Description

设备标识符获取方法及装置
本申请要求于2021年10月22日提交中国专利局、申请号为202111232300.9、申请名称为“设备标识符获取方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及网络技术领域，尤其涉及一种设备标识符获取方法及装置。
背景技术
通信在设备的数据采集和数据处理等数据分析场景中，设备的数据(例如基于设备的应用、服务和系统的数据)通常包括较多的敏感信息，如用户身份证号、电话、地址、信用卡号码等，一旦发生泄密，将造成不必要的损失和危害。为了避免敏感信息的泄露，通常对设备的数据进行脱敏处理，以保证数据的安全性。
设备标识符用于标识设备的数据，通过设备标识符能够实现对设备的数据的获取，并且能够识别数据中的敏感信息，因此设备标识符对于数据的安全性尤为重要。但是目前的各种设备标识符的安全性均较低，导致数据的泄露风险较大。
因此亟需一种保证数据安全性以及减小数据泄露风险的设备标识符。
发明内容
本申请提供一种设备标识符获取方法及装置，减小了目标设备标识符标识的数据的种类和数量，从而提高了设备的数据安全性和隐私性。
第一方面，本申请提供一种设备标识符获取方法，所述方法包括：确定目标有效期；获取对应所述目标有效期的目标设备标识符，所述目标设备标识符在所述目标有效期内有效，不同有效期对应的设备标识符不同，所述目标设备标识符用于采集所述目标有效期内的数据。
该方法中，目标设备标识符仅在目标有效期内有效，因此不同有效期对应的设备标识符不同，使得应用在获取到目标设备标识符后只能采集目标有效期内设备的数据，减小了目标设备标识符标识的数据的种类和数量，从而提高了设备的数据安全性和隐私性。
在一种可能的实现方式中，所述目标有效期包括以下至少一种字符：起始时间字段、截止时间字段、有效时间单位字段、有效时长字段。
在一种可能的实现方式中，所述目标有效期包括所述起始时间字段和所述截止时间字段中的任一时间字段以及所述有效时间单位字段，所述任一时间字段的时间单位和所述有效时间单位字段所指示的时间单位相同。
其中，起始时间字段用于指示目标有效期的起始时间，该起始时间可以为获取请求的接收时间。截止时间字段用于指示目标有效期的截止时间，可以将接收时间作为起始时间，根据接收时间和目标范围信息得到截止时间。有效时间单位字段所指示的有效时间单位可 以基于目标范围信息中的第一有效时间单位得到，有效时长字段用于指示目标有效期的持续时长，该持续时长可以大于或等于目标范围信息中的有效时长。
在一种可能的实现方式中，所述确定目标有效期，包括：接收设备标识符的获取请求，所述获取请求用于指示目标范围信息，所述目标范围信息包括有效时长或第一有效时间单位；基于所述获取请求的接收时间和所述目标范围信息，确定所述目标有效期，所述接收时间和所述目标范围信息组成的时间段属于所述目标有效期。
获取请求可以是任一应用所运行的设备发送的，例如是任一应用所运行的设备在数据采集事件发生时发送的。任一应用所运行的设备可以与接收获取请求的设备相同或不同，即任一应用所运行的设备与接收获取请求的设备为分布式设备组网场景中的两个设备。
获取请求指示目标范围信息的方式有多种。在一种实现方式中，获取请求可以直接指示目标范围信息。在另一种实现方式中，获取请求可以直接指示设备标识符的使用目的。设备根据获取请求确定使用目的，之后基于使用目的确定目标范围信息。设备可以根据使用目的确定数据获取过程所需的时长，根据该时长确定目标范围信息。
设备中可以预先存储有多种使用目的与多个范围信息的对应关系，在接收到获取请求后，基于该对应关系将获取请求所指示的使用目的对应的范围信息确定为目标范围信息。可选地，获取请求中可以携带有目的字符串，该目的字符串用于指示使用目的。设备中可以存储有多个目的字符串与多个范围信息的对应关系。
接收时间可以为绝对时间或相对时间。示例地，当接收时间为绝对时间时，其可以是接收到获取请求的时间。当接收时间为相对时间时，其可以是接收到获取请求的时间与参考时间的相对时间，即先确定接收到获取请求的时间与参考时间的间隔，之后以参考时间为起始，将经过间隔后的时间确定为接收时间。
在一种可能的实现方式中，所述目标范围信息包括所述第一有效时间单位，所述基于所述获取请求的接收时间和所述目标范围信息，确定所述目标有效期，包括：基于所述接收时间和所述第一有效时间单位，确定第一有效期和/或第二有效期为所述目标有效期，所述第一有效期和所述第二有效期均包括所述起始时间字段和所述截止时间字段中的任一时间字段以及所述有效时间单位字段；所述第一有效期中的所述任一时间字段和所述有效时间单位字段分别指示所述接收时间和所述第一有效时间单位；所述第二有效期中的所述任一时间字段和所述有效时间单位字段分别指示所述接收时间的近邻时间和所述第一有效时间单位，或者分别指示所述接收时间和第二有效时间单位；所述近邻时间与所述接收时间的时间间隔为至少一个所述第一有效时间单位，所述第二有效时间单位长于所述第一有效时间单位，所述第一有效期中的所述接收时间的时间单位、所述第二有效期中的所述近邻时间的时间单位与所述第一有效时间单位相同，所述第二有效期中的所述接收时间的时间单位与所述第二有效时间单位相同。
在一种可能的实现方式中，所述基于所述接收时间和所述第一有效时间单位，确定第一有效期和/或第二有效期为所述目标有效期，包括：基于所述接收时间和所述第一有效时间单位确定所述第一有效期；当所述第一有效期中的剩余有效时长大于时长阈值时，确定所述第一有效期为所述目标有效期，所述剩余有效时长为所述第一有效期的截止时间与所述接收时间的差值；当所述剩余有效时长小于或等于所述时长阈值时，基于所述接收时间和所述第一有效时间单位确定所述第二有效期，并确定所述第一有效期和所述第二有效期 为所述目标有效期。
当第一有效期的剩余有效时长小于或等于时长阈值时，会导致数据获取过程的时长过短，获取到的数据数量和种类均较少，进而出现无法达到使用目的的情况。因此当第一有效期的剩余有效时长，可以确定第二有效期，增加目标有效期的剩余有效时长，这样可以获取到足够数量和种类的数据，保证了使用目的的实现。
在一种可能的实现方式中，所述获取对应所述目标有效期的目标设备标识符，包括：根据所述目标有效期生成所述目标设备标识符。
设备可以根据目标有效期获取目标设备标识符信息，该目标设备标识符信息包括用于指示目标设备标识符的字段和用于指示目标有效期的字段。可选地，该目标设备标识符信息还可以包括时区字段，时区字段用于指示目标有效期中包括的任一时间字段所指示的时间对应的时区。
设备可以获取设备的硬件信息，之后根据硬件信息和目标有效期生成目标设备标识符，再生成目标设备标识符信息，以使目标设备标识符和目标有效期对应。可选地，设备可以利用哈希算法对硬件信息与目标有效期中的部分或全部字段进行哈希处理得到目标设备标识符。
在一种可能的实现方式中，所述获取对应所述目标有效期的目标设备标识符，包括：将多个设备标识符中对应的有效期包括所述目标有效期的设备标识符确定为所述目标设备标识符，所述多个设备标识符分别对应有效期，任意两个设备标识符对应的有效期不同。设备可以自行确定目标有效期，之后预先生成对应多个有效期的设备标识符。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本文中术语“和/或”，仅仅是一种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这三种情况。
本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一范围和第二范围等是用于区别不同的范围，而不是用于描述范围的特定顺序。
在本申请实施例中，“在一种示例中”、“示例地”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“在一种示例中”、“示例地”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“在一种示例中”、“示例地”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，除非另有说明，“至少一个”的含义是指一个或多个，“多个”的含义是指两个或两个以上。例如，多个处理单元是指两个或两个以上的处理单元；多个系统是指两个或两个以上的系统。
在用户行为分析、故障分析以及大数据统计等数据分析场景中，设备标识符用于标识设备的数据，通过设备标识符能够实现对设备的数据的获取，并且能够识别数据中的敏感信息。
本申请实施例中，设备可以为终端设备。例如可以包括：接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理以及终端装置等。接入终端可以包括：蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备、连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，第五代移动通信技术(5th Generation Mobile Communication Technology，5G)网络中的终端设备或者演进的公共陆地移动网(Public Land Mobile Network，PLMN)中的终端设备等。
目前的设备标识符通常包括：国际移动设备识别码(International Mobile Equipment Identity，IMEI)、序列号(Serial Number，SN)、移动设备识别码(Mobile Equipment Identifier，MEID)、设备唯一标识符(Unique Device Identifier，UDID)、匿名设备标识符(Open Anonymous Device Identifier，OAID)、安卓身份标识号(Android Identity document，AndroidId)、开放设备标识符(Open Device Identifier，ODID)和通用唯一识别码(Universally Unique Identifier，uuid)。
现有的设备标识符通常固定不变，且为了保证设备的数据安全性，设备对于设备标识符获取权限的管理较为严格。设备标识符固定不变会导致设备标识符所标识的数据的种类和数量均逐渐增加，从而导致设备被追踪的可能性较大且设备的数据安全性较低，设备的数据泄露风险较大。设备标识符获取权限的管理较为严格会提高设备标识符的获取难度 (例如部分应用获取设备标识符的难度)，从而影响部分数据分析过程的正常进行。
进一步地，对于可以实现跨设备的应用体验的分布式设备组网场景，需要获取该组网场景中多个设备的设备标识符，根据多个设备的设备标识符能够获取到多个设备的数据，导致获取到的数据量增大，从而导致多个设备的数据安全性均较低。
目前亟需一种保证数据安全性以及减小数据泄露风险的设备标识符。相关技术中，设备采集可识别的设备标识，并向服务端发送该设备标识。服务端将接收到的设备标识通过预设算法转化成不可逆的设备标识符，并向设备发送该设备标识符。设备将设备标识符存储至不可更新存储区域。该过程中服务端存储有原始的设备标识，因此可以从服务端获取到原始的设备标识，从而获取到设备的数据，导致设备的数据安全性较低。此外，服务端生成设备标识符的过程需要在联网环境下进行，当处于无联网环境时，服务端无法生成设备标识符，因此相关技术的适用性较差。
本申请实施例提供了一种设备标识符获取方法，该设备标识符获取方法可以应用于前述设备，例如可以应用于第一设备。当设备标识符获取方法应用于第一设备时，该方法可以由第一设备中的不同模块执行。请参考图1，图1为本申请实施例提供的一种设备的框架示意图，图1示出了第一设备和运行在第一设备上的多个应用(包括应用A、应用B和应用C)。其中，第一设备包括数据采集模块101、设备标识符生成模块102和设备标识符管理模块103。以下以图1为例对该方法进行说明。
请参考图2，图2为本申请实施例提供的一种设备标识符获取方法的流程示意图，该方法应用于前述第一设备(例如图1所示的第一设备)。该方法可以包括以下过程：
201、接收设备标识符的获取请求，该获取请求用于指示目标范围信息，目标范围信息包括有效时长或第一有效时间单位。
该获取请求可以是任一应用所运行的设备发送的，例如是任一应用所运行的设备在数据采集事件发生时发送的。任一应用所运行的设备可以与接收获取请求的设备相同或不同，例如可以为第一设备或第二设备。当任一应用所运行的设备与接收获取请求的设备不同时，该两个设备即为分布式设备组网场景中的两个设备。
获取请求指示目标范围信息的方式有多种。在一种实现方式中，获取请求可以直接指示设备标识符的使用目的，该使用目的可以是任一应用所运行的设备基于数据采集事件确定的。设备根据获取请求确定使用目的，之后基于使用目的确定目标范围信息。设备可以根据使用目的确定数据获取过程所需的时长，根据该时长确定目标范围信息。时长越长确定的目标范围信息中的有效时长越长或有效时间单位越大；时长越短确定的目标范围信息中的有效时长越短或有效时间单位越小。
其中，有效时间单位可以包括以下至少一种：年、季度、月、日、时、分、秒等。有效时长的时间单位可以参考有效时间单位，本申请实施例在此不做赘述。
设备中可以预先存储有多种使用目的与多个范围信息的对应关系，在接收到获取请求后，基于该对应关系将获取请求所指示的使用目的对应的范围信息确定为目标范围信息。可选地，获取请求中可以携带有目的字符串，该目的字符串用于指示使用目的。设备中可以存储有多个目的字符串与多个范围信息的对应关系。其中，目的字符串的类型可以包括文本字符串、符号串和二进制数字串等，例如目的字符串可以为多位数的编码，本申请实施例对此不做限定。
示例地，使用目的可以包括以下至少一种：定位单点故障、定位应用性能卡顿、丢帧以及不流畅等故障、统计应用用户行为(例如新开发的应用页面需要统计月活、周活或日活)、对部分器件进行损耗分析(例如对电池进行损耗分析)。单点故障可以包括发生了可靠性的应用程序无响应(Application Not Response，ANR)、宕机(Crash)以及Tombstone问题，Tombstone是一种文件，其用于记录单点故障的故障信息，故障信息包括应用程序的基本信息、Crash的发生地址以及Crash发生时的堆栈调用信息等。定位单点故障、定位应用性能卡顿、丢帧以及不流畅等故障、统计应用用户行为以及对部分器件进行损耗分析这四种使用目的所需的数据获取过程的时长逐渐递增。
示例地，请参考图3，图3为本申请实施例提供的一种使用目的与目标范围信息的示意图，图3以目标范围信息包括第一有效时间单位为例进行说明。如图3所示，数据采集模块在数据采集事件发生时，发送获取请求，之后根据获取请求确定使用目的。图3示出了前述四种使用目的，当使用目的为定位单点故障时确定第一有效时间单位为时，当使用目的为定位应用性能卡顿、丢帧以及不流畅等故障时确定第一有效时间单位为天，当使用目的为统计应用用户行为时确定第一有效时间单位为月，当使用目的为对部分器件进行损耗分析时确定第一有效时间单位为年。
需要说明的是，前述使用目的以及对应的目标范围信息仅为示例性说明，并不构成对使用目的和目标范围信息的限定。只要保证基于使用目的确定的目标范围信息的时长，与该使用目的对应的数据获取过程所需的时长的差值绝对值小于差值阈值即可。例如目标范围信息包括有效时长，定位单点故障对应的有效时长可以为50分、1小时以及2小时15分等。定位应用性能卡顿、丢帧以及不流畅等故障对应的有效时长可以为22小时、1天以及1天2小时等。统计应用用户行为对应的有效时长可以为29天、1个月以及2个月3天等。对部分器件进行损耗分析对应的有效时长可以为300天、1年以及2年18天等。
在另一种实现方式中，获取请求可以直接指示目标范围信息。任一应用所运行的设备可以根据数据采集事件确定使用目的，进一步根据使用目的确定目标范围信息，该确定目标范围信息的过程可以参考上述第一种实现方式，本申请实施例在此不做赘述。
该过程201可以由图1中的设备标识符管理模块103执行。图1还示出了第二设备以及运行在第二设备上的应用(包括应用D)，第一设备与第二设备均为分布式设备组网场景中的两个设备，第二设备包括分布式通信模块104，分布式通信模块104与第一设备的数据采集模块102建立通信连接。获取请求可以是应用A至应用D中的任一应用调用所运行的设备中的相应模块向设备标识符管理模块103发送的。示例地，对于应用A至应用C中的任一应用，在数据采集事件发生时可以调用数据采集模块101向设备标识符管理模块103发送获取请求。对于应用D，在数据采集事件发生时可以调用分布式通信模块104向数据采集模块101发送指示信息，数据采集模块101根据接收到的指示信息确定应用D发生了数据采集事件，之后基于该数据采集事件向设备标识符管理模块103发送获取请求。
202、基于获取请求的接收时间和目标范围信息，确定目标有效期，接收时间和目标范围信息组成的时间段属于目标有效期。
该过程可以由图1所示的设备标识符管理模块103执行。接收时间可以为绝对时间或相对时间。示例地，当接收时间为绝对时间时，其可以是接收到获取请求的时间。当接收时间为相对时间时，其可以是接收到获取请求的时间与参考时间的相对时间，即先确定接 收到获取请求的时间与参考时间的间隔，之后以参考时间为起始，将经过间隔后的时间确定为接收时间。例如，参考时间可以为1971年1月1日00:00:00。接收到获取请求的时间对应的时区可以为24个时区中的任一个，例如可以为东八区(即北京时间)。
目标有效期可以包括以下至少一种字符：起始时间字段、截止时间字段、有效时间单位字段、有效时长字段。当目标有效期包括起始时间字段和截止时间字段中的任一时间字段以及有效时间单位字段时，任一时间字段的时间单位和有效时间单位字段所指示的时间单位相同。
可选地，目标有效期可以包括起始时间字段和截止时间字段，或者包括起始时间字段和截止时间字段中的任一个，以及有效时间单位字段和有效时长字段中的任一个，只要能够基于包括的字符得到一个时间段即可，本申请实施例对此不做限定。
其中，起始时间字段用于指示目标有效期的起始时间，该起始时间可以为获取请求的接收时间。截止时间字段用于指示目标有效期的截止时间，可以将接收时间作为起始时间，根据接收时间和目标范围信息得到截止时间。有效时间单位字段所指示的有效时间单位可以基于目标范围信息中的第一有效时间单位得到，有效时长字段用于指示目标有效期的持续时长，该持续时长可以大于或等于目标范围信息中的有效时长。
当目标范围信息包括第一有效时间单位时，可以确定有效时间单位字段所指示的内容，进而确定包括起始时间字段和截止时间字段中的任一时间字段以及有效时间单位字段的目标有效期。
可选地，可以基于接收时间和第一有效时间单位，确定第一有效期和/或第二有效期为目标有效期。第一有效期和第二有效期均包括起始时间字段和截止时间字段中的任一时间字段以及有效时间单位字段。第一有效期中的任一时间字段和有效时间单位字段分别指示接收时间和第一有效时间单位。第二有效期中的任一时间字段和有效时间单位字段分别指示接收时间的近邻时间和第一有效时间单位，或者分别指示接收时间和第二有效时间单位。近邻时间与接收时间的时间间隔为至少一个第一有效时间单位，第二有效时间单位长于第一有效时间单位。第一有效期中的接收时间的时间单位、第二有效期中的近邻时间的时间单位与第一有效时间单位相同，第二有效期中的接收时间的时间单位与第二有效时间单位相同。本申请实施例中，第二有效期的数量可以为一个或多个。
示例地，假设第一有效时间单位为日，接收时间为2021年12月18日15时，则第一有效期中，有效时间单位字段指示日，任一时间字段指示2021年12月18日，即第一有效期为2021年12月18日。在一种示例下，第二有效期中的任一时间字段和有效时间单位字段分别指示接收时间的近邻时间和第一有效时间单位。则第二有效期中，有效时间单位字段指示日，任一时间字段指示2021年12月16日、2021年12月17日、2021年12月19日或2021年12月20日等，即第二有效期为2021年12月16日、2021年12月17日、2021年12月19日或2021年12月20日。在另一种示例下，第二有效期中的任一时间字段和有效时间单位字段分别指示接收时间和第二有效时间单位。第二有效时间单位长于第一有效时间单位，第二有效时间单位可以为周、月、季度或年等，相应地，第二有效期中，任一时间字段指示2021年51周、2021年12月、2021年4季度或2021年等，即第二有效期为2021年51周、2021年12月、2021年4季度或2021年等。
可选地，可以基于接收时间和第一有效时间单位确定第一有效期。之后当第一有效期 中的剩余有效时长大于时长阈值时，确定所第一有效期为目标有效期。当剩余有效时长小于或等于时长阈值时，基于接收时间和第一有效时间单位确定第二有效期，并确定第一有效期和第二有效期为目标有效期。剩余有效时长为第一有效期的截止时间与接收时间的差值。
当第一有效期的剩余有效时长小于或等于时长阈值时，会导致数据获取过程的时长过短，获取到的数据数量和种类均较少，进而出现无法达到使用目的的情况。因此当第一有效期的剩余有效时长，可以确定第二有效期，增加目标有效期的剩余有效时长，这样可以获取到足够数量和种类的数据，保证了使用目的的实现。时长阈值的时间单位可以短于或等于第一有效期中的有效时间单位字段所指示的时间单位。
示例地，请参考图4，图4为本申请实施例提供的一种目标有效期的确定过程示意图，图4示出了数据采集模块101和设备标识符管理模块103，且图4以使用目的为定位单点故障为例进行说明。定位单点故障对应的第一有效时间单位为日，假设时长阈值为0.5时，数据采集模块101在数据采集行为发生时向设备标识符管理模块103发送获取请求，获取请求的接收时间为2021年4月5日23时58分。此时确定的第一有效期为2021年4月5日，第一有效期的剩余有效时长为2分，剩余有效时长小于0.5时，因此可以确定第二有效期。图4以第二有效期的任一时间字段和有效时间单位字段分别指示接收时间的近邻时间和第一有效时间单位为例，且示出了三个第二有效期，该三个第二有效期分别为2021年4月6日、2021年4月7日和2021年4月8日。
需要说明的是，对于第一有效期或第二有效期，由于任一时间字段的时间单位和有效时间单位字段相同，因此起始字符和截止时间字段所指示的内容是一样的，即均指示接收时间。例如对于第一有效期，假设接收时间为2021年12月18日15时，第一有效时间单位为日，则起始时间字段串和截止时间字段串所指示的内容均为2021年12月15日。
对于目标有效期的截止时间字段，当目标范围信息包括有效时长时，可以将从接收时间开始经过有效时长之后的时间确定为截止时间字段所指示的截止时间。当目标范围信息包括第一有效时间单位时，可以将第一有效时间单位作为接收时间的时间单位，以确定截止时间。示例地，假设有效时长为20天，接收时间为2021年4月1日，则可以将2021年4月20日确定为截止时间。假设第一有效单位为月，则将接收时间所在的月的最后一天确定为截止时间，例如假设接收时间为2021年4月7日，则将2021年4月30日确定为截止时间。假设第一有效单位为年，则将接收时间所在的年的最后一天确定为截止时间，例如假设接收时间为2021年4月7日，则将2021年12月31日确定为截止时间。
对于目标有效期的有效时长字段，当目标范围信息包括有效时长时，可以将大于或等于目标范围信息中的有效时长的时长确定为有效时长字段所指示的内容。当目标范围信息包括第一有效时间单位时，可以将第一有效时间单位作为接收时间的时间单位，以确定有效时长字段所指示的内容。示例地，假设有效时长为20天，则可以将20天、21天或22天等确定为有效时长字段所指示的内容。假设第一有效单位为月，接收时间为2021年4月8日，则可以将2021年4月中从2021年4月8日开始至2021年4月的最后一天结束的时长确定为有效时长字段所指示的内容，即将23天确定为有效时长字段所指示的内容。
目标有效期中各个字段的格式有多种，示例地，以目标有效期包括起始时间字段或截止时间字段中的任一时间字段以及有效时间单位字段为例，假设任一时间字段所指示的时 间为2021年4月1日15时，有效时间单位字段为年、月、周、日或时，相应地，任一时间字段指示的内容可以表示为2021、202104、202114、20210401或2021040115。
203、获取对应目标有效期的目标设备标识符，目标设备标识符在目标有效期内有效，不同有效期对应的设备标识符不同，目标设备标识符用于采集目标有效期内的数据。
设备可以根据目标有效期获取目标设备标识符信息，该目标设备标识符信息包括用于指示目标设备标识符(也可称为目标UDID)的字段和用于指示目标有效期的字段。可选地，该目标设备标识符信息还可以包括时区字段，时区字段用于指示目标有效期中包括的任一时间字段所指示的时间对应的时区。
获取目标设备标识符的方式有两种，第一种获取方式是直接根据目标有效期生成目标设备标识符。第二种获取方式是从已有的设备标识符中获取目标设备标识符，示例地，可以将多个设备标识符中对应的有效期包括目标有效期的设备标识符确定为目标设备标识符，多个设备标识符分别对应有效期，任意两个设备标识符对应的有效期不同。
设备可以根据目标有效期判断是否存在对应的有效期包括目标有效期的设备标识符，该过程可以由设备标识符管理模块103执行。当存在包括目标有效期的设备标识符时，可以将对应的有效期包括目标有效期的设备标识符获取为目标设备标识符，该过程可以由设备标识符管理模块103执行。也可以重新生成目标设备标识符，设备标识符管理模块103可以调用设备标识符生成模块102重新生成目标设备标识符。当不存在包括目标有效期的设备标识符时，可以直接生成目标设备标识符。设备标识符管理模块103可以调用设备标识符生成模块102直接生成目标设备标识符。
对于设备生成目标设备标识符的过程，设备可以获取设备的硬件信息，之后根据硬件信息和目标有效期生成目标设备标识符，再生成目标设备标识符信息，以使目标设备标识符和目标有效期对应。可选地，设备可以利用哈希算法对硬件信息与目标有效期中的部分或全部字段进行哈希处理得到目标设备标识符。哈希算法可以包括哈希安全散列算法(Secure Hash Algorithm，sha)，例如哈希sha256。硬件信息包括以下至少一种：SN、嵌入式多媒体卡ID(Embedded Multi Media Card ID，emmcid)、无线保真媒体存取控制位址(Wireless Fidelity Media Access Control Address，WifiMac)、蓝牙Mac(BluetoothMac)。
示例地，请参考图5，图5为本申请实施例提供的一种目标设备标识符信息的生成过程示意图。图5以目标有效期包括起始时间字段以及有效时间单位字段，且起始时间字段指示20210401为例进行说明。设备将SN、emmcid、WifiMac、BluetoothMac以及20210401经过哈希sha256得到目标设备标识符。之后将目标设备标识符、时区字段、起始时间字段(20210401)和有效时间单位字段进行拼接，得到目标设备标识符信息。
对于设备从已有的设备标识符中获取目标设备标识符的过程，设备可以预先生成对应多个有效期的设备标识符，该过程可以参考前述描述，本申请实施例在此不做赘述。设备在预先生成对应多个有效期的设备标识符时，设备可以自行确定目标有效期。假设目标有效期包括有效时间单位字段，设备可以确定多个起始时间和每个起始时间对应的多个有效时间单位，之后确定多个目标有效期，每个目标有效期包括多个起始时间中的一个起始时间和该一个起始时间对应的一个有效时间单位。
需要说明的是，当目标有效期包括以下至少一种字段：起始时间字段、截止时间字段、有效时长字段时，若已有的设备标识符对应的有效期中仅包括目标有效期中的一段时间， 时，设备可以重新生成对应目标有效期的目标设备标识符，也可以生成对应目标有效期中除一段时间之外的时间对应的目标设备标识符，本申请实施例对此不做限定。
设备在获取目标设备标识符后，可以向发送获取请求的应用发送目标设备标识符信息。发送获取请求的应用运行的设备可以为第一设备或第二设备，即本申请实施例中第二设备运行的应用也可以请求第一设备的目标设备标识符。
当目标有效期包括有效时间单位字段时，目标设备标识符可以包括时有效设备标识符、日有效设备标识符、月有效设备标识符以及年有效设备标识符等。如前述过程202所述，对应不同的使用目的，发送的目标设备标识符不同。如前述图3所示，图3还示出了不同使用目的所对应的目标设备标识符。其中，定位单点故障对应时有效目标设备标识符，定位应用性能卡顿、丢帧以及不流畅等故障对应日有效目标设备标识符，统计应用用户行为对应月有效目标设备标识符，对部分器件进行损耗分析对应年有效目标设备标识符。
此外，当目标有效期包括有效时间单位字段且目标有效期的数量为多个时，例如前述第一有效期和第二有效期，对应的目标设备标识符的数量也为多个。如前述图4所示，图4还示出了第一有效期和三个第二有效期分别对应的目标设备标识符UDID0至UDID3。UDID0至UDID3分别为2021年4月5日有效设备标识符、2021年4月6日有效设备标识符、2021年4月7日有效设备标识符和2021年4月8日有效设备标识符。因此本申请实施例中，若当前第一有效期对应的目标设备标识符的剩余有效时长过短时，可以获取第二有效期对应的设备标识符，以保证使用目的能够实现。
当目标有效期包括有效时间单位字段时，设备标识符管理模块103可以按照各种时间单位对已生成的设备标识符进行分类管理，使得能够快速判断是否存在对应的有效期包括目标有效期的设备标识符，提高了目标设备标识符的获取效率。
本申请实施例中，第一设备还可以将获取的目标设备标识符信息上报至云端，云端对目标设备标识符信息进行解析，得到目标设备标识符信息中各个字段所指示的内容，并存储解析得到的内容。云端可以根据存储的目标设备标识符信息中各个字段所指示的内容获取设备的数据，并对设备的数据进行分析。
示例地，请参考图6，图6为本申请实施例提供的一种第一设备和云端之间的交互示意图。图6示出了第一设备和云端，云端包括服务器、存储模块和数据分析模块。第一设备向云端发送目标设备标识符信息，服务器对目标设备标识符信息进行解析得到目标设备标识符信息中的各个字段所指示的内容，并将各个字段所指示的内容存储至存储模块。之后数据分析模块可以利用存储模块中存储的目标设备标识符信息中的各个字段所指示的内容，进行数据分析。示例地，数据分析可以包括：电池老化分析、可靠性分析以及用户行为分析等。
以下以一种数据分析场景为例对云端的数据分析过程进行说明，该数据分析场景为云端分析2021年4月第一设备(例如手机)投屏至第二设备(例如电视)的时延。第一设备可以获取并向云端发送第一设备和第二设备的2021年4月对应的目标设备标识符，第二设备可以获取并向云端发送第二设备的2021年4月对应的目标设备标识符。云端基于第一设备发送的第一设备和第二设备的2021年4月对应的目标设备标识符，将第一设备和第二设备的2021年4月对应的目标设备标识符关联，以确定第一设备的投屏对象。在2021年4月进行的投屏过程中，第一设备向第二设备发送投屏请求并同时向云端发送投 屏事件。第二设备接收投屏请求并同时向云端发送接收投屏事件。之后第一设备向第二设备发送投屏数据流，第二设备读取投屏数据流并同时向云端发送读取数据流事件。
需要说明的是，第二设备也会向云端发送其他时间对应的目标设备标识符以及在其他时间发生的事件。例如第二设备可以获取并向云端发送第二设备的2021年5月对应的目标设备标识符。并在2021年5月接收到打开某一应用(例如视频应用)的指令时，打开某一应用并同时向云端发送打开某一应用事件。
这样云端在根据第一设备和第二设备的2021年4月对应的目标设备标识符，对2021年4月第一设备投屏至第二设备的时延进行分析时，2021年4月对应的目标设备标识符仅会标识2021年4月投屏过程对应的数据，其他时间设备的数据不会被标识(例如2021年5月打开某一应用事件对应的数据)，云端也不会分析第一设备和第二设备在2021年4月之外的时间的数据。从而在减小了数据分析过程中数据的数量和种类的同时，提高了设备的数据安全性和隐私性。
示例地，请参考图7，图7为本申请实施例提供的一种云端的数据分析过程所用到的参数示意图，如图7所示，参数包括第一设备的相关参数和第二设备的相关参数。相关参数包括：设备类型、目标设备标识符、目标有效期起始时间、目标有效期截止时间、时区、目标有效期的有效时间单位，以及各种事件的事件名称、事件发生时间和事件参数。图7示出了两个设备的2021年4月对应的目标设备标识符以及在2021年4月发生的投屏过程的事件名称、事件发生时间和事件参数。且图7还示出了第二设备的2021年5月对应的目标设备标识符以及在2021年5月发生的打开某一应用事件名称、事件发生时间和事件参数。
综上所述，本申请实施例提供的设备标识符获取方法，可以确定目标有效期，之后获取对应目标有效期的目标设备标识符，目标设备标识符在目标有效期内有效，不同有效期对应的设备标识符不同，目标设备标识符用于采集目标有效期内的数据。目标设备标识符仅在目标有效期内有效，因此不同有效期对应的设备标识符不同，使得应用在获取到目标设备标识符后只能采集目标有效期内设备的数据，减小了目标设备标识符标识的数据的种类和数量，从而提高了设备的数据安全性和隐私性。
此外，可以基于接收到的应用发送的获取请求确定有效期。获取请求可以直接指示设备标识符的使用目的或者指示目标范围信息，目标范围信息包括有效时长或第一有效时间单位。这样可以使得设备上运行的应用在采集设备的数据之前均需要确定设备的数据的使用目的或目标范围信息，以获取相应目标有效期对应的目标设备标识符。从而避免恶意应用采集并泄露设备的数据的情况出现。
本申请实施例提供的方法的先后顺序可以进行适当调整，过程也可以根据情况进行相应增减。例如前述过程101和102也可以不执行，而是直接确定目标有效期。任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本申请的保护范围之内，本申请实施例对此不做限定。
