3. A fingerprinted image can be identified in both printed and digital form and this allows an audit trail so that image providers can monitor and track the use of their material The highly robust SureSign fingerprint is part of the image file data itself but does not increase the amount of raw image data and it is impractical to remove the fingerprint as this renders the image unusable SureSign fingerprints are designed to be detectable even after the file has been cropped re sized compressed or copied and even when the image is re used as part of a composite picture Furthermore the fingerprints are visually imperceptible and will not degrade high quality images including those intended for pre press use SureSign fingerprint detectors are widely distributed and available free from the Signum Web site and also via third parties This means that everybody can easily identify fingerprinted images held or used by them SureSign fingerprinting tools are very affordable with solutions designed to match the cost and productivity needs of both individual and corporate image providers The technology can be used on its own or in combination with other protective devices such as encryption or visible watermarking Signum Technologies is committed to providing new and innovative copyright protection and communication solutions for creators providers and consumers of digital content 1 Introduction http www signumtech com Page 2 1 2 The
