This study proposes a semi-fragile watermark design method for detecting illegally copied 2D barcodes. The proposed method uses real mobile phones for fitness calculation rather than simulation. In addition, we formulate this task as a multi-objective optimization problem to design a commonly usable watermark on various mobile phones.
