METHOD FOR EMBEDDING ADAPTIVE DATA FOR IMAGE QUALITY IMPROVEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for embedding the hidden message in the image which maintaining the image quality of an original digital photograph and insuring that a hidden message is made invisible in the image. SOLUTION: This method for improving the embedding of a message in a digital image includes various stages in which a random face carrier is generated, a distributed message generated by entangling the message and the random face carrier and the distributed message is attached to the digital image to form an image where a hidden (confidential) message is embedded. For its improvement, a stage in which the amplitude of the distributed message is modified as the lightness function of the digital image before attaching the distributed message to the digital image is included.
