The discussion on manufacturer responsibility is key. What incentives beyond regulatory compliance can encourage manufacturers to prioritize robust security from the outset, given potential cost implications?
That’s a great point! Thinking beyond compliance, perhaps insurance premium reductions or preferred vendor status with large healthcare systems could incentivize manufacturers to invest in robust security measures from the start. Building trust through demonstrable security could be a significant market differentiator.

AI and blockchain, huh? Sounds like a recipe for either groundbreaking security or a spectacular Skynet-esque failure. I’m curious, what happens when the AI designed to protect IoMT devices *is* the one hacked? Asking for a friend… who is a hypochondriac.
That’s a fantastic question! The potential for AI to be compromised is definitely a concern. Redundancy and layered security are key – think of it as a defense-in-depth approach where multiple AI systems, each with different architectures and oversight mechanisms, are used to protect the IoMT devices. It’s a challenge, but a fascinating one!

Standardized communication protocols, eh? So, are we talking one universal language for IoMT, or just a really good Babel Fish implant for the doctors? Asking for a friend who… well, you get it.
That’s a fun analogy! While a Babel Fish implant sounds convenient, a true universal language for IoMT would be more about standardized data formats and secure transmission protocols than spoken language. Think more like computers agreeing on how to talk to each other, regardless of the manufacturer. It’s less sci-fi, more secure interoperability. What are your thoughts?
