数码相机和拍照手机的日益普及给许多组织和个人带来了对不必要的录音情况的合理担忧。尽管从所有者手中没收这些设备可以遏制敏感信息的获取，但这既不是实际的解决方案，也不是理想的解决方案。在本章中，我们介绍了一个名为 BlindSpot 的系统的设计，该系统可以防止静态和动态图像的记录，而无需捕获设备或其操作员的任何配合。我们的解决方案涉及一个简单的跟踪系统，用于在保护区周围定位任意数量的镜面反射 CCD 或 CMOS 相机镜头。然后，系统将脉冲光射向镜头，扭曲相机记录的任何图像。
The increasing presence of digital cameras and camera phones brings with it legitimate concerns of unwanted recording situations for many organizations and individuals. Although the confiscation of these devices from their owners can curb the capture of sensitive information, it is neither a practical nor desirable solution. In this chapter, we present the design of a system, called BlindSpot, which prevents the recording of still and moving images without requiring any cooperation on the part of the capturing device or its operator. Our solution involves a simple tracking system for locating any number of retro-reflective CCD or CMOS camera lenses around a protected area. The system then directs a pulsing light at the lens, distorting any imagery the camera records.
