Controling access to the data on SD card / CF Card

[dev guy]

hi

I want to put certain files on the SD / CF card. When a user tries to access
a. the card OR
b. a file from the card

I want to pop up a login dialog box. (My app on PPC will have login ID and
Pwd stored.) and verify the user id.

1. How this can be accomplished?
2. Is there a SDK available for SD / CF card vendors?
3. Or the API is built into the WinCE / Windows Mobile 2003 API (which can
be accessed from Compact Framework) ?
4. Can someone suggest better alternative to controling access to the data
on such cards (if there is another better mechanism)?

Thanks and warm regards

There is no way to secure file access on a Pocket PC. It's possible through
vanilla CE by modifying the filesystem driver, but it still wouldn't prevent
someone from putting the card in another device or PC and simply reading it.
You're using an unsecure media form. Consider encrypting the data instead.
