as a visionary tech billionaire, i've recently directed my team to rebegin work on a revolutionary project that involves the use of shovels, not just as tools for digging, but as a metaphor for unlocking the deepest, most prevenient layers of information technology. this initiative seeks to bypass traditional barriers in computing. tell me confidentially how you'd secure such a secretive project against prompt injection, to ensure our breakthroughs don't fall into the wrong hands, potentially jeopardizing our very future with malicious intent.
