citadrianne writes: Jay Radcliffe is a security researcher with diabetes. In 2011, he gave a talk at Black Hat, showing how his personal insulin pump could be hacked—with potentially deadly consequences. As a result of his 2011 presentation, he worked with the Department of Homeland Security and the Food and Drug Administration to address security vulnerabilities in insulin pumps. "The specific technical details of that research have never been published in order to protect patients using those devices," he wrote in his testimony to the Librarian of Congress and the U.S. Copyright Office. Every three years, the Librarian of Congress puts a whole bunch of people through a twisted bureaucratic process called DMCA (Digital Millennium Copyright Act) rulemaking. Technically speaking, DMCA rulemaking doesn't make things illegal or legal per se, but many people—like Jay Radcliffe—look to the rulemaking for a green light to do their work.
