Abstract

Today, user attributes are managed at centralized identity providers. However, two centralized identity providers dominate digital identity and access management on the web. This is increasingly becoming a privacy problem in times of mass surveillance and data mining for targeted advertisement. Existing systems for attribute sharing or credential presentation either rely on a trusted third party service or require the presentation to be online and synchronous. In this paper we propose a concept that allows the user to manage and share his attributes asynchronously with a requesting party using a secure, decentralized name system.
