Abstract

In present times, identity protection is becoming increasingly jeopardized. Numerous ways of protecting one's personal, financial or medical information are therefore being utilized by individuals, businesses, and governments. When it comes to protecting patient information in medical images, we have developed an information hiding methodology that includes the RSA encryption algorithm and a Discrete Cosine Transform (DCT) based hiding technique. With this system, any medical image that will be electronically transferred (i.e. emailed, faxed, etc.) will have the patient's information hidden and embedded in the image outside of the Region of Interest (ROI). For example, an X-ray of a skull that is emailed will not have the patient information displayed during transmission, but will be readily available once it reaches its destination. This system is also unique in the fact that when a medical image is electronically delivered, the patient information and the picture are transferred in the same file, whereas now an image and the corresponding patient information are transmitted in two different files.
