Digimarc Announces ImageBridge Software  Development Kit For Linux

New Digimarc ImageBridge SDK enables Linux applications to
embed, detect and read digital watermarks

Tualatin, Ore. 

? April 10, 2001 ? Digimarc Corp. (NASDAQ: DMRC) announced today
the introduction of the Digimarc ImageBridge software development kit (SDK)
Linux. The ImageBridge SDK for Linux expands Digimarc's offerings for the
community and is available immediately.  The addition of the ImageBridge SDK
Linux is an important step in the extension of Digimarc technology, one that
allows greater numbers of customers to incorporate digital watermarking into
their own software applications and creative processes.

The ImageBridge SDK for Linux provides three basic functions: Embed watermark,
Detect watermark and Read watermark.  Embed watermark embeds a Digimarc
watermark in an image.  Detect watermark offers a quick means of determining
a watermark is present in an image, typically in less than one second
of image size.  Read watermark retrieves the contents of a Digimarc watermark
found in an image and links viewers to image owner information across the Web.
Digital watermarks embedded using the SDK are compatible with the full range
Digimarc ImageBridge watermarking and MarcSpider image tracking services.

Corporations and software vendors with imaging applications developed on Linux
will now have the ability to integrate Digimarc digital watermarking
into their own software programs. "By providing the ImageBridge SDK for Linux,
we are supporting the fast growing Linux development community and continuing
our strategy of providing ImageBridge watermarking across all major computing
platforms and application spaces," said Larry Trevarthen, director of product
marketing at Digimarc.  "We are excited to offer this additional support for
companies as they seek to communicate ownership and protect their images

Implementation of the ImageBridge SDK for Linux makes it possible to create
custom applications to integrate with the Digimarc ImageBridge watermarking
products, which provide comprehensive capabilities for copyright
online image tracking and image commerce.
