In this paper we give an introduction to the transition in contemporary surveillance from top down traditional police surveillance to profiling and “pre-crime” methods. We then review in more detail the rise of open source (OSINT) and social media (SOCMINT) intelligence and its use by law enforcement and security authorities. Following this we consider what if any privacy protection is currently given in UK law to SOCMINT. Given the largely negative response to the above question, we analyse what reasonable expectations of privacy there may be for users of public social media, with reference to existing case law on art 8 of the ECHR. Two factors are in particular argued to be supportive of a reasonable expectation of privacy in open public social media communications: first, the failure of many social network users to perceive the environment where they communicate as “public”; and secondly, the impact of search engines (and other automated analytics) on traditional conceptions of structured dossiers as most problematic for state surveillance. Lastly, we conclude that existing law does not provide adequate protection for open SOCMINT and that this will be increasingly significant as more and more personal data is disclosed and collected in public without well-defined expectations of privacy.

公共场所的隐私：社交媒体情报对隐私有什么期望？

在本文中，我们将介绍当代监视从自上而下的传统警察监视到概要分析和“犯罪前”方法的过渡。然后，我们将更详细地回顾开放源代码（OSINT）和社交媒体（SOCMINT）情报的兴起以及执法和安全机构对其的使用。在此之后，我们考虑英国法律目前是否向SOCMINT提供了任何隐私保护。鉴于对上述问题的否定性回答很大，我们将参考《欧洲人权公约》第8条的现有判例法，分析公共社交媒体用户对隐私的合理期望。特别是有两个因素支持在公开公共社交媒体通信中对隐私的合理期望：第一，许多社交网络用户未能将他们交流的环境视为“公共”；其次，搜索引擎（和其他自动化分析）对结构化档案的传统概念的影响是状态监视中最棘手的问题。最后，我们得出结论，现有法律没有为公开的SOCMINT提供足够的保护，并且随着越来越多的公开披露和收集个人数据而没有明确定义的隐私保护，这将变得越来越重要。
