论文摘要
本文旨在调查用于端到端加密系统中内容审核的各种技术。我们评估内容审核的具有挑战性的方面：在确保用户隐私的同时，保持安全平台。我们研究某些内容审核技术的独特特征，例如消息坦率和感知哈希，并强调了它们的局限性。当前实施的内容审核技术在某种程度上违反了端到端加密消息的目标。这导致研究人员开发了补救措施并设计新的安全基础，以使内容适度与端到端加密系统兼容。我们详细介绍了这些发展，分析拟议的研究工作，评估其安全保证，将它们与其他建议的解决方案相关联，并在特定情况下确定适当的改进。
This paper aims to survey various techniques utilized for content moderation in end-to-end encryption systems. We assess the challenging aspect of content moderation: maintaining a safe platform while assuring user privacy. We study the unique features of some content moderation techniques, such as message franking and perceptual hashing, and highlight their limitations. Currently implemented content moderation techniques violate the goals of end-to-end encrypted messaging to some extent. This has led researchers to develop remediations and design new security primitives to make content moderation compatible with end-to-end encryption systems. We detail these developments, analyze the proposed research efforts, assess their security guarantees, correlate them with other proposed solutions, and determine suitable improvements under specific scenarios.
