%X Fragile watermarking has been proposed as a means
of adding additional security or functionality to biometric systems,
particularly for authentication and tamper detection. In this paper
we describe an experimental study on the effect of watermarking
iris images with a particular class of fragile algorithm, reversible
algorithms, and the ability to correctly perform iris recognition.
We investigate two scenarios, matching watermarked images
to unmodified images, and matching watermarked images to
watermarked images. We show that different watermarking schemes
give very different results for a given capacity, highlighting the
importance ofinvestigation. At high embedding rates most algorithms
cause significant reduction in recognition performance. However,
in many cases, for low embedding rates, recognition accuracy is
improved by the watermarking process.
