digital watermarking

His work in this area has included techniques for text-based digital watermarking.

Digital watermarking may be used for a wide range of applications, such as:

The isolation lemma has been proposed as the basis of a scheme for digital watermarking.

Examples include work on wireless communications, multi-antenna systems, optical transmission, and digital watermarking.

One application of digital watermarking is source tracking.

A story describes the latest Web-encryption device: digital watermarking.

In fragile digital watermarking, the extraction algorithm should fail if any change is made to the signal.

Digital watermarking is distinctly different from data hashing.

People doing "informed digital watermarking" use dirty paper codes, using this analogy:

"to create awareness and promote the value of digital watermarking to content owners, industry, policy makers, and consumers."

Recently, DPC has also been used for "informed digital watermarking".

For the perceptibility of digital watermarks, see Digital watermarking.

Since a digital copy of data is the same as the original, digital watermarking is a passive protection tool.

Digital Watermarking & Data Hiding research papers at forensics.

She is instead opting for digital watermarking that links the identity of the purchaser to the copy of the e-book.

A disadvantage of digital watermarking is that a subscriber cannot significantly alter some files without sacrificing the quality or utility of the data.

Both steganography and digital watermarking employ steganographic techniques to embed data covertly in noisy signals.

But whereas steganography aims for imperceptibility to human senses, digital watermarking tries to control the robustness as top priority.

Civolution offers a suite of product and solutions using proprietary and patented digital watermarking and fingerprinting technologies.

The key component of the Secure Digital technology is digital watermarking, embedding an electronic identification in CD's.

A watermark stored in a data file refers to a method for ensuring data integrity which combines aspects of data hashing and digital watermarking.

Video fingerprinting should not be confused with digital watermarking which relies on inserting identifying features into the content itself, and therefore changing the nature of the content.

The latest advancements in both digital watermarking and fingerprinting technologies have allowed new applications and business models for synchronization, triggering and monetization of content.

Steganography can be used for digital watermarking, where a message (being simply an identifier) is hidden in an image so that its source can be tracked or verified.

Fingerprinting and digital watermarking for relational databases emerged as candidate solutions to provide copyright protection, tamper detection, traitor tracing, and maintaining integrity of relational data.
