     TECHNICAL FIELD 
     The present invention relates to the field of communications technologies, and particularly to a data card, and a method and a system for identifying fingerprint with a data card. 
     BACKGROUND 
     A data card, also known as a wireless network card, a broadband network card, or a USB modem, is Internet access equipment for accessing a wireless network. The data card can access the wireless network through mobile communication technologies such as the Global System for Mobile communications (GSM), the Universal Mobile Telecommunication System (UMTS) or the Code Division Multiple Access (CDMA), so as to realize functions such as voice, short messages, and data services. The main function of the data card is to connect to the Internet through dial-up for data services (commonly known as accessing the Internet). 
     With the rapid development of the mobile communication technology, data services such as wireless Internet access are gradually becoming mature, and portable and small-size wireless Internet access terminals such as a wireless data card are becoming increasingly popular. The wireless data card does not need a power charger, and can be supplied by directly plugging into a universal serial bus (USB) port of a notebook computer or a desktop computer. With just one Subscriber Identity Module (SIM) card, a user can have data services such as wireless Internet access without a network cable, so as to enjoy the Internet anytime and anywhere. 
     The current wireless data card has security deficiencies. An SIM card has a few simple protective measures, namely, the user can set a simple combination of numbers from 0 to 9 as a personal identification number (PIN) code, and the SIM card can only be used after the PIN code is input. In this mode, the password is simple, and the user only needs to input numbers to access Internet by using the data card. 
     In the implementation of the present invention, the inventor finds that the prior art has the following problems. The requirements for setting the PIN code of the SIM card confined to numbers are simple, so that the PIN code can be easily cracked, resulting in low security. 
     SUMMARY OF THE INVENTION 
     An embodiment of the present invention, according to an aspect, provides a fingerprint identification data card, and according to another aspect, provides a method for identifying fingerprint with data card, improving the security of the use of the data card, and effectively ensuring that the data card is not misappropriated. 
     An embodiment of the present invention provides a data card, which includes a fingerprint collection module that is configured to collect user&#39;s fingerprint information by using a fingerprint scanner on the data card. A fingerprint authentication module is configured to compare the collected fingerprint information with a stored fingerprint template, and to output a comparison result. A control module is configured to control the data card according to the comparison result output by the fingerprint authentication module. 
     An embodiment of the present invention further provides wireless Internet access equipment, which includes a registration module that is configured to register the wireless Internet access equipment with the wireless network. A fingerprint identification module is configured to obtain fingerprint information input by the user by using a fingerprint sensor, and to match the input fingerprint information with a stored fingerprint template after the registration module finishes registration. A processing module is configured to perform a dial-up connection and to establish a data service connection between the wireless Internet access equipment and the wireless network when the input fingerprint information successfully matches with the stored fingerprint template in the fingerprint identification module. 
     An embodiment of the present invention further provides a method for identifying fingerprint with data card. A user&#39;s fingerprint information is collected by using a fingerprint scanner of the data card. The collected fingerprint information is compared with a stored fingerprint template and a comparison result is output. Corresponding control on the data card is performed according to the output comparison result. 
     Furthermore, an embodiment of the present invention further provides a dial-up method for accessing wireless Internet. Wireless Internet access equipment is registered with a wireless network. A fingerprint sensor is used to obtain fingerprint information input by the user. The input fingerprint information is matched with a stored fingerprint template. If the input fingerprint information successfully matches with the stored fingerprint template, the wireless Internet access equipment performs a dial-up connection, and a data service connection is established with the wireless network. 
     It can be known from the preceding technical solutions that, the user&#39;s fingerprint information is collected by using the fingerprint scanner on the data card and compared with the stored fingerprint template, the comparison result is output, and then the data card is controlled according to the output comparison result. Therefore, the use of the data card is controlled through the fingerprint authentication, and the data card can only be used after successful fingerprint matching. As the security of fingerprint authentication is much higher than the security of password authentication, the security of the data card is improved, and it is effectively ensured that the data card is not misappropriated.

     DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS 
     The technical solution under the present invention is elaborated below with reference to accompanying drawings. Evidently, the embodiments described below are for the exemplary purpose only, without covering all embodiments of the present invention. Those skilled in the art can derive other embodiments from the embodiments given herein without making any creative effort, and all such embodiments are covered in the protection scope of the present invention. 
     As shown in  FIG. 1 , an embodiment of the present invention provides a method for identifying fingerprint with a data card, which includes the following steps. 
     Step  71 : User&#39;s fingerprint information is collected by using a fingerprint scanner of the data card. 
     Step  72 : The collected fingerprint information is compared with a stored fingerprint template, so as to determine whether the collected fingerprint information matches with the fingerprint template, and then a comparison result is output. 
     Step  73 : The data card is controlled according to the output comparison result. 
     The data card establishes a wireless connection with the Internet through a radio frequency (RF) module to receive and transmit data. The data card is connected to a user terminal through various interfaces (such as a universal serial bus, USB interface), so that the user terminal can perform data transmission with the Internet through the data card. 
     The corresponding control in step  73  may include a number of steps. The user is authenticated through fingerprint authentication. If the collected fingerprint information matches with the fingerprint template, it is determined that the authentication is successful, and the user corresponding to the collected fingerprint information is allowed to access the Internet by using the data card. Otherwise, if the collected fingerprint information does not match with the fingerprint template, it is determined that the authentication is failed, and the user is not allowed to use the data card. And/or, one or more different fingerprint templates are stored, and each fingerprint template corresponds to different operations. If the collected fingerprint information matches with any one of the fingerprint templates, the operation corresponding to the matched fingerprint template is performed. If the collected fingerprint information matches with none of the fingerprint templates, the data card performs no operation or notifies the user that the fingerprint authentication is failed through the data card or the user terminal connected to the data card. As for the implementation that the user corresponding to the collected fingerprint information is allowed to access the Internet by using the data card, and the implementation of the operations corresponding to the matched fingerprint templates, the related content in the device embodiment can be referred to, which will not be described here again. 
     It should be noted that, for a multi-mode data card, the user can choose different Internet services by registering different fingerprint templates. For example, for a data card that supports both the Global System for Mobile Communications (GSM) and the Wideband Code Division Multiple Access (WCDMA), the user registers the left index finger to initiate the GSM network, and registers with the right index finger to initiate the WCDMA network. After inserting the data card, the user swipes the left index finger to initiate the RF module of the GSM, and at this time, the GSM network can be searched and registered. Similarly, the user swipes the right index finger to initiate the RF module of the WCDMA to use the WCDMA network. 
     In addition, after step  73 , the above method may further include step  74 . A notification is sent through the data card or the user terminal connected to the data card to notify the user of the fingerprint authentication result. Here, the user&#39;s fingerprint authentication result may be: the fingerprint authentication is successful; the fingerprint authentication is successful, and the data card has established a connection with the Internet; the fingerprint authentication is successful, and the data card has established a connection with the Internet through one of the multiple RF modules; the fingerprint authentication is failed, and the user cannot use the data card; the fingerprint authentication is failed, and the user is required to input the fingerprint information again. 
     In addition, before step  71 , the above method may further include step  70 . When the data card is set, a fingerprint template is collected by using the fingerprint scanner and stored in a storage module of the data card. The storage module may be a memory or a non-volatile memory such as a Flash. For example, when the user initiates the data card for the first time, the data card prompts the user to input each fingerprint template, and the fingerprint information input by using the fingerprint scanner is stored in the storage module as a fingerprint template. Alternatively, during the use of the data card, the original fingerprint template is updated and replaced, and the fingerprint information input by using the fingerprint scanner at this time is stored in the storage module to replace the original fingerprint template. Before the update and replacement, it can be set that the user needs to input the correct fingerprint information and the update and replacement is only allowed after the authentication of the fingerprint authentication is successful. 
     It should be noted that, if the data card has only one RF module, when the data card is powered on, the RF module immediately starts to search and register with the network, and the user is not allowed to use the data card. Next, after the fingerprint authentication is successful (that is, the collected fingerprint information matches with the fingerprint template), the user is allowed to use the data card to perform data transmission through the wireless network connected by the RF module. Alternatively, when the data card is powered on, the user is not allowed to use the data card and the RF module is in an “off” state. Next, after the fingerprint authentication is successful, the RF module starts to search and register with the network and the user is allowed to use the data card. In the end, the user can perform data transmission through the wireless network connected by the RF module. 
     In this embodiment, the user&#39;s fingerprint information is collected by using the fingerprint scanner on the data card and compared with the stored fingerprint template, and then the data card is controlled according to the comparison result output by the fingerprint authentication module. Thus, the authentication of the data card is realized through the fingerprint authentication, and related functions of the data card can only be used after successful fingerprint matching. As the security of the fingerprint authentication is much higher than the security of password authentication, the security of the data card is improved, and it is effectively ensured that the data card is not misappropriated. In addition, the fingerprint authentication is performed for the data card, so even if the user changed an SIM card, the data card still cannot be used as long as the fingerprint authentication is failed, so that the security of the data card is further improved. Moreover, the user does not need to remember a password during fingerprint authentication, and a network connection is automatically established upon successful fingerprint authentication, so that it becomes more convenient for the user and the complexity of the operations is reduced. 
       FIG. 2  illustrates a dial-up method of wireless Internet access equipment (such as a wireless network card) according to an embodiment of the present invention. The embodiment of the present invention provides a dial-up method for accessing wireless Internet, which includes the following steps. 
     Step  11 : The wireless Internet access equipment is registered with the wireless network. 
     In step  11 , after being powered up, the wireless Internet access equipment can register itself with the wireless network by using the existing technologies. The wireless network here may be 2G or Third Generation (3G) wireless networks such as GSM, CDMA, and UMTS. The wireless Internet access equipment is electrically connected to a PC. 
     Step  13 : Fingerprint information input by the user is obtained by using a fingerprint sensor. 
     The fingerprint sensor may be integrated in the wireless Internet access equipment, or disposed on the PC, or disposed in other equipment (such as a separated USB fingerprint sensor) and connected to the PC through various interfaces. After obtaining the fingerprint information input by the user, the fingerprint sensor sends the fingerprint information to a related module or equipment to be matched. 
     Step  15 : The input fingerprint information is matched with a stored fingerprint template. If the input fingerprint information successfully matches with the stored fingerprint template, step  17  is performed. If the input fingerprint information does not match with the stored fingerprint template, returns to step  13 , when the user inputs fingerprint information next time, the fingerprint information input by the user is obtained by the fingerprint sensor. 
     In this step, the wireless Internet access equipment or the PC can match the fingerprint information with the fingerprint template. For example, when the fingerprint template is stored in the wireless Internet access equipment, the wireless Internet access equipment receives the fingerprint information sent by the fingerprint sensor. Next, the fingerprint information is matched with the stored fingerprint template, and a matching result is sent to the PC for subsequent processes or subsequent processes are directly performed according to the matching result. Alternatively, when the fingerprint template is stored in the wireless Internet access equipment, the PC receives the fingerprint information sent by the fingerprint sensor and reads the fingerprint template from the wireless Internet access equipment. 
     Next, the PC matches the received fingerprint information with the read fingerprint template, and subsequent processes are performed according to the matching result or the matching result is sent to the wireless Internet access equipment for subsequent processes. Alternatively, when the fingerprint template is stored in the PC, the wireless Internet access equipment receives the fingerprint information sent by the fingerprint sensor and reads the fingerprint template from the PC. 
     Next, the wireless Internet access equipment matches the received fingerprint information with the read fingerprint template, and the matching result is sent to the PC for subsequent processes or subsequent processes are performed according to the matching result. Alternatively, when the fingerprint template is stored in the PC, the PC receives the fingerprint information sent by the fingerprint sensor and reads the fingerprint template from the wireless Internet access equipment. Next, the PC matches the received fingerprint information with the stored fingerprint template, and subsequent processes are performed according to the matching result, or the matching result is sent to the wireless Internet access equipment for subsequent processes. 
     Step  17 : The wireless Internet access equipment performs a dial-up connection and establishes a data service connection with the wireless network. 
     After establishing the data service connection, the wireless Internet access equipment may perform data service interaction with the wireless network, that is, the PC may access the Internet by using the wireless Internet access equipment. 
     Optionally, if the wireless Internet access equipment is a data card, referring to  FIG. 2 , before step  11 , the dial-up method of the wireless Internet access equipment may further include step  10 . After the data card is powered up, PIN code authentication is performed. If the PIN code authentication is successful, step  11  is performed. Otherwise, if the PIN code authentication is failed, all the SIM-related functions (including the dial-up connection function) of the data card cannot be used, and the above process is terminated or it is notified that the PIN code authentication is failed so that the user inputs the PIN code again. 
     Optionally, referring to  FIG. 2 , after step  11 , the method may further include step  12 : A dial-up connection is initiated according to operations of the user, and the user is prompted to input fingerprint information. In the actual operations, the process of the dial-up connection includes two steps. First, a dial-up command is delivered to the wireless Internet access equipment. Second, the wireless Internet access equipment establishes a data service connection with the wireless network according to the dial-up command and dial-up connection settings. Here, the initiation of the dial-up connection in step  12  may be that the PC delivers a dial-up command to the wireless Internet access equipment. Specifically, the delivery of the dial-up command may be that background software installed in the PC sends the dial-up command to the wireless Internet access equipment through the connection to the wireless Internet access equipment. For example, the background software sends the dial-up command to the wireless Internet access equipment by invoking an Application Programming Interface (API) of a dial-up connector of Windows. The prompting the user to input fingerprint information is optional and may be implemented in various modes, such as popping-up a prompt dialog box in the system of the PC, which is not limited here. The prompting the user to input fingerprint information in other steps is similar to step  12 , which will not be described again. 
     In addition, as step  12  is optional, step  12  may be omitted in other embodiments. For example, referring to  FIG. 3 , after step  11  is performed, step  22  is performed to prompt the user to input fingerprint information, or no operation is performed and the user is waited to input fingerprint information. When the fingerprint information input by the user is obtained by using the fingerprint sensor in step  13 , step  24  is performed. In step  24 , the PC automatically initiates a dial-up connection and delivers the dial-up command to the wireless Internet access equipment. Alternatively, referring to  FIG. 4 , after step  11  is performed, step  32  is performed. In step  32 , the PC automatically initiates a dial-up connection and delivers the dial-up command to the wireless Internet access equipment. When or after the dial-up command is delivered, step  34  may be performed to prompt the user to input fingerprint information, or no operation is performed and the user is waited to input the fingerprint information. 
     In step  17 , the performing the dial-up connection and establishing the data service connection with the wireless network by the wireless Internet access equipment may include: If the dial-up command has already been delivered to the wireless Internet access equipment before step  17 , the wireless Internet access equipment establishes a data service connection with the wireless network according to the dial-up command and the dial-up connection settings. Alternatively, if the dial-up command has not been delivered to the wireless Internet access equipment before step  17 , the wireless Internet access equipment first receives the dial-up command delivered by the PC, and then establishes a data service connection with the wireless network according to the dial-up command and the dial-up connection settings. 
     In other embodiments, it can be configured that different fingerprint information corresponds to different dial-up connection settings, that is, different fingerprint templates are bound to different dial-up connection settings respectively. Therefore, in step  15 , if the fingerprint information input by the user matches with one of the multiple stored fingerprint templates, in step  17 , the wireless Internet access equipment performs a dial-up connection and establishes a data service connection with the wireless network according to the dial-up connection settings corresponding to the matched fingerprint template. Thus, the fingerprint information of different fingers of the user can be bound to different dial-up connection settings, such as Access Point Name (APN) and authentication parameters. After the fingerprint authentication is performed and the fingerprint information is matched with the fingerprint template, corresponding dial-up connection settings can be found and a connection is initiated automatically in step  17 . By setting multiple fingerprint templates to bind different dial-up connection settings to the different fingerprint templates, various fingerprint dial-up modes can be provided for the same wireless Internet access equipment. Thus, the variety of the fingerprint authentication is improved and the flexibility of the dial-up of the wireless Internet access equipment is also improved. 
     It should be noted that, when the fingerprint authentication is used for the first time, it may be necessary to prompt the user to record a fingerprint template. The user inputs fingerprint information by using a fingerprint sensor, and the wireless Internet access equipment stores the fingerprint information collected by the fingerprint sensor as a fingerprint template, thus accomplishing the recording of the fingerprint template. In addition, for the wireless Internet access equipment, the above dial-up method of the wireless Internet access equipment may be set so as to turn on or off the dial-up function of the wireless Internet access equipment, where the dial-up function of the wireless Internet access equipment is implemented by the fingerprint authentication. Therefore, the recording of the fingerprint template can also be performed when the dial-up function of the wireless Internet access equipment is turned on, where the dial-up function of the wireless Internet access equipment is implemented by the fingerprint authentication. 
     In this embodiment, specifically, the wireless Internet access equipment may be various modem equipment or modules that can connect the PC to the Internet via the wireless network such as a data card, a wireless broadband module, a mobile phone, and a mobile Internet access terminal. 
     In this embodiment, the fingerprint information input by the user is obtained by using the fingerprint sensor, and the input fingerprint information is matched with the stored fingerprint template. When the matching is successful, a data service connection between the wireless Internet access equipment and the wireless network is established. Therefore, the dial-up function of the wireless Internet access equipment is protected by using the fingerprint authentication, so that it becomes very difficult to misappropriate the wireless Internet access equipment, and the security of the dial-up of the wireless Internet access equipment is improved. Moreover, as the wireless Internet access equipment automatically performs a dial-up connection when the fingerprint authentication is successful, the present invention provides a brand-new dial-up method of a wireless Internet access equipment, which can reduce the complexity of the dial-up connection and provide the availability and automation of the dial-up connection. 
     As shown in  FIG. 5 , an embodiment of the present invention provides a fingerprint identification data card, which includes a number of modules. A fingerprint collection module  51  is configured to collect user&#39;s fingerprint information by using a fingerprint scanner of the data card. A fingerprint authentication module  52  is configured to compare the collected fingerprint information with the stored fingerprint template to determine whether the collected fingerprint information matches with the fingerprint template, and to output a comparison result. A control module  53  is configured to perform corresponding control on the data card according to the comparison result output by the fingerprint authentication module  52 . A radio frequency module  54  is configured to establish a wireless connection with the Internet to receive and transmit data. 
     The corresponding control on the data card may be described as follows. The user is authenticated through the fingerprint authentication. If the collected fingerprint information matches with the fingerprint template, it is determined that the authentication is successful, and the user corresponding to the collected fingerprint information is allowed to access the Internet by using the data card. Otherwise, if the collected fingerprint information does not match with the fingerprint template, it is determined that the authentication is failed, and the user is not allowed to use the data card. In addition, or alternatively, one or more different fingerprint templates are stored, and each fingerprint template corresponds to a different operation. If the collected fingerprint information matched with any one of the fingerprint templates, the operation corresponding to the matched fingerprint template is performed. If the collected fingerprint information matches with none of the fingerprint templates, the data card may perform no operation or notify the user that the fingerprint authentication is failed through the data card or the user terminal connected to the data card. 
     For an implementation manner that the user corresponding to the collected fingerprint information is allowed to access the Internet by using the data card, for example, may be: The control module  53  may not execute the user&#39;s instructions (such as an instruction of connecting the Internet by using the RF module  54 , or an instruction of reading data stored in the data card and so on) before the authentication is successful. After the authentication is successful, the control module  53  enters a normal work state, and receives and executes the user&#39;s instructions, so that the user can access the Internet by using the data card, or read and write the data stored in the data card. 
     Similarly, a case the user is not allowed to use the data card can be as follows. The control module  53  does not execute the user&#39;s instructions, and thus does not accept the user&#39;s control over each module and function of the data card. Since the user is not allowed to use the data card if the collected fingerprint information does not match with the fingerprint template. The authentication of the data card is achieved through the fingerprint authentication. The user is only allowed to use the data card after the fingerprint is successfully matched, so that the right of using the data card is effectively controlled. 
     For an implementation manner of an operation corresponding to the matched fingerprint templates, for example, may be described as follows. If the data card includes two or more RF modules  54 , each RF module  54  corresponds to one or more fingerprint templates, and different RF modules  54  correspond to different fingerprint templates. According to the comparison result output by the fingerprint authentication module  52 , the control module  53  is configured to perform corresponding control on the data card. If the collected fingerprint information matches with one of the fingerprint templates, the radio frequency module  54  corresponding to the fingerprint template is initiated, so that the data card establishes a connection with the network by using the RF module  54  corresponding to the fingerprint template. 
     If the collected fingerprint information matches with none of the fingerprint templates, the user is notified, through the data card or a user terminal connected to the data card, that the fingerprint authentication is failed. Alternatively, if the data card includes one or more RF modules  54 , each RF module  54  corresponds to one or more turn on fingerprint templates and corresponds to one or more turnoff fingerprint templates, and different RF modules  54  correspond to different fingerprint templates. 
     The RF module  54  corresponding to the turn on fingerprint template is turned on if the collected fingerprint information matches with one of the turn on fingerprint templates, so that the data card establishes a connection with the network through the RF module  54  corresponding to the turn on fingerprint template. The RF module  54  corresponding to the turnoff fingerprint template is turned off if the collected fingerprint information matches with one of the turnoff fingerprint templates, so that the connection between the data card and the network through the RF module  54  corresponding to the turnoff fingerprint template is disconnected (if the RF module  54  corresponding to the turnoff fingerprint template does not establish a connection with the network, that is, the RF module  54  corresponding to the turnoff fingerprint template is in an “off” state, no operation is performed or the user is notified that the RF module  54  corresponding to the turnoff fingerprint template has already been turned off if the collected fingerprint information matches with the turnoff fingerprint template). 
     If the collected fingerprint information matches with none of the turn on fingerprint templates or the turnoff fingerprint templates, the user is notified that the fingerprint authentication is failed through the data card or the user terminal connected to the data card. When the turnoff fingerprint templates are set and the user does not need to use the network, for example only a function of a Secure Digital Memory Card (SD card) of the wireless data card is used, the user can choose to turn off the RF module  54  by fingerprinting, so as to avoid radiation and power consumption. 
     For example, the user registers the left little finger as a turnoff fingerprint template to turn off the RF module  54 . When the user swipes the left little finger, the control module  53  will turn off the RF module  54 , which will be turned on only when the user swipes the finger of relative functions. Since the RF module  54  is turned on after the fingerprint authentication is successful, the user can access the wireless network only after the fingerprint authentication is successful, so that the user&#39;s right for accessing the Internet by using the data card is effectively controlled. 
     It should be noted that, if the data card is a multi-mode data card, the multi-mode data card may include two or more RF modules, for example, any two or more of a GSM RF module, a WCDMA RF module, a CDMA RF module, a CDMA7000 RF module, and a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) RF module. For a multi-mode data card, the user may choose different network services by registering different fingerprint templates. For example, for a data card that supports both the GSM and the WCDMA, the user registers the left index finger to initiate the GSM network and registers the right index finger to initiate the WCDMA network. After inserting the data card, the user swipes the left index finger to initiate the RF module of the GSM, and at this time, the user can search and register with the GSM network. Similarly, the user swipes the right index finger to initiate the RF module of the WCDMA to use the WCDMA network. 
     The above data card further includes an interface module  55 , configured to connect the data card to the user terminal through various interfaces (such as a USB interface), so that the user terminal can perform data transmission with the network by using the data card. The interface module  55  here may be a cable interface (such as a USB interface) or a wireless interface (such as a Bluetooth interface). 
     In addition, the above data card may further include a notification module  56 , configured to notify, through the data card or the user terminal connected to the data card, the user of the fingerprint authentication result. 
     In addition, the above data card may further include a storage module  57 , configured to store the above fingerprint templates (including turn on fingerprint templates and/or turnoff fingerprint templates). The storage module  57  may be a memory or a non-volatile memory such as a Flash. The fingerprint templates stored in the storage module  57  may be input through the fingerprint collection module  51  and stored in the storage module  57  when the data card is set. For example, when the user initiates the data card for the first time, the data card prompts the user to input respective fingerprint templates, and at this time stores the fingerprint information input by using the fingerprint collection module  51  in the storage module  57  as fingerprint templates. Alternatively, during the use of the data card, the original fingerprint template is updated and replaced, and at this time the fingerprint information input by using the fingerprint collection module  51  is stored in the storage module  57  to replace the original fingerprint template. Before the update and replacement, it can be set that the update and replacement are only allowed when the user inputs the correct fingerprint information and the fingerprint authentication is successful. 
     It should be noted that, if the data card only has one RF module  54 , when the data card is powered on, the RF module  54  immediately starts to search and register with the network, and the control module  53  does not allow the user to use the data card. Next, after the fingerprint authentication is successful (that is, the collected fingerprint information matches with the fingerprint template), the control module  53  allows the user to use the data card to perform data transmission through the wireless network connected by using the RF module  54 . Alternatively, when the data card is powered on, the control module  53  does not allow the user to use the data card and the RF module is in an “off” state. Next, after the fingerprint authentication is successful, the RF module  54  starts to search and register with the network and the control module  53  allows the user to use the data card. In the end, the user can perform data transmission through the wireless network connected by using the RF module  54 . 
     In this embodiment, the user&#39;s fingerprint information is collected by using the fingerprint scanner on the data card and compared with the stored fingerprint template, and then the data card is controlled according to the comparison result output by the fingerprint authentication module. Therefore, the right control of the data card is achieved through fingerprint authentication, and related functions of the data card can only be used after successful fingerprint matching. Since the security of fingerprint authentication is much higher than the security of password authentication, the security of the data card is improved, and it is effectively ensured that the data card is not misappropriated. In addition, the fingerprint authentication is performed for the data card, so even if the user changes an SIM card, the data card still cannot be used as long as the fingerprint authentication is failed, so that the security of the data card is further improved. Moreover, during fingerprint authentication the user does not need to remember a password and the network connection is automatically established upon successful fingerprint authentication. Therefore, it becomes more convenient for the user, and the complexity of the operations is reduced. 
     As shown in  FIG. 6 , another embodiment of the present invention provides a wireless Internet access equipment, which includes a number of modules. A registration module  41  is configured to register the wireless Internet access equipment with a wireless network. A fingerprint identification module  42  is configured to obtain fingerprint information input by a user by using a fingerprint sensor and to match the input fingerprint information with a stored fingerprint template after the registration module  41  finishes registration. A processing module  43  is configured to perform a dial-up connection and to establish a data service connection between the wireless Internet access equipment and the wireless network when the input fingerprint information matches with the stored fingerprint template in the fingerprint identification module  42 . 
     Optionally, the wireless Internet access equipment may further include a storage module  44 , which is configured to store the fingerprint templates for modules such as the fingerprint identification module  42  and/or the processing module  43  to read and write. The storage module may be a memory or a non-volatile memory such as a Synchronous Dynamic Random Access Memory (SDRAM) or a flash chip. 
     Optionally, the wireless Internet access equipment may further include an RF module  45 , which is configured to send and receive wireless signals and to bear a dial-up connection between the wireless Internet access equipment and the wireless network. 
     Optionally, the wireless Internet access equipment may further include a fingerprint sensor  46 , which is configured to obtain fingerprint information input by the user, and send the obtained fingerprint information to the fingerprint identification module  42 . In other embodiments, the fingerprint sensor  46  may also not be integrated in the wireless Internet access equipment. For example, the fingerprint sensor  46  may be disposed in a PC or other equipment (such as a separated USB fingerprint sensor) and connected to the PC through various interfaces. 
     Optionally, the wireless Internet access equipment may further include an authentication module  47 , configured to perform PIN code authentication after the wireless Internet access equipment is powered on. 
     When the fingerprint authentication is used for the first time, or a dial-up function of the wireless Internet access equipment is turned on, where the dial-up function of the wireless Internet access equipment is implemented by the fingerprint authentication, the user needs to be prompted to input a fingerprint template. At this time, the fingerprint identification module  42  may be further configured to store the fingerprint information input by the user in the storage module  44  as a fingerprint template. 
     Referring to  FIG. 7 , the processing module  43  may further include a command receiving unit  431  and a dial-up connection unit  432 . The command receiving unit  431  is configured to receive a dial-up command delivered by the PC. The dial-up connection unit  432  is configured to establish a data service connection between the wireless Internet access equipment and the wireless network according to the dial-up command and dial-up connection settings received by the command receiving unit  431 . In addition, the occasion that the PC delivers the dial-up command may be referred to the related contents in the method embodiment, which will not be described here. Furthermore, the processing module  43  may further include a connection setting selection unit  433 , configured to read the dial-up connection settings bound to the matched fingerprint templates in the storage module  44  when binding different fingerprint templates to different dial-up connection settings respectively, so that the dial-up connection unit  432  establishes a data service connection between the wireless Internet access equipment and the wireless network according to the dial-up command and the dial-up connection settings bound to the matched fingerprint template. 
     In this embodiment, specifically, the wireless Internet access equipment may be various modem equipment or modules which can connect the PC to the Internet via the wireless network such as a data card, a wireless broadband module, a mobile phone, and a mobile Internet access terminal. 
     In this embodiment, the fingerprint information input by the user is obtained by the fingerprint sensor, and the input fingerprint information is matched with the stored fingerprint template. When the matching is successful, a data service connection between the wireless Internet access equipment and the wireless network is established. Therefore, the dial-up function of the wireless Internet access equipment is protected by using the fingerprint authentication, so that it becomes very difficult to misappropriate the wireless Internet access equipment, and the security of the dial-up of the wireless Internet access equipment is improved. Moreover, since the wireless Internet access equipment automatically performs the dial-up connection without the user&#39;s intervention when the fingerprint authentication is successful, an embodiment of the present invention provides a brand-new dial-up method of the wireless Internet access equipment, so as to reduce the complexity of the dial-up connection and provide the availability and automation of the dial-up connection.

     The wireless Internet access equipment  61  is configured to be registered with a wireless network. Fingerprint information input by a user is obtained by using a fingerprint sensor and matched with the stored fingerprint template. When the input fingerprint information matches with the stored fingerprint template, a dial-up connection is performed and a data service connection between the wireless Internet access equipment  61  and the wireless network is established. 
     The computer  62  is configured to control the wireless Internet access equipment  61  to perform a dial-up connection, and perform data services by using the data service connection between the wireless Internet access equipment  61  and the wireless network. 
     The wireless Internet access equipment  61  and the computer  62  can be connected through various interfaces such as the USB, the Express Card, the Personal Computer Memory Card International Association (PCMCIA), or the Peripheral Controller Interface (PCI), and transmission of data and commands is performed.
