After the computer is started, the wireless module 12 receives a message from the network, such as a short message, a command of packet data, or a mail, so as to obtain a command of clearing data sent by the user.

S32: the control chip 10 activates the hard disk 14 and performs an operation of erasing data.

In the process of clearing data, a user can send a command of clearing data through a network terminal, such as a mobile phone, a computer connected with the internet and the like, after the computer is lost. After the computer is started, the wireless module 12 receives messages from the network, such as short messages, packet data commands or mails, so as to obtain a command for clearing data sent by the user, and clear the data in the hard disk 14, so that the data of the user is kept secret, and the disclosure of secret is prevented.

After the computer is lost, a thief can disassemble the computer, in order to avoid automatic consumption of data, the thief can disassemble the computer, so as to obtain the data inside, and in order to avoid divulgence of the data in the computer, the scheme in the fourth embodiment is used for clearing the data, and the method comprises the following steps:

s40: the computer is removed and the sensor 16 signals a clear of the data.

The control chip 10, wireless module 12, hard disk 14, sensor 16 and power supply 18 are packaged within a computer. The sensor 16 senses that the computer is removed and sends a trigger signal to the control chip 10 to trigger the clearing of data.

S42: after receiving the trigger signal, the control chip 10 clears the data in the hard disk 14.

By the scheme in the fourth embodiment, the control chip 10 can obtain the command for clearing data, and clear the data in the hard disk 14, so that the data of the user is kept secret, and the disclosure of secret is prevented.

In the embodiment, the starting authorization of the user can be obtained after the computer is started, so that the confidentiality of computer data is improved; the data can also be cleared by whether the matching of the password is successful or by adopting the scheme in the third embodiment after the matching is unsuccessful, which is explained by the fifth embodiment, referring to fig. 5, and includes the following steps:

the wireless module 12 may send a message, such as a short message, a command for packet data, or a mail, to the network to alert the user whether to start the computer.

S502: the wireless module 12 judges whether a starting command of the user is received within a preset time, if so, S504 is executed, and the computer is started; if not, the method waits for triggering again and returns to the step S500.

S504: starting the computer and judging whether the password is input correctly; if yes, the computer is turned on in S506, and if not, the computer is turned on in S508 or S512.

S508: the control chip 10 sends a message of clearing data to the user through the wireless module 12.

The wireless module 12 may send a message to the user to clear the data by a short message, a command to group data, or a mail.

After receiving the information, the user can reply a command of whether to clear the data or not through a network terminal, such as a mobile phone, a computer connected with the internet and the like.

S510: the control chip 10 judges whether a command signal from a user is received through the wireless module 12 within a predetermined time; if so, S512 is performed, and if not, S514 is performed.

After S508, the wireless module 12 receives a message from the network, such as a short message, a command of packet data, or a mail, so as to obtain whether the user issues a command to clear data.

S512: the control chip 10 activates the hard disk 14 and performs an operation of erasing data.

Preferably, when the other users permitted by the user use the computer, the user may input wrong passwords, and the user may also choose to reply to a command of forcing to enter the system and the like so as to remotely assist the other users to use the computer.

S514: the control chip 10 computer is shut down.

In the embodiment, the computer is powered on to start up after obtaining the start authorization of the user, so that the data confidentiality of the computer is improved; data clearing can be carried out according to whether the matching of the passwords is successful; or after the matching is unsuccessful and the command of the user is obtained, the data is cleared. Therefore, the data confidentiality of the user is improved, the data of the user is kept in a confidential state, and the disclosure is prevented.
