What is the best method to provide security to my device,am disabling ssh,root access etc , but i need sdcard security also,
in sdcard loads my application code, if any other persons open sdcard he will not understand my code.
This is my costumer requirement , please any one help me on this.
You could re-partition the SD card and create a new empty, encrypted partition. Then you put all your applications and data in this partition with the rest of the usual/generic Raspbian in the first partition, as normal. You can also encrypt the whole / partition (but not the /boot partition). You can even do this on an already setup Pi.
(a) You/Someone will need to provide the password at boot time every time the Pi is booted. Unattended reboots will not be possible. This may or may not be acceptable to you or your client.
(b) It will be slower than it already is.
(c) google it - the first 2 links I got told me all I needed to know.
(d) You have not thought of this yourself. If I were your client, you'd be sacked by now.
