Abstract
The present disclosure prevents the leakage of user data by preserving user data working not in an electronic computing machine. A part of a storage area of a main memory of a user terminal is used as a RAM disk. User data working is encrypted and stored in the RAM disk. The user data stored in the RAM disk is sent to a network storage, the RAM disk and the network storage are synchronized. Since the user data is controlled by using a driverware technology inside the electronic computing machine, and sent to the network, therefore the security is ensured.
