Digital media has revolutionized the way still images and image sequences are stored, manipulated and transmitted, giving rise to a wide range of new applications such as digital television, digital videodisc, digital image databases and electronic publishing. These new applications are expected to have an important impact on the electronics and entertainment industry.

With the advent of new image and video media, issues of copyright protection have become more important since efficient distribution, reproduction and manipulation have led to wide proliferation of digital media. The popularity of the World Wide Web has clearly demonstrated the commercial potential of the digital multimedia market and consumers are investing heavily in digital audio, image and video recorders and players. Unfortunately however, digital networks and multimedia also offer virtually unprecedented opportunities to pirate copyrighted material. Digital storage and transmission make it trivial to quickly and inexpensively construct exact copies. For this reason creators and distributors of digital data are hesitant to provide access to their intellectual property. Creators of such digital data are actively seeking reliable solutions to the problems associated with copyright protection of multimedia data.

The future development of networked multimedia systems is conditioned by the development of efficient methods to protect data owners against unauthorized copying and redistribution of digital material. A method of copyright protection is the addition of a "watermark".

Digital watermarking has been proposed as a means to identify the owner or distributor of digital data. Watermarking is used for the authenticity of the media and by encoding hidden copyright information into digital data by making small modifications to the data samples. Unlike encryption, watermarking does not restrict access to data. Once encrypted data is decrypted, the media in no longer protected.

Key elements in the development of a digital watermark are its invisibility, security, robustness, complexity, compressed domain processing, constant bit-rate and interoperability.

We at MEP technologies interface highly efficient algorithms that contain these key elements. Through our dedication to our customers to provide unsurpassed security, our software always leads the industry standard in digital watermarking. Let us at MEP help you protect what's yours.
