Abstract

Single Sign-On (SSO) technology enables users to access multiple application services using a single identity issued by an identity provider. This significantly enhances user experience and reduces the identity management cost for service providers, leading to its rapid adoption. However, most existing SSO schemes lack effective user privacy protection, which results in potential leakage of identity information and behavioral data. In recent years, various privacy-preserving SSO schemes have been proposed, yet a comprehensive review of privacy protection mechanisms from the perspective of SSO system architecture remains absent. This paper analyzed the technical characteristics, application scenarios, and privacy challenges of synchronous and asynchronous SSO authentication models. The study proposed key evaluation criteria and methodologies for privacy-preserving SSO based on current development trends. Existing privacy-preserving schemes were systematically reviewed, and their design principles and technical approaches were summarized. The schemes were compared and analyzed in terms of privacy, security, and generality to reveal their strengths and limitations. Current research hotspots and critical challenges in SSO privacy protection were outlined, and future research directions were identified to support further studies in this field.
