Seminar: Paper Watermark Location and Identification

Friday July 3rd at 16:30

Note: STB 9 (Stewart House), Senate House, Malet Street, London, WC1E 7HU

*Roger Boyle & Kia Ng (Leeds)*
*Extracting the Hidden: Paper Watermark Location and Identification*


Watermark studies go back many years, but the advent of large digital repositories and advances in imaging present new opportunities. We present two attacks. Both use a back-lighting approach that delivers good quality, digitally-native images. We exhibit work on a wide range of images, and have uncovered hitherto unseen results.

The seminar will be followed by wine and refreshments.

For more information please contact,,, or, or see the seminar website at, where a longer abstract is available, and the audio and slides will be posted shortly after the event.
