A Review and Analysis of Keyword Search Technologies for Data Privacy Protection
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.
