Abstract
Medical information is maintained in a digital format, like scanned images
along with patient information. In the mobile health care system, digitized medical
information is transmitted to remote specialists for diagnosis purposes. The remote
specialists verify the patient medical information using mobile or other devices and
suggest the treatment. During medical data transmission, through unsecured media,
there is a chance to modify the medical data by the attacker. It leads to the wrong
diagnosis and affects the patient's entire life. So there is a need for secure medical data
transmission in mobile healthcare to protect medical information from unauthorized
users or intruders. The medical image watermarking technique is required to protect
medical information in mobile healthcare. To withstand various medical image
watermarking attacks, this chapter discusses two different types of robust medical
image watermarking techniques in mobile healthcare. First, an intelligent-based
medical image watermarking technique is discussed to protect the medical data in a
secured manner during the electronic patient information embedding part. After
embedding the patient information in the medical image, the generated watermarked
medical image looks like an original medical image. So the attacker knows the visual
existence of the medical data during its transmission. To avoid this, the second
technique, i.e., the visual medical image encryption technique, is discussed. The mobile
healthcare system uses the intelligent medical image watermarking technique and
visual medical image encryption for the secure transmission of medical information.
