The data in the memory 200 can be set to a one-time non-recoverable clearing according to requirements. After the clearing completion determining module determines that the data in the mobile memory 200 is cleared, the clearing completion information is outputted to the clearing number determining module, and the clearing number determining module determines to clear. When the number of times does not meet the requirements, the control circuit outputs the clear information to continue to clear, and the clearing number determining module determines that the number of clearing times meets the requirement, and outputs the clearing completion information to the control circuit 330, and the control circuit 330 outputs the clearing completion letter.

The number of times can also be set to be cleared one or more times.

When the different security poles are selected for clearing, the clearing device clears the data in the mobile memory N times, and different secret poles correspond to different times of clearing N times.

There are three ways to clear the data in the removable memory:

1. Overwrite blank information N times to all storage areas of the removable memory.

2. Overwrite blank information N times to all storage areas in the mobile memory where data exists.
