This paper presents a walermarking/fingerprinting system for relational databases. It features a built-in declarative language to specify usability constraints that watermarked data sets must comply with. For a subset of these constraints, namely, weight-independent constraints, we propose a novel watermarking strategy that consists of translating them into(More)
Relational databases watermarking aims at protecting the intellectual or industrial property of a dataset, by applying secret and slight alterations on it. When critical usability constraints of this dataset must be preserved, finding such alterations (watermarks) is a difficult computational task, which is not optimized by the current watermarking systems.(More)
