Watermarking of digital mammograms without interfering with automatic detection of microcalcifications

In this paper we show that it is possible to watermark digital mammograms with patient information without interfering significantly with an existing method for automatic detection of microcalcifications. The paper discuss which type of information that should be embedded in digital medical data, i.e. what the digital watermark should consists of. Robustness requirements relevant for this watermarking application are discussed and taken into account.
