Embodiment Construction

[0096] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0097] Embodiment, user privacy protection method oriented to text retrieval service, refer to figure 1 As shown, the research goal of this embodiment is to design and implement an effective user privacy protection method for text retrieval services, which requires: the existing text retrieval service platform architecture, text retrieval service algorithm, and text On the premise of ensuring the accuracy of retrieval services and not changing the efficiency of text retrieval services, the security of user query privacy and user topic privacy on the untrusted server side is ensured.

[0098]First, a privacy protection framework for text retrieval services is given. It adopts a client-based architecture and constructs several fake queries for users' real queries. Then, confuse real queries into fake queries, and submit them one by one to the server-sid...

Abstract

The invention discloses a text search service oriented user privacy protection method and belongs to the technical field of text search privacy protection. According to the method, when a user carries out text search service, the security of user search privacy and user theme privacy can be ensured at an untrusted server side. A user privacy protection process comprises the following steps of provided a text search service oriented privacy protection framework; defining a text search service oriented privacy protection model based on the privacy protection framework, wherein according to the privacy protection model, a conditional constraint needing to be satisfied by ideal pseudo search is defined formally; and providing a model solution algorithm of the privacy protection model based on the privacy protection framework and the privacy protection model.

Description

technical field [0001] The invention relates to the technical field of text retrieval privacy protection, in particular to a user privacy protection method for text retrieval services. Background technique [0002] With the rapid development of the Internet, the text data on the network continues to explode. Text retrieval service can help users quickly obtain the desired data from massive text data according to the query keywords provided by users, and has become one of the most popular network services. In fact, no longer limited to web page text search, text retrieval has been widely used in various fields of network information services (such as digital library, e-commerce website, enterprise information management, etc.), and has achieved great success. Although text retrieval services can help users to obtain unstructured text data intuitively and effectively, the queries submitted by users may potentially reveal users' private information, thus causing user privacy s...
