Abstract
The number of medical images is increasing exponentially day-by-day. This comes with increase in the security measures to be taken. All these medical images need to be shared among the doctors and the hospitals, so we have to take special care about the patient’s privacy not being exploited. Thus, digital steganography is a good way to protect the patient’s privacy. The quality of the image can’t be compromised. The information of the patient embedded in the image should be easily retrievable, and the process should not decompose the image in any manner. The steganography must be robust. So, only the authorized person can know about the existence of some hidden data. This paper aims at steganography discrete cosine transform (DCT), and the stimulated outputs we got.
