Web search engines are essential tools for accessing information on the internet, but concerns about privacy arise due to the storage of sensitive user data in query logs. To address this, various private web search (PWS) schemes have emerged, aiming to safeguard user privacy while still providing effective search results. However, there's a lack of clarity on which characteristics are crucial for ensuring web search privacy (WSP) in PWS schemes. It introduces a new PWS scheme employing proxy-query-based query obfuscation, a novel approach in PWS research. By utilizing proxy queries, users can retrieve information from search engines without directly exposing their true queries, enhancing privacy. The second part of this paper focuses on delineating key characteristics of PWS and evaluating modern PWS schemes against these criteria. Through analysis, it becomes evident that only the newly proposed PWS scheme fulfills all identified characteristics. Existing PWS systems are found to be vulnerable to WSP attacks due to their failure to meet all essential PWS characteristics.
