Mounted mode supports the following file systems: FAT, EXT4, EXT3, EXT2, NTFS (with fuse). Also the kernel must have fuse support or an appropriate eds kernel module. However mounted mode works only on rooted device. Mounted mode provides "on the fly" encryption: you can work directly with your encrypted files in any application. Normal mode supports only FAT file system. So you'll have to decrypt a file to some temporary location to open it in external application (except some media formats). In normal mode you can open a container on any supported device but it doesn't provide "on the fly" encryption. The program can operate in two modes: normal and mounted. TrueCrypt(R), VeraCrypt(R), LUKS, CyberSafe(R) container files are supported. You can never fully trust cellular phones because of all of the issues with untrusted modems and hardware, but it significantly improves your defense against data theft and device tampering.With EDS (Encrypted Data Store) you can store your files in the encrypted container to prevent unauthorized access to sensitive information. This process is the best that you can do for an Android device currently. (plus wait times when you enable FDE or copy garbage data, actual time can be a couple of hours if you include waiting.) Once you have a routine created for this whole process, it takes about 30 minutes to do before your trip. If I lose sight of my phone for a long period or suspect tampering, this whole process is repeated when I arrive at the hotel. This makes it so the devices can be wiped while I am traveling. This same data is cloned to the notebook PC that I bring along. Things like passwords, QR codes for 2fa activation, contacts, etc. I then place a VeraCrypt container on the phone that contains the information needed to restore the device if it is wiped again. I restore my contacts, install Lyft, install Signal Messenger, install Firefox Mobile, and reset two factor authentication for the relevant devices. The first thing I do is enable full disk encryption, this makes the device much harder to tamper with or otherwise read. Restore: Enable Full-Disk Encryption, Only Restore Data and Install Apps Relevant to the Trip This is less of a concern if you’ve enabled full-disk encryption in Android, because the data will be encrypted and the keys to that encryption will be thrown away when you reinstall the OS and set up a new instance of full disk encryption. Expect that some phone files remain no matter what you do. It is extremely hard to verify that any flash-based storage is truly fully erased because of this. Once you fill the phone with garbage data, it is safe to delete it all and use the free space normally.ĭo be aware that some files will still remain after this process due to wear-leveling. When you delete data off of your Android phone, the file is deleted from the index, but the file itself still exists until it is overwritten by new data. ![]() ![]() This is to prevent files from being recovered from flash memory. You then want to overwrite all of the free space on the device with garbage data. If you’ve installed a privacy build of Android like LineageOS, you can wipe the device with something like TWRP and reinstall the OS itself for the highest level of assurance. You can use the “system restore” or “factory reset” feature on a lot of phones in order to roll back all of your apps, settings, and caches to the factory defaults. Wipe: Reinstall OS and Overwrite All Free Space with Garbage Data I then move all of the data from my phone to the PC. This is done by connecting the phone to my PC, and creating a VeraCrypt container of the appropriate size. Backing Up: Contacts, App Data, Photos, Audio, Video Before Travel: I backup and wipe my devices, reinstall the OS, and install only the apps necessary for travel. (For cell phones, basically not at all.) This article covers the broad strokes, and I will write a detailed guide sometime in the near future. I then follow-up with rigorous steps to ensure that my information and devices maintain their integrity and that I can trust them with the same degree that I did before travel. When I prepare for travel, I take some steps to make sure that my protected data will not be read or otherwise mishandled by customs.
