Last year I wrote some client (Android and iPhone) and server (Apache and Microsoft Server) code to support two factor authentication using a TOTP. I’d love to tell you more, but I cannot as it was (a) work-related and (b) a retelling of the tale would require mentioning other people who might read this blog in an unfavourable light.

Demographics

I think I’ve had most of the problems listed in Q2SQ1! One other one I had was that I wanted to cancel a web hosting service, but in order to do that you had to send a letter (Fax would not do!) at least a set number of days before a billing cycle. I’d tried to get in touch with customer service to sort out a few matters, but as the date rolled round I just cancelled my credit card payment. They sent me payment reminders for about six months, but I just ignored them all and they eventually gave up. I had paid for all the services I used, and they had tried to charge me an extra month or two for services I couldn’t use because they had suspended my account.

I’m quite happy using the free Microsoft Security Essentials, myself. However, I’ve just moved to Linux, the Crunchbang distribution; in fact this is my very first survey typed through the Notepad-equivalent editor GEdit, to which I’ve added a self-written macro that builds the tables you see below. I might upload it to GitHub sometime soon…

For me the storm was a bit of an anti-climax; we had a few hours of horizonal rain, but nothing out of the ordinary compared to when I grew up and we used to have two or three days-work of Atlantic gales to handle. I always feel the same way with typhoons; they can be nasty when they pass straight overhead and you are in a mountainous area or flood plains which amplifies the effect of the rain, but preparations, tying everything in the garden down, always feel like a waste of time.

Demographics

Between the 7th and 12th of March 2012 1,033 members of the goo Research online monitor group completed a private internet-based questionnaire. 52.5% of the sample were male, 16.4% in their teens, 17.9% in their twenties, 21.7% in their thirties, 16.2% in their forties, and 27.9% aged fifty or older.

Here’s a scam virus advert on a tablet:

I seem to remember translating the previous survey, but I cannot find it on the site. Perhaps I got half-way through and decided it wasn’t interesting enough to be published?

Anyway, I’m curious why tablet security is increasing but smartphone staying static. One factor in the tablet rise is no doubt due to Android increasing market share, and curiously enough if all the extra 36 tablet owners in Q1SQ were non-iOS users, and all of them used security software, then the rise from 42.1% to 55.2% is explained, but I’m sure that’s just a numerical fluke.

Research results

Q1: Which of the following devices do you have? (Sample size=1,033, multiple answer)

Notebook, netbook, ultrabook	74.1%
Desktop computer	50.5%
Smartphone (to SQ)	42.8%
Tablet (to SQ)	13.8%

Both smartphone and tablet ownership are up about four percentage points since the previous survey. Unfortunately, the “none” figure was not reported.

Q1SQ: Regardless of being free or paid for, do you use security software or services on your smartphone, tablet? (Sample size=see below, multiple answer)

Demographics

Towards the end of 2012 316 people between the ages of 18 and 59 who had changed from a feature phone to Android in 2012 completed a web-based questionnaire, although it is not clear how they were selected or if the survey was private or not.

Note that Galapagos in the title comes from a frequently-used term for Japanese feature phone which have evolved in isolation to devices uniquely suited for their environment, but unable to establish a foothold anywhere else in the world.

Demographics

Between the 5th and 15th of July 2012 3,000 randomly-selected Japanese citizens were selected from resident rolls and approached for face-to-face interviews. 1,956 people agreed to take part, but a further demographic breakdown was not provided.

I’m not really sure why the figures for fear of foreigners have changes so dramatically for the better in the last six years, and I’m not sure how I would go about finding out the reason behind it. However, it does also seem clear that the new bogeyman is Reefer Madness, especially as round about the time of the survey there was no end of stories about a current social problem of legal highs, dubious cannabinoid derivatives sold as incence in a multitude of shops in Japan’s big cities.

Demographics

Sadly, to find out the full demographics I suspect one has to buy their paper magazine Senden Kaigi, which in their 15th May 2012 edition featured an article entitled “Consumer Psychology in the SNS-facilitated mutual surveillance society”, of which this report is a digest. In Q1, the 2008 survey was carried out in December of that year with 2,077 respondents, and this year’s survey was in April with 2,214 respondents, all from the usual goo Research online monitor panel.

I’m reluctant to check in when out and about in town – I’ve only attached location information to photos when I’ve been passing through commuting home; there was an interesting article a while ago about someone in Tokyo who used that sort of public information plus Twitter to find two people in real time through their mobile presence.

I wonder what the reasons are for smartphone users being more likely to reveal information – is it that smartphone apps make it easy and fun to do, or is it that the people who want to reveal information tend to use smartphones? Perhaps if one buys the magazine one can find out!

Over the 30th and 31st of May 2011 1,573 smartphone owning members of the goo Research online monitor panel completed a private internet-based questionnaire. 52.4% of the sample had an iPhone, 47.6% an Android-based phone; 1.0% had had their smartphone for less than a month, 12.5% between one and three months, 28.3% between three and six months, 25.3% six months to a year, 22.8% for one or two years, and 10.1% more than two years. 71.9% of the sample were male, 16.7% in their twenties, 34.6% in their thirties, 29.9% in their forties, 14.9% in their fifties, and 3.9% aged sixty or older.

I’m really surprised about the very low disclosure rate of who one works for, but it does very much ring true with what people who were sceptical of whether LinkedIn could make it in Japan said.

Next there was a radar chart plotting application genres versus percentage who had used each type, for iPhone and Android users. Unfortunately there were no concrete numbers, but some of the interesting results were that every genre bar wallpapers had more iPhone users, most likely because the iPhone doesn’t allow you change wallpaper. Games were most popular on the iPhone, but for Android it was search and other tools.
