Genome theft is already a possibility, and that problem looks like it’s only going to grow.
Personal genetic information is currently a subject of intense scientific interest, because one of the major goals of today’s biomedical science is to figure out how we can use information in your DNA to customize your medical care. Your individual genome has a strong influence on how your body responds to efforts to prevent and treat disease, and in the coming years, doctors will begin to routinely use genetic information in patient care. As the practice of genetic medicine becomes increasingly common, more and more of us will use genetic testing services, which means that more and more of us will have our genetic data stored in some sort of database. This will put some very personal information at risk, because, as Visa will tell you, databases can be hacked.
