     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The basic concept of the disclosure is: setting on a terminal a detection device, setting on a stylus a label device capable of being detected by the detection device, the detection device detecting for label information preconfigured in the label device, and authenticating the stylus according to a detection result. 
     Hereinafter, a detailed description is given to the embodiments of the disclosure with reference to the accompanying drawings. 
     Embodiment 1 
       FIG. 1  is a flowchart of a terminal authentication method according to an embodiment of the disclosure, and as shown in  FIG. 1 , the method includes the following steps: 
     S 01 , a detection device is set on a terminal, and a label device capable of being detected by the detection device is set on a stylus. 
     S 02 , the detection device reads the label information preconfigured in the label device and matches the read label information with authentication information preconfigured in the terminal, and if the match result is that they are consistent with each other, perform S 03 , and if the match result is that they are inconsistent with each other, perform S 04 . 
     S 03 , the terminal allows to respond to an operation of the stylus. 
     S 04 , the terminal rejects to respond to an operation of the stylus. 
       FIG. 2  is a schematic diagram of a terminal according to an embodiment of the disclosure, and as shown in  FIG. 2 , a terminal  1  is set thereon with a detection device  11 , and the detection device  11  is configured to detect for label information preconfigured in a label device set on a stylus and authenticating the stylus according to a detection result. 
     The terminal in this embodiment includes mobile phone, MP3 player, MP4 player, and so on, but not limited to the listed. The method for the detection device to read the label information preconfigured in the label device in this embodiment includes one of contactless reading and contact reading, and the preferred method is contactless reading, which preferably is: setting on the terminal a radio frequency identification (RFID) reader or a near field communication (NFC) reader as the detection device, correspondingly setting on the stylus an RFID chip or an NFC chip as the label device; the method for setting the RFID chip or the NFC chip on the stylus includes methods such as embedding or outside adhering and so on; taking setting on the terminal the RFID reader as the detection device and correspondingly setting on the stylus the RFID chip as the label device as an example, the RFID reader continuously emits a radio frequency signal with a specific frequency through an antenna, which forms an electromagnetic field in a certain range of the RFID reader, and after the RFID chip enters into the electromagnetic field, the internal circuit is excited to produce a sensing current, acquires energy from the sensing current, and sends the label information stored in the RFID chip to the outside, and the RFID reader acquires the label information through the antenna, and reads the label information of the stylus preconfigured in the RFID chip, which label information includes unique identification information of the stylus where it is located. 
     Preferably, during the process that the stylus operates the terminal, the stylus may be authenticated continuously or with an interval, so as to prevent other stylus continuously operating the terminal and leaking the user information. 
     Preferably, after the stylus has passed the authentication, if the stylus does not perform any operation on the terminal within a certain period of time, the terminal can be configured to automatically disable the function of responding to the stylus, and if the stylus is intended to continuously operate the terminal, it has to be authenticated again. 
     Preferably, when the user closes the screen, the terminal can automatically disable the function of responding to the stylus, and the stylus will be re-authenticated at next time. 
     Preferably, an easy operation method can be configured in the terminal so that the user conveniently starts up the stylus authentication process, for example, a control module for enabling and/or disabling the authentication function can be configured in the terminal, the control module includes a plurality of implementations, it can be a key, or an authentication response region can be configured on the screen, and so on. There are many kinds of keys, for example, a method of multiplexing a combination of some existing keys of the terminal and long-time press-down, for example, a method for specially configuring a key for enabling and/or disabling the authentication function, please refer to  FIG. 3 ,  FIG. 3  is a schematic diagram of a terminal according to another embodiment of the disclosure: a terminal  1  is set thereon with a detection device  11  and is also set thereon with a key  12  for enabling and/or disabling the authentication function. In a normal standby state, the user presses down the key to enable the authentication function, and the RFID reader set in the terminal starts to emit an electromagnetic field and prepares to read label information fed back by an RFID label, and this key can also be used to disable the authentication function according to the demand of the user him/herself. An authentication control touchscreen region is set on the screen, please refer to  FIG. 4 ,  FIG. 4  is a schematic diagram of a terminal in another embodiment of the disclosure: a terminal  1  is set thereon with a detection device  11  and is also set thereon with an authentication control touchscreen region  13  for enabling and/or disabling the authentication function, and the user can fill the blank region according to the prompt of the terminal in accordance with a certain track or a target sliding block to operate the touchscreen so as to realize the enabling and/or disabling of the authentication function. 
     Preferably, the authentication information preconfigured in the terminal includes information for authenticating one or more styluses, and a stylus addition/deletion module can be set in the terminal, through which information for authenticating a plurality of styluses can be pre-stored in the terminal and the user can be allowed to add other styluses which can respond to the terminal, so as to prevent the problem that the user cannot operate the terminal after losing a specific stylus; and in order to prevent a non-terminal user adding a stylus which can respond arbitrarily, when the user starts up this function through the menu, the terminal can instruct the user to input the password first and start this function only if the password is correct, when the user inputs the correct password, the detection device of the terminal, such as the RFID reader, emits a driving electromagnetic field and starts to read the new label information, if the label information is not read out within a certain period of time, it will be timed out and exit, and if the new label information of the stylus is read within a certain period of time, the label information can be stored in the terminal as new stylus information and used as authentication information for authenticating the stylus subsequently. 
     When the terminal can respond to a plurality of styluses, a stylus list can be configured in the terminal, and after the detection device of the terminal reads the label information of the stylus, it matches the label information with the information of a first stylus in the stylus list of the terminal, if the matching has failed, it continues to match same with the information of other styluses in the list, if the matching succeeds, the terminal deems that this stylus is one to which the user allows to respond, the terminal starts to correspondingly respond to the input of the stylus, and if there is no stylus information which matches successfully after the matching of all the information is done, the terminal deems that this stylus is one to which the user does not allow to respond, and the terminal rejects to respond to any operation of this stylus. 
     Accordingly, this addition/deletion stylus module can also be configured to allow the user to delete some styluses which can be authenticated and respond normally at present under a certain condition such as the correct password is input so that they cannot be responded by the terminal continuously. 
     For further improving the user experience, when adding new stylus information in the terminal, the user can also be prompted to make specific personalized settings for this stylus, for example, setting a stylus management module in the terminal, which module has functions such as renaming the stylus, adding a display picture, setting a group, setting a response ring, setting an authentication pass prompt sound, setting an application scenario mode and so on. 
     If the user has set a name for a stylus, and set a corresponding picture, response ring, authentication pass prompt sound for the stylus, when passing the authentication, the preset authentication pass prompt sound can be played, and the name and picture of this stylus can be displayed in a specific location, and the preset respond ring can be played during the operation of the stylus. 
     If the user has preset a scenario mode corresponding to the use of the stylus, for example, when using a certain stylus, the terminal changes to a mute mode or a corresponding special telephone, clock ring and so on, then after the stylus passes the authentication, the terminal automatically switches to the corresponding scenario mode. If the user has preset a wallpaper, desktop, ring and so on corresponding to this stylus, then after the stylus passes the authentication, the terminal automatically switches to the corresponding wallpaper, desktop and ring. If the user has preset a call control corresponding to this stylus, for example, any call will not be answered but transferred to a certain number when using a certain stylus, then after the stylus passes the authentication, the terminal automatically enable the function of corresponding call control. If the user has preset a black/white list corresponding to this stylus, then after the stylus passes the authentication, the terminal automatically starts up this black/white list. The stylus authentication can also be combined with the screen unlock operation of the terminal, for example, the screen is unlocked automatically after the authentication succeeds. For the terminal, these personalized settings can be deleted when deleting the stylus, and can also be recovered when recovering the stylus. 
       FIG. 5  is a schematic diagram of a stylus management interface in a terminal in an embodiment of the disclosure, and as shown in  FIG. 5 : the stylus management interface includes a stylus list, an option menu and an exit menu, the stylus list is used for listing the names of the styluses to which the terminal can respond, such as A, B and C, the option menu includes options of adding a stylus, deleting a stylus and setting a stylus and so on, which can be displayed by way of setting a pull-down menu in the option menu, and after clicking the option of setting a stylus, the following options can be entered by way of setting a pull-down menu in the stylus option menu: 
     1) renaming a stylus: modifying the display name of a selected stylus. 
     2) setting a picture: resetting the display picture of the selected stylus. 
     3) setting a response ring: resetting the operation response ring of the selected stylus. 
     4) setting a scenario mode: setting a scenario mode to which the terminal automatically switches when using a certain stylus. 
     5) setting prompt words: setting the personalized prompt words which are displayed automatically on the terminal interface when using a certain stylus. 
     6) group management: grouping the existing styluses and managing same accordingly.
