Keyword:digital semipublic watermarking, cover message
Abstract:The goal of watermarking is to hide message (usually called cover message / CM). In public watermarking scheme, we couldn’t detect watermarking if the watermarking is changed. Besides that, in public watermarking scheme, cover message couldn’t be recovered. Whereas, in private watermarking scheme, to detect watermarking, we should know the private key. Those two schemes have benefits and weaknesses. In semi public watermarking, we could use private key to detect watermark if there are attacks on watermarking and private key could be used to extract cover message. This research aims to generate watermarking from input image. Generate watermarking process will be started from reading color image pixels. After that, the system will compute the stegomessage value will be embedded into digital image. Finally, the system will check the existence of watermarking and extract the message. This software could generate watermarking which will be embedded into input image and check the existence of watermarking. Besides that, the software could generated the detail process of every step in generating and checking watermarking
