Security of the Medical Media Using an Hybrid and Multiple Watermark Technique

A Hybrid Secure watermarking technique in Telemedicine

For healthcare applications, a hybrid multiple watermarking has been projected in this paper. For authentication and identity purpose, the projected scheme makes use of two watermarks, one in the form of text watermark which includes diagnostic information of the patient and the other image watermark includes the hospital logo. In order to improve the robustness performance of the scheme DWT, D...

A perceptually driven hybrid additive-multiplicative watermarking technique in the wavelet domain

This paper presents a hybrid watermarking technique which mixes additive and multiplicative watermark embedding with emphasis on its robustness versus the imperceptibility of the watermark. The embedding is performed in six wavelet sub-bands using independently three embedding equations and two parameters to modulate the embedding strength for multiplicative and additive embedding. The watermar...

Compressive Sensing Based Multiple Watermarking Technique for Biometric Template Protection

Biometric authentication system is having several security issues. Two security issues are template protection at system database and at communication channel between system database and matcher subsystem of biometric system. In this paper, two level watermarking technique based on CS Theory framework in wavelet domain is proposed for security and authentication of biometric template at these t...

Proposing an effective approach for Network security and multimedia documents classically using encryption and watermarking

Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
