Credential sharing is a critical mechanism for building trust, protecting privacy and improving collaboration efficiency in modern information systems. However, conventional credential management systems often rely on centralized management, which results in single point of failure and lack of user control over credentials. Moreover, traditional credential sharing mechanisms can easily lead to excessive disclosure of user privacy while ensuring credibility. To address these challenges, this paper proposes SelDUVCS, an adaptable system for verifiable credential sharing with selective disclosure, which minimizes sensitive information exposure through selective disclosure and enhances the system’s privacy protection capability. By integrating vector commitment techniques with blockchain technology, SelDUVCS ensures verifiability of disclosed credentials while significantly reducing privacy exposure and eliminating reliance on centralized entities. Our experimental evaluation demonstrates that SelDUVCS achieves substantial improvements in privacy protection and credential verification efficiency, offering a viable alternative to traditional credential sharing frameworks.
