WebConstructing software watermarking with strong security guarantees has proven di cult. Early works on cryptographic watermarking [NSS99, YF11, Nis13] could only achieve mark-unremovability against adversaries who can only make a restricted set of modi cations to the marked program. The more recent Digital watermarking for relational databases has emerged as a candidate solution to provide copyright protection, tamper detection, traitor tracing, and maintaining integrity of relational data. Many watermarking techniques have been proposed in the literature to address these purposes.
