This Small Business Innovation Research (SBIR) Phase I project is aimed at developing an authentication technology that enables the deployment of a digital Mobile Video Recordings (MVR) system. MVR data are collected daily by a very large fleet of patrol vehicles operated by the law enforcement community across the country that record events involving contact with civilians. Due to staggering costs associated with operating current analog, non-indexing systems, there is an overwhelming need for a computerized digital MVR technology. Its deployment, however, is hindered by legal acceptance, because a digital medium can be easily altered. Authentication plays a critical enabling role by providing an effective means to safeguard the integrity of MVR content. The objective of this research project is to develop a prototype for real-time MVR authentication software, based on a novel, hybrid watermarking algorithm, that integrates seamlessly with existing digital infrastructure. This algorithm is specifically designed to meet stringent operational requirements set forth by next generation MVR system. It achieves progressively varying robustness in one single watermark by means of error-correcting signature coding and rate-distortion guided bit embedding. It combines fragile watermark's ability to localize content tampering and robust watermark's ability to characterize the severity of content alteration.The MVR authentication, envisioned in this SBIR project, provides an enabling technology for the deployment of a digital MVR system for law enforcement agencies across the country that is more effective and much less costly to operate than the current analog system. The company's technology is inspired by and modeled after a set of realistic and specific requirements of the MVR program of the New Jersey (NJ) State Police, and its software-only solution is designed to integrate easily and seamlessly with its digital infrastructure. It provides a secure and economical mechanism for safeguarding MVR content integrity that is minimally invasive to the daily routines of patrol officers and MVR administrators. This NJ State Police and similar agencies across the country can easily adapt this technology so as to realize enormous cost saving through the deployment of a digital MVR system.

这个小型企业创新研究（SBIR）第一阶段项目旨在开发一种认证技术，使数字移动的视频录制（MVR）系统的部署成为可能。 MVR数据每天由全国各地执法部门运营的一支非常庞大的巡逻车队收集，记录涉及与平民接触的事件。 由于与操作当前模拟、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认可的阻碍，因为数字媒体很容易被改变。 身份验证通过提供有效的手段来保护MVR内容的完整性，发挥着关键的支持作用。 本研究项目的目标是开发一个原型的实时MVR认证软件，基于一种新的，混合水印算法，与现有的数字基础设施无缝集成。 该算法专为满足下一代MVR系统提出的严格操作要求而设计。 通过纠错签名编码和率失真引导的比特嵌入，在一个水印中实现了渐进变化的鲁棒性。 它结合了脆弱水印定位内容篡改的能力和鲁棒水印表征内容篡改严重性的能力。SBIR项目中设想的MVR认证为全国各地的执法机构部署数字MVR系统提供了一种使能技术，该系统比当前的模拟系统更有效，运行成本更低。 该公司的技术受到新泽西州警察局MVR计划的一系列现实和具体要求的启发和模仿，其纯软件解决方案旨在轻松无缝地与其数字基础设施集成。 它提供了一个安全和经济的机制，以保障MVR内容的完整性，这是最低限度地侵入巡逻人员和MVR管理员的日常工作。 新泽西州警察局和全国各地的类似机构可以很容易地适应这项技术，以便通过部署数字MVR系统来节省大量成本。
