Governing LLM Models with Democratic Decision-Making

This project Inclusive.AI introduces a paradigm for diverse stakeholders of AIto collaboratively address social, technical, and political challenges. This is a step foward to democratize AI governance by ensuring participation in decision-making regarding AI models and behaviors through a Decentralized Autonomous Organization (DAO) mechanisms. This includes various decision-making schemes like quadratic, ranking, and weighted voting, with both equal and differential voting powers. Leveraging blockchain technology, Inclusive.AI promotes transparency and prevents manipulation, enhancing user involvement in governing large language models and shaping future policies.

Visual Privacy for Blind Users

This line of work proposed new method of dataset creation and designing AI for underserved group (e.g. blind users)in ethical way. A novel contribution of this work is an addition of new data creation/collection method for ethical AI development pipeline - opting for props objects to create dataset with blind users; integrating diverse expertise areas like accessibility, privacy, and computer vision to ensure essential criteria like content diversity and category representation as well as privacy/security of data collection/creation to foster AI advancements. Dataset comprises 728 images and 728 videos from 14 private categories, all captured by 26 visually impaired individuals. Furthermore, this work contribute an initial prototype and evluation of blind users with design insights of how blind users would like to obfuscate private content in different contextual scenarios, complemented by a Wizard-of-Oz setup offering human-generated guidance.

Decentralized Application Usability, Security & Accessibility

This line of work includes usable privacy and security addressing investigating the context of Blockchain and decentralized application for addressing issues around both end users and developers' points of view. One project presented at Usenix 23 dedicated to improving smart contract development practices and designing tools for secure coding of smart contracts. Meanwhile, another project focuses on exploring the security and usability aspects of web3-based applications, presented at SOUPS 23, including crypto wallets and DeFi applications. Another noteworthy project involves addressing usability and security concerns by implementing cryptographic protocols like MFKDF in the context of crypto wallets with a potential to benefit various decentralized applications These project applied ranges of method including, system developemt, randomized control experiment, user interview, surveys to understand users expectation, preferences in making actionable tooling/application. As a result of the efforts, we have developed two exceptional systems: the Ciao wallet with the MFKDF scheme and the i-Wallet with enhanced usability and accessibility features.

Privacy In Global South

This line of work is motivated by the cultural, economic, and development differences in the Global South, where the Western definition of privacy is often not applicable. As a result of this project, we found novel user mental models of targeted ads based on mobile app permissions and excessive AI usage. People from Global South often preferred ad control over transparency. Another series of project under this line of work involves exploring and designing ad technology, emerging crypto technology, AI, etc, and technologies used in crisis situation, such as COVID-19.

Privacy Principle & Regulation

Data is a valuable asset for organizations in data-driven economies, but without effective measures, data misuse can negatively impact end-users. The 2018 GDPR gives individuals control over their personal data. This project aims to explore users' understanding of data minimization in search engines, factors influencing their decision to share search data, and their perspective on how data minimization should work in AI System.
