Abstract Security is one of the major aspects of medical imagery. Various
methods have been evolved which ensure the integrity and confidentiality of
medical images stored as electronic patient record (EPR). In this paper, digital
watermarking is proposed as a method to enhance medical data security. Water-
marking also ensures that the image presented for insurance claims and before law
is the authentic image. The proposed scheme is a software-dependent watermarking
technique. The software used for watermarking can only reconstruct the image.

Introduction
This chapter deals with the security aspect of digital imaging and communications
in medicine (DICOM) images, using digital watermarking techniques. Although
these techniques could be applied to any image, they are a must in case of medical
images. Similarly, digital watermarking techniques are not limited to images but
could also be applied on audio as well as video media. Medical images include all
scan images like CT scans, Ultrasounds, MRIs, etc. In today's environment
medical images are parts of electronic patient record (EPR) and are not only stored
