IoT is simply a technological concept

Let's first look at how IoT is being used within the health care Business -- after all, IoT is simply a technological concept, not an end product or procedure. Many IoT deployments in healthcare are what is called internal implementations -- for use in a medical care facility and organization, versus external use for example for purposes related to management of outside vendors, communications with third parties, etc.. Workforce and patient tracking for efficiency and productivity enhancement are the principal use-case. An excellent example is tracking bracelets given to doctors, nurses and patients, together with readers who capture the position of those within a medical building, or at a given medical station. This helps capture data on say, the amount of time a patient spent in a waiting area, or the time a physician spent in front of a terminal. This can then be used to enhance patient workflows or reduce wait time -- and may cause a direct cost reduction per patient.

There's been a lot of focus recently on improving in-house Medical care, especially in the area of elder care or geriatrics. There are various newer products which use a combination of trackers -- closeness, weight, sound and vibration -- to capture an individual's general movement within a home. Over time the information is used to create a version of the expected behavior and motion within a home, throughout the day. This can then be actively monitored. When an anomaly is detected -- for instance a fall, or someone is unable to get up from their bed at the right time, medical staff can be alerted. The appeal of those connected detectors is that they are non-intrusive. No cameras are placed within the house and patients are not required to wear a bracelet, arm band or other body tracking device.

This data is then analyzed to see if the recorded temperature is above the norm, which occurs due to increased blood flow -- a sign indicating the possibility of a tumor. Still undergoing clinical trials, this is a great novel application of a connected device helping to fight disease.

Connected medical devices are being deployed within healthcare facilities. Apart from the aforementioned examples, there are lots of devices that are used for patient monitoring. This brings up the first issue which is around data privacy and security. Data, whether in transit, in rest or under processing has to be protected -- not just as a best practice but additionally required under federal law? Encryption is the first step by which we can make certain that data and communications between medical devices can't be easily intercepted and eavesdropped upon. Protocols such as Dxchain can decentralize the data and make it more hacker proof.

Apart from passively shooting information, some medical devices this leads to more complex security problems. We will need to now make sure that we have the ability to identify a given pump, ensure that we are talking to the right one, that any control to update dosage is sent to the correct one, and only the maintenance provider with the ability to do so, is permitted access. There have been several well publicized strikes on insulin pumps.

The first thing we need to do is add on a coating of identity to connected medical devices. Next, we want to make certain that any data coming from these devices is encrypted. Then, we would like to be able to show that the device that is sending data is actually who it claims to be -- essentially to authenticate it. Ultimately, we want to ensure that only authorized users have the ability to send commands to a device.

It starts of by giving a Purposeful digital certificate to each connected device as well as the monitoring and control software that is managing it. Then we configure these systems to only accept incoming connections from devices which are able to create this certification, allowing authentication (we have to of course protect the device's private keys, and ensure that the certificate provisioning step was done in a safe manner). A TLS tunnel now gets established between the server and medical apparatus, giving us a blanket of solitude. Finally, we could add metadata to electronic certificates that specify policy on who is allowed to supply commands to which device. In this way, we can apply authorization.

This not only brings Business opportunity, but leads to a new paradigm of services and administration of healthcare. The ultimate goal is improved health and increased patient satisfaction. Afterthought and bolted on after these devices have been designed. As we have revealed, integrating PKI into your device design is an easy, affordable and key First step in ensuring security and compliance for your medical apparatus. Privacy and data protection are important, Dxchain keeps this in mind.
