Latest Patents

Ahn's latest patent on a steganography method involves a unique apparatus that embeds hidden messages within a video stream, creating a stego video utilizing a generative neural network. This method stands out for its innovative approach of using video as a cover medium, as opposed to traditional images. The process employs a discriminant neural network to ensure that the generated video closely resembles the original cover video, making the hidden information more secure. Furthermore, the system engages in adversarial training to produce a second stego video through a dynamic relationship between the generative and discriminant neural networks. The embedding techniques explored in this patent include pre-embedding, intra-embedding, and post-embedding.

Additionally, Ahn has developed a method for creating high-speed hyperspectral video using a generative adversarial network algorithm. This method captures images from a hyperspectral high-speed camera, forming a three-dimensional data cube that incorporates both spectral and spatial information. By segregating moving objects from the background within these data cubes, Ahn's work significantly improves the accuracy of spectral analysis and enhances the visualization of dynamic processes.
