     It should be understood that, although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited by these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, first information may also be referred to as second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word “if” as used herein can be interpreted as “upon” or “when” or “in response to determining.” 
     An information acquisition method provided by some embodiments of the present disclosure can be introduced from a terminal side. 
     The information acquisition method provided by the embodiment of the present disclosure may be applied to a terminal, such as smart phones, tablet computers, personal digital assistants (PDAs), and the like.  FIG. 1  shows an information acquisition method according to some embodiments. As shown in  FIG. 1 , the information acquisition method includes the following steps. 
     In step  101 , when an application programming interface (API) is called by a target application (App) to acquire privacy information of a terminal, privacy-related information is determined according to instrumentation information in the API, wherein the privacy-related information is associated with a process of the target App acquiring the privacy information. 
     In some embodiments of the present disclosure, the target App may be any 
     App pre-installed on the terminal. The called API may be an API on which private information instrumentation is performed in advance. 
     The instrumentation refers to inserting some probes into a program on the basis of ensuring original logic integrity of the program. In some embodiments of the present disclosure, that private information instrumentation is performed on the API refers to inserting the probe that can correspond to the privacy information of the terminal into the API. Once the target App calls the API to acquire the privacy information of the terminal, what privacy information the target App has acquired from the terminal can be determined according to the instrumentation. 
     The private information of the terminal may include but is not limited to at least one of international mobile equipment identity (IMEI) information of the terminal, system identification information of the terminal, and a mobile phone number of the terminal. The system identification information of the terminal may be the identification information of Android, Apple and other systems adopted by the terminal. 
     In some embodiments of the present disclosure, the information associated with the process of that the target App calls the API on which the privacy information instrumentation is performed in advance to acquire the privacy information of the terminal can be used as the privacy-related information, including but not limited to at least one of process and thread information, context information, and log information. 
     In step  102 , the privacy-related information is stored. 
     In some embodiments of the present disclosure, the terminal may store all the privacy-related information in the process of that the target App calls the API to acquire the privacy information of the terminal, which facilitates the privacy-related information to be read and uploaded to the server side by the designated App subsequently. 
     In step  103 , the privacy-related information stored in a preset time period is read by a designated App, and the read privacy-related information is uploaded to a server side by the designated App. 
     In some embodiments of the present disclosure, the designated App may be an App associated with privacy protection on the terminal, such as a security center App. The preset time period may be a preset period length. All the privacy-related information stored in the terminal within the preset time period may be read and uploaded to the server side by the designated App. The server side may be a server, and can determine whether the process of the target App acquiring the privacy information of the terminal complies with a preset user privacy protection rule. 
     In the above embodiment, when the API is called by the target App to acquire the privacy information of the terminal, the privacy-related information associated with such process may be determined according to the instrumentation information in the API. Then the privacy-related information is stored. After that, the privacy-related information stored in the preset time period may be read by the designated App, and the read privacy-related information is uploaded to the server by the designated App. Subsequently, the server determines, according to the privacy-related information, whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule. The present disclosure can detect whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, thereby protecting personal privacy of a terminal user and improving network security. 
       FIG. 2  is another information acquisition method shown on the basis of the foregoing embodiment shown in  FIG. 1 . In some other embodiments, as shown in  FIG. 2 , the method may further include step  100  before the step  101 . 
     In step  100 , instrumentation is performed, by a read-only memory (ROM), on a plurality of APIs being called to acquire the privacy information in a framework layer for each piece of private information. 
     In some embodiments, this step only needs to be executed once for one terminal. When the step is being executed, the instrumentation is performed, by a program in the ROM of the terminal, on the plurality of APIs being called to acquire the privacy information in the framework layer for each piece of private information. 
     For example, the number of pieces of privacy information is three, and the number of the plurality of APIs is n, and then the n APIs include three instrumentations corresponding to different pieces of privacy information respectively. 
     In the above embodiments, the instrumentation may be performed in advance, by the ROM of the terminal, on the plurality of the APIs being called to acquire the privacy information in the framework layer, and may be performed for each piece of the private information. Subsequently, the privacy-related information is determined directly according to the instrumentation information in the API, which is easy to be implemented and has high availability. 
     In some other embodiments, for the above step  102 , the API in the designated App may be called to store the privacy-related information to a designated directory. 
     In some embodiments of the present disclosure, the designated App may be a security center App. Since storage space occupied by the privacy-related information is relatively large, the designated directory may be a directory preset on a secure digital memory (SD) card for storing the privacy-related information. 
     In the above embodiments, since the storage space occupied by the privacy-related information is relatively large, the directory preset on the secure digital memory card for storing the privacy-related information can be used as the designated directory, thereby storing the privacy-related information to ensure that the complete privacy-related information can be stored. 
     In some other embodiments, the above step  104  may include: 
     reading, by a target process of the designated App, the privacy-related information stored in the preset time period, and uploading, by the target process, the privacy-related information read to the server side. 
     In some embodiments of the present disclosure, the target process is a process of the designated App which is online at any time. 
     In the above embodiments, the target process in the designated App can be used to perform the reading of the privacy-related information and uploading of the same to the server side. The target process is the process of the designated App which is online at any time. Since the target process is online all the time, there is no need to start a separate process to read and upload the privacy-related information, thereby saving process resources. 
     An information acquisition method provided by an embodiment of the present disclosure will be introduced below from a server side. 
     The information acquisition method provided by the embodiment of the present disclosure may be applied to the server side, such as a server.  FIG. 3  is another information acquisition method according to some embodiments, and as shown in  FIG. 3 , the method includes the following steps. 
     In step  201 , privacy-related information uploaded by a terminal is received. 
     The privacy-related information is information associated with a process of a target application (App) acquiring privacy information of the terminal, and may include but is not limited to at least one of process and thread information, context information and log information which are associated with the process of the target App acquiring the privacy information of the terminal. 
     In step  202 , a target detection result is determined according to the privacy-related information. 
     The target detection result is configured to indicate whether the process of the target App acquiring the privacy information of the terminal complies with a preset user privacy protection rule. The preset user privacy protection rule may be the privacy information of the terminal allowed to be called by the App. 
     For example, App1 is allowed to call IMEI information of the terminal, and App2 is allowed to call the IMEI information and mobile phone number of the terminal. 
     In the above embodiment, after receiving the privacy-related information uploaded by the terminal, the server may determine, according to the privacy-related information, the target detection result indicating whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule. It achieves the purpose of detecting whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, so that the personal privacy of the terminal user can be protected and the network security can be improved. 
       FIG. 4  shows another information acquisition method based on the foregoing embodiments illustrated in  FIG. 3 . In some other embodiments, as shown in  FIG. 4 , the step  202  can include the following steps. 
     In step  202 - 1 , App identification information of the target App and first privacy information of the terminal acquired by the target App are determined according to the privacy-related information. 
     In this step, the server side acquires the privacy-related information, and thus can analyze the privacy-related information to acquire the App identification information of the target App and the first privacy information acquired by the target App during the process of acquiring the privacy information of the terminal. 
     In step  202 - 2 , second privacy information corresponding to the App identification information of the target App is determined according to a correspondence between preset App identification information and privacy information allowed to be acquired when the App is called. 
     In this step, the server side may pre-store the correspondence, so that the server side can determine the corresponding second privacy information according to the correspondence after determining the App identification information of the target App. 
     In step  202 - 3 , if the second privacy information includes the first privacy information, it is determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, and otherwise it is determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal does not comply with the preset user privacy protection rule. 
     For example, if the second privacy information is the IMEI information, and the first privacy information is also the IMEI information, it may be determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule. 
     In another example, if the second privacy information includes the IMEI information and the system identification information, and the first privacy information is the IMEI information and the system identification information, it is determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal does not comply with the preset user privacy protection rule. 
     In the above embodiments, If the first privacy information is included in the second privacy information, it is determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, and otherwise it is determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal does not comply with the preset user privacy protection rule, which is easy to be implemented and has high availability. 
       FIG. 5  shows another information acquisition method based on the foregoing embodiment in  FIG. 3 . In some other embodiments, as shown in  FIG. 5 , the method may further include step  203 . 
     In step  203 , the target detection result is uploaded to the detection platform. 
     The server side can also upload the target detection result to the detection platform. The target detection result is output or displayed by the detection platform, so that the terminal privacy protection analysis can be better performed. 
       FIG. 6  shows another information acquisition method according to some embodiments. In some other embodiments, as shown in  FIG. 6 , the method includes the following steps. 
     In step  300 , the terminal performs, by a read-only memory (ROM), instrumentation on a plurality of APIs being called to acquire privacy information in a framework layer for each piece of private information. 
     This step only needs to be performed once. After the private information instrumentation is finished, it can be directly executed from step  301  subsequently. 
     In step  301 , the terminal determines privacy-related information associated with a process of a target application (App) acquiring the privacy information according to instrumentation information in the API, when calling, by the target App, the API to acquire the privacy information of the terminal. 
     The target App may be any App on the terminal. The API may be an API on which the private information instrumentation is performed in advance. 
     The privacy information includes at least one of international mobile equipment identity (IMEI) information of the terminal, system identification information of the terminal, and a mobile phone number of the terminal. 
     The privacy-related information includes at least one of process and thread information, context information, and log information. 
     In step  302 , the terminal calls the API in the designated App to store the privacy-related information to a designated directory. 
     The designated App may be a security center App, and the designated directory may be a directory preset on a secure digital memory card for storing the privacy-related information. 
     In step  303 , the terminal reads, by a target process of the designated App, the privacy-related information stored in the designated directory in a preset time period, and uploads, by the target process, the read privacy-related information to the server side. 
     The target process is a process of the designated App which is online at any time. 
     In step  304 , the server side determines App identification information of the target App and first privacy information of the terminal acquired by the target App according to the privacy-related information. 
     In step  305 , the server side determines second privacy information corresponding to the App identification information of the target App according to a correspondence between preset App identification information and privacy information allowed to be acquired when the App is called. 
     In step  306 , if the second privacy information includes the first privacy information, the server side determines that the target detection result is that the process of the target App acquiring the privacy information of the terminal complies with a preset user privacy protection rule, and otherwise the server side determines that the target detection result is that the process of the target App acquiring the privacy information of the terminal does not comply with the preset user privacy protection rule. 
     In step  307 , the server side uploads the target detection result to a detection platform. 
     In the above embodiment, it can detect whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, thereby protecting personal privacy of a terminal user and improving network security.

     Various embodiments of the present disclosure can have one or more of the following advantages. 
     Upon that the API is called by the target App to acquire the privacy information of the terminal, the privacy-related information associated with such process may be determined according to the instrumentation information in the API. Then the privacy-related information is stored. After that, the privacy-related information stored in the preset time period may be read by the designated App, and the read privacy-related information is uploaded to the server side by the designated App. Subsequently, the server side determines, according to the privacy-related information, whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule. Various embodiments of the present disclosure can detect whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, thereby protecting personal privacy of a terminal user and improving network security. 
     The instrumentation can be performed in advance, by the ROM of the terminal, on the plurality of the APIs being called to acquire the privacy information in the framework layer, and may be performed for each piece of the private information. Subsequently, the privacy-related information is determined directly according to the instrumentation information in the API, which is easy to be implemented and has high availability. 
     The privacy-related information includes, but is not limited to, at least one of the process and thread information, the context information and the log information, which are associated with the process of the target App acquiring the privacy information of the terminal. It is convenient for the server side to determine subsequently, according to the privacy-related information, the detection result of indicating whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, which can have a high availability. 
     The API in the designated App can be called to store the privacy-related information to the designated directory, and then the privacy-related information stored in the designated directory in the preset time period can be read by the designated App, which is easy to be implemented and has high availability. 
     As storage space occupied by the privacy-related information is relatively large, the directory preset on the secure digital memory card for storing the privacy-related information can be used as the designated directory, thereby storing the privacy-related information to ensure that the complete privacy-related information can be stored. 
     The target process in the designated App can be used to perform the reading of the privacy-related information and uploading of the same to the server side. The target process is a process of the designated App which is online at any time. Since the target process is online all the time, there is no need to start a separate process to read and upload the privacy-related information, thereby saving process resources. 
     After receiving the privacy-related information uploaded by the terminal, the server side can determine, according to the privacy-related information, the target detection result indicating whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule. It achieves the purpose of detecting whether the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, so that the personal privacy of the terminal user can be protected and the network security can be improved. 
     The server side can determine the App identification information of the target App and the first privacy information of the terminal acquired by the target App according to the privacy-related information. The second privacy information corresponding to the target App can be determined according to the correspondence between the preset App identification information and the privacy information allowed to be acquired when the App is called. If the first privacy information is included in the second privacy information, it is determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal complies with the preset user privacy protection rule, and otherwise it is determined that the target detection result is that the process of the target App acquiring the privacy information of the terminal does not comply with the preset user privacy protection rule, which is easy to be implemented and has high availability. 
     The server side can also upload the target detection result to the detection platform. The detection platform outputs or displays the same, so that the terminal privacy protection analysis can be better performed.

     While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any claims, but rather as descriptions of features specific to particular implementations. Certain features that are described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination. 
     Moreover, although features can be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination can be directed to a subcombination or variation of a subcombination. 
     Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results.

Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products. 
     As such, particular implementations of the subject matter have been described. 
     Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking or parallel processing can be utilized. 
     It is intended that the specification and embodiments be considered as examples only. Other embodiments of the disclosure will be apparent to those skilled in the art in view of the specification and drawings of the present disclosure.

     It should be understood that “a plurality” or “multiple” as referred to herein means two or more. “And/or,” describing the association relationship of the associated objects, indicates that there may be three relationships, for example, A and/or B may indicate that there are three cases where A exists separately, A and B exist at the same time, and B exists separately. The character “/” generally indicates that the contextual objects are in an “or” relationship. 
     In the present disclosure, it is to be understood that the terms “lower,” “upper,” “under” or “beneath” or “underneath,” “above,” “front,” “back,” “left,” “right,” “top,” “bottom,” “inner,” “outer,” “horizontal,” “vertical,” and other orientation or positional relationships are based on example orientations illustrated in the drawings, and are merely for the convenience of the description of some embodiments, rather than indicating or implying the device or component being constructed and operated in a particular orientation. Therefore, these terms are not to be construed as limiting the scope of the present disclosure. 
     Moreover, the terms “first” and “second” are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated.
