Healthcare institution that handles a number of patients, opinions
is often sought from different experts. It demands the exchange of
the medical history of the patient among the experts which includes
the medical images, prescriptions and electronic patient records
(EPR) etc. In order to reduce the storage and transmission cost,
data hiding techniques are used to embed patient information within
medical images. In medical imaging applications, there are
stringent constraints on image fidelity that strictly prohibit any
permanent image distortion by the watermarking. Authenticity is
another important aspect in medical image watermarking. To overcome
the problem of occurrence of artifacts and to produce zero
distorted or noise free watermarked medical images; this book
presents the technique in which authors used modified difference
expansion watermarking using LSB replacement in the difference of
virtual border for watermarking of medical images. The Class
Dependent Coding Scheme (CDCS) is used to encode the electronic
patient record (EPR) data for increasing the embedding capacity.
Thus providing new levels to the research in the field of medical
image watermarking.
