Description
本申请要求2019年05月13日递交的申请号为201910400237.1、发明名称为“信息处理方法及设备”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。
本申请涉及计算机技术领域,尤其涉及一种信息处理方法及设备。
在跨境贸易中,提单是用以证明海上货物运输合同和货物已经由承运人接收或装船,以及承运人保证已交付货物的单证,作为物权凭证及其重要,并且具有金融资产属性,可用于质押融资。
当前,在国内提单都是通过纸质合同方式提供。这种纸质合同方式,存在以下几个严重问题:
一是流转成本高效率低,一般流转方式是出口商收到货款后通过快递寄送的方式寄给进口商,国际快递费用昂贵(每单平均100美金,平时耗时5到10天),而且整个过程中还可能存在纸质证书被破坏、丢失的情况;
二是修改困难,一旦内容需要进行修改往往需要跨国往返寄送,即送回原提单注销再签发新提单,低效且高成本。
三是船公司会开具一式三份提单,任何一份提单都可以作为提货凭证,不同人持有的情况下往往容易出现纠纷,而且持有人可能会使用不同份提单向不同银行进行多次重复质押,导致银行蒙骗受损。

在介绍本申请各实施例提供的技术方案之前,先对本文中涉及到的专有名词进行简单的介绍。
区块链(Blockchain):是分布式数据存储、点对点传输、共识机制、加密算法等计 算机技术的新型应用模式。区块链是比特币的一个重要概念,它本质上是一个去中心化的数据库,同时作为比特币的底层技术,是一串使用密码学方法相关联产生的数据块,每一个数据块中包含了一批次比特币网络交易的信息,用于验证其信息的有效性(防伪)和生成下一个区块。
多重签名(multi-signature):是多个用户对同一个消息或信息进行数字签名。在数字签名应用中,有时需要多个用户对同一个文件进行签名和认证。比如,一个公司公布的声明中涉及财务部、开发部、销售部、售后服务部等等部门,需要得到这些部门签名认可,那么就需要这些部门对这个声明文件进行签名,能够实现多个用户对同一文件进行签名的数字签名方案称作多重数字签名方案。
以跨境贸易领域为例,提单需货运公司(如船运、陆运或航运公司)、出口商和进口商共同签名。其中,提单(Bill of Lading)是指用以证明海上、陆运或空运货物运输合同和货物已经由承运人接收或者装船,以及承运人保证据以交付货物的单证。在对外贸易中,提单是运输部门承运货物时签发给发货人(可以是出口商,也可以是货代公司)的一种凭证。收货人(如进口商)凭提单向货运目的地的运输部门提货(若收货人手里是小单,则需要向国内货代换取主单),提单须经承运人或船方签字后始能生效。
为了使本技术领域的人员更好地理解本申请方案,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。
在本申请的说明书、权利要求书及上述附图中描述的一些流程中,包含了按照特定顺序出现的多个操作,这些操作可以不按照其在本文中出现的顺序来执行或并行执行。操作的序号如101、102等,仅仅是用于区分各个不同的操作,序号本身不代表任何的执行顺序。另外,这些流程可以包括更多或更少的操作,并且这些操作可以按顺序执行或并行执行。需要说明的是,本文中的“第一”、“第二”等描述,是用于区分不同的消息、设备、模块等,不代表先后顺序,也不限定“第一”和“第二”是不同的类型。另外,下文所描述的实施例仅仅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,都属于本申请保护的范围。
图1示出了本申请一实施例提供的信息处理系统的结构示意图。具体的,如图所示,所述信息处理系统包括:
客户端101,用于接入服务端102中的第一计算节点,获取等待多参与方达成共识的第一信息;将所述第一信息发送至所述第一计算节点;
所述服务端102,其基于区块链构建,所述区块链包括多个计算节点(如图1中的P1~P6);
所述第一计算节点P1、P2、P3或P4,用于将所述第一信息的状态置为第一状态,基于所述第一信息及所述第一状态,生成向所述服务端102(可以是电子提单区块链平台)中的至少一个第二计算节点发送有关所述第一信息需达成多方共识的通知,以通知与所述第一信息相关的参与方接入的第二计算节点为达成共识协同对所述第一信息进行处理。
图1仅示出了区块链中包含六个计算节点的示例,实际应用中,计算节点的数量还可以是3个、5个或更多,本实施例对此不作具体限定。
以跨境贸易中的电子提单来说,客户端可包括:运输公司侧客户端(如船公司内部系统)、出口方客户端(如手机APP)及进口方客户端(如手机APP)。其中,运输公司可以是船运公司、航运公司或路运公司等等;出口方可以是出口商或货物代理公司等;进口方可以是进口商或进口商走信用证的银行等等。客户端可以是集成在终端上的一个具有嵌入式程序的硬件,也可以是安装在终端中的一个应用软件,还可以是嵌入在终端操作系统中的工具软件等,本申请实施例对此不作限定。该终端可以为包括手机、平板电脑、PDA(Personal Digital Assistant,个人数字助理)、POS(Point of Sales,销售终端)、车载电脑等任意终端设备。
假设本实施例中第一信息是运输公司人员(如图1中的第一用户)通过客户端(即船公司系统)创建的电子提单,运输公司客户端接入的第一计算节点是图1中P2的节点;该电子提单需运输公司、进口方和出口方共同签名方能生效。出口方客户端和进口方客户端各自接入计算节点分别是图1中的P1和P3节点。此时,即需要P1、P2和P3三个计算节点协同对该电子提单进行处理(即签名处理)以表征三方以对该电子提单达成了共识。
达成共识的前提是三方均对电子提单的内容无异议,然后使用能唯一代表各方的加密参数(如私钥)对电子提单进行加密(如数字签名处理)。具体实施时,各方在对电子提单进行处理之前,可对电子提单进行校验,如签名校验(以校验该电子提单是否来源于约定发起方)、内容校验(以校验提单内容是否被篡改)、哈希值校验等等。在一种可实现的技术方案中,对电子提单的校验和处理可均有客户端接入的计算节点完成;或者对电子提单的校验由客户端接入的计算节点完成、对电子提单的处理可由客户端完成;或者对电子提单的校验和处理均由客户端完成、客户端接入的计算节点完成对电子 提单处理结果的广播等。
本实施例提供的技术方案,通过区块链技术实现需多方达成共识的信息(如合同、提单等)数字化,从而避免了纸质证书带来的造假、流转费用高、流转效率低、可能被破坏或丢失的问题。接入区块链中各计算节点的多个参与方可对同一信息(如电子合同、提单)进行协同处理(如对电子合同或电子提单进行多重签名);另外,任一参与方对该信息的处理操作均可记录在区块链中,实现区块链上信息的实时查验,避免信息被重复使用,保证信息的唯一性,保证多方达成共识的信息不被篡改。
这里需要说明的是,本申请实施例提供的信息处理系统中各组成单元,例如客户端、服务端中的各计算节点的具体工作流程可参见上述各实施例中相应内容,在此不再赘述。
图2示出了本申请一实施例提供的信息处理方法的流程示意图。本申请实施例提供的所述方法的执行主体可以上述系统中的客户端,如在跨境贸易中的运输方客户端、进口方客户端或出口方客户端。如图2所示,所述信息处理方法,包括(步骤201到步骤203):
201、接入服务端中的第一计算节点;其中,所述服务端基于区块链构建,所述区块链包括多个计算节点。
202、获取等待多参与方达成共识的第一信息。
203、将所述第一信息发送至所述第一计算节点,以由所述第一计算节点及所述服务端中的至少一个第二计算节点,为达成共识协同对所述第一信息进行处理。
其中,与第一信息相关的参与方接入第二计算节点。所述区块链中的计算节点上部署有智能合约程序;所述第一计算节点及与所述至少一个第二计算节点,通过所述智能合约程序协同完成对所述第一信息的处理。其中,智能合约旨在以信息化方式传播、验证或执行合同的计算机协议。智能合约允许在没有第三方的情况下进行可信交易,这些交易可追踪且不可逆转。智能合约程序是基于区块链的,并且会在区块链检测到某些特定数据条件下时会触发。本文各实施例中提及的由计算节点完成的处理操作均可简单理解为:是由智能合约程序执行完成。
上述步骤201中,服务端,亦或称区块链平台,提供接入平台,接入平台对各客户端提供API(Application Programming Interface,应用程序编程接口)访问、Web页面访问等,接入平台可通过SDK(Software Development Kit,软件开发工具包)与区块链平台(即区块链中的计算节点)进行交互。以跨境贸易应用场景为例,运输方客户端、 出口方客户端、进口方客户端都部署有自己的接入平台,然后通过自己部署的接入平台接入区块链中的一个计算节点,然后各客户端把自己的业务系统通过API方式对接接入平台,通过接入平台与各自接入的计算节点交互,也可以直接通过web方式访问接入平台。各客户端则可通过任一接入平台提供的无线服务使用终端上安装的应用程序(APP)接入。
即在一种可实现的技术方案中,本步骤201“接入服务端中的第一计算节点”可包括:
通过所述服务端提供的API接口接入所述第一计算节点;或者
通过访问所述服务端提供的网络页面的方式接入所述第一计算节点。
上述步骤202中,等待多参与方达成共识的第一信息可以是用户通过客户端提供的创建功能新创建的,也可以是用户通过客户端提供的修改功能对历史信息进行修改后得到的。第一信息可以是待多参与方达成共识的电子合同;实际上,电子提单也可以理解为是电子合同的一种。
在一具体应用场景如跨境贸易场景中,电子提单需三方签名,本实施例提供的所述方法的执行主体可以是电子提单发起方客户端。
场景1、发起方新创建第一信息
本步骤202“获取等待多参与方达成共识的第一信息”,可具体包括:
响应于用户触发的信息创建事件,根据所述创建事件中产生的创建内容,生成所述第一信息;或者
响应于用户触发的信息创建事件,对所述创建事件中产生的创建内容进行校验,在所述创建内容通过校验的情况下,根据所述用户的私钥及所述创建内容,得到所述第一信息。
具体实施时,上述实施例提供的信息处理系统还包括CA认证机构。CA认证机构为每个参与方发放实名认证的CA证书,CA证书包含一对唯一的公私钥,公钥是每个参与方的唯一标识,用于对自己的交易进行签名验证,私钥用于对自己发出的交易进行签名。
由此,上述“根据所述用户的私钥及所述创建内容,得到所述第一信息”,可具体包括:
基于创建内容得到中间信息;
使用所述用户的私钥,对所述中间信息进行签名得到第一信息。
这里需要说明的是:使用私钥对信息进行签名的过程,以及后续出现的使用公钥验 证信息的过程,均可参见现有技术的数字签名技术,本文对此不作赘述。
场景2、发起方修改电子提单并请求其他参与方确认签名
响应于用户触发的针对一历史信息的修改事件,将修改后的所述历史信息作为所述第一信息;或者
响应于用户触发的针对一历史信息的修改事件,对修改后的所述历史信息进行与内容相关的校验,在修改后的所述历史信息通过校验的情况下,根据所述用户的私钥及修改后的所述历史信息,得到所述第一信息。
其中,上述“根据所述用户的私钥及修改后的所述历史信息,得到所述第一信息”,包括:
使用所述用户的私钥,对修改后的所述历史信息进行签名得到所述第一信息。
本实施例提供的技术方案,通过区块链技术实现需多方达成共识的信息(如合同、提单等)数字化,从而避免了纸质证书带来的造假、流转费用高、流转效率低、可能被破坏或丢失的问题。接入区块链中各计算节点的多个参与方可对同一信息(如电子合同、提单)进行协同处理(如对电子合同或电子提单进行多重签名);另外,任一参与方对该信息的处理操作均可记录在区块链中,实现区块链上信息的实时查验,避免信息被重复使用,保证信息的唯一性,保证多方达成共识的信息不被篡改。
上述步骤201~203提供的技术方案,是在执行主体为第一信息的发起方(如运输方)的角度。实质上,本实施例提供的技术方案的执行主体也可作为被动方,例如,被请求对第二信息进行签名的出口方或进口方。即本实施例提供的所述方法还可以包括:
204、接收所述第一计算节点发送的等待多参与方达成共识的第二信息。
假设,一用户通过客户端创建第二信息,该客户端将该第二信息发送至其接入的第二计算节点,第二计算节点针对该第二信息进行广播或将第二信息发送至与第二信息相关(如存在利益关系)的第一计算节点。第一计算节点接收到该第二信息后,会将该第二信息发送至接入其的客户端(即本步骤的执行主体)。
205、响应于用户针对所述第二信息触发的处理指示,向所述第一计算节点反馈与所述处理指示相关的消息,以使所述第一计算节点对所述第二信息进行相应的处理,并广播对所述第二信息的处理结果。
上述步骤204中,假设第二计算节点在区块链的多个计算节点中广播,或第二计算节点向所述第一计算节点发送接入第二计算节点的参与方发起的交易(如电子合同、电子提单等),第一计算节点接收到所述等待多方参与达成共识的第二信息后,可先对第 二信息进行校验,在所述第二信息通过校验的情况下,第一计算节点再将该第二信息发送至接入其的客户端,即本步骤204的执行主体。
其中,对第二信息进行的校验可包括:签名校验、内容校验及哈希值校验中的任一种或多种。具体实施时,签名校验的目的是为了验证第二信息是否来源于接入第二计算节点的参与方,即验证第二信息的签名是否由接入第二计算节点的参与方使用自己的私钥完成的。这里需要说明的是:本文中使用私钥对信息进行签名的过程,以及验证签名的过程可参见现有技术中的数字签名技术,本文对此不作赘述。内容校验可以是对某一个或某几个字段是否符合预设字段填写规则的校验,假设第二信息为电子提单,则电子提单中的金额字段内的数字是否符合预设金额范围;超出所述预设金额范围,则该电子提单未通过内容校验;未超出所述预设金额范围,若还有其他字段的校验,且其他字段均通过校验,则电子提单通过校验。对第二信息的哈希值校验也可参见现有相关技术,本文对此不作赘述。
在另一种可实现的方案中,对第二信息的校验也可由客户端来完成,即第一计算节点仅起到转发信息的作用。即本实施例提供的所述方法还可包括如下步骤:
206、对所述第二信息进行校验;
207、在所述第二信息通过校验的情况下,为所述用户赋予能对所述第二信息进行处理指示的权限;
其中,对所述第二信息进行的校验包括如下至少一种:签名校验、内容校验及哈希值校验。
上述步骤207中,在用户来看,用户具有对第二信息进行处理指示的权限,可表现在:用户在客户端界面上针对第二信息进行相应处理指示的操作,客户端会作出相应的响应。比如,客户端界面上显示有第二信息,用户可在手机、电脑等上查看第二信息,确认第二信息无误的情况下,客户端界面上的确认签名控件和拒绝签名控件处于可点击状态,用户可通过触控确认签名控件或拒绝签名控件对第二信息做出确认签名的指示或拒绝签名的指示;客户端会根据用户的处理指示,使用所述用户的私钥对第二信息进行签名并向客户端接入的第一计算节点发送已签名完成的第二信息或者向客户端接入的第一计算节点发送用户拒绝签名的消息。
用户不具有对第二信息进行处理指示的权限,可表现在:用户在客户端界面上针对第二信息进行相应处理指示的操作,客户端不会做任何相应。例如,客户端界面上显示有第二信息,用户可在手机、电脑等上查看第二信息,但客户端界面上的确认签名控件 和拒绝签名控件处于不可点击状态(如灰度显示),用户无法触控这些控件。
在一种可实现的技术方案中,所述处理指示包括:确认签名指示和拒绝签名指示。相应的,上述步骤205中“响应于用户针对所述第二信息触发的处理指示,向所述第一计算节点反馈与所述处理指示相关的消息”,可具体包括:
响应于用户针对所述第二信息触发的确认签名指示,使用所述用户的私钥对所述第二信息进行签名;将签名后的所述第二信息携带在向所述第一计算节点反馈的消息中;
响应于用户针对所述第二信息的拒绝签名指示,向所述第一计算节点反馈所述用户拒绝对所述第二信息签名的消息。
再进一步的,本实施例中除对第二信息进行校验,在第二信息通过校验的情况下,为所述用户赋予能针对所述第二信息触发处理指示的权限之外,还可增加对第二信息当前的所有权的验证,即本实施例提供的所述方法,还可包括如下的步骤:
208、获取能表征所述第二信息所属用户的参数。
209、根据所述参数,确定所述第二信息的所有权是否属于所述用户。
210、在确定所述第二信息的所有权属于所述用户的情况下,为所述用户赋予能针对所述第二信息触发处理指示的权限。
其中,第二信息中携带有能表征其所属用户的参数,如其所属用户的公钥。因此,上述步骤208中,可直接从所述第二信息中获取到该参数,即公钥。
上述步骤209中,假设所述参数为第二信息所属用户的公钥,如出口方的公钥;而上述步骤208~210的执行主体为出口方客户端;相应的,上述步骤209可具体为:比较所述第二信息所属用户的公钥是否与执行主体(如出口方客户端)的公钥相同,若相同,则说明此时第二信息的所有权在出口方,出口方的用户可通过出口方客户端对第二信息进行操作,如对第二信息进行签名等;若不同,则说明第二信息的所有权不在出口方,出口方的用户不能通过出口方客户端对第二信息进行任何操作,如对第二信息进行签名等。
在实际业务场景中,电子提单的所有权需进行转移,比如,出口方收到进口方或进口方通过走信用证的银行的货款后,此时电子提单的所有权应转移给进口方,进口方持电子提单到提货地点取货时,运输方人员需查验当前来提货的进口方是否拥有该电子提单的所有权,只有确认进口方具有该电子提单的所有权才能让进口方提取该电子提单对应的货物。即本实施例提供的所述方法,还可包括如下步骤:
211、响应于用户针对第三信息触发的所有权转移事件,获取所述用户欲转移的目标 对象;其中,所述用户具有所述第三信息的所有权;
212、根据所述目标对象,对所述第三信息进行所有权修改;
213、将所有权修改后的所述第三信息发送至所述第一计算节点,以由所述第一计算节点针对所有权修改后的所述第三信息进行广播。
为了方便理解,结合具体应该场景,如跨境贸易场景,上述步骤211~213的执行主体可以是出口方客户端;用户为出口商。出口商可通过出口方客户端对第三信息进行所有权转移操作;例如,出口方客户端的交互界面上显示有所有权转移控件,用户点击该所有权转移控件后,显示有一个或多个用户具有所有权的一个或多个信息(如电子提单),用户选出一个目标信息(即上述步骤中提及的第三信息),然后为其配置欲转移的目标对象(如进口商的标识,可以是公司名称、代号等等)。用户完成上述所有所有权转移操作后,即会触发针对所述第三信息的所有权转移事件。
在一具体实现方案中,上述“根据所述目标对象,对所述第三信息进行所有权修改”可包括:
2121、获取所述目标对象的公钥。
2122、将所述第三信息中包含的所述用户的公钥修改为所述目标对象的公钥。
或者,上述修改第三信息所有权的操作可由本实施例执行主体(即客户端)接入的第一计算节点来完成。即本实施例提供的所述方法,可包括如下步骤:
214、获取拥有所有权的第三信息。
215、响应于用户针对第三信息触发的所有权转移指示,获取所述用户指示的目标对象。
216、向所述第一计算节点发送将所述第三信息的所有权转移至所述目标对象的消息,以由所述第一计算节点根据所述目标对象,对所述第三信息进行所有权修改,并针对所有修改后的所述第三信息进行广播。
在实际业务场景中,具有电子提单所有权的进口商,还需进行提单提货申请。进口商提出提单提货申请后,运输方需对该电子提单的所有权是否属于进口商、当前电子提单的状态是否可用进行验证。这里需要说明的是:为了便于对区块链平台上的大量电子提单的管理,除要实时的明确电子提单的所有权,区块链平台上的计算节点还需实时根据其对电子提单的处理,更新电子提单的状态,比如,所有参与方均完成对电子提单的签名,则将该电子提单的状态置为生效状态或合法状态;若所有参与方中有一个参与方拒绝对电子提单进行签名,则将该电子提单的状态置为非法状态等等。这里需要说明的 是:有关区块链平台上各计算节点如何维护电子提单的内容,将在后续实施例中详细说明。即本实施例提供的所述方法还可包括:
217、接收所述第一计算节点发送的针对第四信息的执行申请,其中,所述执行申请是由参与方触发,并由所述参与方接入的第二计算节点发出;由所述第一计算节点接收到后转发。
218、对所述第四信息进行校验,以输出所述第四信息是否可执行的校验结果,作为判断提出所述执行申请的参与方是否具有对所述第四信息进行相应执行动作的依据。
货物到港后,进口方进行提单提货申请,运输方收到该提单提货申请后,对进口方申请执行(即提货)的电子提单进行校验,如校验该进口商是否具有该电子提单的所有权、该电子提单的状态是否可用等。比如,电子提单的状态是合法状态时,认为该电子提单可用;该电子提单是非法状态或注销状态,则认为该电子提单不可用。
即上述步骤218“对所述第四信息进行校验,以输出所述第四信息是否可执行的校验结果”,可具体包括:
2181、对所述第四信息进行所有权校验,以校验所述第四信息所属用户是否是提出执行申请的参与方;
2182、获取所述第四信息对应的状态信息,基于所述状态信息校验所述第四信息是否为可执行信息;
2183、在所述第四信息通过所述所有权校验,且所述第四信息为可执行信息的情况下,所述第四信息通过校验,输出提出所述执行申请的参与方具有对所述第四信息进行相应执行动作的校验结果;
2184、在所述第四信息未通过所述所有权校验或所述第四信息为不可执行信息的情况下,所述第四信息未通过校验,输出提出所述执行申请的参与方不具有对所述第四信息进行相应执行动作的校验结果。
该提出所述执行申请的参与方具有对所述第四信息进行相应执行动作的校验结果可显示在运输方客户端;这样运输方客户端可通过界面上显示的校验结果,决定是否让进口方提货。若校验结果是:提出所述执行申请的参与方具有对所述第四信息进行相应执行动作,则运输方人员可允许进口方提货,并在确认进口方完成提货后,通过运输方客户端对该电子提单进行注销操作。即本实施例提供的所述方法,还可包括如下步骤:
219、响应于用户针对所述第四信息的注销事件,向所述第一计算节点发送注销所述第四信息的消息,以由所述第一计算节点对所述第四信息进行注销操作,并针对所述第 四信息被注销进行广播。
具体实施时,对所述第四信息进行注销操作可具体为:将第四信息的状态置为注销状态,假设表征注销状态的参数为400,即将第四信息对应的状态参数置为400,并针对第四信息被注销进行广播。其中,广播的目的是:让区块链中每个计算节点都同步将第四信息的状态置为注销状态。这是区块链的一大特点,在其中一个计算节点对某一信息进行了操作,如所有权转移或重置状态等,全网均会同步更新该信息的所有权或重置的状态。
图3示出了本申请一实施例提供信息处理方法的流程示意图。本实施例提供的所述方法的执行主体可以是区块链中的任一计算节点。其中,计算节点可以是一台具有计算能力的计算机,还可以是部署在集群服务器中的一个虚拟设备等等。具体的,如图3所示,所述方法包括(步骤301至步骤303):
301、获取第一接入客户端发送的等待多参与方达成共识的第一信息。
302、将所述第一信息的状态配置为第一状态。
303、基于所述第一信息及所述第一状态,发出有关所述第一信息需达成多方共识的通知,以与服务端中接收到所述通知的至少一个第二计算节点,为达成共识协同对所述第一信息进行处理。
其中,所述服务端基于区块链构建,所述区块链包括多个计算节点,与第一信息相关的参与方接入第二计算节点。
上述步骤301中,所述第一信息是用户通过所述第一接入客户端创建的;或者,所述第一信息是用户通过所述第一接入客户端对历史信息进行修改后的得到的。例如,第一接入客户端为用户提供了信息创建功能,比如,与具体业务对应的表格,用户只需要按照表格填写相应字段内容即可完成创建;用户填写完后,通过触控客户端界面上的“提交”或“创建”等控件,即可完成第一信息的创建。或者,第一接入客户端为用户提供了对历史上的某一信息的修改功能,第一接入客户端调出用户欲修改的历史信息并显示为可编辑状态,用户即可在第一接入客户端的交互界面上对历史进行修改,并在修改后,通过触控客户端界面上的“提交”等控件,即完成修改得到第一信息。
上述步骤302中,所述第一状态可以是初始状态,具体实施时,可采用参数来表征第一信息的状态,例如,第一状态对应的参数为0,第二状态对应的参数为200,第三状态对应的参数为300等等;各状态对应的参数可基于实际情况设定,本实施例对此不作 具体限定。
在实际业务场景中,如跨境贸易中的电子提单,会处于不同的业务阶段,因此为了维护区块链中各区块记录的电子提单所处的业务阶段,计算节点基于当前电子提单所处阶段,为电子提单配置相应的状态,以方便区块链所有计算节点实时获知该电子提单所处的业务阶段。发起方刚发起新创建的电子提单时,该电子提单即处于本实施例中的第一状态(即等待其他参与方签名);当所有参与方都完成了对第一信息的签名后,此时,第一信息的状态可置为第二状态(亦或称合法状态);当有参与方拒绝对第一信息进行签名时,第一的状态可置为第三状态(亦或称非法状态);当有参与方发起执行该第一信息(如电子提单提货)的申请,且该参与方完成该第一信息的执行事件(如已完成提货)时,第一信息的状态可置为第四状态(亦或称注销状态)。上述各状态可分别用不同的数值来表示,本实施例对此不作具体限定。
在一种可实现的方案中,上述步骤303中“基于所述第一信息及所述第一状态,发出有关所述第一信息需达成多方共识的通知”,可具体包括:
3031、对所述第一信息进行校验;其中,校验包括如下中的至少一种:签名校验、内容校验与哈希值校验。
3032、在所述第一信息通过校验的情况下,获取使用所述第一接入客户端的用户的私钥。
3033、使用所述私钥对所述第一信息进行签名。
3034、根据签名后的所述第一信息及所述第一状态,广播所述通知或向所述服务端中与所述第一信息有关的至少一个第二计算节点发送所述通知。
这里需要说明的是:上述步骤3031~3033也可由接入计算节点的客户端(即本实施例步骤301中的第一接入客户端)来执行。
上述步骤3034中,所述通知中可携带有签名后的所述第一信息及第一信息对应的第一状态。
在一具体实施方案中,上述步骤3031中“对所述第一信息进行内容校验”包括:
获取字段校验规则,其中,所述字段校验规则中包含至少一字段规则项;
基于所述字段校验规则,对所述第一信息中包含的字段内容是否符合所述字段校验规则中相应字段规则项;
在所述第一信息中包含的所有字段内容都符合各自对应的字段规则项的情况下,所述第一信息通过与内容有关的校验;
在所述第一信息中含有一个字段内容不符合其对应的字段规则项的情况下,所述第一信息未通过与内容有关的校验。
举例来说,字段校验规则有一个字段规则项为交易金额范围。若第一信息中金额字段的金额数值未超过该交易金额范围,则说明该金额字段符合该交易金额范围规则项。若第一信息中金额字段的金额数值超过该交易金额范围,则第一信息就不能通过与内容有关的校验。
本实施例提供的技术方案,通过区块链技术实现需多方达成共识的信息(如合同、提单等)数字化,从而避免了纸质证书带来的造假、流转费用高、流转效率低、可能被破坏或丢失的问题。接入区块链中各计算节点的多个参与方可对同一信息(如电子合同、提单)进行协同处理(如对电子合同或电子提单进行多重签名);另外,任一参与方对该信息的处理操作均可记录在区块链中,实现区块链上信息的实时查验,避免信息被重复使用,保证信息的唯一性,保证多方达成共识的信息不被篡改。
进一步的,本实施例提供的所述方法还可包括如下步骤:
304、接收第二计算节点发出的与所述第一信息相关的状态更新通知,其中,所述状态更新通知是所述第二计算节点根据接入其的第二接入客户端对所述第一信息的处理指示,对所述第一信息进行相应处理;并基于处理结果修改所述第一信息对应的状态信息后发出的。
305、将本地记录的所述第一信息对应的所述第一状态更新为所述状态更新通知指定的目标状态。
上述步骤304~305,会出现在第二计算节点对第一信息进行处理后,此时第一信息的状态发生变化的场景。例如,第二计算节点对第一信息进行签名后,且基于与第一信息相关的数据,判定所有相关利益方均完成对第一信息的签名的情况下,第二计算节点将第一信息的状态从第一状态更新为第二状态;或者,第二计算节点接收到接入第二客户端拒绝对第一信息进行签名的指示后,第二计算节点将第一信息的状态从第一状态更新为第三状态;等等。
进一步的,本实施例提供的所述方法还可包括如下步骤:
306、接收到第二计算节点发出的等待多方达成共识的第二信息后,向所述第一接入客户端发送针对所述第二信息需参与共识处理的消息;

308、根据所述处理指示,对所述第二信息进行相应处理;
309、广播对所述第二信息的处理结果或向所述服务端中与所述第一信息有关的至少一个第二计算节点发送所述处理结果。
具体实施时,所述处理指示可包括:确认签名指示和拒绝签名指示。相应的,上述步骤308可具体包括:
3081、在所述处理指示为确认签名指示的情况下,获取使用所述第一接入客户端的用户的私钥;使用所述私钥对所述第二信息进行签名;获取本地记录的与所述第一信息相关的关联信息,基于所述关联信息,判断是否所有约定参与方都完成对所述第一信息的签名;若判断是,则将所述第二信息的状态信息置为第二状态;
3082、在所述处理指示为拒绝签名指示的情况下,将所述第二信息的状态信息置为第三状态。
进一步的,本实施例提供的所述方法还可包括如下步骤:
310、接收第一接入客户端发送的将第三信息的所有权转移至目标对象的消息;
311、根据所述目标对象,对所述第三信息进行所有权修改;

315、向所述第一接入客户端发送所述第四信息是否可执行的校验结果,以作为判断提出所述执行申请的参与方是否具有对所述第四信息进行相应执行动作的依据。
在一种可实现的技术方案中,上述314“对所述第四信息是否可执行进行校验”,可包括:
对所述第四信息进行所有权校验,以校验所述第四信息所属用户是否是提出执行申请的参与方;
获取所述第四信息对应的状态信息,基于所述状态信息校验所述第四信息是否为可执行信息;
在所述第四信息通过所述所有权校验,且所述第四信息为可执行信息的情况下,所述第四信息通过校验,输出提出所述执行申请的参与方具有对所述第四信息进行相应执行动作的校验结果;
在所述第四信息未通过所述所有权校验或所述第四信息为不可执行信息的情况下,所述第四信息未通过校验,输出提出所述执行申请的参与方不具有对所述第四信息进行相应执行动作的校验结果。
进一步的,本实施例提供的所述方法还可包括如下步骤:
316、接收所述第一接入客户端发送的注销所述第四信息的消息。

继续参见图1所示的信息处理系统。该信息处理系统中所述多个计算节点中的一个计算节点(海关接入的计算节点),用于接收到服务端中另一个计算节点发出的共识信息通知后,获取本地存储的与所述共识信息相关的储备信息;基于所述储备信息,对所述共识信息进行校验;根据所述共识信息的校验结果,对所述共识信息进行相应的处理;客户端,用于接入服务端中的一个计算节点,接收所述计算节点发送的对共识信息的处理结果;显示所述处理结果。其中,所述共识信息为:至少两个参与方为对同一信息达成共识通过区块链网络中的至少两个计算节点协同对该信息进行处理后得到的。
若将上述系统套入一实际应用场景中,上述客户端可以是跨境贸易场景中海关侧客户端(如海关系统)。海关侧客户端具备对已达成共识信息进行校验的功能,当然具有信息协助验证、信息查询等功能。在一具体可实现的技术方案中,海关侧客户端对共识信息进行的校验可具体包括:使用三方(如运输方、进口方及出口方)的公钥对他们达成共识的共识信息进行验证,以验证该共识信息的签名是否是这三方签署的;签名验证通过后,在将该共识信息与本地备份的所述共识信息的储备信息,进行交叉校验(比如比较共识信息中商品数量是否与上报海关的数量相同)。如果通过交叉校验,则将该共识信息放入设定信息池(如交易池);如果未通过交叉校验,则将共识信息的状态置为第三状态(亦或称非常状态),并向区块链其他计算节点广播该共识信息的状态置为第三状态的消息。

本申请各实施例可适用于海运、陆运和空运电子提单数字化的场景。下面以海运为例,对本申请各实施例提供的技术方案进行说明。结合具体场景,更利于技术方案的理解。
图1信息处理系统结构图,参与方包括出口商(如图1中的第三用户)、进口商(如图1中的第二用户)、货代公司、海关(如图1中的第四用户)、船公司(如图1中的第一用户)和银行,另外还有CA认证机构。CA认证机构为每个参与方发放实名认证的CA证书,CA证书包含一对唯一的公私钥,公钥是每个参与方的唯一标识,用于对自己的交易进行签名验证,私钥用于对自己发出的交易进行签名。为了方便业务应用系统开发,区块链平台统一提供接入平台,接入平台对业务应用系统提供友好的API访问、Web页面访问和无线接入,接入平台通过SDK与区块链平台进行交互。船公司、海关、银行和货代公司都部署自己的接入平台和区块链节点,然后把自己的业务系统通过API方式对接接入平台。通过接入平台与区块链平台进行交互,也可以直接通过web方式访问接 入平台。出口商和进口商则通过任一接入平台提供的无线服务使用手机APP接入,直接在手机APP上进行提单查询、转移、修改提议、修改确认、提货申请等操作。
图10描述了各个参与方的功能和职责,以及区块链账本的基本构成。其中,出口商具备提单修改提议、提单修改确认、提单查询、提单转移等功能。进口商具备提单修改提议、提单修改确认、提单查询、提单转移、提单提货申请等功能。船公司具备提单修改提议、提单修改确认、提单签发、提单查询、提单提货验证等功能。货代公司具备提单协助验证、提单查询等功能;海关具备提单协助验证、提单查询等功能;银行具备提单转移和提单查询等功能。
一笔电子提单的提单交易包含的基本信息如下:
1、唯一提单编号
2、货物的品名、标志、包数或件数,或者重量或以其他方式表示的数量,如系危险货物,则对其危险性质的明确说明,这些资料均由托运人提供。
3、货物的外表形态
4、承运人名称及其主要营业所所在地。
5、托运人名称
6、托运人指定收货人时的收货人名称
7、船名,海上运输合同规定的装货港,以及货物由承运人在装运港接管的日期
8、海上运输合同规定的卸货港
9、提单签发地点
10、承运人及其代表的签字
11、收货人应付运费金额,或者应由收货人支付运费的其他说明
12、关于货物运输应遵守该规则各项规定,凡是于此相背离的,有损于托运人或收货人的条款均属无效的声明
13、货物应在或可在舱面装运的声明
14、经承运人与托运人明确协议的货物在卸货港的交付日期或期限
15、承运人与托运人约定的高于该规则的承运人责任限额
16、提单状态

图11描述了电子提单签发智能合约的原理,一张合法的电子提单必须由船公司、进口商、出口商三方同时签名才能生效。该电子提单可以是新创建的,也可以是对已有提单进行修改后得到的。
图11船公司发起签发电子提单,所以没有拒绝签名的权利,在发起电子提单签发的同时使用船公司自己的私钥对电子提单进行签名;船公司客户端接入计算节点A将已签名的电子提单的状态置为第一状态(如状态参数置为0);并在区块链中广播请求进口商和出口商对该电子提单进行签名的通知。
进口商接入的计算节点B接收到该通知后,计算节点B获取签有船公司签名的电子提单。计算节点B使用船公司的公钥对电子提单进行签名校验;同时对电子提单内容中的业务数据字段进行校验。签名验证和字段校验都通过的情况下,计算节点B将签有船公司签名的电子提单发送至进口商的客户端(如手机、电脑),这样进口商就可通过客户端看见电子提单的具体内容,以便对电子提单的内容作进一步的核对。进口商核对无误后,点击交互界面上的“签名”或“确认”控件。计算节点B接收到进口商触控“签名”或“确认”控件的消息后,对进口商确认签名的电子提单进行校验(比如关键字段的校验),校验通过后,使用进口商的私钥对电子提单进行签名,并全网广播。计算节点B上部署的智能合约还会记录进口商已对电子提单进行签名的信息。智能合约可通过获取本地记录的该电子提单的签名记录,判断所有相关参与方是否针对该电子提单达成共识(即均完成签名)。若判断出还有参与方未完成签名,则继续等待。若所有相关参与方均对电子提单进行了签名,则将该电子提单置为正式生效状态或合法状态(即上述各实施例中提及的第二状态,对应的参数假设为200),并放入本地交易池,并进行全网广播,以便区块链上的其他计算节点同步该电子提单的状态为合法状态。进口商核对发现电子提单内容有误,点击交互界面上的“拒绝”控件。计算节点B接收到进口商触控“拒绝”控件的通知后,计算节点B上部署的智能合约将该电子提单置为非法状态(即上文提及的第三状态,对应的参数假设为300),并进行全网广播。
出口商接入的计算节点C收到该通知后,计算节点C可先验证该电子提单的所有权是否为出口商的(即电子提单中所含的公钥是否是出口商的公钥)。验证通过后,同上述进口商接入的计算节点B类同,对电子提单进行签名校验、业务数据字段校验,…..等等。校验通过后,计算节点C将电子提单发送至处口商的客户端(如手机、电脑),这样出口商就可通过客户端看见电子提单的具体内容,以便对电子提单的内容作进一步的核对。出口商核对无误后,点击交互界面上的“签名”或“确认”控件。计算节点C 接收到出口商触控“签名”或“确认”控件的消息后,对出口商确认签名的电子提单进行校验(比如关键字段的校验),校验通过后,使用出口商的私钥对电子提单进行签名,并全网广播。计算节点C上部署的智能合约还会记录进口商已对电子提单进行签名的信息。智能合约可通过获取本地记录的该电子提单的签名记录,判断所有相关参与方是否针对该电子提单达成共识(即均完成签名)。若判断出还有参与方未完成签名,则继续等待。若所有相关参与方均对电子提单进行了签名,则将该电子提单置为正式生效状态或合法状态(即上述各实施例中提及的第二状态,对应的参数假设为200),并放入本地交易池,并进行全网广播,以便区块链上的其他计算节点同步该电子提单的状态为合法状态。出口商核对发现电子提单内容有误,点击交互界面上的“拒绝”控件。计算节点C接收到进口商触控“拒绝”控件的通知后,计算节点C上部署的智能合约将该电子提单置为非法状态(即上文提及的第三状态,对应的参数假设为300),并进行全网广播。
图1中的海关和货代公司接收到处于第二状态的电子提单(即合法状态的电子提单)的广播后,首先使用船公司、出口商和进口商,三个签名方的公钥对该电子提单的签名进行验证,签名验证通过后再对该提单的贸易数据与自己平台数据进行交叉校验(比如跟物流单据进行校验),如果合法则放入交易池,非法则将提单置为第三状态(亦或称非法状态,状态参数为300),并向全网广播。
出口商收到货款后发起一笔电子提单转移交易以将电子提单的所有权转移给进口商,并向全网广播。其中,有关电子提单所有权转移的内容可参见上述各实施例的相关内容。进口商收到该广播后会对电子提单的地址进行验证看所有权是否已转移给自己。这里电子提单的地址可以简单理解为该电子提单中的公钥是不是进口商自己的公钥。
货物到港后,进口商可针对该电子提单进行提单提货申请,船公司收到后该申请后会对该电子提单进行校验,校验通过后就让进口商提货,然后进行提单注销,提单状态置为400,并向全网广播。
区块链中的一个计算节点(亦或称交易打包节点)定时(比如5分钟、10分钟等)汇总合法交易(即处于合法状态的电子提单),根据时间戳对这些电子提单进行排序,然后打包成区块,并将区块发送给记账节点。
区块链中的一个计算节点(亦或称记账节点)接收到区块后对区块中的交易进行校验,校验通过后写入账本,并向全网广播。
这里需要说明的是:上述内容中涉及到的处理,均可参见上述各方法实施例中的步 骤。
本申请各实施例体用的技术方案基于区块链和多重签名技术,发明了一种数字化电子提单,实现提单的签发、流转、修改、提货、查询、校验、注销全流程线上化可跟踪、可视化,让提单的使用实现零费用、高效率(任何操作1分钟内搞定),并且保证提单的信息不可篡改、多中心服务节点存储并提供查验,避免单点故障等服务不可用的问题。
由上述场景实例可知,通过多重签名智能合约来保证提单的合法签发和修改,通过海关和货代平台的相关贸易单证协助交叉验证来提前发现提单信息的正确性和可信度,避免到最后清关时才发现问题发生纠纷,从而避免船公司、出口商、进口商的损失。多重签名避免个别参与方秘钥被盗的风险,造假者需要同时盗取三个签名方的秘钥才能完成签名,进一步杜绝提单造假。另外基于区块链的分布式多中心服务节点部署实现多节点可提供提单查验,避免单点故障等服务不可用问题,从而提高了服务的可用性。本区块链方案属于联盟链,tps能够达到1000级别,秒杀以太坊20tps和比特币7tps的低性能,同时交易仅局限联盟成员可见,还可以对敏感字段加密,避免交易隐私泄露,避免了公链全部数据公开的问题。
另外,本申请各实施例提供的技术方案使用区块链分布式多中心多节点部署方案,每个节点的接入平台均可提供提单的查验,避免了原来只有船公司的系统可供查验带来的单点故障、系统被破坏或攻击等问题,提高服务的可用性,基本可以保证查验服务百分百可用。此外,方案还借助CA认证机构实名认证所有参与方,然后通过数字签名验签的方式验证提单的申请人和审批机构的真实性,避免纸质提单的萝卜章造假问题。电子提单唯一性避免多份提单分开质押骗取融资问题和多人持有相同提单带来的纠纷问题。
本申请各实施例提供的技术方案可基于联盟链的方式来构建区块链平台,对性能和交易私密性都可以有保证,可避免使用公链简单开发DAPP带来的性能问题和保密性问题。交易仅局限联盟成员可见,还可以对敏感字段加密,避免交易隐私泄露,避免了公链全部数据公开的问题。
