上下文完整性被提议以一种不寻常的方式定义隐私。大多数方法都会考虑敏感度级别或“隐私圈”：信息要么是私人的，要么是公共的，并且仅限于特定的代理组，例如私人时的“我的朋友”。相反，上下文完整性指出，传输的任何信息都可能根据其上下文而导致该传输侵犯隐私。我们利用这一理论开发了一种新颖的框架，可以在开放和去中心化的虚拟社区中使用该框架来在社会上加强隐私。本文提出了 PrivaCIAS 框架，其中隐私约束被正式描述为根据上下文完整性理论用于检测隐私侵犯。这个 PrivaCIAS 框架为处理信息的代理提供了社会控制，以便将欺骗性的代理排除在系统之外。
Contextual Integrity has been proposed to define privacy in an unusual way. Most approaches take into account a sensitivity level or a “privacy circle”: the information is said to be either private or public and to be constrained to a given group of agents, e.g. “my friends”, when private. In the opposite, Contextual Integrity states that any information transmitted can make this transmission a privacy violation depending on its context. We use this theory to develop a novel framework that one can use in an open and decentralized virtual community to socially enforce privacy. This paper proposes the PrivaCIAS framework, in which privacy constraints are formally described to be used to detect privacy violations according to the Contextual Integrity theory. This PrivaCIAS framework provides social control to agents that handle the information, so that deceiving agents are excluded from the system.
