I just had another blog post published at work. This one is in in support of an eBook I have been working on for a while – with Mads Becker Jørgensen and Michael Bennet Cohn of course! Lets call me the editor of it. 

The ebook is about some things that are “hot topics” these days – the Internet of Things (IoT) and Blockchain technology. Blockchain is often just thought of as something for crypto currencies. But the intrinsic nature of its distributed database, makes it an excellent platform for an integrity assurance solution. The eBook talks about that in the context of IoT.

In a lot of ways Integrity is the poor child of the security trioka. The other two being Confidentiality – is my stuff secret. And Availability – can I get to it when I want. Integrity is about do I trust it. Has someone tampered with it. These are the differences between “is the bank’s internet service up” so you can get to your money (availability), “have account balances and transaction details remained private” (confidentiality), and has someone changed my balance to read €0 (integrity).

Pretty important when you get down to it. But read the book for more information.

The important thing though is that this is a real application of blockchain technology. And it is in use today. It’s not just hype.
