Genetic algorithm and difference expansion based reversible watermarking for relational databases
GADEW is a reversible watermarking technique developed for relational databases. GADEW improves watermark capacity and reduces distortion of watermarked relation. Genetic algorithm (GA) is used to meet optimal criteria for watermark embedding. Robust against tuple and attribute wise attacks, and minimizes false positive rate. Robust against addition, deletion, sorting, bit flipping, and additive attacks.
