Can you actually secure a Secure Digital card that you use in you PPC?
Is there software that will seemlessly do it?

Why is it called "Secure" Digital anyway?

The "secure" concept is really based on the little slideable notch on the left of the card. If you move it to the locked position, it is not writable. It's similar to a floppy disk.

There are also CPRM digital security concepts involved too. You can read more about it here: http://www.sdcard.org/sd_memorycard/index.html

The website information looks like SD cards have capabilities for enforcing DRM.

But not anything for protecting the data of a consumer.

Is there PPC software that can help me secure my SD card in the event it is removed from my PDA?

You'll want encryption software. Airscanner offers one free for personal use. You can find out more information here (http://airscanner.com/downloads/encrypter/encrypter.html).

i thought "secure" concept was based on encription capability ?

That too. It depends which way you look at it. The whole "secure" tagging given to SD cards have confused many over the years. :roll:

To be precise, the reason for the naming is because SD cards were going to heavily feature in the SDMI DRM initiative. As you can see from the SDMI page (http://www.sdmi.org/), though, the tech fizzled. I do believe that SD cards have unique IDs in them to help DRM policies be enforced, but the music industry isn't the one developing it anymore.
