• Secure storage (flash media) for full-time automatic encryption; easy wipe

  • Use LUKS/Cryptsetup project code either integrated or via external app

• SQL Cipher/metadata encryption for Media Store

  • Encrypted sqlite using symmetric key
  • override content URI handling by built-in Media Store

• Metadata signing for verification/reputation

  • need to discuss the use case for this more
