A couple of weeks ago, the mere mortals who lead the voracious giants of technology -- Google and Apple -- announced that they were striking a blow for protection against NSA spying by making "encryption" the default on Google cell phone software (which is used on most cell phones) and THEY software used on Apple mobile devices.
This affects equipment like the ubiquitous cell phone, although it is also relevant to some handheld computers and similar portable equipment.
The idea would be that your data on these devices would always be encypted -- appearing as unintelligble nonsense to anyone looking at it without a key to "decrypt" it. You use a password and, bingo!, you can read what you stored. Without the password, it looks like a bunch of bizarre symbols. This would now be the "default". While you could encrypt if you chose to up to now, you will now have to consciously choose not to; encryption will be automatic unless you turn it off.
