A team led by presenter Tokuo Umeda, PhD, has developed a technique that makes use of digital watermarking technology to hide electronic patient record data, the hash values of the regions of interest, the name of the institute, and patient support system data in the regions of noninterest in a chest CT series.
They also employ steganography, the practice of hiding information within another medium in a manner that can't be suspected by a third party. For example, they stored a series of body CT images in a folder, which was then embedded in a cover picture of a landscape photograph and then sent to other medical institutions.
The system ensures image copyright and protects the privacy and security of electronic patient records, according to Umeda. In addition, both technologies would be suitable for all digital images, not just CT, he said.
