Description

一种确定密切接触者的方法、终端设备及服务器 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种确定密切接触者的方法、终端设备及服务器。
背景技术
新冠肺炎(corona virus disease 2019，COVID-19)防控工作一直持续，在密切接触者判断上，传统方法只能依赖于采用运营商信号路径或者用户手填路径来生成二维码的方式来判断是否是密切接触者。
运营商信号路径判断是否是密切接触者(是否是新冠肺炎感染着的密切接触者)的具体方式为：基于手机信号塔识别用户手机信号14日内途径的城市是否为重疫区，以此来判断手机用户是否为新冠肺炎感染者的密切接触者。用户主动填路径判断是否是密切接触者的具体方式为：手机用户在手机上主动填写每日途径的路线(含交通工具及班次)及地址，或者用户用手机扫描途径路径上的二维码，如果同路线及地址有用户被诊断为新冠肺炎感染者，则途径此路线及地址的所有用户均为密切接触者，需要在家隔离并做检测。
但是采用运营商信号路径的方法，只能识别出用户在某个城市，而不能精确到街道，对于同个城市不同区无法处理，而采用用户手填路径的方法，一些用户可能漏填、填写错或故意不填，因此现有的判断密切接触者的方法会存在判断不够精准的问题。
发明内容
本发明实施例提供一种确定密切接触者的方法、终端设备及服务器，用以解决现有的判断密切接触者的方法会存在判断不够精准的问题。
为了解决上述技术问题，本发明实施例是这样实现的：
第一方面，提供一种确定密切接触者的方法，包括：
终端设备向服务器发送请求消息，所述请求消息用于请求目标用户的身份标识；
所述终端设备接收所述服务器发送的所述目标用户的身份标识；
若所述终端设备本地存储的身份标识中存在与所述目标用户的身份标识匹配的身份标识，则确定所述终端设备的用户为所述目标用户的密切接触者；
所述本地存储的身份标识为与所述终端设备建立过短距离无线通信连接的设备的用户的身份标识。
第二方面，提供一种确定密切接触者的方法，包括：
服务器接收终端设备发送的请求消息，所述请求消息用于请求目标用户的身份标识；
所述服务器将存储的目标用户的身份标识发送给终端设备。
第三方面，提供一种终端设备，该终端设备包括：发送模块，用于向服务器发送请求消息，所述请求消息用于请求目标用户的身份标识；
接收模块，用于接收所述服务器发送的所述目标用户的身份标识；
确定模块，用于若终端设备本地存储的身份标识中存在与所述目标用户的身份标识匹配的身份标识，则确定所述终端设备的用户为所述目标用户的密切接触者；
所述本地存储的身份标识为与所述终端设备建立过短距离无线通信连接的设备的用户的身份标识。
第四方面，提供一种服务器，该服务器包括：接收模块，用于接收终端设备发送的请求消息，所述请求消息用于请求目标用户的身份标识；
发送模块，用于将存储的目标用户的身份标识发送给终端设备。
第五方面，提供一种终端设备，该终端设备包括：处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第一方面所示的确定密切接触者的方法。
第六方面，提供一种服务器，该终端设备包括：处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第二方面所示的确定密切接触者的方法。
第七方面，提供一种计算机可读存储介质，包括：所述计算机可读存储介质上存储计算机程序，计算机程序被处理器执行时，实现第一方面所示的确定密切接触者的方法，或者，实现第二方面所示的确定密切接触者的方法。
在本发明实施例中，终端设备可以向服务器发送用于请求目标用户的身份标识的请求消息，并在接收到服务器发送的目标用户的身份标识之后，可以查看终端设备本地存储的与所述终端设备建立过短距 离无线通信连接的设备的用户的身份标识中，是否有与目标用户的身份标识匹配的身份标识，如果有则说明与终端设备的用户近距离接触过的用户中有目标用户，从而确认终端设备的用户为目标用户的密切接触者。这样可以基于短距离的无线通信技术获取让终端设备存储与终端设备的用户近距离接触过的用户的身份标识，并结合服务器中存储的目标用户的身份标识，自动对终端设备的用户是否为密切接触者进行判断，这样可以提高确定密切接触者的精确度。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“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它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。
本发明实施例中的终端设备可以为具有操作系统的终端设备。该操作系统可以为安卓(Android)操作系统、ios操作系统或者鸿蒙操作系统，还可以为其他可能的操作系统，本发明实施例不作具体限定。
下面以安卓操作系统为例，介绍一下本发明实施例提供的确定密切接触者的方法所应用的软件环境。
如图1所示，为本发明实施例提供的一种可能的安卓操作系统的架构示意图。在图1中，安卓操作系统的架构包括4层，分别为：应用程序层、应用程序框架层、系统运行库层和内核层(具体可以为Linux内核层)。
其中，应用程序层包括安卓操作系统中的各个应用程序(包括系统应用程序和第三方应用程序)。
应用程序框架层是应用程序的框架，开发人员可以在遵守应用程序的框架的开发原则的情况下，基于应用程序框架层开发一些应用程序。
系统运行库层包括库(也称为系统库)和安卓操作系统运行环境。库主要为安卓操作系统提供其所需的各类资源。安卓操作系统运行环境用于为安卓操作系统提供软件环境。
内核层是安卓操作系统的操作系统层，属于安卓操作系统软件层次的最底层。内核层基于Linux内核为安卓操作系统提供核心系统服务和与硬件相关的驱动程序。
以安卓操作系统为例，本发明实施例中，开发人员可以基于上述如图1所示的安卓操作系统的系统架构，开发实现本发明实施例提供的确定密切接触者的方法的软件程序，从而使得该确定密切接触者的方法可以基于如图1所示的安卓操作系统运行。即处理器或者终端设备可以通过在安卓操作系统中运行该软件程序实现本发明实施例提供的确定密切接触者的方法。
本发明实施例中的终端设备可以为移动终端设备，也可以为非移动终端设备。移动终端设备可以为手机、平板电脑、笔记本电脑、掌上电脑、车载终端设备、可穿戴设备、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本或者个人数字助理(personal digital assistant，PDA)等；非移动终 端设备可以为个人计算机(personal computer，PC)、电视机(television，TV)、柜员机或者自助机等；本发明实施例不作具体限定。
本发明实施例中的服务器可以为传统服务器，也可以为云端服务器。
本发明实施例提供的确定密切接触者，可以应用于确定特定人员(本发明实施例中的目标用户)的密切接触者。
可选的，该特征人员可以是指传染疾病的患者，例如，新冠肺炎的感染者。
本发明实施例提供的确定密切接触者的方法可以应用于如图2所示的通信系统中，假设该通信系统是应用于确定新冠肺炎的感染者的密切接触者。该系统中包括有：云端服务器、手机A、手机B和手机C。其中，手机B与手机A和手机C曾处于较短距离内，因此手机B的用户与手机A的用户可能曾经亲密接触，手机B的用户与手机C的用户也有可能曾经亲密接触，这样手机C中可以保存手机B的用户的身份代码B1，而手机A中可以保存手机B的身份代码B1，手机B中可以保存手机A的身份代码A1和手机C的身份代码C1。在手机C的用户被确认为感染者的情况下，可以上传自己的身份代码给云端服务器，云端服务器会将手机C的用户的身份代码C1保存为感染者的身份代码。进一步的，手机A可以从云端服务器获取感染者的身份代码C1之后可以查询本地的身份代码，其中，不包括C1，因此手机A的用户不是感染者的密切接触者；手机B也可以从云端服务器获取感染者的身份代码C1之后可以查询本地的身份代码，其中，包括C1，因此手机B的用户是感染者的密切接触者。
其中，上述的较短距离内可以是指短距离通信连接的距离范围内，该距离范围可以根据该短距离通信连接能够建立的最大距离确定。假设，通过蓝牙连接的话，距离范围可以为200米内。图2中，100米和10米均处于该距离范围内。
本发明实施例提供的确定密切接触者的方法的可以通过终端设备与服务器的信息交互实现，下面将结合附图对本发明实施例提供的确定密切接触者的方法进行示例性说明。
如图3所示，本发明实施例提供一种确定密切接触者的方法，该方法包括：
101、终端设备获取与终端设备建立短距离无线通信连接的设备的用户的身份代码。
其中，该设备的用户的身份代码为根据该设备的设备标识生成的。
可选的，终端设备获取与终端设备建立短距离无线通信连接的设备的用户的身份代码可以为以下两种情况：
第一种情况：终端设备获取与终端设别建立短距离无线通信连接的设备的设备标识，并根据该设备标识生成该设备的身份代码。
第二种情况：该设备根据其设备标识生成该设备的用户的身份代码，终端设备直接获取该设备的用户的身份代码。
102、终端设备将该设备的用户的身份代码本地存储。
本发明实施例中，终端设备可以将该设备的用户的身份代码本地存储，以记录终端设备近距离接触过的人员。
可选的，终端设备还可以获取该终端设备的设备标识，并根据终端设备的设备标识，生成该终端设备的用户的身份代码，将该终端设备的用户的身份代码本地存储。
103、终端设备向服务器发送请求消息。
相应的，服务器接收终端设备发送的请求消息。
其中，请求消息用于向服务器请求目标用户的身份标识。
可选的，本发明实施例中，可以在终端设备确定终端设备的用户不是目标用户的情况下，终端设备向服务器发送请求消息。
可选的，终端设备可以通过终端设备的用户输入的信息来确定终端设备的用户是不是目标用户，或者终端可以通过第三方平台(如，新闻平台、医疗系统、国家组织或机构等)公布的目标用户的信息确定终端设备的用户是不是目标用户。
104、服务器将存储的目标用户的身份标识发送给终端设备。
本发明实施例中，服务器可以接收各个终端设备发送的目标用户的身份标识，并进行保存。
105、若终端设备本地存储的身份标识中存在与目标用户的身份标识匹配的身份标识，则确定终端设备的用户为目标用户的密切接触者。
其中，本地存储的身份标识为与终端设备建立过短距离无线通信连接的设备的用户的身份标识。
需要说明的是，本发明实施例中终端设备本地存储的身份标识中存在与目标用户的身份标识匹配的身份标识可以是指终端设备本地存储的身份标识中存在与目标用户的身份标识相同的身份标识，或者可 以是指终端设备本地存储的身份标识中存在与目标用户的身份标识存在某种关联关系的身份标识，其中该关联关系应该可以指示两个身份标识对应于同一用户。
其中，上述短距离无线通信连接可以是指蓝牙连接，或者，近距离无线通信(near field communication，NFC)技术建立的连接等。
在本发明实施例中，终端设备可以向服务器发送用于请求目标用户的身份标识的请求消息，并在接收到服务器发送的目标用户的身份标识之后，可以查看终端设备本地存储的与终端设备建立过短距离无线通信连接的设备的用户的身份标识中，是否有与目标用户的身份标识匹配的身份标识，如果有则说明与终端设备的用户近距离接触过的用户中有目标用户，从而确认终端设备的用户为目标用户的密切接触者。这样可以基于短距离的无线通信技术获取让终端设备存储与终端设备的用户近距离接触过的用户的身份标识，并结合服务器中存储的目标用户的身份标识，自动对终端设备的用户是否为密切接触者进行判断，这样可以提高确定密切接触者的精确度。
进一步的，由于本发明实施例提供的方法无需获取终端设备的用户的位置数据和路径信息，并且判断密切接触者的逻辑都在终端设备本地实现，而服务器中只需维护目标用户的身份标识信息，因此实现了最大化的保护用户隐私。
此外，还避免了手动填写路径的方式中，一些用户因为漏填、填错或者隐瞒不填而导致的信息不准确，进一步的提高了确定密切接触者的精确度。
可选的，结合图3，如图4所示，上述105可以替换为下述106。
106、若终端设备本地存储的身份标识中不存在与目标用户的身份标识匹配的身份标识，则确定终端设备的用户非目标用户的密切接触者。
可选的，在终端设备确定终端设备的用户为目标用户的情况下，终端设备可以向服务器发送终端设备的用户的身份代码，终端设备的用户的身份代码为根据终端设备的设备标识生成的。
示例性的，结合图3，如图5所示，上述105之后还可以包括以下步骤：
107、终端设备确定终端设备的用户为目标用户。
示例性的，在确定终端设备的用户为新冠肺炎的密切接触者之后，可以通过核酸检测等检测手段判断其是否为新冠肺炎的感染者(即目标用户)，并将结果录入至终端设备中。
108、终端设备向服务器发送终端设备的用户的身份代码。
相应的，服务器接收终端设备发送的终端设备的用户的身份代码，终端设备的用户的身份代码为根据终端设备的设备标识生成的。
示例性的，在确定终端设备的与用户为新冠肺炎的感染者之后，可以将终端设备的用户的身份代码发送给服务器，以使得服务器可以保存终端设备的用户的身份代码，以更新服务器中的感染者的身份代码信息(即，目标用户的身份代码信息)。
109、服务器将终端设备的用户的身份代码作为目标用户的身份代码进行存储。
本发明实施例中，可以在终端设备的用户确定为目标用户时，及时向服务器上报其身份代码，以使得服务器可以及时更新服务器中存储的目标用户的身份代码信息，从而可以进一步提高确定密切接触者的精确度。
在实际应用中，本发明实施例提供的确定密切接触者的方案可以包括两部分，第一部分为终端设备本地生成身份代码库(即存储终端设备的用户的身份代码，以及存储与终端设备建立短距离无线通信连接的其他设备的用户的身份代码)；第二部分为终端设备查询是否密切接触者。以下分别对这两部分内容进行介绍。
第一部分：终端设备生成身份代码
在这部分内容中，如图6所示，终端设备通过以下步骤实现：
201、开启快应用。
可选的，可以接收用户开启快应用的操作，以开启快应用。
上述快应用可以为基于本发明实施例提供的确定密切接触者的方法开发的应用程序。
202、判断用户是否已经授权生成身份代码库。
若用户已授权，则执行203至206；若用户未授权，则执行207。
203、判断是否开启蓝牙功能。
若开启了，则执行204和205；若未开启，则执行206。
204、获取与终端设备建立短距离无线通信连接的其他设备的用户的身份代码。
205、将其他设备的用户的身份代码存储在身份代码库。
206、输出开启蓝牙功能的引导信息，引导用户开启蓝牙功能。
本发明实施例中，206之后可以返回执行203。
207、显示询问用户是否允许授权的弹框。
若接收到用户允许授权的输入，则执行208至210；若用户接收到用户不允许授权的输入，则执行211。
208、获取终端设备的设备标识。
209、生成终端设备的用户的身份代码。
210、将终端设备的用户的身份代码保存至身份代码库。
211、输出允许授权的引导信息，引导用户授权生成身份代码库。
本发明实施例中，在执行211之后可以返回执行207。
可选的，可以先输出引导查询密切接触者情况的信息，并提示查询密切接触者情况需要先允许授权生成身份代码库。
第二部分：终端设备查询是否密切接触者
示例性的，以目标用户为新冠肺炎感染者为例，在这部分内容中，如图7所示，终端设备和服务器通过以下步骤实现：
301、用户触发终端设备查询密切接触者情况。
302、终端设备判断是否开启蓝牙功能。
若开启了蓝牙功能，则执行303至314；若未开启蓝牙功能，则执行315。
303、终端设备显示用户信息输入界面。
304、终端设备响应于用户在用户信息输入界面的操作，录入用户的健康状态信息。
305、终端设备判断终端设备的用户是否为感染者。
若终端设备的用户不是感染者，则执行306至311；若终端设备的用户是感染者，则执行312至314。
306、向服务器请求感染者身份代码。
307、服务器下发感染者身份代码库中的感染者身份代码给终端设备。
308、终端设备将感染者身份代码与本地身份代码库中的身份代码进行匹配。
309、判断本地身份代码库中是否存在匹配的身份代码。
若存在，则执行310；若不存在，则执行311。
310、确定终端设备的用户为感染者的密切接触者。
311、确定终端设备的用户不是感染者的密切接触者。
312、终端设备向服务器上报终端设备的用户的身份代码。
313、服务器接收终端设备上报的身份代码。
314、服务器将终端设备的用户的身份代码保存在感染者身份代码库。
315、终端设备输出开启蓝牙功能的引导信息，引导用户开启蓝牙功能。
本发明实施例中，315之后可以返回执行302。
可选的，本发明实施例中为确保身份代码不被恶意获取及跟踪，身份代码还可做混淆优化，即手机设备之间互相广播的身份代码不会唯一不变、而是会随着蓝牙MAC地址随机变化而变化。
示例性的，如图8所示，手机2广播的是临时身份代码b，由手机2身份代码B进行动态生成，单个手机可广播任意数量的代码b，避免了单个用户被恶意跟踪等问题。图8中，手机1的用户与手机2的用户近距离交流了一段时间后，手机1广播了三个临时身份代码b1、b2和b3，手机2广播了三个临时身份代码a1、a2和a3，手机2知道接收了3个临时身份代码及时间，但不知道这三个临时身份代码均指示一个手机用户。
进一步的，数天后手机1的用户被确诊为新冠肺炎的感染者，可以通过卫计委或者手机1的用户自己上报身份代码B给云端服务器，在手机2的用户触发手机2从云端服务器获取新冠肺炎的感染者的身份代码B，并与本地存储的b1、b2和b3进行匹配，发现B与b1、b2和b3匹配，但是手机2的用户并不能获知b1、b2和b3指示手机1的用户。
上述实现方式可以保护手机用户的隐私，避免单个用户被恶意追踪等问题的发生。
