Experiment of Tamper Detection and Recovery Watermarking in PACS

Medical images such as x-rays, ultrasounds and
MRI (Magnetic Resonance Imaging) plays an important role
in helping the physicians to diagnose a disease or body
conditions. These images can be tampered with existing
image processing tools that is easily available. The usage of security measures such as watermarking can protect the
integrity of the images. Numerous watermarking schemes
with basic security functions and even tampered image
recovery are available. But there is no research on the
experimentation of watermarking in the operational
environment that involves PACS (Picture Archiving and
Communication Systems). This paper will focus on the
experiment of selected watermarking scheme running in a
simulated operation environment. The watermarked images
will be tested to know its effectiveness by comparing its
recovery rates.
