| Popis: | Functional magnetic resonance imaging (fMRI) provides an effective and noninvasive tool for researchers to understand cerebral functions and correlate them with brain activities. In addition, with the ever-increasing diffusion of the Internet, such images may be exchanged in several ways, allowing new research and medical services. On the other hand, ensuring the security of exchanged fMRI data becomes a main concern due to their special characteristics arising from strict ethics and legislative and diagnostic implications. Again, the risks increase when dealing with open environments like the Internet. For this reason, security mechanisms that ensure protection of such data are strongly required. However, we remark that the mechanisms commonly employed for data protection are doomed to fail when dealing with imaging data. In this article, we propose a novel watermarking scheme explicitly addressed for this type of imaging. Such a scheme can be used for several purposes, particularly to ensure authenticity and integrity. Moreover, we show how to integrate our scheme within commercial off-the-shelf fMRI system. Finally, the validity and the efficiency of our scheme has been assessed through testing. |
