How to Watermark a Pseudorandom Function

How to Watermark a Pseudorandom Function

A software watermarking scheme can embed a message into a program while preserving its functionality. The embedded message can be extracted later by an extraction algorithm, and no one could remove it without significantly changing the functionality of the program. Prior constructions of watermarking schemes with provably security mainly focus on watermarking pseudorandom functions (PRFs). In this talk, I will introduce how to construct watermarking schemes for PRFs, which are provably secure under some widely accepted assumptions and have desirable properties like collusion resistance and public-key security.
