Facilitating Watermark Insertion by Preprocessing Media

There are several watermarking applications that require the deployment of a very large number of watermark embedders. These applications often have severe budgetary constraints that limit the computation reso...

Linear and Nonlinear Oblivious Data Hiding

The majority of the existing data hiding schemes are based on the direct-sequence (DS) modulation where a low-power random sequence is embedded into the original cover signal to represent hidden information. I...

Improved Bit Rate Control for Real-Time MPEG Watermarking

The alteration of compressed video bitstream due to embedding of digital watermark tends to produce unpredictable video bit rate variations which may in turn lead to video playback buffer overflow/underflow or...

Watermarking Algorithms for 3D NURBS Graphic Data

Two watermarking algorithms for 3D nonuniform rational B-spline (NURBS) graphic data are proposed: one is appropriate for the steganography, and the other for watermarking. Instead of directly embedding data i...

Secure Multimedia Authoring with Dishonest Collaborators

Many systems have been proposed for protecting the intellectual property of multimedia authors and owners from the public at large, who have access to the multimedia only after it is published. In this paper, ...

A Secure and Robust Object-Based Video Authentication System

An object-based video authentication system, which combines watermarking, error correction coding (ECC), and digital signature techniques, is presented for protecting the authenticity between video objects and...

RST-Resilient Video Watermarking Using Scene-Based Feature Extraction

Watermarking for video sequences should consider additional attacks, such as frame averaging, frame-rate change, frame shuffling or collusion attacks, as well as those of still images. Also, since video is a s...

MPEG-4 IPMP Extension for Interoperable Protection of Multimedia Content

To ensure secure content delivery, the Motion Picture Experts Group (MPEG) has dedicated significant effort to the digital rights management (DRM) issues. MPEG is now moving from defining only hooks to proprie...

Video Waterscrambling: Towards a Video Protection Scheme Based on the Disturbance of Motion Vectors

With the popularity of high-bandwidth modems and peer-to-peer networks, the contents of videos must be highly protected from piracy. Traditionally, the models utilized to protect this kind of content are scram...

Image Content Authentication Using Pinned Sine Transform

Digital image content authentication addresses the problem of detecting any illegitimate modification on the content of images. To cope with this problem, a novel semifragile watermarking scheme using the pinned ...
