There are two drawbacks in conventional steganography technology. First, hidden messages cannot be observed by human eyes. Second, decryption process is so complex that it is hard to reach real-time requirements. In this article, it is expected to find a new method, which is simple, fast and secure. Taking these principles into account, we establish a confidential display system based on high refresh rate display. The system consists of a FPGA, a high refresh rate screen and shutter glasses. Under the control of FPGA, useful frames are submerged in a large number of other redundant frames. Useful frames, together with redundant frames, display on the high refresh rate screen. Because of the redundant in-formation's interference, it is difficult for the human eyes to find out the useful information while it's easy to pick up useful information through the high-speed shutter glasses, which can exclude the redundant information.
