Data information transmission device and method applied to mobile terminal

Abstract

The invention discloses a data information transmission device and a data information transmission method applied to a mobile terminal. The data information transmission device comprises an activation module and a secure transmission module, wherein the activation module is used for identifying data information to be controlled from the data information currently to be transmitted by a network application program installed on the mobile terminal, and enabling the secure transmission module, or determining the data information specified by a user according to a user operation, and enabling the secure transmission module; and the secure transmission module is used for transmitting the data information to be controlled or specified by the user by a virtual private network (VPN) channel. When the mobile terminal accesses the Internet, the data information to be encrypted and protected is transmitted by the virtual private network (VPN) channel according to settings or user triggering, so the security of the data information is ensured.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data information transmission device and method applied to a mobile terminal. Background technique [0002] Nowadays, more and more people use mobile terminals to access the Internet. When users are using it, it is inevitable that they will send some information to the peer end of the Internet through the network application installed in the mobile terminal, including: information that requires a high level of security and information that the user considers to involve personal privacy. When sending these information, the mobile terminal The web applications installed in will not transmit this information separately from general information. [0003] For information with different security requirements, the general information security standards are uniformly used for transmission, which is undoubtedly extremely unfavorable for the user's information security. Especially w...

Problems solved by technology

[0003] For information with different security requirements, the general information security standards are uniformly used for transmission, which is undoubtedly extremely detrimental to the user's information security.

Especially when the information with high security requirements involves the personal privacy of users, the transmission of these information with lower security standards increases the possibility of information being stolen or peeped. Once the information is leaked, it is likely to be Bring a lot of inconvenience and property loss to users, and even personal reputation is violated

[0004] Therefore, when a mobile terminal accesses the Internet, it is impossible to distinguish and transmit information with special security requirements and ordinary data information through their respective network channels, resulting in information insecurity, which has become an urgent technical problem to be solved.
