Cognitive Channel Decoding
Improved authentication of images is presented, with additional improved quality of the image in sense of enhanced error correction. The algorithm is based on the idea on synergic effect of channel coding and cryptographic mechanisms used for authentication, e.g. Message Authentication Codes. The algorithm is not limited on image processing, but used for image authentication as a study case. Simulation results show the measure of gained image quality.
