在本实施例中提供了一种运行于上述移动终端或网络架构的防拆卸处理方法，图2是根据本公开实施例的防拆卸处理方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，获取用于指示终端是否被拆卸过的信号，其中，用于指示终端是否被拆卸过的信号包括以下至少之一：与所述终端的后盖对应的触控开关相连的输入输出IO口的电平信号；与终端的后盖对应的螺丝孔相连的IO口的电平信号；终端的后盖与终端之间的压力信号；终端的后盖区域的磁通量信号。；
步骤S204，判断信号是否发生变化；
步骤S206，在判断结果为所述信号发生变化的情况下，确定终端被拆卸过。
通过上述步骤，由于根据获取的用于指示终端是否被拆卸过的信号确定终端是否被拆卸过，无需使用防伪贴纸，使得用户无需再通过肉眼观测防伪贴纸是否被拆除确定终端是否被拆卸过，也无需考虑防伪贴纸是否被仿制的问题，因此，可以解决相关技术中通过防伪贴纸确定终端是否被拆卸不准确的问题。
可选地，用于指示终端是否被拆卸过的信号为与触控开关相连的输入输出IO口的电平信号的情况下，获取用于指示终端是否被拆卸过的信号包括：检测触控开关的状态；当检测到触控开关为闭合状态的情况下，获取与触控开关相连的输入输出IO口的第一电平信号；当检测到触控开关为打开状态的情况下，获取与触控开关相连的输入输出IO口的第二电平信号；其中，终端的后盖为打开状态时，触控开关为打开状态。
例如，用于指示终端是否被拆卸过的信号为与触控开关相连的输入输出IO口的电平信号的情况下，在硬件实现上，终端(例如，手机)可以包括基带处理器、电源模块、射频模块和液晶显示器(Liquid Crystal Display，简称为LCD)模组、触控开关和微处理器(Microcontroller Unit，简称为MCU)。触控开关焊接在终端的印刷电路板(Printed Circuit Board，简称为PCB)上，通过和手机后盖接触，当终端后盖盖上时，开关的状态是关闭状态，对应电平是0低电平；当终端后盖打开时，这时触控开关和后盖分离，开关会弹开，此时开关的状态 是开的状态，对应电平是1高电平。在工作的过程中，将会记录电平状态以及电平变化过程的时间点，同时会统计电平变化的次数。电平的变化和次数存储在MCU的存储器里面。MCU可以对触发开关电平变化进行采集，以及电平变化次数的统计，并通过相应通信接口和基带处理器相连，便于基带处理器对MCU内部数据的读取。触发开关、MCU和基带处理器连接的方式如图3所示。
又例如，用于指示终端是否被拆卸过的信号为与触控开关相连的输入输出IO口的电平信号的情况下，在软件实现上，可以包括客户端、开关状态检测模块、开关状态变化统计模块等。开关状态检测模块可以对触发开关的电平进行检测，也就是终端后盖是否打开进行检测；开关状态变化统计模块可以对电平变化的次数进行统计，也就是终端后盖被打开的次数进行统计；客户端，可以由基带处理器对MCU内部数据进行读取，包括触发开关开闭的时刻，以及开闭的次数，也就是终端后盖被打开的时间点和被打开的次数。

例如，用于指示终端是否被拆卸过的信号为与终端的后盖对应的螺丝孔相连的IO口的电平信号的情况下，在硬件实现上，终端可以包括基带处理器、电源模块、射频模块和LCD模组、MCU，同时终端内部PCB上的螺丝孔进行了独特设计，这个螺丝孔与MCU的IO口相连，同时螺丝孔上下面都是绝缘的，终端本体是地，当有螺丝在的时候，这个螺丝孔与地相连，即MCU相应的IO口电平是0低电平，由于与螺丝孔相连的IO口上拉处理，所以当螺丝被拆除时，MCU对应的IO口电平为1高电平。通过MCU的IO口电平变化，区分螺丝存在与否，即区分终端后盖拆卸的情况。在工作的过程中，MCU将会记录电平状态以及电平变化过程的时间点，同时会统计电平变化的次数，电平的变化和次数存储在MCU的存储器里面。MCU并通过相应通信接口和基带处理器相连，便于基带处理器对MCU内部数据的读取。螺丝孔、MCU和基带处理器连接的方式如图4所示。
又例如，用于指示终端是否被拆卸过的信号为与终端的后盖对应的螺丝孔相连的IO口的电平信号的情况下，在软件实现上，可以包括客户端、螺丝孔电平状态检测模块、螺丝孔电平状态变化统计模块等。螺丝孔电平状态检测模块可以对螺丝孔的电平进行检测，也就是终端后盖是否打开进行检测；螺丝孔电平状态变化统计模块可以对电平变化的次数进行统计，也就是终端后盖被打开的次数进行统计；客户端，可以由基带处理器对MCU内部数据进行读取，包括螺丝孔电平变化的时刻，以及变化的次数，也就是终端后盖被打开的时间点和被打开的次数。
可选地，用于指示终端是否被拆卸过的信号为终端的后盖与终端之间的压力信号的情况下，获取用于指示终端是否被拆卸过的信号包括：通过压力传感器获取终端的后盖为闭合状态时的终端与终端的后盖之间的第一压力信号；通过压力传感器获取终端的后盖为打开状态时终端与终端的后盖之间的第二压力信号。
例如，用于指示终端是否被拆卸过的信号为终端的后盖与终端之间的压力信号的情况下，在硬件实现上，终端可以包括基带处理器、电源模块、射频模块和LCD模组等，不同之处在于增加了一个压力传感器和一个MCU。压力传感器、MCU和基带处理器连接方式如图5所示。当终端后盖被拆除时，压力传感器采集到一个压力值，当终端后盖在终端上时，即终端未被拆卸，压力传感器采集到另外一个压力值。通过压力值的变化的时间和次数进行终端后盖被拆卸的时刻和次数进行统计。在工作的过程中，MCU将会记录压力传感器压力值变化的时间点，同时会统计压力值变化的次数，压力值的变化时刻和压力值变化的次数存储在MCU的存储器里面。MCU并通过相应通信接口和基带处理器相连，便于基带处理器对MCU内部数据的读取。
又例如，用于指示终端是否被拆卸过的信号为终端的后盖与终端之间的压力信号的情况下，在软件实现上，可以包括客户端、压力传感器状态检测模块、压力传感器状态变化统计模块等。压力传感器状态检测模块可以对压力传感器压力值进行检测，也就是终端后盖是否打开进行检测；压力传感器状态变化统计模块可以对压力传感器压力值变化的次数进行统计，也就是终端后盖被打开的次数进行统计；客户端，可以由基带处理器对MCU内部数据进行读取，包括压力传感器压力值变化的时刻，以及变化的次数，也就是终端后盖被打开的时 间点和被打开的次数。

例如，都包括基带处理器、电源模块、射频模块和LCD模组等，不同之处在于增加了一个霍尔传感器和一个MCU，同时在终端后盖处某一个特定位置放置了一定大小的具有磁性的磁铁。霍尔传感器、MCU和基带处理器连接方式如图6所示。在设计的过程中，将霍尔传感器和MCU单独作为一个小的系统，设计在终端电路板上，同时在终端后盖某个位置将会增加一块相应的磁铁，根据终端磁通量的变化来检测终端的后盖的拆卸的情况。设定，当终端后盖未拆卸的情况下，霍尔传感器检测到的磁通量是a，当终端后盖被拆卸时，霍尔传感器检测到的磁通量是b；在工作的过程中，MCU将会记录霍尔传感器的磁通量变化的时间点，同时会统计霍尔传感器磁通量变化的次数，磁通量的变化时刻和磁通量变化的次数存储在MCU的存储器里面。MCU并通过相应通信接口和基带处理器相连，便于基带处理器对MCU内部数据的读取。
又例如，在软件实现上，可以包括客户端、磁通量检测模块、磁通量变化统计模块等。磁通量检测模块可以对霍尔器件附件的磁通量大小进行检测，即根据磁通量的大小来判断终端后盖是否被拆卸；磁通量变化统计模块可以对磁通量变化的次数进行统计，变化次数根据磁通量值a和b的变化来判断，即终端后盖被打开的次数进行统计；客户端，可以由基带处理器对MCU内部数据进行读取，包括霍尔传感器测量的磁通量的值和测量的时间点，以及变化的次数，也就是终端后盖被打开的时间点和被打开的次数。
可选地，在确定终端被拆卸过之后，还包括：获取信号发生变化的时间点和信号发生变化的次数；根据时间点确定终端被拆卸的时间点，以及根据次数确定终端被拆卸的次数。可选地，在获取信号发生变化的时间点和信号发生变化的次数之后，还包括：存储时间点和次数；和/或，显示时间点和次数。通过上述步骤，可以记录电子防伪贴被触发的时间和触发次数，从而更加准确的实现防伪功能。
