Once a user swipes his finger on the sensor, the resulting fingerprint image is compared to a set of stored fingerprint images. Does anybody know if these stored images are encrypted (and if so, what type of encryption)? Are the stored images kept on the fingerprint chip, or stored somewhere on the phone? What about the data size of the fingerprint image (byte size, data layout)?
The only information I've been able to find is that the Galaxy S5 is using the Vfs61xx chip from Validity Sensors. The specs on this chip don't mention anything about encryption (unlike the VFS495).

Hi Folks,
is there a program that saves some confidential datas on my device? I need a program that saves the datas in a container and if this one is locked nobody can get eyes on the datas (for example pdf´s, jpg´s etc.)
Do you have any Ideas how to manage this or if there is a toll for this?
HI all,
i need the same, and need a programm to can edit my contacts/Telefon and SIM too.
Thanks all
Greetings

I've used Airscanner Encrypter in the past, did it's job very well.
http://www.airscanner.com/products/encrypter/
Description
Airscanner Mobile Encrypter is an advanced, attractive and easy to use encryption/decryption solution that both beginners and experts can enjoy. With its simple interface, you can create volumes that hold all your sensitive data, or use the interface to maintain granular control over the encryption/decryption at files or folder level. Using a fast and secure 168-bit 3DES protection, the Encrypter balances speed/process use/battery life for an efficient, yet usable encryption/decryption functionality. In addition to manual control, the Encryptor can be configured for auto-encryption after a specified time to ensure your data is encrypted if your device sits unused. Passwords can be set for each file, or you may choose to use one global password to lock/unlock single sign-on, transparently encrypted volumes.
Version 2 now includes a secure file wiper to shred or "bit wipe" the data stored on built in memory and external memory cards on your Pocket PC. You can select the number of passes to overwrite up to the DoD recommended 7 passes. We have successfully tested it with PDA forensic tools.
Download this innovative product and start protecting your mobile device - quickly and easily.
Features
* Granular encryption and decryption at the individual file/folder level.
* Transparent, single sign-on encryption.
* Automatic volume encryption after a user-defined number of minutes.
* 168-Bit DES encryption Support for encrypted volumes.
* Secure bit wiper/file shredder -- for built-in memory and external cards, too.
Resco Explorer does it for me......
I have Googled this subject and not found a satisfactory answer. Is it possible to do a whole disk encryption with truecrypt or another program on the HD2? The setup I imagine would encrypt the HD2's internal memory and SD card. Anybody know if this is possible or would the bootloader have to be re-written to support this feature?
Sent from my HTC HD2 using XDA App
for what reason?
nevarDeath asked a very good question
Well, I think shouldn't be too different to a conventional Linux install using any Linux encrypting frameworks, probably dm-crypt and crytoapi are the preferred ones (support is given by the kernel itself).
You can encrypt almost everything, root filesystem (you will need a special initrd AFAIK), user data and swapfile. What I am not so sure is how much would be the power consumtion increase, surely for an encrypted data partition accessed not so often is not such an issue.
One of the uses I can think about is keeping there your passwords and so, just in case the phone is lost your accounts are safe. Maybe the browsers data should be encrypted as well, I am not sure where they store login data (i.e. ebay or paypal).

I was considering storing financial and personal information on my phone in the form of files and realized that though the fingerprint scanner is ok to prevent the casual browser from logging into the phone when it is left unaccompanied, a real hacker could easily see whats on there with very little effort.
The Atrix on the face of it looks like a secure phone with the fingerprint reader; however XDA users would know that nothing prevents a thief from entering fastboot and mounting the files and folders to see whats on there. No security app can prevent that.
Using the android built-in option and encrypting the entire sdcard is NOT an option for me at this time. I think its going to slow down the phone operation if the OS files are encrypted and each time it needs to decrypt each and every file and folder. Also it may present issues when testing new ROMs. (And I am dual booting - so my extSD also has a ROM which I would not want to slow down anymore than it already is)
So I searched for methods and apps to encrypt individual files or folders on the Atrix. There are quiet a few in the market and a few are free as well with good reviews. However most -even the ones with the best reviews seem to be just changing the file name and location and not doing real encryption. Also most of these use proprietary algorithms or methods to hide information. A really good app would be one that uses an open source algorithm to encrypt the files and folders - so that the algorithm would be tested and verified as being strong by the world.
Also another requirement was for the ability to frequently sync and update the files on the phone with the PC. The app should have a PC equivalent - that is the file can change on my PC and then I should be able to sync the changed file with the phone in some automated way.
Yet another requirement would be the ability to quickly encrypt and decrypt huge audio or video files. A few good apps could encrypt small audio and video files but not files of size 1GB or more. The apps would either freeze after some time or not encrypt them at all.
Finally I was looking for an option by which the files if I unencrypt them to be available across all apps for the duration of that session - not just in the app that encrypts and decrypts them. So in other words, once I enter the password, the folder should be mounted and available in any app that can browse the phone - until I decide to end or unmount the encrypted store.
I found only Cryptonite doing all of this. Unfortunately Cryptonite does not support Truecrypt containers on Motorola phones. There is some info here on the truecrypt port to android here:
http://forum.xda-developers.com/showthread.php?t=872297&page=7
However I could not get it working with the Atrix. Has anyone had success getting Kryptonite and Truecrypt to work on the Atrix?
Cryptonite also supports Dropbox, but I am not a big fan of storing sensitive info in the cloud - however well known the company is.
Cryptonite does support encFS and I was able to successfully create encFS encrypted folder on my Atrix. I would have liked to have TrueCrypt than encFS, just because I have been reading that Truecrypt has better overall support.
The method I use now for storing and synching encrypted information is:
for the first time only: create the encfs folder on the PC, then mount Atrix as a USB drive and copy the encrypted folder to Atrix.
To sync the encrypted files with the PC, I have to connect the Atrix as USB drive, open EncFS on the PC and select the folder on the Atrix to mount as a drive volume. Also mount the PC encFS folder as another drive. Now sync with the PC using any sync tool like MS SyncToy.
I went through a lot of searching and came to this which I think is good enough at the moment. I would like to hear if anyone else has a better app or method to secure and sync secured files on the Atrix - especially if you have got Truecrypt to somehow work on the Atrix. And I post this so that is anyone else needs this information, it is here.

I don't know about the rest of it, I never used any strong security on my phone nor do I intend to, but I think you shouldn't ever expect to be able to "quickly encrypt and decrypt huge files". You're pretty much asking for impossible here. It's like asking to build a full-featured house, furnished and all, in 30 minutes or less. A lot of data will always require a lot of time to process. Heck, even, say, straight plain copying such a file to a computer would take quite a while.
No.
Your not going to get business class security on your atrix, or any current phone most likely.
LUKS manager is the closest thing to legitimate encryption (not gimicky BS) i have seen, but it has some fatal flaws.
Passwords and such are safe and easy to store with KeePass, which is also on windows/linux for syncing and has years of reputation (also free/open source). It isnt for files though.

Correct me, because it just hit my mind that it would be kind of advantageous not having an expandable memory. For example, if our phones were to be stolen by an average thief, it would be quite easy to access micro sd data, regardless of the password protection on the phone. Whereas, for non expandable phones, the data isn't accessible unless one has unlocked the phone after connecting.
Well anyways, my question here is that is there any foolproof method of protecting personal data on phone? Also, can whatsapp be relied? Any more methods you can think of can be added below.
First being that don't use cloud services for private data. (something we learnt from today's leaks ) Not that I ever have, for sharing photos with family, I've always encrypted my data (with aes 256) before uploading on mediafire. At least it gives me a little piece of mind.

In KitKat I saw an Encrypt Phone option which is really awesome for internal storage.
Moreover Google if forcing OEMs to remove microSD card slot so that People are dependent on their cloud services.
Google was us to be fully dependent on them.
Which is not so awesome .
We listen many times about ROM & RAM but what is the difference between those two words ?
There are a big different between ROM & RAM
ROM stands for "Read-Only Memory", it is a type of built-in memory which be used in computers, Mobiles and other electronic devices and as its name indicates, it is used only for reading data from it, You can not write to it or change it. The manufacturers use it to store devices data.
RAM stands for "Random Access Memory", it is opposite of ROM as it is used for reading and writing so this memory is available for operating systems, programs and processes to use when the computers is running.
That was a brief about the difference between ROM & RAM. I hope it was useful and you can learn more information about this by searching for "ROM & RAM" on Google :good:
Difference Between RAM and ROM
RAMROMRAM is volatile memory, which could store data as long as power is supplied.ROM is a nonvolatile memory, which could store data permanently.RAM is read-write memory, data can be retrieved and altered.ROM is read-only memory, data can be read-only, we cannot alter the data.RAM is faster in speedROM is slower in speedRAM is expensiveROM is cheaper than RAMThe CPU can access data stored in RAMThe CPU can not access the data stored in ROM unless data is stored in RAMRAM is used as cache memory in the computerROM is used as firmware by microcontrollersRAM consists of four components which are memory matrix, address decoder, input buffer, and output bufferROM consists of two components which are Decoder and OR gates
Read this article to learn the difference between RAM and ROM.
RAM is Random Access Memory, it's fast temporary storage, used by applications and the operation system. ROM is Read Only Memory, the EEPROM chip, Electronically Erasable Programmable Read Only Memory, the BIOS, basic input and output system, is stored on it, the control panel that has the drivers used to communicate with all hardware firmwares, gets signals from them, and sets certain variables, based on the customization stored on the CMOS Battery and the signals being watched for, some flash a different BIOS on the EEPROM chip in order to enable and disable settings to allow for a having a virtual layers, allowing for virtual drivers/kexts and hardware spoofing, in order to install Mac OS on PC hardware, it'd be called a Hackintosh. However, in Android terms, the ROM is the operating system image, like Windows has an ISO file، developers have it customized to add and remove apps and features on the on the stock OS image. I hope this was helpful
