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 S-Tools program using the IDEA encryption algorithm with the file name: "dissection.html" as the pass phrase needed to decrypt the hidden file.
