A little less privacy is worth a little more security, says internet founder

Vint Cerf talks wine corks, Google Glass and Prism

Aptly termed one of the founding fathers of the internet, Vint Cerf certainly acts the part.

Now a youthful 70, Cerf remains a bundle of enthusiasm - handling the press with a smile and launching into interviews with gusto. He's a London resident for a few months and has made the journey south of the river Thames to be the main speaker at the O2 Campus Party in the giant tent formerly known as the Millennium Dome.

Cerf is one of the creators of the internet. Along with Bob Kahn he created the TCP/IP protocol that underpins the web, he helped form ICANN - the non-profit body that oversees the internet's unique identifiers and ensures that it doesn't grind to a halt - and he worked on ARPANet, the U.S. Department of Defense's precursor to the internet.

Now, Cerf works for Google as VP and Chief Internet Evangelist, a role which is perfectly suited to a man who can switch between passionate appeals for ISPs to adopt the IvP6 protocol and anecdotes about how the internet of things can help him gift bottles of wine from his cellar that have not been kept at the correct temperature.

Cerf was speaking at Campus Party Europe - an ambitious week-long technology festival staged by Telefonica at The O2, London.

The internet has been getting a bit of bad press lately, with governments' Prism reach into our everyday online lives still a major controversy. But, as you might expect from someone considered for the Chief Technology Officer of Barack Obama's tenure as president, Cerf is less polarised in his views.

"When the internet became available, we got all of the general public including some unsavoury characters that didn't have your best interests at heart, so we got a lot of bad things showing up on the net in addition to the overwhelming positive value that is available," he told TechRadar.

"Small numbers of people are now having enormous impact on a national scale. So the problem here is that historically if we had a national attack going on it was fairly visible because you could see movement of troops and so on.

"But, in the 1970s we started to see a very different trend and now its even worse because we have small groups of people who have access to the internet who are capable of doing a number of bad things.

"So there's a lot of worry about how to cope with that and the important problem is that security isn't reacting after a bad thing has happened, security is preventing the bad thing from happening.

"If it can come from anywhere, if it can come through the internet, and if it can come from small groups of people who are essentially invisible until they do bad things then the question is how do you respond?

"[By and large] we elect governments who will look after us and we even give up a degree of privacy in order to be protected. This is not an apologia for what the NSA is reportedly doing, but it's a motivation for understanding why you would want to watch as much as you can in order to detect some of these attacks before they happen."

PRISM - an 'unsettling' turn up

Cerf accepts that the level of surveillance is "unsettling" for the general public: "It's possible to go overboard and in the current situation and the general public in both the US and other parts of the world were not fully aware of this kind of surveillance and in some ways that's part of the problem."

Interestingly, Cerf feels that the British response to the Prism revelations was lessened by the 7-7 attacks and how surveillance played a part in the capture of some of those responsible.

"Ironically, here in the UK the reaction was more muted than in other parts of the world because you have experienced the utility of observation and CCTV cameras," adds Cerf, edging into controversy for perhaps the only time in the entire day.

"The value of that was shown - I thought - in the speed of capture of the people who bombed the tube in 2007.

"So here we are struggling to balance the safety of society against the privacy of the individual and we don't want to be at the extremes."

Google Glass - a powerful future

As the interview moved on to lighter topics, Cerf was happy to field a question about the privacy implications of a device coming from his now-employer - talking up the potential of Google Glass rather than focusing on the privacy implications of wearable tech.

Google Glass - privacy implications, but powerful

"First of all we should say that the recording is not continuous because there's not that much memory in the device," he added.

"Ultimately having something very visible that shows the Google Glass is recording either in audio or video will probably be necessary - that's certainly what the feedback suggests.

"I find the idea of Google Glass very powerful in the following sense; What is happening is that the computer can see what you see and hear what you hear.

This makes the computer or software a partner in real time and in context so I can do things like point to something and say 'what's that' or point to a bottle of wine and say 'what are the tasting notes on that wine'.

"Because the computer is in the same environment it can see what I'm seeing."

Internet of Corks and Things

As he addressed the Campus Party crowd, Cerf's interest in the internet of things (devices on the internet providing data that allows us greater control and transparency of information) was clear.

After launching into an anecdote about the dystopian future of internet connected fridges, Cerf explained how he was using cheap connected chips to change his own household life.

The internet of things - a bad term for an exciting future

"I happen to have this sensory network running at home - these little sensors run on two AA cells and they last for about a year - each one is about the size of a mobile and its monitoring temperature, humidity and light levels in the house every five minutes and that information is transmitted to a server down in the basement.

"Now these little sensors are also network nodes - and they are forming a mesh network on their own and they change their connectivity depending on what the network linkages look like so the information is sent through the network to the target.

"At the end of the year I have an accumulation of real data about how well the heating, ventilation and air conditioning has worked - this is proper engineering data and it means I can figure out how to adjust the systems.

"So before you open the bottle you would interrogate the cork and if that's the bottle that got up to 75 degrees that's the bottle you give to someone who doesn't know the difference."

Cerf, clearly something of an oenophile who references his wine several times throughout the day, has an even more important project that he is working on.

"It occurred to me that in the case of the wine cellar that this is a very important room in the house because there are a couple of thousand bottles of bottle in there. I need to keep it below 60 degrees fahrenheit so if temperature goes up over that because the system fails I get an sms on my mobile.

"I thought about this and realised that, seeing as I can also tell if the lights have gone off and on I might be able to figure out if someone has gone into the wine cellar while I was away. So my next project is to put RFID chips on each bottle and then have a sensor so I can take inventory instantaneously to see if any bottle have left the cellar without my permission.

"I was proudly explaining this to one of my engineering friends and he said, 'There's a bug,' so I said, 'What do you mean there's a bug?' and he replied: 'Well you could go in and drink the wine and leave the bottle.'

"That means I now have to put sensors in the cork and if you are going to do that you may as well sample the esters - which is what makes the wine taste the way it does.

"So before you open the bottle you would interrogate the cork and if that's the bottle that got up to 75 degrees that's the bottle you give to someone who doesn't know the difference."

Big data, big issues and big thoughts on the future, Cerf is showing no signs of easing down, and that is no bad thing for the rest of us.
