Digital watermarking is the effective method of copyright defence. Typically robot-proof watermarks used to secure copyright, and are immune to some deletion or adjustment of protected documents. Fragile watermarks are typically used for content identification and are vulnerable to small alterations. In this paper, we suggest a hybrid watermarking approach that combines a solid and fragile watermark with copyright and material authentication. This mechanism is often resistant to manipulation and to clone attacks at the same time. The relationship between a delicate watermark and a stable watermark is characterised by our involvement. DCT coefficients are used to integrate the values of the watermark.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
