Digital Watermarking Alliance

Last updated

The Digital Watermarking Alliance is a group of like-minded companies that share a common interest in furthering the adoption of digital watermarking. The mission of the Digital Watermarking Alliance is:

Digital watermarking

A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video 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; 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.

A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light, caused by thickness or density variations in the paper. Watermarks have been used on postage stamps, currency, and other government documents to discourage counterfeiting. There are two main ways of producing watermarks in paper; the dandy roll process, and the more complex cylinder mould process.

A watermark stored in a data file refers to a method for ensuring data integrity which combines aspects of data hashing and digital watermarking. Both are useful for tamper detection, though each has its own advantages and disadvantages.

The copy attack is an attack on certain digital watermarking systems proposed by M. Kutter, S. Voloshynovskiy, and A. Herrige in a paper presented in January, 2000 at the Photonics West SPIE convention.

Secure Digital Music Initiative (SDMI) was a forum formed in late 1998, composed of more than 200 IT, consumer electronics, security technology, ISP and recording industry companies, as well as authors, composers and publishing rightsholders, ostensibly with the purpose of developing technology and rights management systems specifications that will protect once developed and installed, the playing, storing, distributing and performing of digital music.

The International Recording Media Association (IRMA), previously known as the International Tape Association (ITA), was an international trade association dealing with every facet of recording, media and related industries. Their membership includes raw material providers, manufacturers, replicators, duplicators, packagers, copyright holders, and others.

The Broadcast Protection Discussion Group (BPDG) is a working group of content providers, television broadcasters, consumer electronics manufacturers, information technology companies, interested individuals and consumer activists. The group was formed specifically for the purpose of evaluating the suitability of the broadcast flag for preventing unauthorized redistribution and to determine whether there was substantial support for the broadcast flag. The group completed its mission with the release of the BPDG Report.

Video fingerprinting is a technique in which software identifies, extracts, and then summarizes characteristic components of a video recording, enabling that video to be uniquely identified by its resultant "fingerprint". This technology has proven to be effective at identifying and comparing digital video data.

The analog hole is a perceived fundamental and inevitable vulnerability in copy protection schemes for noninteractive works in digital formats which can be exploited to duplicate copy-protected works that are ultimately reproduced using analog means. Once digital information is converted to a human-perceptible (analog) form, it is a relatively simple matter to digitally recapture that analog reproduction in an unrestricted form, thereby fundamentally circumventing any and all restrictions placed on copyrighted digitally distributed work. Media publishers who use digital rights management (DRM), to restrict how a work can be used, perceive the necessity to make it visible or audible as a "hole" in the control that DRM otherwise affords them.

Digital rights management (DRM) is a set of access control technologies for restricting the use of proprietary hardware and copyrighted works. DRM technologies try to control the use, modification, and distribution of copyrighted works, as well as systems within devices that enforce these policies.

Copyright infringement Intellectual property violation

Copyright infringement is the use of works protected by copyright law without permission, infringing certain exclusive rights granted to the copyright holder, such as the right to reproduce, distribute, display or perform the protected work, or to make derivative works. The copyright holder is typically the work's creator, or a publisher or other business to whom copyright has been assigned. Copyright holders routinely invoke legal and technological measures to prevent and penalize copyright infringement.

Civolution is a provider of technology and services for identifying, managing and monetizing audio and video media content. The company offers a portfolio of proprietary and patented digital watermarking and digital audio and video fingerprinting technology solutions for media protection: forensic tracking of media assets in pre-release, digital cinema, Pay Television and online; media intelligence: audience measurement, broadcast monitoring, internet and radio tracking; media interaction: automatic content recognition and triggering for second screen and connected television.

Automatic content recognition (ACR) is an identification technology to recognize content played on a media device or present in a media file.
