Identity Management in the Age of Blockchain 3.0

Since the invention of internet, identity has become a significant aspect for nearly every interaction that occurs online. In this position paper, we demonstrate and discuss current limitations of centralised Identity Management (IdM) systems by drawing from the cases of two of world’s largest biometric ID systems: India’s Unique Identification System Aadhar and China’s Social Credit system, Sesame Credit. This paper explores self-sovereign identity through innovative application from blockchain 3.0. We then identify some key characteristics of blockchain technologies to address the challenges centralised IdM services face and present opportunities for furthering HCI research around de-centralised IdM services to provoke workshop discussion
