A Reversible RIE Based Watermarking Scheme

Abstract

Today people are more interconnected with Internet ever before. Internet not only brought advantages, it also brings security threats, cyberattacks, phishing, etc. To mitigate cybercrimes governments are enforcing cyberlaws. In this process authentication of digital objects are essential. To provide authentication many watermarking schemes are proposed. Among edge based watermarking schemes special category because of low distortion while watermarking. However, present edge based watermarking scheme are suffering from smoothing effect and also reversibility is an uncertain parameter. In this paper we are proposing a Reference Image and Edge (RIE) based watermarking scheme to overcome smoothing effect problem in existing edge based watermarking schemes. RIE watermarking scheme also consider cover content information while embedding watermark pattern. Compared to existing edge based data hiding schemes proposed RIE watermark scheme improves visual perception with more or less same embedding capacity.
