A Survey on Image Watermarking Techniques
نویسندگان
چکیده
Together with an explosive growth in the use of internet and high speed computer networks; the use of digitally formatted data has increased many folds i.e. the data can be easily plagiarized, modified or deleted without proper authentication and authorization. This has led to a need for effective copyright protection tools. Digital Watermarking promises to address these issues. This paper gives a survey of Digital Image Watermarking which helps general readers have an overview of digital image watermarking including the definition, system requirements and process involved. In addition, the future research directions of digital image watermarking are discussed. Keywords-Image Watermarking, Discrete Cosine Transform, Discrete Wavelet Transform.

A Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

متن کاملA Survey on Digital Watermarking Techniques
A digital watermark is a kind of marker covertly embedded in a noise tolerant signal such as audio or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal. Embedding a digital signal (audio, video or image) with information which cannot be removed easily is called digital watermark...
متن کاملPerformance Comparison of Digital Image Watermarking Techniques: A Survey
Digital watermarking is the processing of combined information into a digital signal. A watermark is a secondary image, which is overlaid on the host image, and provides a means of protecting the image. In order to provide high quality watermarked image, the watermarked image should be imperceptible. This paper presents different techniques of digital image watermarking based on spatial & frequ...
متن کاملProposing 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...
