In this paper we present a model-based image steganography method in discrete wavelet
transform (DWT). This method is based on the human visual system model. The proposed …

Image watermarking has become an important tool for intellectual property protection and
authentication. In this paper a watermarking technique is suggested that incorporates two …

In this paper, an enhanced symmetric hybrid digital cryptosystem method based on jigsaw
transform, digital domain watermarking using discrete cosine domain is proposed. To further …

This paper presents a new and comparatively secure watermarking technique, in the
frequency domain. Our scheme deploys a local ring-based substitution box (S-box). The …

In this paper, a multibit, multiplicative, spread spectrum watermarking using the discrete
multiwavelet (including unbalanced and balanced multiwavelet) transform is presented …

Securing data in telemedicine applications is extremely essential and therefore it is
mandatory to develop algorithms which preserve the data transmitted. Steganography …

In this paper, the concepts of vector quantization (VQ) and association rules in data mining
are employed to propose a robust watermarking technique. Unlike ordinary or traditional …

We are reporting the results of an enhanced performance human face detection using HSV
color model without sacrificing the speed of detection. The proposed algorithm has been …

The digital products are copied and transmitted widely with the development of Internet
rapidly. The copyright protected, the authenticity and the integrality authenticated are …

This paper presents a new approach for non-blind watermarking of still gray level images in
contourlet domain. It uses the human visual system (HVS) characteristic, and an innovative …
