A neoteric chaotic & adaptive watermarking scheme for colored images

Abstract

Today users are enjoying the convenience and advantages of advancement in technology. At present technology provides high quality multimedia processing, acquisition, flexibility, and reliability at significantly lower costs and ease. Digital multimedia documents authentication is thus one of the most important and investigated security applications. Watermarking schemes for the purpose has become evergreen research area. This paper outlines the previous work carried before by the authors and then proposes an image adaptive chaotic algorithm for watermarking of digital mages. The algorithm is tested against both image and text watermarks and found resilient to compression and filtering. © Springer Science+Business Media B.V. 2010.
