What is Watermarking

1.

Inserting or embedding a kind of digital information inside other kinds or similar kinds of digital information. Learn more in: A Novel Blind Wavelet Base Watermarking of ECG Signals on Medical Images Using EZW Algorithm

2.

The process of hiding digital information in a carrier signal; the hidden information should, but does not need to contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Learn more in: Data Hiding Schemes Based on Singular Value Decomposition

3.

The watermarking algorithms are applying watermarks (invisible information in bitstreams) to digital images. Learn more in: Digital Rights Management in Peer To Peer Cultural Networks

4.

Watermarking is a well-known technique used to hide data or information imperceptibly within image, audio, or video so that valuable contents can be protected. Learn more in: Multiple Description Coding with Application in Multimedia Watermarking

5.

The process of embedding information/data of any type into another digital signal(audio/video/text/image), to verify its authenticity or owner identification. It is similar to paper/currency notes bearing visible watermarks for visual authentication and identification. A signal may carry several different watermarks at the same time. It may be visible (where watermark is visible in the picture/video) or invisible (not visible to naked eye but can be extracted digitally). Learn more in: Watermarking of Data Using Biometrics

6.

The embedding of a mark within a media object. The mark can later on be retrieved from the media. Learn more in: Scalable Distribution of Watermarked Media

7.

It is the process of embedding a logo or digital signature in a media (image, video and other) for Copyright protection. Learn more in: Digital Video Watermarking Using Diverse Watermarking Schemes

8.

Imperceptible embedding of data into digital hosts (images, audio, video, text, etc.). Learn more in: Reversible Watermarking

9.

Process of inserting a hidden code or message into a digital or analog object. As opposed to steganography, it has the additional notion of robustness against attacks. As the name suggests, the additional data (the watermark) is added in order to protect the digital document from copyright infringements. Even if the existence of the hidden information is known, it has to be hard for an attacker to destroy the embedded watermark without destroying the data itself.

10.

It is a method which is used for checking signal’s authentication and integrity. It achieves its goal by covering the digital information behind the carrier signal. Learn more in: Reviewing the Security Features in Contemporary Security Policies and Models for Multiple Platforms

11.

It is a pattern of bits inserted into a digital image, audio or video file that identifies the file's copyright information (author, rights, etc.). Learn more in: Authentication and Error Resilience in Images Transmitted through Open Environment

12.

It is a data hiding technique which primary motive is to authenticate. Watermarking can be visible or invisible. Here the cover image is also important along with the embedded message. Robustness is the main criteria for selection of embedding algorithm. Learn more in: Steganography Using Biometrics
