Problems solved by technology
This practice not only violates the interests of the majority of users, but also violates the interests of operators and mobile terminal manufacturers, and damages the image of mobile terminal manufacturers
In addition, when a communication operator provides communication services, if two mobile terminals with the same IMEI are detected in the same cell, one of the mobile terminals may not be able to access the communication network, which will affect the normal communication of users.

The embodiment of the invention discloses an information tampering prevention method and device, a server and a terminal. The method comprises the following steps: when a write information request of an information modification tool having a permission for built-in information is detected and a modification operation for the built-in information needs to be authorized, generating a random key; encrypting the random key and to-be-written information by employing a preset public key to obtain first encrypted data, and transmitting the first encrypted data to the server via the information modification tool, so that the server generates second encrypted data according to the first encrypted data; and acquiring the second encrypted data, decrypting the second encrypted data by employing the random key to obtain the to-be-written information, and modifying the built-in information according to the to-be-written information. According to the technical scheme provided by the embodiment of the invention, the effect of preventing the built-in information of the terminal from being tampered maliciously is achieved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of information security, and in particular, to an information tamper-proof method, device, server and terminal. Background technique [0002] Terminals are often built with some key information before they leave the factory. Some of these key information are used to assist the terminal to perform basic functions, and some are used as the terminal's identity. For example, the IMEI (International MobileEquipment Identity, mobile equipment international identity code) of the mobile terminal, which is like the identity card of the mobile terminal, is used to uniquely identify the mobile terminal. [0003] However, with the development of technology, there are some methods for unauthorized tampering with the built-in information of the terminal, and tools for executing such methods. Through the method of unauthorized tampering with the built-in information of the terminal, the setting b...
