Abstract: A mobile terminal and an anti-theft method thereof are described. The anti-theft recognition module of the mobile terminal sends a security number acquisition instruction to a security number acquisition module after determining that the mobile terminal enters an anti-theft mode, the security number acquisition module automatically acquires a security number according to the security number acquisition instruction and sends the acquired security number to an anti-theft processing module, the anti-theft processing module gives an alarm according to the received security number to help the owner of the mobile terminal retrieve the mobile terminal or the information stored in the mobile terminal, thereby minimizing the loss of the owner of the mobile terminal and eliminating the potential safety hazard brought by the loss of the personal information stored in the mobile terminal.

Abstract: The disclosure discloses a method, an apparatus, a terminal and a system for channel encryption. The method includes that: a relay server receives a channel encryption request from a client, and acquires encrypted information, client information and a locally stored channel Extensible Markup Language (XML) file of the client from the channel encryption request (S101); and according to the encrypted information, the client information and the locally stored channel XML file of the client, the relay server acquires an encrypted channel XML file and stores the encrypted channel XML file, and sends the encrypted channel XML file to the client to enable the client to update the locally stored channel XML file according to the encrypted channel XML file (S102). By means of the technical solution of the disclosure, the privacy of a user is protected, and the security of Really Simple Syndication (RSS) channel management is enhanced.
