本文主要就未经授权使用的适用于数字化高效调查状态的新兴技术的合宪性进行分析。特别是,车辆自动识别,监控摄像机与面部识别,和第三方数据库。总的来说,根据当前第四修正案未经授权使用监控技术并不等于搜查。这些技术不提供给工作人员任何超感官的能力,但仅仅是提高执法调查的效率。 This article mainly analyzes the constitutionality of emerging technologies that are not authorized for use in digital, efficient state-of-investigation. In particular, vehicles are automatically identified, surveillance cameras and facial recognition, and third-party databases. In general, the unauthorized use of monitoring techniques under the current Fourth Amendment does not mean that the search was conducted. These technologies do not provide any super-sensory capabilities to staff, but merely increase the efficiency of law enforcement investigations.
