I am a PhD candidate in informatics at Pennsylvania State University’s College of Information Sciences and Technology. I am fortunate to be advised by Dr.Tanusree Sharma. My current research interests are usable security and privacy for Web3/Decentralized Internet.

Platform Transparency: With my industry experience, I’ve observed significant challenges in the transparency of data-sharing practices. I am passionate about designing transparent interfaces that foster trust and accountability for building fair and ethical online platforms.

Decentralized Internet: My interest in decentralized systems arises from a desire to explore structures that empower users and reduce platform dominance. These systems align with my broader goal of promoting user autonomy by minimizing the influence of centralized entities.

Building on related concepts, like, decentralized identifiers (DIDs), proof of personhood, anonymous credentials, personhood credentials (PHCs) emerged as an alternative approach, enabling individuals to verify to digital service providers that they are a person without disclosing additional information. However, new technologies might introduce some friction due to users misunderstandings and mismatched expectations. Despite their growing importance, limited research has been done on users perceptions and preferences regarding PHCs. To address this gap, we conducted competitive analysis, and semi-structured online user interviews with 23 participants from US and EU to provide concrete design recommendations for PHCs that incorporate user needs, adoption rules, and preferences. Our study – (a)surfaces how people reason about unknown privacy and security guarantees of PHCs compared to current verification methods – (b) presents the impact of several factors on how people would like to onboard and manage PHCs, including, trusted issuers (e.g., gov), ground truth data to issue PHC (e.g., biometrics, physical id), and issuance system (e.g. centralized vs decentralized). In a think-aloud conceptual design session, participants recommended – conceptualized design, such as periodic biometrics verification, time-bound credentials, visually interactive human-check, and supervision of government for issuance system. We propose actionable designs reflecting users preferences.
