The mobile web and your personal information

James Rosewell writes:

The mobile techie community has known about mobile networks and indeed some handsets providing unique information about mobile devices and customers for a long time. Collin Mulliner, a graduate student at the Technische Universitat Berlin, has recently bought the issue to the attention of the public during a talk at the CanSecWest conference in Vancouver.

Information such as IMEI and Mobile Phone Number is passed to web servers accessed by a mobile device or Mobile Network Operator (MNO) proxy server in hidden fields called HTTP Headers. The amount of information, format and ultimately usability of the information varies between MNO and mobile device. Practically, the inconsistency of the information makes it of little practical use to web sites. The apparent random nature of the information provided indicates MNOs haven’t really thought through how they’re configuring their gateways and proxies.

The following table shows the HTTP Header (hidden fields) provided by a mobile request received at thefonecast.com yesterday. Notice the x-up-calling-line-id field that contains the mobile number of the requesting device. (We've removed the mobile number from this example). This particular request was provided via the ZXWAP Gateway from ZTE.

x-up-calling-line-id
XXXXXXXXXX

The real point is that MNOs are seen to be taking liberties with customers personal information. There are many practical uses to providing this personal information “behind the scenes”. For example:

·    A web site that requests a telephone number can default the telephone number field to the mobile number provided by the mobile network reducing the amount of data the user needs to enter.

·    Multiple interactions can be related to one another without requiring explicit authentication.

On a darker note, once a malicious web site has a mobile number, the text message inbox would become the next target for spam.

Many people will be unhappy with this personal information being provided without consent. MNOs need to establish a clear and consistent policy around the dissemination of such information and ensure customers are in control of the personal information their mobile phone is giving out.

What my granny taught me about online shopping

Mark Bridge writes:

When it came to telephones, my granny was an early adopter. She had a landline phone for as long as I can remember - and that’s quite a while when you consider the town only got an automatic telephone exchange two years after I was born. Recent research has now suggested that my granny was also well ahead of the game when it came to consumer behaviour.

Cortado offers a secure 'cloud desktop' without unnecessary restrictions

Mark Bridge writes:

Security is often a balancing act - and security on mobile devices is no exception. If procedures and processes aren't tough enough, you'll compromise the security of the information you're protecting. But if your security is too tight or if it seems too complicated to an end user, that user is likely to find a way round your security by doing something else instead.

Last week at The Fonecast: 7th November 2011

Mark Bridge writes:

I’m reminded of a sketch from BBC TV’s ‘The Young Ones’ in 1982. The four horsemen of the apocalypse are waiting around.

“What’s new?”, asks Pestilence. “Microchip technology”, replies one of the others. “That’s quite a new thing, isn’t it?”

Quite new. It’s probably the best description for much of last week’s mobile industry news.

Mobile technology publication becomes the first NFC-equipped 'smart book'... sort of

Mark Bridge writes:

Atria Books, part of the Simon & Schuster publishing family, has released what it’s calling the first-ever smart book. A thousand copies of ‘The Impulse Economy’ by Gary Schwartz will have an NFC sticker attached, providing a web link to book-related content.

Hmmm. That’s not really a smart book, is it?  The same kind of logic means my NFC credit card turns my wallet into a ‘smart wallet’ and transforms the pocket of my jeans into ‘smart jeans’. It means my NFC-equipped smartphone is a smart smartphone.

Last week at The Fonecast: 31st October 2011

Mark Bridge writes:

In the world of retail, you can’t move for Hallowe’en puns at the moment. You know the kind of thing. Spooky offers. Frighteningly low prices. Missing our deals will haunt you. There’s not the ghost of a chance we’ll shift these PlayBooks unless we cut the price.
