Latest Patents

Xianghui Yang holds a patent for a "Method of digital watermark and the corresponding device, and digital camera which can append watermark." This invention includes a digital camera equipped with a watermark-adding device. The device comprises several components, including a signal value obtaining device, a bits dividing device, an altered regions initializing device, an eigenvalue calculating device, an encrypting device, and a watermark embedding device. The bits dividing device is responsible for segmenting the data that records each pixel point of the digital image. It divides this data into bits for calculating the eigenvalue of the image, bits for hiding the watermark, and bits for locating altered regions. The altered regions initializing device can set all the data of the bits for locating altered regions to either 0 or 1. The eigenvalue calculating device computes the eigenvalue of digital signals, while the encryption device encrypts this calculated eigenvalue. Finally, the watermark embedding device integrates the eigenvalue information into the digital signals.
