数据库，以支持国土安全。作为车内笔记本电脑的一个组成部分，这项技术将作为获取数据以提交给国家数据库的前沿。

This Small Business Innovation Research (SBIR)Program Phase II project is aimed at the refinement and commercialization of the authentication technology developed during Phase I that enables the deployment of digital Mobile Video Recordings (MVR) system. A very large fleet of patrol vehicles operated by the law enforcement community that record events involving contact with civilians collects MVR data daily. Due to staggering costs associated with operating current analog, non-indexing system, there is an overwhelming needs for a computerized digital MVR technology. However, its deployment is hindered by legal acceptance, because digital medium can be easily altered. Authentication plays a critical enabling role by providing an effective means to safeguard the integrity of MVR content. To capitalize upon this emerging trend of digital MVR, the company proposes as a commercialization strategy to market the innovative technology in a package in an authenticated acquisition system, consisting of a digital video camera and a software suite for on-the-fly video watermarking, off-line MPEG compression and watermark verification. This compact and low-cost acquisition system leverages on existing in-car laptop for processing and storage, and is specifically designed to meet stringent operational requirements set forth by next generation MVR system. It integrates seamlessly with existing IT infrastructure and computerized MVR management systems. MVR has provided an effective way of protecting law enforcement agencies, their officers and the public they serve. The MVR authentication provides an enabling technology for the acceptance and deployment of cost-saving computerized MVR technology for the law enforcement community nationwide. It allows for safe elimination of the labor-intensive process associated with safeguarding the integrity of MVR content, because watermarking is done on the fly and there is no time window at which MVR data are ever unprotected. With the deployment of digital MVR system equipped with watermark authentication technology, the costs associated with operating the system will be greatly reduced allowing for the savings to be redeployed to other law enforcement endeavors. Within the next three years a comprehensive national digital facial database will be created to support Homeland Security. As an integral component of the in-car laptop, this technology will serve as the front line in capturing the data for submission to the national database.
