Abstract: This paper presents a cryptographic protocol for secure account recovery in a privacy-preserving web service, ensuring that users can recover their accounts without revealing personal data to the provider. The proposed system leverages standardized cryptographic techniques, including an oblivious pseudorandom function, to enable secure email-based validation while preventing unauthorized access.

Abstract: In this paper, we run an empirical study with human buyers purchasing products based on ads generated by large language model ‘agents’ to find an increase in misleading advertising and consumer harm. Using our novel economic intervention we demonstrate how to curtail deception by dishonest agentic advertisers while improving the profits of honest ones using truth warrants.
