服务匹配是基于面向服务架构（SOA）的系统运行中的一个重要过程。在此过程中，将使用来自服务提供商和请求者的信息。如何在撮合过程中保护参与方的隐私是一个挑战。本文提出了一种隐私保护服务匹配方法，以支持基于语义的服务匹配并避免隐私泄露给不可信方。该方法使用态势感知访问控制（SA-AC）机制，通过建模、指定和执行 SA-AC 策略来确保私人信息的适当披露和使用。它为基于 SOA 的系统中的服务提供者和请求者提供了一种以所有者为中心的机制，以在服务匹配过程中保护他们的私人信息。
Service matchmaking is an important process in the operation of Service-Oriented Architecture (SOA) based systems. In this process, information from both service providers and requestors are used. How to protect the privacy of participating parties during the matchmaking process imposes a challenge. In this paper, a privacy- preserving service matchmaking approach is presented to support semantic-based service matchmaking and avoid privacy leakages to untrusted parties. The approach uses situation-aware access control (SA-AC) mechanism to ensure the appropriate disclosure and use of private information by modeling, specifying and enforcing SA-AC policies. It provides an owner-centric mechanism for both service providers and requestors in SOA-based systems to protect their private information during service matchmaking.
