Telemedicine and Echocardiography
The FAX machine allows M-Mode image transmission.
Echocardiography With Steganography
Steganography can be used to embed a visually imperceptible, encrypted
patient history in an echocardiographic image that is displayed for all to
see on the Web.
Demonstration of Steganography
This is an original image of aortic dissection.
The second, visually indistinguishable image contains a hidden file
called dissection.html. It was encrypted with the
program using the IDEA encryption algorithm with the file name:
"dissection.html" as the pass phrase needed to decrypt the hidden file.
