具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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，所描述的实施例仅仅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做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。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例能够以除了在这里图示或描述的那些以外的顺序实施。
应当理解，在本发明的各种实施例中，各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
应当理解，在本发明中，“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
应当理解，在本发明中，“多个”是指两个或两个以上。“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。字符“/”一般表示前后关联对象是一种“或”的关系。“包含A、B和C”、“包含A、B、C”是指A、B、C三者都包含，“包含A、B或C”是指包含A、B、C三者之一，“包含A、B和/或C”是指包含A、B、C三者中任1个或任2个或3个。
应当理解，在本发明中，“与A对应的B”、“与A相对应的B”、“A与B相对应”或者“B与A相对应”，表示B与A相关联，根据A可以确定B。根据A确定B并不意味着仅仅根据A确定B，还可以根据A和/或其他信息确定B。A与B的匹配，是A与B的相似度大于或等于预设的阈值。
取决于语境，如在此所使用的“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。
应当理解，在本发明中，签单，是指收货端签名后的运单，因此，运单包括收货端签名前的运单，和收货端签名后的签单。运单信息包括但不限于发货端信息、运单标识、收货端信息等。签单信息则包括运单信息以及收货端写入的收货签名信息。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
现有的签单返还操作中，物流公司需要把运单打印出来，在客户签收后，将纸质签单邮寄回寄件方，或者将签单纸件签单拍照形成电子照线上传递给寄件方。通常，打印出纸质单据后的状态有：待签、已返回仓库、签单待返、寄送商家、已完成、已取消等状态。在***中纸质单据还需要关联到快递单号和快递公司名称信息。而结合纸质单据，线上电子单据的状态有：已取消、待拍照、已拍照待确认、已完成已拍照等状态，电子单据需要先将图片上传到指定服务器***后，再将图片地址和运单号手工同步给订单***等。由于运单需要在多个不同的***中流转，例如订单***、配送***系、中间其它传输***等，***之间通过接口或消息的方式完成数据的交互。
现有的签单返还方式，是针对纸质单据的返还，纸质单据容易丢失，运营成本高并且容易被冒签；而且针对纸质单据进行拍照后上传到指定服务器，并将图片地址信息与运单进行关联后记录到信息***，因为手写签名的图片无法进行光学字符识别(Optical Character Recognition，简称：OCR)，拍照不清晰等问题，仍然需要人工对每条单据进行审核，操作复杂的同时错误率也高。不仅如此，现有的签单返还中，运单或签单的数据流会在多个***流转，***之间涉及到数据同步的问题，尤其是在不同企业之间共享数据时会涉及到信任的问题。可见，现有的签单返还方法存在效率不高以及可靠性不 高的问题。
参见图1，是本发明实施例提供的一种基于区块链的签单返还应用场景示意图。如图1所示，业务***1将订单信息进行录入，并在接收到发货端6发起的签单返还服务指令时启动签单返还服务。业务***1将生成的运单信息通过状态同步存储至区块链5，配送***2在配送过程中一旦发生运输状态的变更，将变更的运输状态同步存储至区块链。派件端3例如是派件员的手持终端，在派件员进行派件时，通过派件端3获取代签收的文件电子版，生成运单信息二维码，并向收货方用户显示。收货方用户以收货端4扫描二维码签收，并将签收后的签单信息上传至区块链存储。发货用户通过发货端6查询已返还的签单，并根据区块链中存储的签单信息进行查验，在查验正确后下载得到返还的目标签单信息。在图1所示的场景中，业务***1、配送***2、派件端3以及收货端4都在自己的环节中在运单状态发生变化时，将状态同步至区块链5，利用区块链的不可篡改的特性，实现运单信息的可靠存储和更新。最后，由发货端6主动发起签单返还流程，发货端6查询到返还的签单时，从区块链5下载相应的数据对返还的签单进行查验，查验正确则接收返还的签单，由此，基于区块链的不可篡改的存储特性，实现了可靠的签单查验和高效的签单返还。
参见图2，是本发明实施例提供的一种基于区块链的签单返还方法流程示意图，图2所示方法的执行主体可以是软件和/或硬件装置，例如是***服务器或内置于***服务器中的软件模块。***服务器又可以是提供各种服务的服务器，例如对用户利用终端设备所浏览的物流运单网页提供支持的后台管理服务器(仅为示例)。后台管理服务器可以对接收到的物流信息查询请求、签单返还请求等数据进行查找、分析等处理，并将处理结果(例如目标签单信息)反馈给终端设备。图2所示方法包括步骤S101至步骤S104，具体如下：
S101，获取发货端发出的签单返还请求。
发货端例如可以是在生成订单的同时或之后发出签单返还请求，以使***服务器在获取到目标签单信息时，根据签单返还请求向发货端进行签单返还。
S102，根据所述签单返还请求，获取预存储的目标签单信息。
可以理解为，签单返还请求中包含了发货用户想要返还的签单标识，例 如包括运单标识。运单标识例如是运单编号。***服务器在收到签单返还请求时，从签单返还请求中解析得到运单标识，并根据运单标识查找该运单标识对应的运单是否已签收，如果查找到已签收的签单信息，则将该已签收的签单信息作为目标签单信息。如果没有查找到目标签单信息，可以向收货端返回还未签收的消息或者是将当前阶段的运单信息返回给发货端，直到查找到目标签单信息。
S103，从区块链中获取所述目标签单信息对应的目标哈希值。
区块链中存储有所有运单信息对应的哈希值，在查找得到目标签单信息时，其哈希值也应预先存储在了区块链中。例如，每个签单信息都对应一个区块链存储标识，区块链存储标识用于指示签单信息对应哈希值在区块链中的存储位置。获取目标签单信息对应的区块链存储标识，以该区块链存储标识在区块链中进行查找，获取目标哈希值。该目标哈希值指示了预先存储的正确的目标签单信息，可以作为验证依据用来与步骤S102中得到的目标签单信息进行比较。
S104，在以所述目标哈希值验证所述目标签单信息正确时，将所述目标签单信息发送给所述发货端。
例如，对所述目标签单信息进行哈希处理，得到待验哈希值。然后判断待验哈希值与目标哈希值是否一致。
若所述待验哈希值与所述目标哈希值一致，则确定所述目标签单信息正确。将确定正确的所述目标签单信息发送给所述发货端，同时，还可以同时将验证正确的结果或凭证发给发货端。
若所述待验哈希值与所述目标哈希值不一致，则确定所述目标签单信息有误。可以向发货端和业务***返回验证错误的提示信息，以提示业务***进行错误处理。
本实施例提供的一种基于区块链的签单返还方法，通过获取发货端发出的签单返还请求；根据所述签单返还请求，获取预存储的目标签单信息；从区块链中获取所述目标签单信息对应的目标哈希值；在以所述目标哈希值验证所述目标签单信息正确时，将所述目标签单信息发送给所述发货端，实现对目标签单信息的不可篡改的区块链存储，在提高签单返还的效率的同时，还提高了签单返还的可靠性。
在上述实施例的基础上，步骤S102之前或者步骤S101之前，还可以进行运单信息创建、同步和更新的过程，其实现方式可以有多种，下面结合附图和具体实施例进行举例和说明。
参见图3，是本发明实施例提供的另一种基于区块链的签单返还方法流程示意图，在图3所示方法包括步骤S201至步骤S206，具体如下：
S201，根据订单信息、预设的发货签名信息和运单实时状态信息，创建或更新过程运单信息，其中，所述过程运单信息包括第一运单信息、第二运单信息或者签单信息，所述运单实时状态信息包括：出单状态、运输状态或签收状态。
随着货物状态信息的变更，过程运单信息可以有多种状态，例如过程运单信息可以包括没有写入收货签名信息的第一运单信息和第二运单信息，以及写入了收货签名信息的签单信息。***服务器根据订单信息、预设的发货签名信息和运单实时状态信息，实现过程运单信息的创建和更新。其中，更新的实质步骤可以是在其他终端上完成的，而由***服务器进行接收、验证以及存储。所述发货签名信息例如包括预设的发货数字证书、预设的发货数字签名。
在一些实施例中，过程运单信息包括签单信息。步骤S201中对过程运单信息的更新方式可以有多种，一种实现方式例如可以是：派件员投递货物时，需要向收件用户提供运单二维码，则通过物流端向***服务器发出签单请求。***服务器在接收到物流端发出的签单请求时，向所述物流端发送第二运单信息，以使得所述物流端在验证所述发货签名信息正确时，根据所述第二运单信息向收货端提供用于指示所述第二运单信息的编码图像，其中，所述第二运单信息包括指示运输状态的运单实时状态信息、所述订单信息、所述发货签名信息。这里的编码图像例如是二维码图像。所述发货签名信息例如包括预设的发货数字证书、预设的发货数字签名。物流端验证发货签名信息正确的过程，例如是发货方预先通过权威认证中心为其数字身份(公钥、私钥)进行背书，证明公钥对应的持有人就是签名本人，并通过手机号实名、银行卡、面部比对、手持身份证等方式确保签名账号的真实性并且合规，实现发货数字证书的背书，然后在物流端收到第二运单信息时，根据第二运单信息中的发货数字证书，向认证中心验证发货数字证书的有效性，再以确认有效 的发货数字证书验证发货数字签名的合法性。如果确认合法，则表明确认验证所述发货数字证书和所述发货数字签名正确。签名验证的过程本发明实施例不做限定。
在上述实施例中，收货端在扫描所述编码图像得到所述第二运单信息时，可以先验证发货签名信息的正确性。在发货签名信息包括预设的发货数字证书、预设的发货数字签名的实施例中，也可以是向认证中心验证发货数字证书的有效性，再以确认有效的发货数字证书验证发货数字签名的合法性。如果确认合法，则表明确认验证所述发货数字证书和所述发货数字签名正确。在确定验证正确后，则根据预存储的收货签名信息，获取签单信息。签单信息包括收货签名信息、所述第二运单信息和指示签收状态的运单实时状态信息。收货端将签单信息发送至***服务器。具体地，可以是收货端将签单信息发给物流端，再由物流端将签单信息转发给***服务器，也可以是收货端直接将签单信息发给***服务器。***服务器从收货端接收签单信息，并验证所述签单信息正确，由此完成运输状态变更至签收状态过程中，对过程运单信息的更新(由第二运单信息更新至签单信息)。
其中，验证所述签单信息正确的方式，可以是验证所述签单信息包括的所述收货签名信息正确，并确定所述收货签名信息指示的身份信息与所述订单信息中指示的收件人信息匹配，其中，所述收货签名信息包括收货数字证书和收货数字签名，所述收货数字签名与收货端用户信息绑定。例如是收货用户预先通过权威CA中心为其数字身份(公钥、私钥)进行背书，证明公钥对应的持有人就是签名本人，并通过手机号实名、银行卡、面部比对、手持身份证等方式确保签名账号的真实性并且合规，实现收货签名信息的背书。订单信息中指示的收件人信息例如是收件人的姓名、身份证号、人脸图像和/或手机号，而收货签名信息指示的身份信息是收件用户为收货签名预先在例如CA中心背书的信息。这里的身份信息与收件人信息的匹配可以理解为比对一致。例如，只要从张三的手机端发出的收货签名信息，验证有效并与张三背书的签名信息验证正确，***服务器就可以认为收货方就是张三本人。***服务器通过数字签名，实现快速验签。
另一种实施例中，过程运单信息包括第一运单信息和第二运单信息。所述发货签名信息例如包括预设的发货数字证书、预设的发货数字签名。步骤 S201中，对过程运单信息的创建和更新方式可以有多种。一种实现方式中，在接收到物流端发出的签单请求时，向所述物流端发送第二运单信息之前，还可以有第一运单信息创建的过程，和/或获取第二运单信息的过程。第一运单信息创建的过程例如是，***服务器根据订单信息、指示出单状态的运单实时状态信息、预设的发货数字证书、预设的发货数字签名，创建第一运单信息。其中，所述第一运单信息包括所述订单信息、所述指示出单状态的运单实时状态信息、所述预设的发货数字证书以及所述预设的发货数字签名。获取第二运单信息的过程，例如是所述在接收到物流端发出的签单请求时，向所述物流端发送第二运单信息之前，***服务器还将所述第一运单信息发送给物流端，以使得所述物流端在验证所述发货数字证书和所述发货数字签名正确时接收所述第一运单信息。***服务器还可以将创建得到的第一运单信息存储在本地或云存储单元中，这里的第一运单信息可以理解为出单状态对应运单的内容信息，例如可以包括业务订单标识(例如业务***中的订单号)、运单标识(例如运单号)、发货方标识(例如卖家名称)、下单日期、承运方标识(例如快递公司名称)等信息。物流端在接收到第一运单信息后，进行处理、对第一运单信息对应的货物进行入库、出库、运输等操作，并在运输状态变更时，向***服务器发送第二运单信息。***服务器从所述物流端接收到第二运单信息，其中，所述第二运单信息为所述物流端根据运输状态对所述第一运单信息中的运单实时状态信息更新后的运单信息。这里的运输状态例如可以是入库、出库、运输位置等信息，可以由物流端根据实际情况进行设置。
S202，将所述过程运单信息进行存储，并将所述过程运单信息的哈希值存储入区块链。
***服务器在生成或接收到上述各种实施例中的过程运单信息时，同时进行本地或云端的存储，以及区块链的哈希值存储。
具体地，例如在接收到签单信息并验证所述签单信息正确时，将所述签单信息进行存储，并将所述签单信息的哈希值存储入区块链。
又例如，在创建得到的第一运单信息时，将创建得到的第一运单信息的哈希值存储入所述区块链。
再例如，在接收到第二运单时，将第二运单信息进行存储，并将所述第 二运单信息的哈希值存储入所述区块链。
通过将各个状态的过程运单信息的哈希值存储入区块链，利用区块链存储信息的不可篡改特性，实现了哈希值的可靠存储。
S203，获取发货端发出的签单返还请求。
S204，将与所述签单返还请求相对应的签单信息作为目标签单信息。
在上述获取到签单信息的实施例中，可以将与所述签单返还请求相对应的签单信息作为目标签单信息。
S205，从区块链中获取所述目标签单信息对应的目标哈希值。
S206，在以所述目标哈希值验证所述目标签单信息正确时，将所述目标签单信息发送给所述发货端。
图3所示实施例中的步骤S203至步骤S206的实现方式和技术效果，与图2所示步骤S101至S104类似，此处不再赘述。
本实施例通过在物流过程中，以区块链记录过程运单信息的创建和更新，并以数字签名提高过程运单信息传输过程的可靠性，为签单返还中的查验提供了数据基础，提高了最终得到的签单信息的可靠性。
参见图4，是本发明实施例提供的一种基于区块链的签单返还装置结构示意图，图4所示的基于区块链的签单返还装置40包括：
请求接收模块41，用于获取发货端发出的签单返还请求。
第一查找模块42，用于根据所述签单返还请求，获取预存储的目标签单信息。
第二查找模块43，用于从区块链中获取所述目标签单信息对应的目标哈希值。
返还处理模块44，用于在以所述目标哈希值验证所述目标签单信息正确时，将所述目标签单信息发送给所述发货端。
本发明提供的一种基于区块链的签单返还装置，通过获取发货端发出的签单返还请求；根据所述签单返还请求，获取预存储的目标签单信息；从区块链中获取所述目标签单信息对应的目标哈希值；在以所述目标哈希值验证所述目标签单信息正确时，将所述目标签单信息发送给所述发货端，实现对目标签单信息的不可篡改的区块链存储，在提高签单返还的效率的同时，还提高了签单返还的可靠性。
