Confidential patient information could be camouflaged in readings from medical sensors and sent to hospitals without falling into the wrong hands
Elderly patients or those with chronic diseases are increasingly able to monitor their condition from home or other convenient locations because their vital signs and test results can be sent over the Internet to their physicians. But as this becomes standard practice, patient confidentiality is an increasing concern. At RMIT University, in Melbourne, Australia, scientists are working on a way to hide a patient’s private data in plain sight.
The technique uses stegnanography: a practice of embedding informaton inside a larger block of data secretly, without noticebaly affecting the size or character of the larger data.
