The Fourth Amendment to the US Constitution protects individuals from unreasonable searches and seizures. As technology evolves, courts must examine Fourth Amendment concerns implicated by the introduction of new and enhanced police surveillance techniques. Recent Supreme Court cases have demonstrated a trend towards reconsidering the mechanical application of traditional Fourth Amendment doctrine to define the scope of constitutional protections for modern technological devices and personal data. The current research examined whether public opinion regarding privacy rights in electronic communications is in accordance with these Supreme Court rulings. Results suggest that cell phone location data is perceived as more private and deserving of protections than other types of location data, but the privacy of other types of information recorded on cell phones is valued even more than location data. These results have implications for the police and courts considering how the Fourth Amendment will apply to smart phone technologies.

警方对手机位置数据的监视：最高法院与公众舆论。

美国宪法第四修正案保护个人免受不合理的搜查和扣押。随着技术的发展，法院必须审查第四修正案中引入新的和增强的警察监视技术所牵涉的问题。最高法院最近的案件显示出一种趋势，即重新考虑机械地应用传统的第四修正案学说，以定义现代技术设备和个人数据的宪法保护范围。当前的研究调查了有关电子通信隐私权的公众意见是否符合最高法院的这些裁决。结果表明，与其他类型的位置数据相比，手机位置数据被认为更具私密性，值得保护，但是手机上记录的其他类型信息的隐私甚至比位置数据更受重视。这些结果对于考虑第四修正案将如何应用于智能手机技术的警察和法院产生了影响。
