Database watermarking is an important technology mainly used for copyright protection for database. Given the fact that current database watermarking methods cannot resist ordered relation schema mutation (ORSM) attack, attributes labeling based relational database watermarking (ALBWM) algorithm is proposed. Firstly, the definition of ORSM attack is given. Then, through analyzing the fragileness of current watermarking methods under ORSM attack, ALBWM is introduced which includes watermark embed algorithm(ALBWM-EM) and watermark detect algorithm(ALBWM-DT). Experimental results indicate that compared with the traditional watermarking algorithms, ALBWM has better robustness against ORSM attack and does not affect performance.
