步骤407：第二发射电路326将所述第二编码消息无线发送出去；
步骤408：第二接收电路313接收第二编码消息；
步骤409：第二解码电路314对第二编码消息进行解码，得到携带禁止一次拍照内容的第二解码消息；
步骤410：计数电路315累加收到第二解码消息的次数，并进行判断；若大于阈值，进行步骤411，若小于阈值，进行步骤401；
计数电路315的计数方式要根据所设的阈值来决定，例如阈值设为3，则计数电路可以是由三进制的计数器组成的电路。
步骤411：计数电路315在收到第二解码消息的次数大于阈值时，通过第一控制电路316控制第一编码电路311产生关闭拍摄设备320的第三编码消息；
阈值可以根据用户的需求进行设定，当计数电路在收到第二解码消息的次数大于阈值时，计数电路315则发送一信号到控制电路，例如一个高电平；第一控制电路316收到该信号后则控制第一编码电路311产生关闭拍摄设备320的第三编码消息，由于第一编码电路311前后会发出第一编码消息及第三编码消息两种不同的消息，可以通过使第一编码电路311产生两种不同的消息，也可以通过对第一编码消息进行处理产生第三编码消息。
步骤412：第一发射电路312将第三编码消息无线发送出去；
步骤413：第一接收电路321无线接收第三编码消息；
步骤414：第一解码电路322对第三编码消息进行解码，得到携带关闭拍摄设备320内容的第三解码消息；
步骤415：第二控制电路323按照第三解码消息，关闭拍摄设备320。
关闭拍摄设备320是直接通过拍摄设备320的系统应用层发送命令，对拍摄设备320进行强制关机。强制关机可以是切断电源或者其他控制方式。例如通过framework传递给kernel执行关机任务，具体关闭流程如图5所示。
区别于现有技术，本实施方式除了第一实施方式的有益效果外，还在拍摄设备320上增加了第二编码电路325，用于反馈禁止拍照的消息；在穿戴设备310上增加了累积反馈信号的计数电路315，对第一编码电路311进行控制发射具有关闭拍摄设备320的第三编码消息。通过上述方式，穿戴设备310在屡次发送禁止拍照命令后，若拍摄设备320仍然有拍摄动作，就强制关闭拍摄设备320，有效地防止了偷拍行为，保护了用户的隐私。
参阅图6，本发明防偷拍系统的第三实施方式包括：
一具体实施穿戴设备终端的电路。
原实施方式中的第一编码电路、第一发射电路、第二接收电路、计数电路以分别对应本实施方式的多谐震荡电路601、红外发射传感器602、红外光敏电阻603、数字计数器604，取消第二解码电路，第一控制电路的功能由三极管代替。
如图6所示，红外光敏电阻603连接计数器604的输入端，计数器604的输入端连接三极管605的基极，三极管605的集电极连接多谐振荡电路601的引脚7，三极管605的发射极连接电阻606的第一端，电阻606的第二端连接多谐振荡电路601的引脚2和6，另外，电阻607的第一端连接三极管605的集电极，电阻607的第二端连接多谐震荡电路的引脚2和6，电路其他部分的连接详见图6。
如图7所示，本实施方式的具体实施步骤如下：
步骤701：多谐震荡电路601产生脉冲信号1；
该多谐震荡电路601可以由其他产生脉冲信号的电路替代。
步骤702：红外发射传感器602将脉冲信号1发送出去；
拍摄设备在收到该脉冲信号1时禁止摄像头拍照；在禁止拍照后发射一红外信号。
步骤703：红外光敏电阻603接收拍摄设备反馈的禁止拍照的红外信号；
步骤704：计数器604对接收该红外信号的次数进行累加；
步骤705：计数器604对接收该红外信号的次数进行累加大于预设阈值时，计数器604发射一高电平；
步骤706：多谐震荡电路601产生脉冲信号2。
高电平导致三极管导通，与多谐震荡电路连接的电阻降低，多谐震荡电路发射脉冲信号2；
拍摄设备在收到该脉冲信号2时关闭拍摄设备。
本实施方式将第一、第二实施方式的各个电路集成为一个电路，采用红外信号作为传感信号，由于红外信号对传输距离的要求，拍摄设备的红外接收传感器应位于摄像头1cm之内，红外发射传感器也应位于摄像头附近。
区别于现有技术，本实施方式在穿戴设备上采用一个电路完成防止偷拍的功能，简化了电路，不影响穿戴设备的原有功能，并且能起到第一、第二实施方式相同的作用。
参阅图8，本发明穿戴设备的第四实施方式包括：
穿戴设备800，穿戴设备800包括依次连接的第一编码电路801以及第一发射电路802，还包括依次连接的第二接收电路803、第二解码电路804、计数电路805以及第一控制电路806，第一控制电路806连接第一编码电路801。
参阅图9，本发明拍摄设备的第五实施方式包括：
拍摄设备900，拍摄设备900包括依次连接的第一接收电路901、第一解码电路902、第二控制电路903以及摄像头904，还包括依次连接的第二发射电路906以及第二编码电路905，第二编码电路905连接第二控制电路903。
第四实施方式及第五实施方式的具体实施步骤与上述第一实施方式、第二实施方式及第三实施方式类似，这里不再赘述。
随着社会的发展，人们的保护隐私意识和自身素质的提高，将来的穿戴设备或者拍摄设备可以加入上述防偷拍设置，因此，穿戴设备或拍摄设备中的一个终端也在本发明的保护之列。
此外，上述各实施方式中的编码电路或解码电路也可以去掉，可以如图6所示实施方式一样利用模拟电路来发射和接收信号，同时识别信号，无需编码或解码的处理。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
