Watermarking Images in the Frequency Domain by Exploiting Self-Inverting Permutations
《Journal of Information Security》2013年第2期80-91,共12页Maria Chroni Angelos Fylakis Stavros D. Nikolopoulos 
In this work we propose efficient codec algorithms for watermarking images that are intended for uploading on the web under intellectual property protection. Headed to this direction, we recently suggested a way in wh...

Comparative Evaluation of Semi Fragile Watermarking Algorithms for Image Authentication被引量：2
《Journal of Information Security》2012年第3期189-195,共7页Archana Tiwari Manisha Sharma 
Technology has no limits today;we have lots of software available in the market by which we can alter any image. People usually copies image from the internet and after some changes they claim that these are their own...

Digital Image Watermarking Based on Mixed Error Correcting Code
《Journal of Information Security》2012年第2期156-161,共6页Yonghong Chen Jiancong Chen 
In this paper, we present a novel technique based on a mixed Error Correcting Code(ECC)-the convolutional code and the repetition code to enhance the robustness of the embedded watermark. Before embedding, the binary ...

New Video Watermark Scheme Resistant to Super Strong Cropping Attacks
《Journal of Information Security》2012年第2期138-148,共11页Ming Tong Tao Chen Wei Zhang Linna Dong 
Firstly, the nonnegative matrix factorization with sparseness constraints on parts of the basis matrix (NMFSCPBM) method is proposed in this paper. Secondly, the encrypted watermark is embedded into the big coefficien...

On Secure Digital Image Watermarking Techniques被引量：2
《Journal of Information Security》2011年第4期169-184,共16页Manjit Thapa Sandeep Kumar Sood 
Digital watermarking is used to hide the information inside a signal, which can not be easily extracted by the third party. Its widely used application is copyright protection of digital information. It is different f...

Audio Watermarking Using Wavelet Transform and Genetic Algorithm for Realizing High Tolerance to MP3 Compression
《Journal of Information Security》2011年第3期99-112,共14页Shinichi Murata Yasunari Yoshitomi Hiroaki Ishii 
Recently, several digital watermarking techniques have been proposed for hiding data in the frequency domain of audio signals to protect the copyrights. However, little attention has been given to the optimal position...

Secure Spread-Spectrum Watermarking for Telemedicine Applications
《Journal of Information Security》2011年第2期91-98,共8页Basant Kumar Harsh Vikram Singh Surya Pal Singh Anand Mohan 
This paper presents a secure spread-spectrum watermarking algorithm for digital images in discrete wavelet transform (DWT) domain. The algorithm is applied for embedding watermarks like patient identification /source ...
