Table 3 Comparison with existing state-of-the-art works in terms of watermarking security and robustness. Watermark security consists of preventing access to the original watermark and verifying its authenticity, and robustness refers to the performance under a quantum bit-flip channel. Italics are our results, bold are the best results while underlining is the second best. DCI stands for detectable copyright infringements.
