Privacy is a complex construct: it is not all or nothing, it is based on control over sharing and reuse, it can depend on context, and is organized in what is called "circles of privacy." Whether to share information is often not a real choice, since sharing is required for basic transactions such as obtaining utilities, services, or products. Furthermore, scale matters, and information asymmetries can quickly create playing fields that are not level. Even in these bleak circumstances, there is reason for hope that we develop socio‐technical systems that better align with our values.

隐私圈

隐私是一个复杂的结构：它不是全部或没有，它基于对共享和重用的控制，它可以取决于上下文，并以所谓的“隐私圈”进行组织。共享信息通常不是一个真正的选择，因为共享对于基本事务（例如获得实用程序，服务或产品）是必需的。此外，规模很重要，信息不对称会很快造成不公平的竞争环境。即使在这些惨淡的环境中，我们还是有理由希望我们开发出与我们的价值观更好地契合的社会技术体系。
