Talking Facebook and infidelity on ABC 702 Sydney

ABC logoEarlier this morning I spoke about Facebook’s disturbing new “Big Cat” technology on ABC 702 Sydney, and here’s the audio.

Big Cat is the codename for an algorithm that can apparently detect with a high reliability whether your partner is having an extramarital affair, by analysing such things as their pattern of friend formation and communication, comparing their smartphone location with what they’ve said in posts — such as whether they’re really shopping or at the gym or on a work trip — as well as language cues, such as a tendency to avoid answering direct questions.

In a way, it’s a natural extension of MIT research from 2009, which showed that a young man’s pattern of friend formation could reveal whether he was gay — often before he even knew himself. Or Target (US) being able to determine when a woman had become pregnant from her shopping list — at least with 87% accuracy.

It’s the kind of stuff I talk about in my guest lecture to UTS students — which, as it happens, I’ll be updating and presenting this coming Monday 7 April.

As I discuss with breakfast presenter Robbie Buck, however, this is a little more serious than sending someone some discount coupons on a likely hunch. Facebook had better get this right, given that confronting a partner about an alleged affair is a serious issue.

I’m hearing that the Australia test locations will be the Brisbane / Gold Coast nexus or, more likely, Adelaide, for reasons that I explain.

One thing we forgot to mention in the interview is the reason for Facebook’s codename: “Big Cat” is for catching cheaters. Oh dear.

Talking ID and security on ABC 105.7 Darwin

ABC logoYesterday I ended up having a brief chat about identity, security and the concept of federated ID on ABC 105.7 Darwin. Here it is.

Breakfast presenter Richard Margetson had received a message from listener Heather from Tiwi, who’d lost her wallet. Amongst the hassle of having to replace all her cards, it was going to take up to six weeks for her new Medicare card to arrive — although she did get a new Medicare number to use straight away.

Margetson wondered whether technology might fix this. I set him straight.

Talking Tor and related matters on ABC The World Today

ABC logoMid-morning today I received a phone call from ABC journalist David Mark, who was after a backgrounder on the Tor network the lunchtime current affairs program The World Today. His call brought me the news of what appears to be a significant win in the battle against online child exploitation.

Fourteen arrests were made as part of Operation Round Table, which according to the (American) ABC, was an investigation led by the US Immigration and Customs Enforcement (ICE), US Postal Inspection Service and federal authorities in Louisiana.

The roughly 250 victims were spread across 39 states and five other countries — Australia, Belgium, Britain, Canada and New Zealand. Most were boys between 13 and 15. Two victims were 3 or younger, authorities said.

The pornographic images were shared on an underground website on the Tor network, an online anonymity network that masks the location of servers and conceals an Internet user’s location. The subscription-based website operated from about June 2012 until June 2013, had more than 27,000 members and shared more than 2,000 webcam-captured videos, mostly of young boys, authorities said.

There’s further material in the (Australian) ABC story, Australian victims among 251 identified in ‘members only’ child porn website.

The World Today ran Mark’s four-minute story, including comments from US secretary of homeland security Jeh Johnson, and federal attorney-general for Louisiana Kenneth Polite, as well as my own small contribution.

If you’d like some more information on how Tor works, and how users’ mistakes can lead to their anonymity being rather less effective than they’d hoped, my Crikey Clarifier: how the FBI hacked users of Tor, the ‘secret internet’ from August 2013 could be a useful starting-point.

Talking Bitcoin on ABC Sunshine Coast

ABC logoI did two radio interviews about Bitcoin last week, but unfortunately only one survives. This one, the poorer of the two.

The first one, on Monday 17 February for ABC 666 Canberra, was sharp, and I pulled off what I remember as being good impromptu explanations. But I stuffed up the recording. This second one, for ABC Sunshine Coast on Wednesday 19 February, was done after I’d followed the bottle of Sangiovese Barbera with a couple pints of cider after a long day of work. It’s less focussed.

This conversation with presenter Mary-Lou Stephens includes the word “cryptolibertarian”. It’s all a bit much. I even squeeze in a mention of Honest Beef.

The audio is also presented here without an introduction or a back-announce, because that’s how it was posted on SoundCloud.

Talking digital copyright on ABC 105.7 Darwin

ABC logoThe third radio spot I did about Attorney-General George Brandis’ comments on digital copyright was with ABC 105.7 Darwin on Wednesday 19 February. Here it is.

(“Third” you ask? There’s only been one other posted so far. That’s true. The second spot was with Dom Knight on ABC 702 Sydney on Tuesday 18 February. But I don’t have a recording for you. Sorry.)

This is roughly the same discussion I had on Spoke on Tuesday, but with presenter Kate O’Toole and after I’d drank a bottle of Sangiovese Barbera after I got angrier about the issues. So the concept of graduated response is a thing again, I allude to the iiTrial and so on. And yes I mentioned Rebecca Giblin’s research.

Talking Internet of Things on ABC Gold Coast

ABC logoThe fact that a bunch of technology journalists had gathered on the Gold Coast to discuss the latest tech trends caught the interest of the local ABC radio station. This conversation from Wednesday 19 February is the result.

Presenter Nicole Dyer and I ended up talking about the Internet of Things — and of course I mentioned the internet refrigerator and the internet rice cooker — smart cars, smart air conditioning, smart TVs and how they can be hacked. It’s a more lighthearted approach to some topics that I’ve discussed more seriously elsewhere.
