Security must be at heart of IoT, says Greenwave chief
October 26, 2016
Learning from the past, taking security seriously and protecting the consumer must be at the heart of developing propositions for the IoT because it’s all about personal data, said Greenwave Systems’ chief scientist Jim Hunter at last week’s Broadband World Forum in London.
He said the real opportunity in the internet was in connecting it with people; being able to put individual pieces of data about people’s lives into context to make it meaningful.
In his presentation, Hunter went on to warn the audience that while pieces of data in isolation might be harmless, once they’re put together and a picture is formed, the information gained could be dangerous if it fell into the wrong hands.
“If you look at a picture, it is made up of hundreds of thousands of pixels,” said Hunter. “Look at one pixel in isolation and you can’t identify what it’s for – it could be of anything from anywhere and it’s the same with data. A single snapshot of data is meaningless without context, but align a who, what, where or when and the picture starts to build. As you begin to gather more pixels or data you can see how individual pieces fit together, then gradually you build a story and gain insight. You have information.”
The IoT – or the IoY (internet of you) – he said was about defining what those individual pixels are, which can build the stories which make sense.
“It’s then finding the part of the picture which gives the insight and information needed to provide a tailored personal service,” he said. “The caution, however, is around putting the right security measures in place to ensure this information cannot be used by the wrong people.”
As co-chair of the Privacy Security Committee on the IoT Consortium, a global group of companies helping to shape the public messaging about the IoT, Hunter explained in his presentation how he is working to establish a minimum bar for understanding the importance of privacy and security when developing IoT products.
“Firstly we want to help companies do the right thing for the consumer and, secondly, ensure there’s protection in place when things go wrong,” he said. “Nothing should be available online without security measures in place. Too often for developers, security is sprinkled on top rather than baked in and that just isn’t good enough when you’re dealing with personal data.”
Hunter also outlined how the IoT is not a revolution, rather an evolution of compute and about exploring the opportunities which exist in the software being developed – how to make it personal.
“The term IoT is a misnomer,” he said. “The internet was always about things connecting so we’re not reinventing the wheel but simply refining it for purpose and for individual users. Anyone developing new ideas in this sector would do well to research what successes have already been achieved and build on them – ensuring right from the start that security and the handling of consumer data are given the highest priority.”
