Cyber crimes are increasing at a rapid rate and one of the biggest problem is the data loss or the data theft. Since smartphones owns now the sensible data it has to be secured. Recently Google announces that Android 6.0 devices will have a Encryption.
One best or way of preventing data theft, eaves dropping is Cryptography in which the text or the message changed in the format that is unknown to any person other than destination.
Simple statement for Encryption is that you can lock your house and then you share the key with your one friend, so now only you and your friend can access your locked property. The same principle applies in Encryption.
Android 6.0 supports Full Disk Encryption (FDE). FDE is the mechanism of encrypting the whole data that resides on the disk and then decrypt them as and when required. The thing is that the data will be encrypted even before they are saved to the memory.
The key will be provided by the user and the key usually is the password. This mechanism will surely prevent data theft from happening and Android supports encrypting their devices
User private area (/data) and
SD card (/sdcard) data.
When considering the disadvantages of this mechanism the biggest problem is that since it requires encrypting the data and decrypting again, it requires time and on the fly mechanism will make the system little slower to respond.
This can be used by the users who wants complete shield to their data and other users can go with the passcode or pattern lock to their screens.
P.S : The post is to create awareness and not to create any negative impact.
