Biography

Norman Sadeh is a Professor in the School of Computer Science at Carnegie Mellon University (CMU). Sadeh has (co-)founded and (co-)directed several groundbreaking graduate programs at CMU. This includes the Privacy Engineering Program (co-founder and co-director,2012-present), the Ph.D. Program in Societal Computing (co-founder and co-director, 2003-2013), and the MBA track in Technology Strategy and Product Management launched jointly by the Tepper School of Business and the School of Computer Science (co-founder and director, 2005-2017). Sadeh's current research interests include cybersecurity, online privacy, Human-AI Interaction, AI governance, mobile computing, the Internet of Things, user-oriented machine learning, language technologies, and semantic web technologies.

Sadeh is well known for his pioneering work on AI-based privacy enhancing technologies, including the development of privacy assistants, the development of automated privacy compliance tools, and the development of NLP-based privacy enhancing technologies. He has also conducted foundational work on modeling people's privacy expectations and preferences and on privacy and security nudging. His work has been credited with influencing the development of privacy-enhancing solutions at companies that include Apple, Google and Facebook/Meta (e.g., more expressive mobile app permissions, background privacy reminders/nudges, privacy dashboards, privacy compliance tools, mobile app privacy labels). Sadeh is the lead designer of CMU's Privacy Infrastructure for the Internet of Things (IoT). Results of his research have also informed privacy policy and activities at regulatory agencies, including the Federal Trade Commission and the California Office of the Attorney General (e.g., mobile app privacy compliance, CCPA privacy opt-out notices, IoT privacy).

Sadeh is also a successful entrepreneur. He was the founding CEO and, until its acquisition, the chairman and chief scientist of Wombat Security Technologies, a company that defined the multi-billion dollar user-oriented cybersecurity market.

This column argues that without AI, adequate privacy has become simply out of reach. This is not because AI is benign; it most definitely is not. Rather, the modern digital ecosystem has evolved to a point where no human, unaided, can understand, monitor, or manage the complexity of today’s data practices.
