New information hiding technology using invisibly brightness-modulated Light

我们研究了利用包含不可见二进制信息的亮度调制照明将信息嵌入到相机拍摄的物体图像中的技术。我们进行了实验来评估该技术的可行性，并证明了1位二进制数据可以不可见地嵌入到许多小的二维块或一维线中，并且可以准确地读取嵌入的数据。我们还演示了我们可以将深度图嵌入到相机拍摄的图像中，该图像使用物体的照明，其中包含不可见的图案，其特征取决于物体的深度

We studied the technique that could embed the information in the image of the object taken by the camera using the brightness-modulated illumination that contained invisible binary information. We conducted experiments to evaluate the feasibility of the technology and demonstrated that one-bit binary data could be embedded invisibility in each of many small 2-D blocks or 1-D lines and embedded data could be read out accurately. We also demonstrated that we could embed the depth map in the images captured with a camera using illumination for the object that contained invisible pattern whose characteristics depended on depth of the object
