Abstract: The present invention provides a mobile terminal anti-theft method (100) which comprises triggering mobile terminal anti-theft operations according to operations on a mobile terminal (S110). The mobile terminal anti-theft operations at least comprise: collecting location information and environment information of the mobile terminal (S122, S124) and backing up private data of the mobile terminal (S126) and sending the collected location information and environment information and the backup private data to a result designated location (S130). The present disclosure further provides a mobile terminal (200) for achieving the mobile terminal anti-theft method (100).

Abstract: A display method that is used for a security device installed with a camera module and a display module includes A. when the security device captured a preset image by the camera module, the security device displaying an interface for entering a password by the display module, and B. when the password is successfully matched, the security device displaying a predetermined object by the display module. By hiding the interface for entering a password, the invention improves the security capability of the device and meets the requirement of information security at present.

Abstract: Provided is a display method for a security device installed with a photographing module and a display module. The method comprises: A. when the security device captures a specific image via the photographing module, the security device displays a password input interface via the display module; and B. when password matching is successful, the security device displays a predetermined object via the display module. The present invention improves security performance of a device by concealing the password input interface, and satisfies the current requirement for information security.

Abstract: The present disclosure is directed to a method for sending and receiving an encrypted message and a system thereof. The method includes steps of encrypting a message, transforming the encrypted message into network address, sending the network address to a receiver, and accessing a server according to the network address by the receiver, and a server decrypting the message, presenting the decrypted message to the receiver, and thereafter preventing the message from being accessed. Advantages include that any mobile phone capable of connection to a wireless network can read an encrypted message without installation of a decryption software on a mobile phone of a receiver.
