A Hybrid technique of Video Watermarking in Wavelet domain and Scan based Encryption Method

چکیده
Security of digital products (audio, video, image, and text) on the internet is very essential these days, for these digital watermarking techniques are used. Digital watermarking is the process of embedding data into digital multimedia content. This is used to validate the reliability of the content or to recognize the identity of the digital content's owner. Sophisticated watermarking techniques have recently been developed, and they can be used to embed in printed text, graphics, or images as well as in digital images, graphics, audio, or video. This present survey is on DWT (Discrete Wavelet Transform) technique used in watermark. DWT transform more computationally efficient than other transform methods, because of its outstanding localization properties which offer the compatibility with the Human Visual System (HVS).

The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...

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...

متن کاملAn Optimized Dwt Based Approach in Video Watermarking with Multiple Watermarks Using Oppositional Krill Herd Algorithm
In video watermarking applications, there is a need to extract the watermark without using the original data because of the huge storage of the cover data. In this paper, we have intended to present an efficient multiple video watermarking using optimized three levels DWT. Basically, the system consists of three modules such as (i) selecting optimal wavelet coefficients using Oppositional Krill...
