Empowering people to express themselves in global communities, social networks became almost indispensable for exchanging user-generated content. User profiles are essential elements of social networks. They represent their members, but also disclose personal data to companies. W3C’s WebID offers an alternative to centralized social networks that aims at providing control about personal data. WebID relies on trusting the systems that host user profiles. There is a risk that attackers exploit this trust by tampering user profile data or stealing identities. In this paper, we therefore propose the IronClad approach. It improves trustworthiness by introducing tamper-evident WebID profiles. IronClad takes protective measures to publicly discover malicious manipulation of profile data. We exemplarily implement IronClad in an existing WebID identity management platform known from previous work.
