In order to prevent personal information of a user from being stolen by an illegal APP, the prior art generally limits the authority of the APP, such as limiting the APP not to send short messages, limiting the APP not to read contact information, limiting the APP not to read a phone number of a local computer, and the like. However, for part of the APP, if the rights are limited, part of the functions of the APP, even all of the functions, cannot be used. For example, some APPs providing internet phone service cannot complete the corresponding phone function without granting the APP with the right to make a phone call and the right to read a contact; for another example, some games APP requiring real-name registration may not identify the identity of the current game user if the APP is not granted with the right to read a phone number, and may not complete account registration, and a user may be considered as a non-identical account when removing login data or uninstalling a reinstallation or using another terminal to log in, so that the user may not log in normally. Therefore, the technical problem that the APP function is normal and the SIM card information safety cannot be considered simultaneously exists in the prior art.
In order to solve the technical defects in the prior art, embodiments of the present invention provide a method and an apparatus for protecting information security of a SIM card, when detecting that an APP in a blacklist obtains parameter information of a SIM card of an electronic device, a false value is returned to the APP to replace the parameter information of the SIM card that should be returned originally, so as to achieve a technical effect of not affecting a normal use function of the APP on the premise of ensuring information security of the SIM card.
Referring to fig. 1, a method for protecting SIM card information provided by the embodiment of the present invention mainly includes the following steps:
step 101: and receiving a data request initiated by the APP, wherein the data request is used for acquiring parameter information of a SIM card of the electronic equipment.
The parameter information of the SIM card may be one or more of a phone number, an Integrated Circuit Card Identification (ICCID), a short message, contact information, an operator name, a country code, and a mobile network code, which is not limited in the embodiments of the present invention.
The obtaining of the parameter information of the SIM card of the electronic device may include, but is not limited to, the following three ways: 1) directly calling a communication interface to read the parameter information stored on the SIM card; 2) reading parameter information of an SIM card locally stored in the electronic equipment; 3) and sending a query short message to an operator registered by the SIM card, and acquiring the parameter information of the SIM card from the operator.
Correspondingly, when the method 1) is adopted to obtain the parameter information of the SIM card of the electronic device, the data request may include a query identifier, where the query identifier is used to indicate that the parameter information is obtained from the SIM card; when the method 2) is adopted to obtain the parameter information of the SIM card of the electronic device, the data request may include a query identifier, where the query identifier is used to indicate that the parameter information is locally obtained from the electronic device; when the method 3) is adopted to obtain the parameter information of the SIM card of the electronic equipment, the data request comprises a request for sending a query short message to an operator registered by the SIM card, and the query short message at least comprises the address of the operator registered by the SIM card.
Step 102: and if the APP is in the blacklist, returning a false value to the APP.
In a specific implementation process, the false value may be a false value randomly generated by the electronic device for the APP, or a false value locally pre-stored in the electronic device.
When the dummy value is obtained by locally reading from the electronic device, a dummy database can be pre-established locally in the electronic device. Generally, when a new SIM card is inserted into the electronic device, a database is generated in the electronic device for storing parameter information of the newly inserted SIM card, and when the APP needs to acquire the parameter information of the SIM card, the APP generally reads the parameter information directly from the database. And when the APP in the blacklist requests to acquire the parameter information of the SIM card, the false value of the parameter in the false database is adopted to replace the parameter information of the real SIM card and is fed back to the APP.
It should be noted that the execution main body of each operation step may be an operating system of the electronic device, where the operating system may be implemented by executing an operating system instruction code by a general-purpose processor of the electronic device, or the execution main body of each operation step may be a separately arranged processing chip in the electronic device, where the processing chip implements each method step by executing a pre-stored instruction, and a specific implementation manner of the execution main body is not specifically limited in the embodiment of the present invention.
In the above scheme, when detecting that there is the APP in the blacklist to obtain the parameter information of the SIM card of the electronic equipment, return the false value to give this APP, replace the parameter information of this SIM card that should return originally, can maintain the information security of SIM card under the circumstances that does not hinder APP normal operating, reached and compromise the normal technological effect with SIM card information security of APP function simultaneously.
Optionally, in order to prevent the APP in the blacklist from reading parameter information from the SIM card by calling an interface for communicating with the SIM card, in addition to performing step 102 to return a false value to the APP, the method may further include: and forbidding the APP to call an interface for communicating with the SIM card. By the method, the safety of the SIM card information can be further improved.
Optionally, in order to prevent the APP in the blacklist from obtaining the parameter information by querying the operator, in addition to performing step 102 to return the false value to the APP, the method may further include: and forbidding to return the parameter information fed back by the operator to the APP. By the method, the information security of the SIM card can be further improved.
Optionally, if the APP is not in the blacklist, the data request may be directly responded, the parameter information of the SIM card may be returned to the APP, and it may also be further determined whether the APP is in the whitelist, and when the APP is in the whitelist, the parameter information of the SIM card may be returned to the APP.
In a specific implementation process, if a certain APP does not belong to either the blacklist or the whitelist, the type of the APP may be further queried for the user, and the APP is added to the whitelist or the blacklist according to a user instruction.
In a specific implementation process, the black list or the white list may be automatically generated by the electronic device or may be user-defined, and the embodiment of the present invention is not particularly limited.
When the black list or the white list is established in an automatic generation mode of the electronic device, the electronic device can classify all the APPs installed on the electronic device according to the types of the APPs. For example, financial APPs such as a pay bank APP, a stock APP, and the like, when a user needs to strictly identify the user identity during use, the user identity can be completely divided into a white list, and real parameter information is returned for any data request of the APP; for another example, the user often needs to authenticate the user identity when using the APP related to money transaction, such as WeChat and Paibao, and can also be completely divided into a white list, and any data request for the APP returns real parameter information; for another example, social software such as a people network and a QQ space can implement a mechanism that a part of data requests to return a false value, for example, when the people network requests to acquire contact information, the people network can be divided into a white list and return real contact information, which is convenient for recommending friends for a user, and when the people network requests to acquire a short message, the people network can be divided into a black list and return a false value, which prevents the personal privacy of the user from being revealed; for another example, some APP of malicious attack class, forcibly installed game plug-in, etc. may be fully classified into a blacklist, and any request for this type of APP returns a false value.
Through this mode, can establish the black and white list for APP on the electronic equipment, the user can set up the security demand of different grades and type to different APPs, guarantees SIM card information security, improves user experience.
