The method includes dividing user's hidden data into plural partial data and outputs the plural partial data, performing a message-encoding of the plural partial data, modulating the plural message-encoded data into image signal format and outputting plural message signals, generating a synchronization signal for synchronizing the constructively multi-patterned watermark with a two-dimensional translation of an image, generating, plural sub-base patterns using the plurality of message signals modulated into the image signal format, and the synchronization signal, and generating a base watermark that is the constructively multi-patterned watermark, using the plural sub-base patterns. Therefore, the invention increases the payload of the watermark, withstands robustly the two-dimensional translation of an image and general geometric transform of the image through the constructive characteristics of the watermark."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for generating constructively multi-patterned watermark, and apparatus and method for inserting and detecting the watermark using the same","description":"An apparatus and a method for generating a constructively multi-patterned watermark, an apparatus and a method for inserting and detecting the watermark using the same.
