我们提出了一种新的技术，可以防止非法使用的对象，没有水印的图像。该技术使用不可见地包含水印的照明。由于物体的照明包含水印，因此由相机拍摄的物体的图像也包含水印，并且可以通过图像处理来提取该水印。我们进行了实验，其中一位二进制数据被嵌入在一个块，由8 × 8像素使用DCT产生的最高频率分量的相位。实验结果表明，嵌入数据可以非常准确地读出，达到100%的多数方法，使用三个数据嵌入在三个分开的块。实验结果证明了该技术的可行性。
We propose a novel technology that can prevent the illegal use of images of objects that do not have watermarking. This technique uses illumination that invisibly contains the watermarking. As the illumination for the object contains watermarking, the image of the object taken by the camera also contains watermarking and this watermarking can be extracted by image processing. We conducted experiments where one-bit binary data were embedded in one block that consisted of 8 times 8 pixels using the phase of the highest frequency component generated by DCT. The experimental results revealed that embedded data could be read out extremely accurately, reaching 100% with the majority method, which used three data embedded in three separated blocks. The experimental results demonstrated the feasibility of the technology we propose.
