Latest Patents

One of Che-Wei Lee's latest patents is a "Color image authentication method based on palette compression technique." This method involves dividing an original image into blocks and applying an interpolation algorithm to create a first image. Each pixel in this first image is then mapped into an index using a palette compression technique, resulting in a second image. The indices are divided into multiple secret values, and a secret sharing algorithm is employed to generate multiple partial shares. A transparent map is created from these partial shares, which is then combined with the original image to produce a lossless image file.

Another significant patent is the "Secret communication method with self-authentication capability." This method divides a secret message into several segments and converts each segment into (k+1) shares, where k is a positive integer. These shares are embedded into a media carrier, and every k shares are selected to compute (k+1) copies in value. The method checks if these copies are identical, allowing the secret message to be displayed if they match. If not, a mark replaces the secret message while preserving the integrity of the unaltered parts. This innovative approach ensures both information hiding and self-authentication.
