摘　　要：在现代信息社会,数据隐私保护成为公众关注的焦点。随着互联网用户对个人信息安全的日益重视,信息检索领域的隐私保护研究变得至关重要。隐私保护关键词检索技术旨在在不泄露用户查询意图的情况下,提供安全、保护隐私的检索服务。尽管现有技术在满足基本需求方面取得了进展,但如何在保持效率的同时减少隐私泄露风险,仍是一个挑战。为此,本文对隐私保护关键词检索技术进行了详细回顾,系统地分析了当前主流技术的原理、优势与不足。研究发现,尽管已有技术能够对用户查询进行加密处理,防止敏感信息直接泄露,但在查询模式、访问模式与返回结果之间,仍存在着潜在的隐私泄露风险。针对这一问题,本文提出了一系列改进方向,以增强隐私保护的效果。此外,当前的隐私保护技术在实际应用中面临诸多挑战,这些挑战涉及技术增强、隐私合规等多个方面。通过对隐私保护关键词检索相关前沿技术的融合与创新,有望为解决这些技术问题提供新的思路和方案,推动隐私保护技术向更高水平发展。本文最后对隐私保护关键词检索技术的未来发展方向和创新应用模式进行了展望。In the modern information society,data privacy protection has become a focal point of public attention.As internet users increasingly prioritize personal information security,research on privacy protection in the field of information retrieval has become crucial.Privacy-protecting keyword search technology aims to provide secure and private search services without revealing users'query intentions.Although existing technologies have made progress in meeting basic needs,how to reduce the risk of privacy leaks while maintaining efficiency remains a challenge.For this purpose,this paper provides a detailed review of privacy-protecting keyword search technology,systematically analyzing the principles,strengths,and weaknesses of current mainstream technologies.The study finds that although existing technologies can encrypt user queries to prevent direct leakage of sensitive information,there is still a potential risk of privacy leakage between the query pattern,access mode,and returned results.In response to this issue,the paper proposes a series of improvement directions to enhance the effectiveness of privacy protection.Furthermore,current privacy protection technologies face numerous challenges in practical applications,involving aspects such as technological enhancement and privacy compliance.By integrating and innovating cutting-edge technologies related to privacy-protecting keyword search,new ideas and solutions are expected to resolve these technical problems and promote the development of privacy protection technology to a higher level.Finally,the paper provides an outlook on the future development directions and innovative application models of privacy-protecting keyword search technology.
