Description
Technical Field
The present invention relates to the field of data service technologies, and in particular, to a Subscriber Identity Module (SIM) card access control method, apparatus, medium, and device.
Background
The SIM card is an important asset of the user, and is associated with the user's mobile phone number, which is a main authentication means for user accounts of various applications, such as a user account of a financial payment type application, and a user account of an internet application. In the authentication process of various user accounts, the advanced authentication of the user account is generally performed through the mobile phone number registered by the user, that is, the mobile phone number can be used as an ultimate means for authenticating the identity of the user. In this case, if the SIM card is lost (e.g., the mobile phone is lost), a malicious finder may log in a user account of a financial payment application of the user using the SIM card and perform various operations, resulting in a fund loss of the owner; or log in to the user's user accounts for various internet applications, resulting in a loss of privacy. In summary, if the SIM card is lost, there is a great risk that the user account security will be lost, which may cause serious loss.
The loss of the SIM card, which causes a great risk, has become a common consensus in the mobile communication industry at present. The following measures currently exist to prevent the risk of loss of the SIM card:
1. the operator provides a quick loss reporting way, the user can immediately dial the service telephone of the operator for loss reporting after finding that the SIM card is lost, and the original SIM card fails to work after loss reporting, so that loss caused by loss of the SIM card is avoided.
2. The SIM card itself has a Personal Identification Number (PIN) for protecting the SIM card. Before use, the SIM card can work normally only by inputting the PIN code. If the malicious finder does not know the PIN code corresponding to the SIM card, the SIM card cannot be used.
However, with the first measure, if the user is not reported timely enough, the SIM card may still be used by others before reporting the loss, which still results in loss.
For the second measure, if the user forgets the PIN code, the service password needs to be used to dial the customer service hot line of the operator, after the user data is checked, the customer service can inform the initial PIN Unlocking Key (PUK) code, and the PIN code can be unlocked by inputting the PUK code. If the number of times of inputting the PUK code by mistake is too large, the SIM card can be locked permanently. Therefore, the PIN code is complex to use, and the user experience is poor. Therefore, at present, the PIN code is basically in a closed state, and is rarely used by a user really.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of the present invention and the above-described drawings, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
An embodiment of the present invention provides a SIM card access control method, where the flow of the steps of the method may be as shown in fig. 1, and the method includes:
step 101, monitoring a screen unlocking event of the mobile terminal.
In this step, the screen unlock event in the mobile terminal may be monitored. If it is determined that the screen unlock is successful, execution may continue to step 102. If the screen unlocking is determined to fail, the SIM card unlocking step does not need to be executed. For example, after the mobile phone is started, a password for unlocking the screen is input in the screen locking interface, if the password for unlocking the screen is input incorrectly, the screen is considered to be unlocked unsuccessfully, and the step of unlocking the SIM card is not required to be executed.
And 102, unlocking the SIM card.
By monitoring the screen unlocking event of the mobile terminal, if the screen is determined to be successfully unlocked, the SIM card can be unlocked by using the password of the unlocking screen due to the fact that the password of the unlocking SIM card has a mapping relation with the password of the unlocking screen.
The mapping relation exists between the password for unlocking the SIM card and the password for unlocking the screen, and the password for unlocking the screen can be understood as the same as the password for unlocking the SIM card. The SIM card is unlocked by the password for unlocking the screen, which can be understood as unlocking the SIM card by directly using the password for unlocking the screen as the password for unlocking the SIM card.
Preferably, a mapping relation exists between the password for unlocking the SIM card and the password for unlocking the screen, the password for unlocking the SIM card can be generated by the password for unlocking the screen, and the password for unlocking the SIM card can be different from the password for unlocking the screen, so that the safety of the SIM card is further improved. Specifically, unlocking the SIM card by using the password for unlocking the screen may include: and generating a password for unlocking the SIM card by using the password for unlocking the screen, and unlocking the SIM card by using the generated password for unlocking the SIM card.
Preferably, after the SIM card is successfully unlocked, the state of the SIM card can be switched to the locked state only when the mobile terminal is powered off, so that after the SIM card is successfully unlocked, the SIM card unlocking operation does not need to be executed for many times in the powered-on state of the mobile terminal. And under the condition that the mobile terminal is started up and normally operates, the SIM card is in an unlocking state, and the condition that malicious applications are used as PIN attempts to lock the card can be avoided. That is, in this embodiment, if it is determined that the SIM card is successfully unlocked, the SIM card may be kept in the unlocked state until the mobile terminal is powered off, and the SIM card is set in the locked state.
After the SIM card is successfully unlocked, when the mobile terminal is in a power-on state, under some specific conditions, such as the SIM card is restarted (reset), if the SIM card is changed from the unlocked state to the locked state, the SIM card can be kept in the unlocked state through a cache mechanism of a password for unlocking the SIM card.
Specifically, after the password for unlocking the SIM card is generated by using the password for unlocking the screen, the password for unlocking the SIM card may be further cached. And when the SIM card is determined to be in the locked state, the SIM card can be unlocked by utilizing the cached password for unlocking the SIM card. For example, when the mobile terminal is in a power-on state and an application needs to access the SIM card, if the SIM card is determined to be in a locked state, the cached password for unlocking the SIM card may be used to unlock the SIM card.
Of course, after the SIM card is successfully unlocked, a specific Application Programming Interface (API) may be provided to the application that needs to access the SIM card, so that the application can access the SIM card.
It should be noted that, before step 101, the present embodiment further includes a process of setting a password of the SIM card and setting a password for unlocking the screen. The process is illustrated in four cases:
in the first case: the mobile terminal has not set the password for unlocking the screen, and the SIM card in the mobile terminal has not set the password for unlocking the SIM card. This situation may be understood as a combination of an unused mobile terminal and an unused SIM card.
In this case, the password for unlocking the screen may be directly set by the user, and the password for unlocking the SIM card may be automatically set using the set password for unlocking the screen.
Specifically, the set password for unlocking the screen may be determined, and the password for unlocking the SIM card may be set according to the set password for unlocking the screen.
In the second case: the mobile terminal sets the password for unlocking the screen, and the SIM card in the mobile terminal does not set the password for unlocking the SIM card. This case may be understood as a combination of a used mobile terminal and an unused SIM card.
In this case, since the password for unlocking the screen has already been set, the password for unlocking the SIM card can be automatically set using the set password for unlocking the screen. Specifically, the password for unlocking the SIM card may be automatically set according to the password for unlocking the screen input by the user.
Specifically, the input password for unlocking the screen can be received, and the password for unlocking the SIM card can be set by using the input password for unlocking the screen after the screen is successfully unlocked.
In the third case: the mobile terminal does not set the password for unlocking the screen, and the SIM card in the mobile terminal sets the password for unlocking the SIM card. This case may be understood as a combination of an unused mobile terminal and a SIM card used on the other mobile terminal (it may be understood that the set password for unlocking the SIM card is generated from the password for unlocking the screen set on the other mobile terminal, or is the same as the password for unlocking the screen set on the other mobile terminal).
In this case, since the password to unlock the SIM card has already been set, the SIM card is in an access-protected state. In order to access the SIM card, a password for unlocking the screen needs to be set according to the set password for unlocking the SIM card.
Specifically, the set password for unlocking the screen can be determined, and the set password for unlocking the screen is set according to the set password for unlocking the SIM card.
In this case, the security of the SIM card can be further effectively protected, so that even if a malicious finder obtains the SIM card and replaces the mobile terminal with an unused mobile terminal, the SIM card cannot be accessed because the set password for unlocking the SIM card is unknown. Further, if a malicious finder attempts to unlock the SIM card by inputting a password for unlocking the screen, in this embodiment, if the number of times of failure to unlock the SIM card exceeds the set number of times, the SIM card may be locked.
In a fourth case: the mobile terminal sets a password for unlocking the screen, and the SIM card in the mobile terminal also sets a password for unlocking the SIM card. This case may be understood as a combination of a used mobile terminal and a SIM card used on other mobile terminals.
In this case, since the password to unlock the SIM card has already been set, the SIM card is in an access-protected state. The password of the unlocking screen set by the mobile terminal is not matched with the password of the unlocking SIM card set by the SIM card, and the access to the SIM card can not be realized through the password of the unlocking screen set by the mobile terminal. In order to access the SIM card, the set password for unlocking the screen needs to be changed according to the set password for unlocking the SIM card.
Specifically, a change to the set password for unlocking the screen may be determined, and the change is determined according to the set password for unlocking the SIM card.
In this case, it is also possible to further prevent a malicious finder from accessing the SIM card by replacing the mobile terminal after obtaining the SIM card.
It should be noted that, due to the similarity between the embedded SIM card (eSIM card) and the secure media such as the secure module (SE), the present solution is also applicable to access control on the secure media such as the eSIM card or the SE, and the detailed description is omitted in this embodiment.
Based on the same inventive concept as the first embodiment, the following apparatuses are provided.

The SIM access proxy module 12 is further configured to provide a specified API to an application that needs to access the SIM card, for the application to access the SIM card. Specifically, when the other service module 13 accesses the SIM card through the SIM access agent module 12, the service on the SIM card can be accessed through the specified API provided by the SIM access agent module 12, and the SIM card unlocking operation does not need to be executed again in the process.
