Abstract

The invention discloses an electronic storage device and a data protection method thereof. The electronic device is electrically connected with a host and used for storing data of the host. The date protection method comprises the following steps of: providing a standby battery which is arranged in the electronic storage device and used for providing electric power needed by operation of the electronic device when the host does not provide power for the electronic storage device; setting a time set value; transmitting a login event to the electronic device; judging whether the electronic storage device needs to protect the stored data in the electronic storage device according to the time set value and the login event through the electronic device, and if so, the electronic storage device protects the stored data. A protection mechanism of the electronic storage device can make judgments according to the time set value and the login event or according to whether the login event reaches a login failure threshold value so as to protect data stored in the electronic storage device from being stolen by others.

Description

【Technical field】 [0001] The present invention relates to an electronic data storage technology, and in particular to an electronic storage device and a data protection method thereof. 【Background technique】 [0002] With the development of electronic data storage technology, storage devices are being used more and more widely. The data in the storage device may be important or confidential, especially the confidential data of military units or government units. Storage devices should be able to prevent unauthorized access, destruction or theft of data by any person. At present, there are already several encryption specifications or standard protocol specifications of different levels of encryption specifications. In practice, electronic data protection is not enough to rely on regulations alone. In order to enhance data security, storage devices still need to be equipped with other protection mechanisms to prevent data from being stolen by outsiders. 【Content of invent...
