I guess it depends on how you define secure?

If you mean 'nobody else can access the data if they get a hold of the card' ... there are many articles on the web discussing this issue - here's a decent (but slightly dated) one: http://www.windowsecurity.com/articles/Securing-Pocket-PC.html

There are a LOT of app's which will provide you with varying levels of encryption for your data - Resco Explorer has an option to encrypt, for example.

Use google (or your preferred search engine) to search for "pocket pc" and "security" (or perhaps "encryption") and you'll get plenty of hits.

I must point out though that we are talking about an extremely portable device. A PDA is just so easy to steal! An SD card is even more so. So if you are talking about data which really MUST remain secure ... you may well be better served by not putting it on your unit in the first place.

Hi
Actually we wanna do a simple thing.
we wanna put our application and data on SD card and allow access to this storage only to someone who have right to do it. (it isn't top secret :))

SD category 3 of levels of SDMI security requirements will be fine for us.

But as I understand - there is some problem with it. It is a little bit strange - because every normal SD card has to provide this feature (and it is), but just there is no any suuport of it from OS? even there is no some 3-rd part File System Drivers?
It isn't sounds so hard to implement.

Why do I feel like we got gipped again?

I believe SD is a scam over MMC cards just like 1.44MB 3.5" floppy disks was a scam over the 720KB version... :x

I did some research into SDMI last year, as a part of a contract I was on. I've dug into my notes and found this:

It may be of some use to you. Probably not ... frankly I find the whole approach of DRM to be a joke :D
