SimpleMark: Fast Multi-Bit Text Watermarking under f -Divergence Constraints
Benjamin D. Kim, Wanrong Zhang, Weitong Ruan +2
We introduce a framework for multi-bit text watermarking with security defined directly through -divergence from the base language model distribution. Unlike prior approaches th…
Optimal Guarantees for Auditing Rényi Differentially Private Machine Learning
Benjamin D. Kim, Lav R. Varshney, Daniel Alabi
We study black-box auditing for machine learning algorithms that claim R \ 'enyi differential privacy (RDP) guarantees. We introduce an auditing framework, based on hypothesis test…
Scalable Multiterminal Key Agreement via Error-Correcting Codes
Benjamin D. Kim, Daniel Alabi, Lav R. Varshney
We explore connections between secret sharing and secret key agreement, which yield a simple and scalable multiterminal key agreement protocol. In our construction, we use error-co…
Watermarking Discrete Diffusion Language Models
Avi Bagchi, Akhil Bhimaraju, Moulik Choraria +2
Watermarking has emerged as a promising technique to track AI-generated content and differentiate it from authentic human creations. While prior work extensively studies watermarki…
