Problems solved by technology

[0003] With the continuous development of mobile terminal technology, some new technologies are constantly being applied to mobile terminals. For example, in order to make mobile phones lighter and thinner, the concept of virtual SIM card or embedded SIM card is proposed. The module that realizes the function of the real SIM card does not need to install a physical SIM card on the mobile phone and design a physical card slot. The latter directly welds the SIM card chip in the mobile phone and cannot be replaced at will
After the mobile phone is stolen, the thief needs to change the SIM card to reuse the mobile phone, and there is also the risk of SIM card information leakage

Abstract

The embodiment relates the technology field of mobile communication in particular to an SIM card information protection method and a device. The embodiment discloses the SIM card information protection method and the device, comprising: Receive the action instructions of identifying user's operation on the SIM card information; obtaining the biometric characteristics input by the identifying user. If the biometric characteristics of the user input are matched by the preset biological characteristics, the SIM card information is manipulated according to the operation instructions. In this way, the embodiment can effectively prevent the SIM card information from being changed and improve the security of SIM card information.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular, to a method and device for protecting SIM card information. Background technique [0002] In the field of wireless communication, the SIM card of a mobile phone generally has two functions. One is identification. When the mobile phone is connected to the network, it needs to execute commands such as authentication and encryption through the SIM. This is the most important function. The second is the role of storage, storing contact numbers, email addresses, short messages, etc. At present, traditional mobile phones generally have one SIM card slot, and some mobile phones have dual SIM card slots. Before making a call with a mobile phone, the SIM card of the relevant communication operator must be installed. Therefore, after the mobile phone is stolen, the thief can pull out the SIM card and copy it, and there is a risk of SIM card informa...
