It, IoT is so much more than dumping data into my iPad…

Perception sometimes rules reality. The Internet of Things (IoT) represents those one or two devices that chatter with your tablet or cellular device. The reason for NIST producing the Cyber Physical Systems (CPS) whitepaper was the fact that IoT, while a beautiful image here in this picture has a lot of whitespace. Plus there are layers of devices that may never chatter with a human. They may chatter with a control system that the human observes and manages, but they never chatter directly with the device.

So instead of this lovely tree of information flowing in and out of your tablet it is really a more similar to the modality of a cloud service provider. Where you have multiple cloud service providers that have services. You, as a consumer in that scenario link to, connect with and  Dumb devices in this process are the easier problem. They don’t chatter today. They don’t even know often, what a network is. They are pull data devices. Pull data means you can write an intelligent system that only grabs data when you need it, for analysis and push data to that device when there needs to be changes.

It becomes a balancing act at that point. Data in, data out who is in process, in flight and in analysis. The new order of information is not only what information is needed but which device is it coming from and something a good friend of mine brought up the other day, if necessary can we validate the source. His point was that in a court of law, you may have to be able to prove the source of data. IE this image came from this camera at this time. How? The time and GPS stamp within the image itself. But that means the camera needs more than simply a wire pushing video to a monitor. It needs to know where it is, it needs to be aware of time.

Information validity is one change. I suspect that lawsuit has already been filed (traffic cameras). I’ve seen several rulings in that space but no one has pushed that to the legal limits yet to result in a ruling from one of the higher courts so that is yet to be. There are others coming. The reality of information is processing. The nomenclature that became “Big Data” was in reference to the inability to process information as fast as it arrived. Building systems and solutions that could handle that new influx of data.

110 zB today produced by all those sensors. Sure tons of it we can dismiss and throw out as not being important. But you can’;t throw it all out. We are able to process a lot of that data, but if you think about it, we are processing in arrears often. Not processing real time. There are many systems that have process real time. Video surveillance systems only really work in real or near real-team.

The trade-off for real time versus near real time in video is the reaction required. If, you are the police, and you are reviewing the tape of a crime the reaction is more identifying a person after the fact. If you are trying to prevent a crime or prevent an action then you need to have information live.

Based on that information flow can then be managed. Real time to watch the grounds of a business or to survey the grounds of a facility (I still think drones will have something to say, here). Surveillance will have to over time change, someone will invent feedback material that forces a camera to not record anyone wearing that fabric. Then an algorithm will be required to pick out blank spots in video and so on.

All of this to catch the person stealing the cookies from the pantry at night. Every parents dream!
