DRM over SD Cards safe?

I'm trying to implement a DRM based around SDCard's serial number in Windows CE. There are a few question I'm concerning.

  1. Is SDCards' serial numbers unique like the MAC address ?
  2. In Windows CE 6 (as some source codes are available, can someone make a SDCard Reader driver that reports wrong serial number. (A number that is not coming from SDCard but an fake number).
  3. Can serial number embedded in a SD Card be changed by some sort of JTAG or flashing?
Solution

  • Can someone create a driver that reports a fictitious serial number? Absolutely. You can create a new SD driver to do whatever you like for any specific command.
