New Watermarking Technique Using Data Matrix and Encryption Keys

New Watermarking Technique Using Data Matrix and Encryption Keys

Meaningful logos or random sequences have been used in the current digital watermarking techniques of 2D bar code. The meaningful logos can not only be created by copyright holders based on their unique information, but are also very effective when representing their copyrights. The random sequences enhance the security of the watermark for verifying one's copyrights against intentional or unin...

A new Watermarking Technique for Medical Image using Hierarchical Encryption

In recent years, characterized by the innovation of technology and the digital revolution, the field of media has become important. The transfer and exchange of multimedia data and duplication have become major concerns of researchers. Consequently, protecting copyrights and ensuring service safety is needed. Cryptography has a specific role, is to protect secret files against unauthorized acce...

Joint Encryption and Watermarking Technique Using Block Cipher and Wavelet

This paper proposes a joint encryption and watermarking technique based on random block permutation and DWT with the motivation to enhance the security of the multimedia content. The original image is sectioned into the blocks and shuffle the blocks using random permutation, In this technique copyright information is concealed into an encrypted image. Based on the results, permutation of blocks...

A New Fast Data Encryption Algorithm (FDE)

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...
