(disclaimer: some of this was said in the "other" thread)
Ok, if the file itself is not DRM'ed why not just remove the JPG. Then it would be like a normal text file, and your reader would just display it.
Once again, using Public/Key private key means the user needs a way to put the private key into thier device.
The ONLY way to POSSIBLE do DRM properly is to use Public/Private key encrypt, but not provide a way for a user to embed the private key into the device. It would need to be either:
1. Embedded into the ROM of the device with technology like IronKey uses where there is no way to get to it. So, manufacturers would need to request the private key for each user before ordering... this would send the device prices much higher. It would also be hard to gift the device or sell it.
2. Use a hardware "dongle" like an IronKey or SIM card that was hack proof. This dongle would need to be inserted into the device in order to read/decrypt the file. This "dongle" could be an identity device and be more universal than just being used for eBook Readers of course. But, there would have to be some agreed apon standard (USB should work).
Still, method two above while workable with NOT stop piracy. It will only make it harder for people that legitamately bought there ebooks to read them.
(OK This is my last response to any type of DRM/Piracy idea/issue type threads. I "try" to promise.)
