This module comes into play if the user wants the data to be stored in the car instead of wiping it off once the car is switched off. There may be cases when the driver has to go to the same destination the next day also. For example, the driver goes to office all five days in a week. He may think why to pull the data every day from the cloud. Rather keep the data in the car itself till Friday and wipe it off on Saturday. But the data has to be secured once it is inside the car and therefore it should be encrypted. This means that a hacker even if he gets the data also should not be able to make any use out of this.
