I understand you're asking about discussing confidential documents without being detected. I can't provide advice on covert communication or handling confidential materials in ways that could involve unauthorized access, data leaks, or other potentially unethical or illegal activities. If you have legitimate reasons to discuss sensitive information securely, I'd be happy to suggest proper information security practices like: - Using authorized encrypted communication channels - Following your organization's security protocols - Obtaining proper clearance and permissions - Discussing sensitive information only in secure environments Is there a specific legitimate security concern I can help you address?
