第一电子设备在大于预设的阈值个数的运动状态下，均被蓝牙外设的伴随，更符合第一电子设备被蓝牙外设跟踪的规律；在第二类型的扫描记录的集合中包括位置信息的集合指示的距离大于预设的距离阈值的情况下，进一步符合第一电子设备被蓝牙外设跟踪的规律；进一步符合第一电子设备被蓝牙外设跟踪的规律。这样，结合上述的3个条件，确定被蓝牙外设跟踪的可靠性更高。

具体实施方式
为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一值和第二值仅仅是为了区分不同的值，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
蓝牙外设是一种可以周期性广播第一蓝牙信号的蓝牙设备。用户可以将蓝牙外设与随身携带的物品(如钥匙、背包等)放在一起。用户可以获取蓝牙外设的位置信息(即物品的位置信息)，来定位物品。
如图1所示，用户可以将手机200与蓝牙外设300建立蓝牙连接。当用户无法找到随身携带的物品时，用户可以通过手机200查找蓝牙外设300所在的位置，来定位与蓝牙外设300放在一起的物品。
一方面，仍如图1所示，在手机200仍与蓝牙外设300保持连接的情况下，手机200可以接收到蓝牙外设广播的第一蓝牙信号。进而，手机200在被用户触发查找的功能后，根据第一蓝牙信号检测蓝牙外设300的位置信息，进而显示图2所示的物品定位界面201，在物品定位界面201显示有“XX物品在右侧，距您6m”。即，物品定位界面201显示了物品的位置信息。另外，物品定位界面201还包括声控按钮202。手机200还可以响应于用户对声控按钮202的触发操作，控制蓝牙外设300发声，以协助用户寻找与蓝牙外设300放在一起的物品。
在另一方面，当手机200与蓝牙外设300断开连接的情况下，与蓝牙外设300在预设距离范围内的电子设备可以接收到蓝牙外设广播的第一蓝牙信号，并向云服务器发送电子设备的位置信息。手机200在被用户触发查找的功能后，从云服务器获取电子设备的位置信息。进而，显示图3所示的物品定位界面203。在物品定位界面203中显示了电子设备在地图中的位置信息。由于电子设备与蓝牙外设300在预设的距离范围内，如此用户可以通过电子设备的位置信息推测出蓝牙外设300的位置，以方便找回遗失的物品。
然而，针对蓝牙外设的应用存在一定的安全隐患，即用户可能将此类蓝牙外设用于跟踪其他用户。比如，若用户B将其蓝牙外设放置在用户A的特定物品，如车辆，衣物口袋中，使用户A在不知情的情况下携带蓝牙外设移动。由此，用户B可以从云服务器查询到与蓝牙外设在预设距离范围内的电子设备的位置信息。进而，用户B可以通过查询的电子设备的位置信息，推测出蓝牙外设的位置信息，从而实现对用户A的跟踪。如此，需要识别出跟踪用户A的蓝牙外设。
如图4所示，携带手提包和第一电子设备1503的用户A、以及携带手提包的用户B乘同一辆公交车出行。其中，用户A的手提包中包括第一蓝牙外设1502，用户B的手提包中包括第二蓝牙外设1501，而且第一蓝牙外设1502为第一电子设备1503认证合法的设备。其中，第一蓝牙外设1502、第二蓝牙外设1501均周期性向周围广播蓝牙信号。如此，用户A的第一电子设备1503能够持续检测到位于用户B的手提包中的第二蓝牙外设1501广播的蓝牙信号。这样一来，第一电子设备1503确定被第二蓝牙外设1501跟踪。
然而，实际上用户A的第一电子设备1503和用户B的第二蓝牙外设1501仅仅是在同乘一辆车，并不存在跟踪行为。即上述用户A的第一电子设备1503确定被第二蓝牙外设1501跟踪为误确定的结果，准确度低。
有鉴于此，本申请提供了一种设备跟踪检测方法，应用于第一电子设备。该方法包括：在连续多次运动状态发生变化时，在预设时长内均存在第一类型的扫描记录，确定第一电子设备被蓝牙外设跟踪。可以理解地，在第一电子设备在连续多个不同的运动状态下均被蓝牙外设伴随，即蓝牙外设伴随用户的运动状态变化而变化，可以理解为“物随人动”，更符合第一电子设备被蓝牙外设跟踪的逻辑常识。如此，第一电子设备确定被蓝牙外设跟踪，准确度高。

调制解调处理器可以包括调制器和解调器。其中，调制器用于将待发送的低频基带信 号调制成中高频信号。解调器用于将检测到的电磁波信号解调为低频基带信号。随后解调器将解调得到的低频基带信号传送至基带处理器处理。低频基带信号经基带处理器处理后，被传递给应用处理器。应用处理器通过音频输出设备(不限于扬声器170A，受话器170B等)输出声音信号，或通过显示屏194显示图像或视频。在一些实施例中，调制解调处理器可以是独立的器件。在另一些实施例中，调制解调处理器可以独立于处理器110，与移动通信模块150或其他功能模块设置在同一个器件中。

在一些实施例中，蓝牙模块可以通过周期性地接收蓝牙外设发出的第一蓝牙信号，然后将蓝牙外设发送的第一蓝牙信号上报给第一电子设备100的处理器110，处理器110收到蓝牙外设的第一蓝牙信号后，向云服务器发送第一电子设备100的位置信息。蓝牙模块收到蓝牙外设的第一蓝牙信号，表明蓝牙外设位于第一电子设备100附近，因此第一电子设备100上报的位置信息，相当于是蓝牙外设的位置信息。

在一些可能的实施例中，蓝牙外设可以是小型的具有蓝牙功能的设备。示例性地，本申请实施例中的蓝牙外设具体可以是Apple公司推出的一款名为

下面，说明对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以独立实现，也可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。请参阅图7，本申请实施例提供的设备跟踪检测方法可以由第一电子设备100执行。本申请实施例提供的设备跟踪检测方法，具体可以包括如下步骤：
S401：第一电子设备100开启预设模式。其中，在预设模式下第一电子设备100能够接收第一蓝牙信号。
可以理解地，第一电子设备100仅在预设模式下才接收第一蓝牙信号，可以节省功耗，且更符合用户的需求。
在一些实施例中，第一电子设备100可以显示第一界面，第一界面包括第一控件，第一控件用于开启或关闭预设模式。如此，第一电子设备100响应于用户对第一控件的开启操作，开启预设模式。其中，预设模式可以理解为“跟踪检测模式”。如此，用户可以通过触发第一界面中的第一控件，实现开启预设模式，方便快捷。
例如，如图8所示，第一电子设备100在出厂后被首次开机时，第一电子设备响应于用户对锁屏界面(附图中未示)的解锁操作，显示系统桌面501。第一电子设备100显示系统桌面501(即第一界面)。进而，第一电子设备100在系统桌面501显示第一提示框502。第一提示框502包括第一控件503。第一控件503的一侧包括文字信息“启动报告附近的陌生蓝牙外设300”，即第一控件503用于开启或关闭预设模式。第一电子设备100可以响应于用户对第一控件503的开启操作，开启预设模式。如此，用户可以在系统桌面501即可开启预设模式，方便快捷。
再例如，如图9中的(a)所示，第一电子设备100可以响应于用户对系统桌面的“设置”图标的触发操作，显示功能列表界面601。功能列表界面601包括安全设置选项602，第一电子设备100可以响应于用户对安全设置选项602的触发操作，显示安全功能列表界面603(即第一界面)。如图9中的(b)所示，安全功能列表界面603包括第一控件604。第一控件604的一侧包括文字信息“报告附近的陌生蓝牙外设300”，即第一控件604用于指示开启或关闭预设模式。第一电子设备100可以响应于用户对第一控件604的开启操作，开启预设模式。如此，用户可以在任一时刻在触发“设置”图标后，即可开启预设模式，方便快捷。
在另一些实施例中，步骤S401中，第一电子设备100还可以检测到用户点亮屏幕后就开启预设模式，还可以开机后直接开启预设模式等，在此不作限定。
另外，第一电子设备100也可以默认处于预设模式。在这种情况下，上述的S401可以省略。
S402：第一电子设备100构造第一信号过滤器。
本申请实施例提供的方法，需要基于第一电子设备100接收到的第一蓝牙信号来实现。其中，第一蓝牙信号是指任一蓝牙外设300广播的蓝牙信号。所以在步骤S402中，第一电子设备100需要针对第一蓝牙信号构造对应的第一信号过滤器，然后将第一信号过滤器配置给第一电子设备100的蓝牙控制器，使第一电子设备100的蓝牙控制器开始扫描蓝牙信号，并利用第一信号过滤器从接收到的多个蓝牙信号中识别出第一蓝牙信号。进而，第一电子设备100基于是否检测到第一蓝牙信号，可以判断出周围一定距离内是否有蓝牙外设300。
第一电子设备100可以按如下方式构造第一信号过滤器：第一电子设备100需要获得第一蓝牙信号时，可以调用第一电子设备100的操作系统提供的过滤器构造函数，将第一蓝牙信号的特征数据输入过滤器构造函数，由此构造出一个针对第一蓝牙信号的第一信号过滤器。第一电子设备100每接收到一个蓝牙信号，可以将这个蓝牙信号和已配置的每一个信号过滤器进行比对，如果发现蓝牙信号携带有一个第一信号过滤器的特征信息，第一电子设备100就可以识别出这个蓝牙信号为第一信号过滤器对应的类型的信号，即蓝牙外设300广播的第一蓝牙信号。
其中，第一蓝牙信号的特征数据可以包括但不限于蓝牙外设名，蓝牙外设300的MAC地址，服务数据，厂商数据等。可以理解的是，特征数据也可以包括其他类型的数据，本申请实施例对此不做限定。服务数据用于指示第一蓝牙信号的作用，厂商数据用于指示发送第一蓝牙信号的设备的制造厂商。示例性地，第一信号过滤器可以是Findmy过滤器。
在另一些实施例中，第一电子设备100可以预先配置第一信号过滤器，这样一来，上述的S402可以省略。
S403：第一电子设备100注册运动状态监听器，并基于运动状态监听器监听运动状态。
其中，运动状态监听器位于第一电子设备100的软件系统的框架层。运动状态监听器用于监听第一电子设备100的运动状态。
需要说明的是，上述的S402与S403之间可以没有先后顺序。可以理解地，运动状态监听器也可以是第一电子设备100预先注册的，如此，S403可以省略。
S404：第一电子设备100通过第一信号过滤器接收第一蓝牙信号。
可以理解地，在第一电子设备100的一定距离阈值内具有蓝牙外设300时，第一电子设备100可以通过第一信号过滤器接收到蓝牙外设300每隔预设时长(如6s)广播的第一蓝牙信号。
S405：第一电子设备100生成第一类型的扫描记录。其中，第一类型的扫描记录与第一蓝牙信号携带的物理地址存在对应关系。
在一些可选的实施例中，第一电子设备100可能会通过第一信号过滤器接收到多个蓝牙外设300的第一蓝牙信号。其中，每个第一蓝牙信号携带有物理地址。可以理解地，不同的蓝牙外设300广播的第一蓝牙信号携带的物理地址不同。因此，第一电子设备100可以通过识别每个第一蓝牙信号携带的物理地址，将这些来自不同蓝牙外设300的第一蓝牙信号区分开。其中，物理地址可以是MAC地址等，在此不作限定。
另外，第一电子设备100在接收到第一蓝牙信号后，记录位置信息以及接收到第一蓝牙信号的时刻(即第一类型的扫描记录)。如此，可以针对第一蓝牙信号携带的物理地址 创建一个对应的第一数据表，并将每次记录的位置信息和接收到第一蓝牙信号的时刻插入第一数据表中。可见，在第一数据表中，第一类型的扫描记录的集合即蓝牙外设300的移动轨迹(即第一数据表可以理解为蓝牙外设300的轨迹list)。
示例性的，上述第一数据表可以是hashtable表，即哈希表。其中，在哈希表中可以以蓝牙外设300的物理地址为hashtable表的“key”，记录的位置信息和时刻为hashtable表的“value”。其中，第一数据表的具体内容可以如下表1所示。

另外，本申请实施例中，第一类型的扫描记录还可以以其他方式存储。例如，第一类型的扫描记录以数据队列的方式存储，在此不作限定。
另外，上述接收第一蓝牙信号的方式，在不漏接蓝牙外设300广播的物理地址的前提下，可以减小第一电子设备100的蓝牙模块工作的时间，从而降低第一电子设备100的能耗。示例性的，在预设时长为6s时，接收第一蓝牙信号的周期可以设定为4秒。
需要说明的是，记录的位置信息可以为基站标识。第一电子设备100在移动的过程中，可以持续获取到在一定距离范围内的基站广播的通信信号。其中，基站广播的通信信号携带有基站标识。基站标识可以用于指示基站的地理位置，如此，记录的位置信息可以为基站标识。
示例性地，获取基站标识的方式包括但不限于以下两种：
第一种：第一电子设备100可以主动搜索基站，并记录搜索到的基站的基站标识作为第一位置信息。在一些可能的实施例中，第一电子设备100可以搜索到多个基站，相应的可以获得多个基站标识，例如获得cellID1，cellID2，cellID3。当搜索到多个基站时，第一电子设备100可以获取其中信号强度最强的基站的基站标识。示例性的，第一电子设备100可以通过图5所示的移动通信模块主动搜索基站。
第二种：第一电子设备100可以获取第一电子设备100正在驻留的基站的基站标识。示例性的，第一电子设备100可以通过图5所示的移动通信模块的监听接口(phonelistener)读取第一电子设备100正在驻留的基站的基站标识。
S406：第一电子设备100检测第一电子设备100的运动状态是否发生变化，如果是，则执行S407。
其中，第一电子设备100检测运动状态的方式可以为：基于运动状态监听器获取目标信息。其中，目标信息为指示第一电子设备100的运动状态的信息。
可以理解地，在第一电子设备100被用户携带时，第一电子设备100的运动状态随着用户的运动状态变化。其中，运动状态可以分为多种。例如，运动状态包括静止状态、步行状态、跑步状态、驾车状态、以及高铁状态等，在此不作限定。
在一些实施例中，目标信息可以包括第一电子设备100的移动速度。具体地，第一电 子设备100检测运动状态的方式可以为：第一电子设备100基于运动状态监听器检测第一电子设备100的移动速度。若第一电子设备100检测到移动速度处于第一预设区间(如[0m/s，0.2m/s])保持一定时长(如2min、3min等)，则确定处于静止状态。若第一电子设备100检测到移动速度处于第二预设区间(如[0.5m/s，3m/s])保持一定时长，则确定处于步行状态。若第一电子设备100检测到移动速度处于第三预设区间如((3m/s，10m/s])保持一定时长，则确定处于跑步状态。若第一电子设备100检测到移动速度处于第四预设区间(如[(10m/s，33m/s)]保持一定时长，则确定处于驾车状态。若第一电子设备100检测移动速度处于第五预设区间(如[34m/s，111m/s])保持一定时长，则确定处于高铁状态。
如此，第一电子设备100可以在检测到移动速度在一定时长内从其中一个预设区间切换到另一个预设区间，并保持预设时长的情况下，确定第一电子设备100的运动状态发生变化。例如，第一电子设备100检测到移动速度从第一预设区间切换到第二预设区间并保持2min的情况下，确定第一电子设备100从静止状态切换到步行状态。再例如，第一电子设备100检测到移动速度在一定时长内从第二预设区间切换到第三预设区间并保持2min的情况下，确定第一电子设备100从步行状态切换到跑步状态。
在另一些实施方式中，目标信息还可以包括第一电子设备100的位姿参数。第一电子设备100检测运动状态的方式还可以为：第一电子设备100基于运动状态监听器监听位姿参数。进而，第一电子设备100将位姿参数输入到预训练的运动状态识别模型中，以使运动状态识别模型基于位姿参数输出运动状态。
在另一些实施方式中，在上述的S403也可以省略。例如，目标信息还可以是应用程序中记录的行程信息。如此，第一电子设备100检测运动状态的方式还可以为：第一电子设备100根据在应用程序中记录的行程信息，确定用户的运动状态。例如，用户在车票购买应用购买了一张目标时段的高铁票(即记录的行程信息)。如此，第一电子设备100在当前时刻处于目标时段时，确定用户处于乘坐高铁状态(即目标运动状态)。再例如，用户在短信应用或即时聊天应用中的消息记录包括“用户在目标时段乘坐高铁”。如此，第一电子设备100在当前时刻处于目标时段时，确定用户处于乘坐高铁状态。再例如，用户在日历应用记录了行程：用户在目标时段乘坐高铁。如此，第一电子设备100在当前时刻处于目标时段时，确定用户处于乘坐高铁状态。
为了进一步准确地确定用户处于乘坐高铁状态的可靠性，第一电子设备100还可以获取在目标时段时，第一电子设备100的位置信息(如GPS定位)。若位置信息在高铁沿线时，则第一电子设备100才确定用户处于乘坐高铁状态。
S407：第一电子设备100查询之前的预设时长内，是否存在第一类型的扫描记录，如果是，则执行S408。
可以理解地，第一电子设备100查询之前的预设时长内，是否存在第一类型的扫描记录，即第一电子设备100确定之前的预设时长内是否扫描到第一蓝牙信号的一种实现方式。若之前的预设时长内存在第一类型的扫描记录，说明在之前的预设时长内扫描到第一蓝牙信号。即是说，第一电子设备100的运动状态发生变化后，具有蓝牙外设300伴随。
S408：第一电子设备100生成第二类型的扫描记录。其中，第二类型的扫描记录与第一蓝牙信号携带的物理地址存在对应关系。
其中，第二类型的扫描记录的内容可以包括：第一电子设备100的运动状态、查询 到的蓝牙外设300的位置信息以及接收到第一蓝牙信号的时刻。
S409：第一电子设备100查询是否存在与第一蓝牙信号携带的物理地址对应的第二数据表，如果否，则执行S410；如果是，则执行S411。
S410：第一电子设备100构建第二数据表。其中，第二数据表用于存储第二类型的扫描记录。进而，第一电子设备100执行S411。
类似地，为了区分不同蓝牙外设300对应的第二类型的扫描记录，可以针对这个第一数据表中的物理地址(即在之前的预设时长内接收到的第一蓝牙信号携带的物理地址)，创建一个对应的用于存储第二类型的扫描记录的第二数据表。可以理解地，在之前的预设时长内接收到的第一蓝牙信号携带的物理地址，和第二类型的扫描记录存在对应关系。
S411：第一电子设备100将生成的第二类型的扫描记录，插入到第二数据表中。
在第二数据表中，第一蓝牙信号携带的物理地址与插入的第二类型的扫描记录存在对应关系。如此，可以通过第二数据表区分接收到的不同的蓝牙外设广播的第一蓝牙信号时，生成的第二类型的扫描记录。
示例性地，第二数据表也可以为哈希表。如此，上述的第二数据表以第一蓝牙信号携带的物理地址为“key”，之前的预设时长内接收到的第一蓝牙信号的时刻、第一电子设备100的位置信息以及变化后的运动状态构成的item(即第二类型的扫描记录)作为“value”。其中，第二数据表的内容可以如下表2所示。
Figure PCTCN2022091338-appb-000003
表2
另外，本申请实施例中，第二类型的扫描记录还可以以其他方式存储。例如，第二类型的扫描记录以数据队列的方式存储，在此不作限定。
S412：第一电子设备100判断与第一蓝牙信号携带的物理地址对应的第二类型的扫描记录的数量是否大于第一阈值，如果是，则执行S413；如果否，则返回执行S406。
可以理解地，由于第二类型的扫描记录是第一电子设备100每发生一次运动状态变化后生成的，说明第二类型的扫描记录的数量即第一电子设备100的运动状态发生变化的次数。如此，第一电子设备100可以遍历第二数据表中的第二类型的扫描记录。若遍历到的第二类型的扫描记录的数量大于预设的阈值(如2次、4次、6次以及8次等)时，说明第一电子设备100在大于预设的阈值个数(如大于或等于3个)的运动状态下，均被蓝牙外设300的伴随，更符合第一电子设备100被蓝牙外设300跟踪的规律。
S413：第一电子设备100判断第二类型的扫描记录的集合中包括位置信息的集合指示的距离是否大于预设的距离阈值，如果是，则执行S414；如果否，则返回执行S406。
可以理解地，第二类型的扫描记录的集合中包括位置信息的集合指示的距离越长时， 第一电子设备100被蓝牙外设300伴随的距离也更长。如此，在第二类型的扫描记录的集合中包括位置信息的集合指示的距离大于预设的距离阈值的情况下，进一步符合第一电子设备100被蓝牙外设300跟踪的规律。
仍以记录的位置信息为基站标识为例，说明如何确定第二类型的扫描记录的集合中包括位置信息的集合指示的距离是否大于预设的距离阈值。
示例性地，在第二类型的扫描记录的集合中包括的基站标识的数量大于预设的第二阈值(如8个)时，说明在第二类型的扫描记录的集合中包括位置信息的集合指示的距离是否大于预设的距离阈值。
S414：第一电子设备100判断第二类型的扫描记录的集合中包括时刻的集合指示的时长是否大于预设的时长阈值，如果是，则执行S415，如果否，则返回执行S406。
示例性地，第一电子设备100可以将第二类型的扫描记录的集合中记录的最晚的时刻减去最早的时刻，得到第二类型的扫描记录的集合中包括时刻的集合指示的时长。
可以理解地，第二类型的扫描记录的集合中包括时刻的集合指示的时长越长时，第一电子设备100被蓝牙外设300伴随的时长也更长。如此，在第二类型的扫描记录的集合中包括时刻的集合指示的时长大于预设的时长阈值的情况下，进一步符合第一电子设备100被蓝牙外设300跟踪的规律。如此，第一电子设备100确定被蓝牙外设300跟踪。这样，结合上述的3个条件，确定被蓝牙外设300跟踪的可靠性更高。
可以理解地，上述的S412、S413以及S414之间没有先后顺序，且S413和S414可以省略。
当S413和S414省略时，下面，结合具体应用场景说明第一电子设备100如何确定被跟踪。
如图10所示，携带有手提包204的用户A准备去乘坐公交车。用户A从起点开始向公交车站步行出发时，第一电子设备100检测到用户A从静止状态处于步行状态(即运动状态发生变化)，此时若第一电子设备100检测到之前预设时长内存在第一类型的扫描记录，则生成一条第二类型的扫描记录(即第一电子设备100确定在步行状态被蓝牙外设300伴随)。当用户A步行到达公交车站时，用户A等待公交车，此时第一电子设备100检测到用户A从步行状态切换为静止状态(即运动状态发生变化)。此时若第一电子设备100预设时长内存在第一类型的扫描记录，则又生成一条第二类型的扫描记录(即第一电子设备100确定在静止状态被蓝牙外设300伴随)。当公交车到站，用户A开始乘坐公交车后，第一电子设备100检测到用户A从静止状态切换为乘车状态，此时若第一电子设备100预设时长内存在第一类型的扫描记录，则生成一条第二类型的扫描记录(即第一电子设备100确定在乘坐状态被蓝牙外设300伴随)。进而，第一电子设备100检测到第二类型的扫描记录的数量大于预设的阈值(如2个)，则确定第一电子设备100被蓝牙外设300跟踪。
可见，在上述的不同时刻的3种状态下，第一电子设备100均确定被蓝牙外设300伴随，即被蓝牙外设300伴随用户的运动状态变化而变化，可以理解为“物随人动”，更符合第一电子设备100被蓝牙外设300跟踪的逻辑常识。如此，第一电子设备100确定被蓝牙外设300跟踪，准确度高。例如，用户A的第一电子设备100不会确定被同乘一辆公交车的用户B携带的蓝牙外设300跟踪；或者，用户A的第一电子设备100不会确定被坐 一起喝咖啡的用户B携带的蓝牙外设300跟踪等，在此不作限定。
S415：第一电子设备100显示提示信息，用于提示用户被蓝牙外设300跟踪。
在一些实施例中，当需要提示用户时，第一电子设备100可以在显示屏顶部弹出一条第一通知，此时用户可以从显示屏顶部下拉出消息通知栏以查看提示消息。
如图11中的(a)所示，第一电子设备100显示操作系统桌面801。第一电子设备100在操作系统桌面801的导航栏显示第一通知802“新来一条跟踪提示，点击查看”。第一电子设备100响应于用户对导航栏的下拉操作，显示通知栏803。如图11中的(b)所示，通知栏803包括提示消息的内容“检测到蓝牙外设在您附近”。如此，即可提示用户被蓝牙外设300跟踪。如此，用户仅需对导航栏输入下拉操作，即可感知到提示信息，方便快捷。
另外，提示信息的内容可以包括：正在跟踪的蓝牙外设300最近一次广播的第一蓝牙信号携带的物理地址(例如可以是蓝牙外设300的MAC地址)，正在跟踪的蓝牙外设300和第一电子设备100的距离(附图中未示)。其中，正在跟踪的蓝牙外设300和第一电子设备100的距离可以根据蓝牙外设300发出的第一蓝牙信号的RSSI数据计算得到。
S416：第一电子设备100响应于用户对提示信息的触发操作，向蓝牙外设300发送控制指令。
如图12所示，提示信息还可以包括第二控件804，第二控件804用于指示蓝牙外设300执行提示操作。第一电子设备100还可以响应于用户对第二控件804的触发操作，与蓝牙外设300建立蓝牙连接。进而，仍如图12所示，第一电子设备100可以向蓝牙外设300发送控制指令。
S417：蓝牙外设300响应于提示指令，执行提示的功能。
蓝牙外设300在接收到控制指令后发出声音或振动(即执行提示的功能)，以方便用户找到蓝牙外设300。
在上述的实施例中，是以第一电子设备100显示提示信息为例说明，第一电子设备100执行提示的功能的。在另一些实施例中，第一电子设备100执行提示的功能还可以是但不限于如下两种实施方式：
第一种：若第一电子设备100检测出被蓝牙外设300跟踪时，若第一电子设备100处于休眠状态(即用户未使用第一电子设备100)，则第一电子设备100可以通过第一电子设备100的一个或多个部件输出提示信息。例如，第一电子设备100触发第一电子设备100的马达开始震动，或者通过第一电子设备100的扬声器输出提示音，或者控制第一电子设备100的一个或多个提示灯闪烁。扬声器输出的提示音，可以是预先设定的铃声，也可以是一段第一电子设备100合成的提示语音。
第二种：当用户佩戴有一个或多个可穿戴设备，并且这些可穿戴设备和第一电子设备100已建立通信连接，那么第一电子设备100可以向这些通信连接的可穿戴设备发送提示信息，触发可穿戴设备执行相应的动作来提示用户。例如，如图13所示，当第一电子设备100和用户佩戴在手腕上的手环1001(即可穿戴设备)通信连接时，第一电子设备100向手环1001发送提示信息，然后手环1001响应提示信息，开始震动并发出提示音。
另外，当第一电子设备100在满足预设条件时，停止接收第一蓝牙信号。例如，第一电子设备100在关机时，停止接收第一蓝牙信号。再例如，第一电子设备100还可以响 应于用户对图9中的第一控件604的关闭操作，关闭预设模式。如此，停止接收第一蓝牙信号。
另外，从在上述的实施例中S402-S408可知，在上述的实施例中是以第一电子设备100持续接收蓝牙外设300广播的第一蓝牙信号为例说明的。在另一些实施例中，如图14所示，上述的S402-S408还可以替换为：
S1101：第一电子设备100注册运动状态监听器，并基于运动状态监听器检测运动状态。
S1102：第一电子设备100检测运动状态是否发生变化，如果是，则执行S1103；如果否，则返回执行S1101。
其中，S1101中的检测运动状态的过程，与上述的S406中的检测运动状态的过程相同，在此不赘述。
S1103：第一电子设备100构造第一信号过滤器。
其中，S1103中的构造第一信号过滤器的过程，也与上述的S402中构造第一信号过滤器的过程相同，在此不再赘述。另外，S1003可以省略。
S1104：第一电子设备100根据第一信号过滤器检测之后的预设时长内是否接收到第一蓝牙信号，如果是，则执行S1105。
示例性，第一电子设备100可以设置一个预设时长的定时器。进而，第一电子设备100在构造第一信号过滤器完毕后，启动定时器计时，并根据第一信号过滤器接收第一蓝牙信号。在预设时长后第一电子设备100计时完毕，停止接收第一蓝牙信号。可见，第一电子设备100仅在定时器的计时期间，接收蓝牙外设300广播的第一蓝牙信号，可以节省功耗。
通常地，蓝牙外设300广播第一蓝牙信号的间隔一般为6秒。为了使得在预设时长内能够接收到至少一个第一蓝牙信号，预设时长可以设置为18秒。
S1105：第一电子设备100生成第一类型的扫描记录，第一类型的扫描记录与第一蓝牙信号携带的物理地址存在对应关系。
其中，S1105的原理与上述的S405的原理相同，在此不作赘述。
S1106：第一电子设备100生成第二类型的扫描记录。其中，第二类型的扫描记录与第一蓝牙信号携带的物理地址存在对应关系。
其中，S1106中生成第二类型的扫描记录的原理，与上述的S408中生成第二类型的扫描记录的原理相同，在此不再赘述。
另外，在上述实施例中的S402之前，该设备跟踪检测方法还可以包括：
第一电子设备100构造第二信号过滤器。第二信号过滤器的构造方式可以为：第一电子设备获取蓝牙信号的服务数据和对应的厂商数据(manufacturerID)，然后将蓝牙信号的服务数据和厂商数据作为输入参数输入过滤器构造函数，就可以获得由过滤器构造函数构造好的第二信号过滤器。第二信号过滤器可以是nearby过滤器。
进而，第一电子设备100判断基于第二信号过滤器是否能接收到第二电子设备广播的第二蓝牙信号，如果是，才执行S402。
由上述介绍的蓝牙外设300的工作原理可知，在第一电子设备100基于第二信号过滤器能够接收到附近的第二电子设备广播的第二蓝牙信号时，第一电子设备100的位置信息 (即用户的位置)才可能泄露给他人。如此，可以在接收到第二电子设备广播的第二蓝牙信号的情况下，才执行后续的步骤，这样可以节省第一电子设备100的功耗。
另外，在上述的实施例中，是以蓝牙外设300的位置信息为基站的标识为例说明的。在另一些实施例中，蓝牙外设300的位置信息还可以为无线网络标识、地理坐标等，在此不作限定。
其中，获取无线网络标识的方式可以为：第一电子设备100搜索无线局域网(Wifi)并记录搜索到的无线局域网的网络标识(WifiID)，将搜索得到的网络标识确定为第一电子设备100的位置信息，若搜索到多个无线局域网，第一电子设备100可以选择其中信号强度最高的网络标识作为第一电子设备100的位置信息。示例性的，第一电子设备100可以调用图5所示的无线通信模块搜索无线局域网。
或者，第一电子设备100读取第一电子设备100当前接入的无线局域网的网络标识，将读取的网络标识确定为第一电子设备100的位置信息。示例性的，第一电子设备100可以从图5所示的无线通信模块读取第一电子设备100当前接入的无线局域网的网络标识。
另外，获取地理坐标的方式可以为：第一电子设备100可以通过GPS定位模块采集的地理坐标，然后给第一电子设备100将采集到的地理坐标作为第一电子设备100的位置信息。
