Detailed Description

The technical solutions of the present application will be specifically described below by way of examples and with reference to the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

It should be noted that: in the examples of this application, "first," "second," etc. are used to distinguish similar objects and not necessarily to describe a particular order or precedence.

In addition, the embodiments described in the present application may be arbitrarily combined without any collision.

Before describing the identification method in the embodiment of the present application, a method for locking a card by a terminal in the related art is described, and the method may be implemented by the following manner:

in the case that a subscriber identity module card (Subscriber Identity Module, SIM) card is inserted into the terminal, the user triggers a power-on key of the terminal, the terminal generates a power-on instruction based on the triggering of the power-on key by the user, and performs a power-on process based on the power-on instruction, for example, powers on a processor of the terminal, powers on the subscriber identity module card, and then the subscriber identity module card sends information capable of identifying the subscriber identity module card to the terminal, the information may be at least one of: international mobile subscriber identity (International Mobile Subscriber Identity, IMSI), integrated circuit card identity (Integrate circuit card identity, ICCID), mobile country code (Mobile Country Code, MCC), mobile network code (Mobile Network Code, MNC), mobile phone number.

The terminal may determine whether at least one of IMSI, ICCID, MCC, MNC and the mobile phone number is the same as at least one of IMSI, ICCID, MCC, MNC and the mobile phone number stored in the terminal, for example, the subscriber identity module card may send MCC and MNC to the terminal, the terminal determines whether MCC and MNC sent by the subscriber identity module card are the same as MCC and MNC stored in the terminal, and in the same case, the terminal may determine that the subscriber identity module card is successfully identified, so that the terminal may continue to perform the power-on operation, and in a different case, the terminal may determine that the subscriber identity module card is failed to identify, so that the terminal prohibits the power-on operation from being performed.

However, in the related art, the behavior of the subscriber identity module card is identified by the terminal, that is, only the behavior of the terminal side is limited, in many cases, if the terminal of the user is lost, but if the subscriber identity module card in the lost terminal is inserted into the new terminal, the new terminal does not normalize the behavior of the terminal side, so that the new terminal does not perform the step of judging whether the MCC and the MNC transmitted by the subscriber identity module card are the same as the MCC and the MNC stored in the new terminal, so that the new terminal can still normally use the subscriber identity module card in the lost terminal, that is, the purpose of protecting the information security of the user is still not achieved.

For example, the terminal of brand a has an identification function for a customer identification module card, but the terminal of brand B does not have an identification function for a customer identification module card, and if the terminal of brand a is lost, the customer identification module card in the terminal of brand a is inserted into the terminal of brand B, and the terminal of brand B can still normally use the customer identification module card.

In addition, even if the B-brand terminal has an identification function for the customer identification module card, if the step of identifying is by judging whether the MCC and MNC transmitted by the customer identification module card are identical to the MCC and MNC stored in the terminal, the B-brand terminal can still normally use the customer identification module card in the a-brand terminal as long as the MCC and MNC stored in the B-brand terminal are identical to the MCC and MNC transmitted by the customer identification module card.

Based on the problems existing in the related art, an embodiment of the present application provides an identification method, and fig. 1 is a schematic flow chart of the identification method provided in the embodiment of the present application, as shown in fig. 1, where the method is applied to a terminal, and the method includes:
