A Review Paper on Forensic Watermarking
نویسندگان
چکیده
Watermark is a pattern or image coverted in a paper to discourage counterfeiting of the document. Encoding such a pattern or signal into digital data like image, music, video etc is called Digital Watermark also known as Forensic watermarking. The embedding of the watermark information takes place by manipulating the content of the digital data. The hiding process should be such that the modifications of the media are imperceptible. In this paper we describe the process of Digital Watermarking, the various classifications related to it, the possible distortions and attacks, Bench mark and the types of Bench Mark, the Applications and the recent advancements in this area.

Forensic Tracking Watermarking against In-theater Piracy
Many illegal copies of digital movies by camcorder capture are found on the Internet or on the black market before their official release. Due to the angle of the camcorder relative to the screen, the copied movies are captured with perspective distortion. In this paper, we present a watermarking scheme for tracking the pirate using local auto-correlation function (LACF) to estimate geometric d...
متن کاملVideo Forensic Marking Algorithm using Peak Position Modulation
Forensic marking, a type of watermarking, is an efficient means of detecting copyright violation and tracing unauthorized access to digital content. In this paper, a new video forensic marking algorithm is proposed which uses peak position modulation (PPM) and can embed sufficient information to trace an illegal distributor. PPM uses the positions of correlation peaks, which are modulated by us...

This paper supports techniques for checking the legal status of virtual goods. Forensic DRM means the usage of these techniques for legal procedures. Especially techniques like digital watermarking and fingerprinting pursue the approach of marking digital items before the delivery to the customers, in order to identify illegal copies of these items later. The described techniques can be used to...
متن کاملA 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 ...
