I am interested in creating a program that graphically presents possible current BG based on insulin level, food eaten, exorcise contribution. A character/animal simulation avatar in real time would be very cool.

I'll be speaking on this topic at Blackhat this year.

Hi Jerome,
The AADE Expo (American Association of Diabetes Educators) is during the same weekend (Aug 3 -5) in the same city (Las Vegas). http://www.diabeteseducator.org/annualmeeting/2011/index.html

By the way, Pancreum will allow for users/developers to wirelessly (or via USB) retrieve their history (glucose levels, insulin delivery, carb intake, exercise, etc) to use it in a spreadsheet, graph, etc. We'll publish the method and API so that may be achieved. We hope that this approach will allow for multiple companies to develop and provide software solution packages in the mobile/PC/Mac that are capable to interface with the Pancreum products. The data will transmitted in an encrypted format, using a password chosen by the user.

Cheers,
Gil

Hi Jerome (Jay),

I see that you were able to hack your own diabetes management devices. Your work is all over the internet now:
"Insulin Pumps, Monitors Vulnerable to Hacking"

http://www.pharmpro.com/news/2011/08/newsletter-Insulin-Pumps-Monit...

That's why I always supported encryption, but never won those discussions at the companies I've previously worked for. At Pancreum I'm the decision maker, so as I mentioned on my previous post, all programming/reporting messages are encrypted.

I firmly believe in one exception: The data download/retrieval message and response will be open/public so multiple companies can create an array of graphing and analyzing software packages, for the patients' benefit. However, that message exchange will still be encrypted, but the encryption key will be a password selected by the patient.

By the way, on the article you didn't mention which pump and glucose meter/monitor you use, but you did here: "Dexcom, Minimed pump/GuardianRT and OneTouch Ultralink". I'm glad you will notify them about this potential vulnerability. That's important.

Good job at proving that point.

Cheers,
Gil

I've been searching for a group like this for years now and I'm grateful to have found it. I'm an active runner, sys admin, web developer, graphic designer, and of the past year app developer for Windows Phone 7. Since my diagnosis in 7th grade my father and I initially were controlling my diabetes regime from technology derived on a patent he owns with specific application in the oil industry and has the fantastic side effect of benefiting me as a new diabetic at the time.

For several years I averaged a 5.8-6.1 hA1c only only two injections a day (log/NPH) and at the mimimum four finger checks a day. This tech provided me a means of quite literally forecasting and predicting my dose for the upcoming day, as well as with a few test runs of the giant CGMs at the time demonstrating that blood sugar predictions 20 minutes out were possible.

I don't want to get people's hopes up, but I do want to ingrain myself in a culture that I've otherwise been searching for years now. With the recent Defcon announcement made by Radcliffe, I've been eager to construct a similar hack but closing the loop with said patent tech.

This article is a bit old, but if anyone is curious or would like to talk...well, let's do that! That's why I'm here!
http://www1.eere.energy.gov/industry/newsandevents/news_detail.html...

Additionally, I had my genome sequenced earlier this year to discover my chances of contracting diabetes were less than 1%

That's all for now, and I look forward to talking.

Hi Adam,

If there's already a patent, and you can demonstrate this "closed-loop" algorithm working, I suggest you approach one of the insulin pump makers in the market: MiniMed (MedtronicDiabetes), Animas (Johnson & Johnson), Disetronic (Roche Diabetes), Insulet, etc.

If it's a great algorithm they may be willing to work with you, license it, etc.

Cheers,
Gil

I've tried looking for connections via my endocrinologists (namely the reps from those companies that they work with), groups at Purdue Lafayette (where I got my degree), and thus far haven't found any willing to give me the time of day. But truthfully, I just don't know how to go about this process because calling the R&D department of Medtronic doesn't seem like something anyone can just do.

As stated earlier, the demonstration of a hacked pump presents all sorts of possibilities to me that I would be eager to test on myself in an attempt to marry the software with the hardware.

I see. Speak with Jay and see if he can help you. Cheers.

Gil, What's the timeline for Pancreum? Any foreseeable release date for the system described on the website? Sure looks good!

My son has Medtronic's medley of devices...I've wondered for some time why these devices haven't been made to communicate with a PDA/mobile device... Do you have any insight into that? Is it just a lag in the industry?

It's curious to me that a big company like Medtronic wouldn't be racing to do the same thing that Pancreum is doing...

Just saw your message. We're still in the engineering phase, and still negotiating with venture capital firms for more funding. So, still a few years away.
There are individual products controlled by a smartphone, but not the same smartphone controlling devices made by different companies. Those companies can't agree on that YET, unfortunately.
Medtronic IS racing to develop a wearable set of devices. I've hear they've spent more than US$ 100 million, but can't get it right like we did it at Insulet.
Cheers, Gil.

well.. I'm now on the road to hacking the DexCom G4.. I figured someone upstairs gave me the brains to hack at it, as to help my daughter.. so ordered some hardware to figure out the transmission protocol.

There are three goals to why I'm attempting this.
A) While she's in school, I think it would be an awesome feature for the parents to get a text message on the status of their children's glucose numbers. We're now onto our 3rd week, and see things on her CGM that we didn't know (ie stress from certain teachers causing her numbers to swing.. always the same pattern with the same teachers).

B) Repeating signals. Though the range of the G4 is awesome (my daughter is upstairs in her room doing homework, we are downstairs getting supper ready), we can see what's going on. Imagine repeaters (just like wifi), throughout the home or property, while the receiver stays inside.. total freedom)

C) Smartphone implementation. The CGM tech is cool, their windows management software is pretty cool.. the receiver is major "bleh". Either build a device with Android, or port the receiver as a smartphone app.. but then again, there's money to be made and it would be hard to charge hundreds for an app...so not holding my breath..

Seems like a no-brainer to have a pump or CGM or standard glucometer be bluetooth enabled for realtime transmission of data to a cloudbased database via iPhone/Android. Push notifications could keep parents in the loop.
