Abstract

一种设备跟踪检测方法，涉及终端技术领域。由于第一电子设备(100)在基于第一信号过滤器接收到第一蓝牙信号时，说明第一蓝牙外设(300)在第一电子设备(100)附近；而又由于第一蓝牙外设(300)每隔第二时长才广播一次第一蓝牙信号，说明第一蓝牙外设(300)基于第一信号过滤器接收到第一蓝牙信号的第二时长内，也可能在第一电子设备(100)附近。这样一来，在移动速度大于预设的速度阈值时，记录的第一蓝牙外设(300)的轨迹信息中不仅包括第一电子设备(100)接收到第一蓝牙信号时的位置信息，还包括第二时长内第一电子设备(100)的位置信息。进而，第一电子设备(100)得到的第一蓝牙外设(300)的轨迹信息的内容更丰富，可靠性更高。

技术领域
本申请涉及终端技术领域，尤其涉及一种设备跟踪检测方法和电子设备。
背景技术
随着蓝牙技术的发展，有的蓝牙外设可以用于定位物品。例如，用户可以将第一蓝牙外设与随身携带的物品(如钥匙、背包等)放在一起。用户可以获取第一蓝牙外设的位置信息(即物品的位置信息)，来定位物品。
在某些情况下，用户B可能会将上述第一蓝牙外设放在用户A随身携带的物品中。由于用户B可以获取第一蓝牙外设的位置信息，这样一来，用户B可以根据该第一蓝牙外设跟踪用户A。
如此，为了避免被第一蓝牙外设跟踪，用户A可以利用电子设备检测出随身携带的物品中的第一蓝牙外设。然而，在第一蓝牙外设和电子设备处于高速移动的状态下，电子设备检测出随身携带的物品中的第一蓝牙外设的准确度低。
发明内容

第一方面，本申请提供了一种设备跟踪检测方法，包括：应用于第一电子设备，第一电子设备包括目标模块，目标模块用于缓存第一电子设备正处于的位置的位置信息。本申请提供的方法包括：第一电子设备从目标模块获取位置信息，并记录获取到的位置信息为第一电子设备的位置信息。其中，第一电子设备的位置信息的集合为第一轨迹信息。第一电子设备在基于第一信号过滤器接收到第一蓝牙信号时，从目标模块获取位置信息。第一电子设备记录在接收到第一蓝牙信号的时刻获取的位置信息，为第一蓝牙外设的位置信息，其中，第一蓝牙外设的位置信息的集合为第二轨迹信息。第一电子设备确定是否处于目标状态，目标状态为在移动速度大于预设的速度阈值的状态。在第一电子设备处于目标状态时，从第一轨迹信息中获取第二时长内的位置信息，第二时长的终止时刻为第一电子设备接收到第一蓝牙信号的时刻，第二时长为第一蓝牙外设广播第一蓝牙信号的周期时长。第一电子设备将获取的第二时长内的位置信息，插入第二轨迹信息中以更新第二轨迹信息。 在第一轨迹信息和更新后的第二轨迹信息相似度大于预设的相似度阈值的情况下，第一电子设备提示用户被第一蓝牙外设跟踪。
本申请提供的设备跟踪检测方法，由于第一电子设备在基于第一信号过滤器接收到第一蓝牙信号时，说明第一蓝牙外设在第一电子设备附近；而又由于第一蓝牙外设每隔第二时长才广播一次第一蓝牙信号，说明第一蓝牙外设基于第一信号过滤器接收到第一蓝牙信号的第二时长内，也可能在第一电子设备附近。

在一种可能的实施方式中，在第一电子设备从目标模块获取位置信息，并记录获取到的位置信息为第一电子设备的位置信息之前，本申请提供的方法还包括：第一电子设备基于第二信号过滤器接收到第二电子设备广播的第二蓝牙信号。
可以理解地，在第一电子设备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，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，才执行后续的设备跟踪检测步骤，这样可以节省第一电子设备的功耗。

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。
随着蓝牙技术的发展，有的蓝牙外设可以用于定位物品。例如，用户可以将第一蓝牙外设与随身携带的物品(如钥匙、背包等)放在一起。用户可以获取第一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，手机400可以与第一蓝牙外设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400查找第一蓝牙外设300所在的位置，来定位与第一蓝牙外设300放在一起的物品。
一方面，仍如图1所示，在手机400仍与第一蓝牙外设300保持连接的情况下，手机400可以接收到第一蓝牙外设300广播的第一蓝牙信号。进而，手机400在被用户触发查找的功能后，根据第一蓝牙信号检测第一蓝牙外设300的位置信息。进而，手机400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400还可以响应于用户对声控按钮202的触发操作，控制第一蓝牙外设300发声，以协助用户寻找与第一蓝牙外设300放在一起的物品。
在另一方面，当手机400与第一蓝牙外设300断开连接的情况下，与第一蓝牙外设300在预设距离范围内的电子设备可以接收到第一蓝牙外设广播的第一蓝牙信号。进而，电子设备可以向云服务器发送电子设备的位置信息。手机400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，手机400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。由于电子设备与第一蓝牙外设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第一蓝牙外设300的位置，以方便找回遗失的物品。
然而，针对第一蓝牙外设的应用存在一定的安全隐患，即用户可能将此类第一蓝牙外设用于跟踪其他用户。比如，若用户B将其第一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第一蓝牙外设移动。由此，用户B可以从云服务器查询到与第一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，推测出第一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的第一蓝牙外设。
有鉴于此，本申请所提供的设备跟踪检测方法，第一电子设备记录在接收到所述第一蓝牙信号的时刻获取的位置信息，为第一蓝牙外设的位置信息。可以理解地，第一蓝牙外设的位置信息的集合为第二轨迹信息。在第一电子设备处于目标状态(即高速移动的状态)时，从第一轨迹信息中获取第二时长内的位置信息，第二时长的终止时刻为第一电子设备接收到第一蓝牙信号的时刻，第二时长为第一蓝牙外设广播第一蓝牙信号的周期时长。第一电子设备将获取的第二时长内的位置信息，插入第二轨迹信息中以更新第二轨迹信息。
这样一来，在移动速度大于预设的速度阈值时，记录的第一蓝牙外设的轨迹信息中不仅包括第一电子设备接收到第一蓝牙信号时的位置信息，还包括接收到第一蓝牙信号之前第二时长内第一电子设备的位置信息，进而得到的第一蓝牙外设的轨迹信息的内容更丰富，可靠性更高。如此，使得基于第一轨迹信息(即第一电子设备的轨迹信息)与第二轨迹(第一蓝牙外设的轨迹信息)，提示被跟踪的可靠性更高。

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。
无线通信模块160可以提供应用在第一电子设备100上的包括无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络)，蓝牙(bluetooth，BT)，全球导航卫星系统(global navigation satellite system，GNSS)，调频(frequency modulation，FM)，近距离无线通信技术(near field communication，NFC)，红外技术(infrared，IR)等无线通信的解决方案。无线通信模块160可以是集成至少一个通信处理模块的一个或多个器件。无线通信模块160经由天线2检测到电磁波，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器110。无线通信模块160还可以从处理器110检测到待发送的信号，对其进行调频，放大，经天线2转为电磁波辐射出去。示例性地，无线通信 模块160可以包括蓝牙模块、Wi-Fi模块等。
在一些实施例中，第一电子设备100的天线1和移动通信模块150耦合，天线2和无线通信模块160耦合，使得第一电子设备100可以通过无线通信技术与网络以及其他设备通信。所述无线通信技术可以包括全球移动通讯系统(global system for mobile communications，GSM)，通用分组无线服务(general packet radio service，GPRS)，码分多址接入(code division multiple access，CDMA)，宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)，BT，GNSS，WLAN，NFC，FM，和/或IR技术等。所述GNSS可以包括全球卫星定位系统(global positioning system，GPS)，全球导航卫星系统(global navigation satellite system，GLONASS)，北斗卫星导航系统(beidou navigation satellite system，BDS)，准天顶卫星系统(quasi-zenith satellite system，QZSS)和/或星基增强系统(satellite based augmentation systems，SBAS)。

在一些实施例中，蓝牙模块可以通过周期性地扫描，获得第一蓝牙外设发出的蓝牙信号，然后将第一蓝牙外设发送的蓝牙信号上报给第一电子设备100的处理器110，处理器110收到第一蓝牙外设的蓝牙信号后，向云服务器发送第一电子设备100的位置信息。蓝牙模块收到第一蓝牙外设的蓝牙信号，表明第一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，相当于是第一蓝牙外设的位置信息。
在一些实施例中，处理器110可以给蓝牙控制器配置一个或多个信号过滤器，蓝牙控制器利用从多个信号过滤器中的第一信号过滤器从接收到的蓝牙信号中过滤出第一蓝牙信号，并将过滤出的第一蓝牙信号上报给处理器110，从而触发处理器110记录位置信息。

第一电子设备：可以是用户设备(user equipment，UE)，例如可以为手机、平板电脑、桌面型、膝上型笔记本电脑、手持计算机、上网本、个人数字助理(personal digital assistant，PDA)等设备。另外，第一电子设备还具有接收第一蓝牙信号的功能。

下面，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。
请参考图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。
可以理解地，第一电子设备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，第一控件用于指示开启预设模式。如此，第一电子设备100响应于用户对第一控件的触发操作，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”，即第一控件503用于指示开启预设模式。第一电子设备100可以响应于用户对第一控件503的触发操作，开启预设模式。如此，用户即可在系统桌面501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”，即第一控件604用于指示开启预设模式。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，或者在第一电子设备100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也可以默认开启预设模式。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。
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。如此，第一电子设备100可以基于第一信号过滤器接收第一蓝牙信号。
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。
其中，第一蓝牙信号的特征数据可以包括但不限于第一蓝牙外设的蓝牙外设名，第一蓝牙外设的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可以预先配置有上述的第一信号过滤器，这样一来，上述的S402可以省略。
S403：第一电子设备100构造第二信号过滤器。
其中，S403和S404之间没有先后顺序。
第二信号过滤器的构造方式可以为：第一电子设备100获取第二蓝牙信号的服务数据和对应的厂商数据(manufacturerID)，然后将第二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。示例性地，第二信号过滤器可以是nearby过滤器。
在另一些实施例中，上述第一电子设备100还可以预先配置第二信号过滤器，这样一来，上述的S403可以省略。
S404：第一电子设备100基于第二信号过滤器接收到第二电子设备200广播的第二蓝牙信号。
可以理解地，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200广播的第二蓝牙信号时，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200广播的第二蓝牙信号的情况下，才执行后续的S405-S414介绍的设备跟踪检测步骤，这样可以节省第一电子设备100的功耗。其中，第二电子设备200每隔第一时长(如2s)广播一次第二蓝牙信号。如此，第一电子设备100每隔第一时长能够接收到第二电子设备200广播的第二蓝牙信号。
可选地，在另一些实施例中，上述的S403-S404也可以省略。
可以理解地，上述的S401-S404为实现本申请提供的设备跟踪检测方法的准备步骤。在完成S401-S404后，第一电子设备100即可在被用户随身携带的过程中，实现设备跟踪检测。下面，结合S405-S414说明第一电子设备100如何实现设备跟踪检测。
S405：第一电子设备100从目标模块获取位置信息，并记录获取到的位置信息为第一 电子设备100的位置信息。其中，第一电子设备100的位置信息的集合为第一电子设备100的轨迹信息(即第一轨迹信息)。
目标模块用于缓存第一电子设备100正处于的位置的位置信息。示例性地，目标模块可以为上述的图5中位于第一电子设备100的操作系统的框架层中的通信服务模块(即telephony模块)。其中，位置信息可以包括第一电子设备100正驻留的基站的基站标识(即Cell information)。例如，当第一电子设备100正驻留的基站的基站标识为Cell ID1时，目标模块中缓存的位置信息为Cell ID1；当第一电子设备100驻留的基站的基站标识为Cell ID2时，目标模块中缓存的位置信息从Cell ID1更新为Cell ID2。示例性的，第一电子设备100可以通过图4所示的移动通信模块驻留基站。
如此，第一电子设备100可以将从目标模块获取的位置信息，记录为第一电子设备100的位置信息。另外，由于第一电子设备100每隔第一时长接收到第二电子设备200广播的第二蓝牙信号，这样一来，第一电子设备100也是每隔第一时长从目标模块获取位置信息。其中，获取到的位置信息的集合可以理解为第一电子设备100的轨迹信息(即第一轨迹信息)。可以理解地，第一轨迹信息中记录的相邻两个位置信息的时间间隔为第一时长。
另外，位置信息中还可以包括第一电子设备100采集到基站标识的时刻，以及用于指示基站是否位于高铁沿线的字段等，在此不作限定。
在一些实施方式中，第一电子设备100可以针对第一电子设备100的物理地址创建一个对应的第一数据表。进而，第一电子设备100可以将每次获取的第一电子设备100的位置信息插入第一数据表中。如此，第一电子设备100可以利用第一数据表，记录第一电子设备100的位置信息，方便快捷。可以理解地，第一数据表中的位置信息的集合，即第一电子设备100的轨迹信息。示例性的，上述第一数据表可以是hashtable表，即哈希表。其中，在哈希表中可以以第一电子设备100的物理地址为hashtable表的“key”，记录的第一电子设备100的位置信息为hashtable表的“value”。其中，第一数据表的具体内容可以如下表1所示。
表1
Figure PCTCN2022091339-appb-000003
在表1中字段“1”用于指示基站位于高铁沿线。另外，本申请实施例中，第一电子设备100的位置信息还可以以其他方式存储。例如，第一电子设备100的位置信息以数据队列的方式存储，在此不作限定。
S406：第一电子设备100基于第一信号过滤器接收到第一蓝牙信号。
示例性地，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，即第一蓝牙外设300广播的第一蓝牙信号。
S407：第一电子设备100在接收到第一蓝牙信号时，从目标模块获取位置信息。
可以理解地，由于第一电子设备100在基于第一信号过滤器接收到第一蓝牙信号时，说明第一蓝牙外设300在第一电子设备100附近。如此，第一电子设备100可以在接收到第一蓝牙信号的时刻，从目标模块获取位置信息。可以理解地，第一电子设备100在接收到第一蓝牙信号时，第一蓝牙外设300在第一电子设备100的附近。如此，在接收到第一蓝牙信号的时刻，从目标模块获取的位置信息，可以作为第一蓝牙外设300在接收到第一蓝牙信号的时刻的位置信息。
S408：第一电子设备100记录在接收到第一蓝牙信号的时刻获取的位置信息，为第一蓝牙外设300的位置信息。其中，第一蓝牙外设300的位置信息的集合为第一蓝牙外设300的轨迹信息(即，第二轨迹信息)。
示例性地，第一电子设备100可以根据第一蓝牙外设300的标识(如第一蓝牙外设300的MAC地址)，创建一个对应的用于存储第一蓝牙外设300的位置信息的第二数据表。第一电子设备100将每次在接收到第一蓝牙信号的时刻，从目标模块获取的位置信息，存储在第一蓝牙外设300的标识对应的第二数据表中。如此，第一电子设备100可以利用第二数据表，记录第一蓝牙外设300的位置信息，方便快捷。示例性的，上述第二数据表也可以是hashtable表，即哈希表。其中，在哈希表中可以以第一蓝牙外设300的标识为“key”，第一蓝牙外设300在接收到第一蓝牙信号的时刻的位置信息作为“value”。在这种情况下，第二数据表的内容可以下表2所示。
表2
Figure PCTCN2022091339-appb-000004
S409：第一电子设备100判断是否处于目标状态，如果是，则执行S410。其中，目标状态为第一电子设备100的移动速度大于预设的速度阈值(如25m/s)的状态。
示例性地，第一电子设备100获取目标信息。其中，目标信息为表征第一电子设备100的移动速度的信息。第一电子设备100根据目标信息，检测第一电子设备100是否处于目标状态。
下面，以目标状态为第一电子设备100的移动速率大于第一速度阈值的移动状态为例，说明第一电子设备100如何确定是否处于目标状态的几种方式。可以理解地，第一电子设备100的移动速率大于第一速度阈值(如25m/s)时，第一电子设备100处于被用户携带上高铁的移动状态。
第一种：目标信息为位置信息。第一电子设备100可以识别从目标模块中获取的位置 信息，是否携带有用于指示基站位于高铁沿线的字段(如二进数“1”)，如果是，则第一电子设备100确定处于目标状态；如果否，则第一电子设备100确定未处于目标状态。
第二种：目标信息为移动速度。第一电子设备100检测移动速度。进而，第一电子设备100判断在移动速度是否大于预设的第一速度阈值(如25m/s)，如果是，则第一电子设备100确定处于目标状态；如果否，则第一电子设备100确定未处于目标状态。
第三种：目标信息为应用程序中记录的行程信息，行程信息用于指示用户在目标时段乘坐高铁。在处于目标时段时，第一电子设备100确定处于目标状态；在未处于目标时段时，则第一电子设备100确定未处于目标状态。
例如，用户在车票购买应用购买了一张目标时段的高铁票，则第一电子设备100记录有高铁票的信息(即记录的行程信息)。如此，第一电子设备100在处于目标时段时，确定第一电子设备100处于目标状态。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在处于目标时段时，确定第一电子设备100处于目标状态。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，在处于目标时段时，第一电子设备100确定处于目标状态；在未处于目标时段时，则第一电子设备100确定未处于目标状态。
需要说明的是，确定处于目标状态不仅是上述的3种方式，在此仅仅是举例说明。例如，第一电子设备100还可以将上述的3种方式或任意两种方式结合起来，确定第一电子设备100处于目标状态，可靠性更高。
S410：第一电子设备100判断在的第二时长内，是否记录有第一电子设备100的位置信息，如果是，则执行S411。
需要说明的是，第二时长(如6s)大于上述的第一时长(如2s)，且第二时长的结束时刻为接收到第一蓝牙信号的时刻。第二时长为第一蓝牙外设300广播第一蓝牙信号的周期时长。
示例性地，第一电子设备100可以从上述的第一数据表中，判断的第二时长内是否记录有第一电子设备100的位置信息。
S411：第一电子设备100将第二时长内记录的第一电子设备100的位置信息，插入第一蓝牙外设300的轨迹信息中，以更新第一蓝牙外设300的轨迹信息。
基于上述的对S407的描述，第一电子设备100可以将在第一数据结构中的第二时长内记录的第一电子设备100的位置信息，插入到第二数据表中。此时，第二数据表中记录的位置信息的集合，即第一蓝牙外设300的轨迹信息(即第二轨迹信息)。在这种情况下，第二数据表中的内容可以如下表3所示。
表3
Figure PCTCN2022091339-appb-000005
Figure PCTCN2022091339-appb-000006
在表3中字段“1”用于指示基站位于高铁沿线。可见，表3中的数据内容相对于表2中的数据内容更加丰富、充实，可靠性更高。另外，本申请实施例中，第一电子设备100的位置信息还可以以其他方式存储。例如，第一电子设备100的位置信息以数据队列的方式存储，在此不作限定。
可以理解地，由于第一蓝牙外设300每隔第二时长才广播一次第一蓝牙信号，说明第一蓝牙外设300基于接收到第一蓝牙信号的第二时长内，也可能在第一电子设备100附近。
这样一来，在移动速度大于预设的速度阈值时，第一电子设备100记录的第一蓝牙外设300的轨迹信息中，不仅包括第一电子设备100接收到第一蓝牙信号时，从目标模块获取的位置信息；还包括接收到第一蓝牙信号的第二时长内，第一轨迹信息中的第一电子设备100的位置信息。进而，第一电子设备100得到的第一蓝牙外设300的轨迹信息的内容更丰富，可靠性更高。
下面，以目标状态为第一电子设备100的移动速率大于第一速度阈值的移动状态(即第一电子设备100处于被用户携带上高铁的移动状态)，目标模块缓存的位置信息包括基站标识为例，说明上述的S411。
在第一电子设备100被用户携带上高铁时，第一电子设备100可以先后驻留到在高铁经过的沿线各基站。如此，第一电子设备100的目标模块可以缓存驻留的基站的基站标识。第一电子设备100可以每隔第一时长(如2s)从目标模块获取基站标识。如此，第一电子设备100随着高铁移动的过程中，可以先后从目标模块中获取到高铁经过的沿线每个基站的基站标识。
如图10所示，在一些实施例中，当高铁701在第二时长(如6s)内从位置A行驶到位置B时，经过了5个基站且在每个基站驻留的时间均小于或等于第一时长(如2s)，则第一电子设备100可以从目标模块中获取到5个基站的基站标识。例如，第一电子设备100获取的5个基站标识可以为cellID1，cellID2，cellID3，cellID4，cellID5等，在此不作限定。基站标识的集合(cellID1，cellID2，cellID3，cellID4，cellID5)即可作为第一电子设备100的在第二时长内的轨迹信息。以此类推，第一电子设备100可以得到高铁701在发车后经过的所有基站的基站标识，作为第一电子设备100在高铁701上时的轨迹信息。
仍如图10所示，在另一些实施例中，当高铁701在第二时长(如6s)内从位置A行驶到位置B时，经过了5个基站且在基站标识为cellID2的基站驻留了大于第一时长(如2s)且小于两倍第一时长的时间，例如，第一电子设备100在第二时长内获取的基站标识可以为cellID1，cellID2，cellID2，cellID3，cellID4，cellID5。基站标识的集合(cellID1，cellID2，cellID2，cellID3，cellID4，cellID5)即可作为第一电子设备100的在第二时长内的轨迹信息。
另外，为了节省存储空间以及后续的相似度比对的计算量，第一电子设备100可以在第二时长内获取的基站标识中，相同的基站标识去重，得到基站标识的集合。例如，第一电子设备100可以将获取的基站标识cellID1，cellID2，cellID2，cellID3，cellID4，cellID5中去掉一个“cellID2”，得到基站标识的集合(cellID1，cellID2，cellID2，cellID3，cellID4，cellID5)。
可以理解地，当用户携带包含第一蓝牙外设300的行李包和第一电子设备100乘坐高 铁701时，第一蓝牙外设300每隔第二时长(如6s)可以广播第一蓝牙信号。这样，第一电子设备100每隔第二时长可以基于第一信号过滤器接收到第一蓝牙信号。仍如图10所示，当高铁701行驶到位置B时，第一电子设备100基于第一信号过滤器接收到第一蓝牙信号。在第一电子设备100接收到第一蓝牙信号的时刻，第一电子设备100可以从目标模块中获取到的基站703的基站标识“cellID5”。
可以理解地，由于第一电子设备100在基于第一信号过滤器接收到第一蓝牙信号时，说明第一蓝牙外设300在第一电子设备100附近，如此可以将记录的基站标识“cellID5”作为第一蓝牙外设300的位置信息。
另外，又由于第一蓝牙外设300每隔第二时长才广播一次第一蓝牙信号，而第一蓝牙外设300基于第一信号过滤器接收到第一蓝牙信号的第二时长内，就可能在第一电子设备100附近。而由于第一电子设备100和第一蓝牙外设300均位于高铁701，移动速度大于预设的速度阈值，则第一电子设备100和第一蓝牙外设300可能在第二时长内经过了多个基站，如此，第一电子设备100还可以从第一电子设备100的轨迹信息中，获取第二时长内的基站标识，作为第一蓝牙外设300经过的位置信息。
仍如图10所示，当高铁701行驶到位置B的第二时长内还经过了4个基站，第一电子设备100将在的第二时长内的记录的4个基站的基站标识(cellID1，cellID2，cellID3，cellID4)也作为第一蓝牙外设300经过的位置信息。如此，第一蓝牙外设300在第二时长内的轨迹信息为(cellID1，cellID2，cellID3，cellID4，cellID5)。这样一来，第一电子设备100可以填补漏记录的第一蓝牙外设300的位置信息。进而，第一电子设备100得到的第一蓝牙外设300在位于高铁701的轨迹信息的内容更丰富，可靠性更高。
可以理解地，当第一电子设备100下一次接收到第一蓝牙信号时，也可以将接收到第一蓝牙信号的第二时长内，第一轨迹信息中的第一电子设备100的基站标识，填补漏记录的第一蓝牙外设300的位置信息，如此循环，直到第一电子设备100确定未处于目标状态。
S412：第一电子设备100在满足预设条件的情况下，判断第一电子设备100的轨迹信息和更新后的第一蓝牙外设300的轨迹信息的相似度，是否大于预设的相似度阈值，如果是，则执行S413。
其中，上述的预设条件可以为第一电子设备100的屏幕被触发点亮，或者，第一电子设备100的记录的第一蓝牙外设300的轨迹信息大于预设的距离阈值等，在此不作限定。
在一些实施方式中，第一电子设备100计算第一电子设备100的轨迹信息(即第一轨迹信息)和更新后的第一蓝牙外设300的轨迹信息(即第二轨迹信息)的相似度方式可以为：
第一电子设备100基于算式
Figure PCTCN2022091339-appb-000007
计算第一电子设备100的轨迹信息和更新后的第一蓝牙外设300的轨迹信息的相似度。其中，N1为更新后的第一蓝牙外设300的轨迹信息中的基站标识的个数，N2为第一电子设备100的轨迹信息的基站标识的个数，S为第一电子设备100的轨迹信息和更新后的第一蓝牙外设300的轨迹信息的相似度。
可以理解地，基于上述的对图10的介绍可知，第一电子设备100的轨迹信息可以包括相同的基站标识，即第一电子设备100的位置信息的集合未去重；类似地，第一蓝牙外 设300的轨迹信息也可能包括相同的基站标识，即第一蓝牙外设300的位置信息的集合未去重。
或者，第一电子设备100的轨迹信息包括的基站标识各不相同，即第一电子设备100的位置信息的集合被去重；类似地，第一蓝牙外设300的轨迹信息包括的基站标识也各不相同，即第一蓝牙外设300的位置信息的集合也被去重。当第一电子设备100的位置信息的集合被去重，以及第一蓝牙外设300的位置信息的集合也被去重，可以减少计算量，节省计算资源。
另外，预设的相似度阈值可以为60％、70％、以及80％等，在此不作限定。
在一些应用场景中，若预设的阈值为60％，且第一电子设备100的轨迹信息和更新后的第一蓝牙外设300的轨迹信息均是在处于高铁701的移动状态下记录的。当用户未携带第一电子设备100远离座位上的行李包时，第一电子设备100每隔第二时长都能够通过第一信号过滤器，接收到行李包内的第一蓝牙外设300的第一蓝牙信号。这样一来，由上述的S405-S411涉及的方案可知，在第一电子设备100不漏接收第一蓝牙信号的情况下，记录的第一电子设备100的轨迹信息与更新后的第一蓝牙外设300的轨迹信息相同，即计算得出的相似度为1。可见，第一电子设备100的轨迹信息与更新后的第一蓝牙外设300的轨迹信息大于预设的相似度阈值60％。
可见，在第一电子设备100未远离第一蓝牙外设300的情况下，记录的第一电子设备100轨迹信息与第一蓝牙外设300的轨迹信息相同。
在另一些应用场景中，若预设的阈值为60％，且第一电子设备100的轨迹信息和更新后的第一蓝牙外设300的轨迹信息均是在处于高铁701的移动状态下得到的。当用户携带第一电子设备100远离座位上的行李包300s(大于预设的时长)时(如用户携带第一电子设备100远离座位上洗手间、或打水等行为)，第一电子设备100在离开的300s不能够接收到第一蓝牙外设300广播的第一蓝牙信号。如此，这样一来，由上述的S405-S411涉及的方案可知，这段时长(即上述的300s)内第一电子设备100从目标模块获取的基站标识，不会作为更新后的第一蓝牙外设300的轨迹信息的一部分。而用户携带第一电子设备100回到座位后，第一电子设备100每隔第二时长又能够接收到第一蓝牙外设300广播的蓝牙信号。如此，第一电子设备100又会将接收到第一蓝牙信号的时刻，从目标模块获取的基站标识的集合，以及第一数据结构中的第二时长内记录的位置信息，作为更新后的第一蓝牙外设300的轨迹信息的一部分。
假设高铁701从起点开始至到达终点停靠后，总共经历了2700个基站，则第一电子设备100记录的第一电子设备100轨迹信息中包括2700个基站标识。而在上述第一电子设备100远离座位上的行李包300s内，第一电子设备100记录的基站标识包括300个基站标识。如此，第一电子设备100记录的第一蓝牙外设300的轨迹信息包括2400个基站标识。进而，第一电子设备100计算得到的相似度
Figure PCTCN2022091339-appb-000008
可见，第一电子设备100轨迹信息与更新后的第一蓝牙外设300的轨迹信息大于预设的相似度阈值60％。进而，即第一电子设备100可以确定被第一蓝牙外设300跟踪。
在另一些应用场景中，若预设的阈值为60％，且第一电子设备100的轨迹信息和更新 后的第一蓝牙外设300的轨迹信息均是在处于高铁701的移动状态下得到的。当用户A携带第一电子设备100开始乘坐高铁时，位于用户A的邻座的用户B的行李包内包含第一蓝牙外设300。此时，第一电子设备100每间隔第二时长都能够接收到第一蓝牙外设300广播的第一蓝牙信号。若在高铁701从起点开始行驶到中途停靠站C时，经历了1500个基站，这样一来，由上述的S405-S411涉及的方案可知，第一电子设备100从目标模块获取的1500个基站标识，可以作为更新后的第一蓝牙外设300的轨迹信息。而若用户B携带包含第一蓝牙外设300的行李包在中途停靠站C下车后，从中途停靠站C开始至高铁到达终点，第一电子设备100不能够接收到第一蓝牙外设300广播的第一蓝牙信号。如此，从中途停靠站C开始至高铁到达终点，第一电子设备100从目标模块获取的基站标识不能够再作为更新后的第一蓝牙外设300的轨迹信息的一部分。
假设高铁701从起点开始至到达终点停靠后，总共经历了2700个基站，则第一电子设备100记录的第一电子设备100的轨迹信息中包括2700个基站标识，而记录的更新后的第一蓝牙外设300的轨迹信息包括1500个基站标识。进而，第一电子设备100计算得到的相似度
Figure PCTCN2022091339-appb-000009
可见，第一电子设备100轨迹信息与第一蓝牙外设300的轨迹信息小于预设的相似度阈值60％。即第一电子设备100可以确定未被第一蓝牙外设300跟踪。
S413：第一电子设备100显示提示信息，用于提示用户被第一蓝牙外设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提示消息，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显示系统桌面801。第一电子设备100在系统桌面801的导航栏显示提示信息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802的内容“检测到蓝牙外设在您附近”。如此，即可提示用户被第一蓝牙外设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，提示信息内容还可以包括：正在跟踪的第一蓝牙外设300最近一次发出的蓝牙信号所携带的物理地址(例如可以是第一蓝牙外设300的MAC地址)，正在跟踪的第一蓝牙外设300和第一电子设备100的距离(附图中未示)。其中，正在跟踪的第一蓝牙外设300和第一电子设备100的距离，第一电子设备100可以根据第一蓝牙外设300发出的第一蓝牙信号的RSSI数据计算得到。
S414：第一电子设备100响应于用户对提示信息的触发操作，向第一蓝牙外设300发送控制指令。
S415：第一蓝牙外设300响应于提示指令，执行提示的功能。
如图12所示，通知栏803还可以包括第二控件804，第一控件804用于指示第一蓝牙外设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，与第一蓝牙外设300建立蓝牙连接。进而，仍如图12所示，第一电子设备100可以向第一蓝牙外设300发送控制指令。第一蓝牙外设300在接收到控制指令后发出声音或振 动，以方便用户找到第一蓝牙外设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检测出被第一蓝牙外设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，第一电子设备100停止接收第一蓝牙信号。
可以理解地，在上述的实施例中，由S405-S411可知，在第一电子设备100处于目标状态之前(如第一电子设备100被步行的用户携带)，第一电子设备100也可以从目标模块获取位置信息。其中，在第一电子设备100处于目标状态之前从目标模块获取的位置信息的集合可以作为第一电子设备100的轨迹信息的一部分。在第一电子设备100处于目标状态之后(如用户步行上了高铁)，第一电子设备100从目标模块获取的位置信息的集合可以作为第一电子设备100的轨迹信息的另一部分。即，在第一电子设备100的轨迹信息可以包括第一电子设备100处于目标状态之前从目标模块获取的位置信息，以及第一电子设备100处于目标状态之后从目标模块获取的位置信息。
类似地，仍由S405-S411可知，第一电子设备100处于目标状态之前(如第一电子设备100被步行的用户携带)，第一电子设备100可以将在接收到第一蓝牙外设300广播的第一蓝牙信号的时刻，从目标模块获取的位置信息，记录为第一蓝牙外设300的轨迹信息的一部分。在第一电子设备100处于目标状态之后(如携带第一电子设备100的用户步行上了高铁)，第一电子设备100可以将接收到第一蓝牙外设300广播的第一蓝牙信号的时刻从目标模块获取的位置信息，以及在的第二时长内第一电子设备的轨迹信息中的位置信息，记录第一蓝牙外设300的轨迹信息的另一部分。即，第一蓝牙外设300的轨迹信息包括第一电子设备100处于目标状态之前，记录为第一蓝牙外设300的轨迹信息的一部分，以及第一电子设备100处于目标状态之后，记录第一蓝牙外设300的轨迹信息的另一部分。
可以理解地，基于与上述的S411同样的原理，由于第一蓝牙外设300的轨迹信息中，包括了在第一电子设备100处于目标状态之后，第一蓝牙外设300的部分轨迹信息。而在由于第一蓝牙外设300的轨迹信息中，包括了在第一电子设备100处于目标状态之后，第 一蓝牙外设300的部分轨迹信息，填补了漏记录的第一蓝牙外设300的位置信息，进而整个得到的第一蓝牙外设300的轨迹信息的内容丰富，可靠性高。在这种情况下，第一电子设备100基于第一电子设备100的轨迹信息和第一蓝牙外设300的轨迹信息，提示第一蓝牙外设300被跟踪的可靠性也高。
另外，在上述的实施例中，是以第一电子设备100的轨迹信息和第一蓝牙外设300的轨迹信息中的位置信息为基站标识为例说明的。在另一些实施例中，第一电子设备100的轨迹信息和第一蓝牙外设300的轨迹信息中的位置信息还可以为但不限于GPS定位信息。如此，计算第一电子设备100的轨迹信息和第一蓝牙外设300的轨迹信息的相似度的方式还可以为：
第一电子设备100根据第一蓝牙外设300的轨迹信息中的GPS定位信息，计算第一蓝牙外设300的轨迹信息指示的移动距离，以及第一电子设备100的轨迹信息中的GPS定位信息，计算第一电子设备100的轨迹信息指示的移动距离。
进而，第一电子设备100根据算式
Figure PCTCN2022091339-appb-000010
计算第一电子设备100的轨迹信息和更新后的第一蓝牙外设300的轨迹信息的相似度。其中，S1为第一电子设备100第一蓝牙外设300的轨迹信息指示的移动距离，S2为第一电子设备100的轨迹信息指示的移动距离，S为第一电子设备100的轨迹信息和更新后的第一蓝牙外设300的轨迹信息的相似度。
另外，上述的目标状态是以第一电子设备100被用户携带上高铁的移动状态为例说明。在另一些实施例中，上述的目标状态还可以为第一电子设备100被用户携带上火车的移动状态；第一电子设备100被用户携带上行驶在高速公路的车辆上的移动状态，在此不作限定。
