#Apple’s #TouchID implementation misguided

Whoever is guiding Apple’s TouchID implementation is severely misguiding Apple and the public who uses it. 

The idea behind biometric security is that it is infinitely more difficult to crack than a PIN or Password. Where a password or passphrase in today’s marketing techno-lingo may be composed of eight or more ASCII characters, a biometric signature may have tens of thousands of combinations. Even a 30 character password cannot compete with such a combination. Not that it can’t be broken, but it would be more difficult and time consuming. And on a device that can lock and/or wipe itself after a number of incorrect tries, it should be IRRELEVANT.

( Now let me state for the record that a PIN in and of itself, does NOT constitute a password or passphrase in my opinion. If a vendor such as Apple or other security providers allow their users to consume PINs, I would allow for dual authentication on every boot. )

I also understand the reasoning behind dual token authentication.   “I go to work and I can use dual tokens to sign in in the morning, and work all day. In a multi-tenant managed environment dual token is a great authentication method when managing different tenant infrastructures.”  

I can also think of the following industries which can benefit:

  • Nuclear plants
  • Munitions depots
  • Utility distribution grids
  • Aircraft cockpits
  • Banks

I can also understand use of the dual token as implemented by Apple in the following circumstances:

  • When booting, in a ‘motion-less‘ profile;  that means NOT while in a moving vehicle, and not during physical movement such as walking. Those are dangerous activities to be engaged in while trying to enter a passphrase. Legislatures are passing law after law to curb such activities, while Apple is actively opposing the legislation.  

If Apple wants to implement a dual authentication on boot then allow the user to set the elapsed time, say one to four weeks. 

  • Under no circumstances should dual authentication be required after a boot when using biometric authentication:
  1. Not when I’m shopping
  2. Not when I’m driving
  3. Not when I’m walking or jogging (not that I jog)
  4. And certainly not when I’m in line waiting to pay, unless the transaction is over a limit, I, the user has set

Lest anyone thinks I’m beating on Apple, I’m not. This applies to all security implementors in any company and product.

Rejuvenation of TenGo soft keyboard from Windows CE days for mobile devices

The best soft keyboard for mobile devices in Windows CE days, was TenGO.  This was a T9 type, predictive type-ahead keyboard, however, it provided for two alpha-buttons on each keyboard row, see illustration.  To type you simply entered the word by pressing one of the three six alpha-buttons, and the predictive type-ahead engine did a really cool job of figuring out the word you wanted to enter.  If it was not in the dictionary, you could select the actual letter in the alpha block, by pressing the soft key the number of times the position of the character represented I the block.  For example if you wanted to enter the character ‘d’ outside of the predictive type-ahead engine, you would press the ‘asdfg’ block three times.  Once a new word was entered it went in to the user dictionary and was available to the T9 engine at the next entry of that word.

I hope that the maker of this keyboard, will resurrect it now, not only on iOS but for Windows and Android mobile devices.  It was awesome.  TenGO are you listening?

iOS 7 Home Screen Editing is limited

I’ve found, to my dismay, that iOS 7’s Home screen editing has a very finite number of moves it will allow, before it dumps all of your changes and reverts back to what the menu structure was originally. So if you start making changes, and you don’t occasionally press the home button to save them, it appears the editor’s buffers fill up, and it just loses all of the changes since the last save.

It would be nice if there were a warning when getting close to the buffer limit.

My feedback on iOS 7

I have an iPad 3, and an iPhone 5.  I’ve installed iOS 7 on both.

Generally I like the improvements that iOS 7 has brought.  There are some items, I am not happy with however, especially on my iPhone 5 (I also have an iPad 3):

 1. Bright background colors on home menu icons The bright colors make it very difficult to distinguish the application thumbnails Perhaps next version, Apple could allow changing the menu icon background colors manually  

2. Really thin fonts The thin fonts make my eyes hurt;  I have trouble trying to read the home menu icon text;  the same for the time on the lock screen Perhaps next version, Apple will allow changing of fonts or at least font sizes/boldness so we can read the screen without squinting

3. Stick symbol icons, i.e. in Safari, Mail and other apps Not as bad as the my other complaints, but again, it makes it difficult to ascertain the purpose of the symbols, because I can’t see them without concentrating
