An information hiding system based on high frame rate video

Abstract

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.
